Cevap: Configure a Cloud Storage bucket with Object Versioning and state locking enabled to store the Terraform remote state files securely.; Provision a Cloud SQL instance with regional High Availability enabled and configure it to use a Customer-Managed Encryption Key (CMEK) hosted in Cloud KMS.

Cevap

The architect must configure a Cloud Storage bucket with Object Versioning and state locking for Terraform remote state storage, and provision a Cloud SQL instance with regional High Availability encrypted using a Customer-Managed Encryption Key (CMEK) from Cloud KMS.
Provisioning a Cloud SQL instance with regional High Availability using Cloud KMS Customer-Managed Encryption Keys (CMEK) meets both the availability and compliance requirements for a regional relational database. Storing the Terraform state file in a remote Cloud Storage bucket with Object Versioning and state locking ensures concurrency protection and resilience against state corruption.

Adım Adım Çözüm

1
Identify the proper database provisioning configuration for regional high availability and encryption governance.
Cloud SQL configured with regional availability (primary and standby instances across zones) combined with CMEK via Cloud KMS fulfills both high availability and customer-managed key compliance.
Cloud SQL matches single-region relational database demands without introducing the cost or multi-region overhead of Cloud Spanner.
2
Determine the secure Infrastructure as Code (IaC) state management strategy.
Terraform state must be configured to use a remote Cloud Storage backend with Object Versioning and locking enabled.
This prevents race conditions during concurrent CI/CD pipeline executions and enables state recovery in case of accidental corruption.

Cevap: Provision Cloud Pub/Sub topics as the physical messaging middleware to asynchronously ingest telemetry streams before triggering Dataflow processing jobs.; Configure VPC Service Controls around BigQuery and Cloud Storage resource boundaries to prevent authorized users from exfiltrating data to external GCP projects.

Cevap

The optimal physical architecture requires provisioning Cloud Pub/Sub as the asynchronous messaging ingestion layer and establishing VPC Service Controls around storage and analytics services to enforce security boundaries.
The correct choices properly translate high-level conceptual requirements into concrete physical GCP services. Cloud Pub/Sub satisfies the logical decoupling requirement for high-throughput stream ingestion. VPC Service Controls satisfy the physical security requirement by preventing data exfiltration across resource perimeters.

Adım Adım Çözüm

1
Translate the conceptual requirement of decoupling high-volume ingestion streams into a physical GCP compute and messaging design.
Cloud Pub/Sub acts as the scalable physical buffer between ingestion sources and analytical processing pipelines.
Asynchronous messaging ensures system resiliency and temporal decoupling.
2
Translate the security requirement of preventing data exfiltration into a physical network and resource perimeter design.
VPC Service Controls define a security perimeter around sensitive data stores like BigQuery and Cloud Storage.

An enterprise digital healthcare platform on Google Cloud ingests real-time patient telemetry streams via Cloud Pub/Sub and processes them using a microservices pipeline backed by Cloud Spanner. The contract specifies a customer SLA of 99.9% availability, defined as telemetry processing latency staying under 1.5 seconds. During peak events, while the frontend HTTP Load Balancer immediately acknowledges incoming requests with HTTP 200, downstream processing queue backpressure causes ingestion processing times to frequently exceed 3 seconds. Consequently, the company incurs contract financial penalties despite internal metrics showing 99.99% HTTP request success rates. Which TWO actions should the Site Reliability Engineering (SRE) and business teams take to align technical service levels with business objectives and prevent SLA breaches?

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: Define the Service Level Indicator (SLI) as the proportion of valid telemetry events whose end-to-end processing latency from ingestion to database write is under 1.5 seconds, and set the internal Service Level Objective (SLO) at 99.95%.; Establish an error budget policy that automatically halts new feature deployments and shifts engineering focus to database throughput optimization whenever the multi-window burn rate indicates the error budget will deplete before the end of the compliance cycle.

Cevap

The team should define the SLI based on end-to-end processing latency under 1.5 seconds with an internal SLO of 99.95%, and establish an error budget policy that halts feature deployments when error budget burn rates threaten SLA compliance.
The correct architectural strategy involves capturing true end-to-end processing latency as the SLI, setting an internal SLO tighter than the external SLA to build a safety buffer, and enforcing error budget policies that prioritize reliability over new features when the burn rate indicates an impending breach.

Adım Adım Çözüm

1
Analyze the misalignment between technical metrics and business SLAs.
The current technical metric (HTTP 200 success rate at the load balancer) reports 99.99% availability, but downstream queue backpressure causes actual latency (>3 seconds) to breach the business SLA threshold (1.5 seconds).
SLIs must reflect actual user/business experience rather than proxy metrics at ingestion boundaries.
2
Define an accurate SLI and internal SLO safety buffer.
SLI = (Valid events processed under 1.5s) / (Total valid events). Setting an internal SLO of 99.95% creates a 0.05% safety margin relative to the 99.9% customer SLA.
Internal SLOs should always be stricter than external SLAs to allow proactive mitigation before financial penalties occur.
3
Establish governance based on error budget burn rates.
When error budget consumption burns at a rate that threatens the compliance window, product releases are frozen and engineering effort is redirected to reliability and backpressure remediation.
Error budget policies bridge technical metrics and business decision-making by balancing velocity with reliability risk.

An organization is establishing Site Reliability Engineering (SRE) practices on Google Cloud to ensure technical monitoring aligns with business performance goals. Which TWO of the following statements accurately describe the definitions and strategic roles of Service Level Indicators (SLIs) and Service Level Objectives (SLOs)?

Geçerli olan tümünü seçin

Cevabı ve açıklamayı göster

Cevap: A Service Level Indicator (SLI) is a quantifiable metric that measures actual service performance, such as the proportion of successful HTTP requests.; A Service Level Objective (SLO) is an internal target goal for an SLI, set to preserve user experience and protect against Service Level Agreement (SLA) breaches.

Cevap

The correct answers are the statements asserting that an SLI is a quantifiable metric measuring real-time performance (e.g., successful request ratio) and that an SLO is an internal target goal for an SLI established to safeguard user experience prior to SLA breaches.
The statements defining an SLI as the quantifiable metric measuring actual performance and an SLO as an internal target goal designed to protect user experience and prevent SLA breaches are both correct. SLIs quantify compliance in real time, while SLOs establish acceptable thresholds that guide engineering reliability priorities and error budget management.

Adım Adım Çözüm

1
Differentiate between metric collection (SLI) and target definition (SLO).
Recognize that an SLI represents what is measured (e.g., latency, error rate), whereas an SLO represents the target threshold for that metric (e.g., 99.9%99.9\% success over 30 days).
Clear separation between indicators and objectives prevents metric misconfiguration and ensures operational clarity.
2
Align internal target goals (SLOs) with business contracts (SLAs).
Confirm that internal SLOs must be stricter than external SLAs to create an error budget cushion.
Maintaining tighter internal targets ensures teams can intervene before contractual breaches incur business liabilities.
3
Evaluate availability targets against engineering realities.
Reject 100%100\% availability targets because an error budget is required to innovate and deploy changes safely.
Pursuing 100%100\% uptime is economically unfeasible and stifles feature velocity.

Cevap: Export Cloud Billing data to BigQuery to enable granular cost analysis and custom visualization dashboards.; Configure Cloud Billing budgets with programmatic Pub/Sub notifications to alert teams when spent thresholds are reached.

Cevap

The correct practices are exporting Cloud Billing data to BigQuery for granular cost reporting and configuring Cloud Billing budgets with programmatic notifications to alert teams of spending thresholds.
Exporting Cloud Billing data to BigQuery enables deep custom analytics, trend reporting, and cost allocation visualizations across projects. Combining this with Cloud Billing budgets and Pub/Sub notifications ensures proactive alerting when spending approaches specified financial limits.

Adım Adım Çözüm

1
Analyze FinOps governance requirements for cost visibility and proactive budgeting.
Identified BigQuery billing export as the standard tool for detailed cost analysis and custom reporting, and Billing Budgets with alerts as the key mechanism for cost control.
Effective FinOps requires granular data for analysis alongside automated alerting to prevent cost overruns.
2
Evaluate the commitment model for variable workloads.
Rejected long-term Committed Use Discounts for unpredictable short-term workloads.
CUDs require predictable baseline usage to deliver financial savings; applying them to fluctuating workloads creates unutilized commitments.
3
Evaluate resource selection and IAM privileges.
Rejected using Cloud Spanner for simple relational workloads and rejected primitive Owner roles.
Cloud Spanner incurs high baseline costs unsuited for small workloads, and primitive IAM roles violate least privilege governance.

A global gaming enterprise is preparing to migrate its high-throughput real-time telemetry ingestion platform to Google Cloud ahead of an international game release. Business stakeholders require zero service disruption during the launch window and strict compliance with corporate data exfiltration controls. However, an organizational readiness assessment reveals that the operations team lacks experience with GCP administrative workflows, and the planned architecture requires 50,000 Compute Engine vCPUs in a single GCP region. As the Lead Cloud Architect responsible for stakeholder alignment and change management, which strategy should you implement to satisfy technical requirements while ensuring operational readiness?

Cevabı ve açıklamayı göster

Cevap: Initiate regional quota increase requests far in advance of the launch date, establish a structured role-based training program for the operations team, and enforce VPC Service Controls around telemetry storage resources.

Cevap

The optimal strategy is to initiate regional quota increase requests well in advance of deployment, establish a structured role-based enablement program for the operations team, and enforce VPC Service Controls around perimeter resources.
The correct strategy combines technical provisioning lead-time planning (requesting quota increases in advance), organizational enablement (structured training programs for operational readiness), and security perimeter enforcement (VPC Service Controls to satisfy exfiltration constraints).

Adım Adım Çözüm

1
Analyze capacity requirements and quota lead times
Identified that provisioned infrastructure requires 50,000 regional vCPUs, which exceeds default quotas and requires early submission to GCP support.
Large-scale quota requests require validation and allocation lead time prior to go-live.
2
Evaluate organizational change management and team readiness factors
Formulated a role-based enablement roadmap to upskill operations personnel on GCP management.
Lack of team operational experience represents a risk to application stability during launch.
3

A global enterprise operates a high-throughput financial transactions processing platform on Google Cloud with a primary deployment in region us-east4 and a designated disaster recovery (DR) site in us-west1. The database layer utilizes Cloud SQL cross-region read replicas, while microservices run on Google Kubernetes Engine (GKE). The organization is finalizing standard operating procedures for periodic, non-disruptive DR validation drills designed to verify an RTO of 1 hour and an RPO of 5 minutes. Which TWO procedures must the cloud architect include in the DR validation execution plan to ensure accurate validation without disrupting active production operations or causing drill failures? (Select 2 answers.)

Cevabı ve açıklamayı göster

Cevap: Submit regional resource quota increase requests for GKE compute nodes and IP addresses in the secondary region (us-west1) well before executing the validation drill.; Perform validation testing against a isolated clone or point-in-time recovery (PITR) instance derived from the secondary database, preserving continuous cross-region replication from production.

Cevap

The correct procedures are to request regional compute/network quota increases in the secondary region prior to the drill and to perform database validation against a cloned or point-in-time recovery copy rather than promoting the live production cross-region replica.
To execute a non-disruptive disaster recovery drill, organizations must ensure the secondary region has adequate quota to host production workloads by requesting quota increases prior to the test. Additionally, to avoid disrupting production database replication streams, testing must occur on isolated database snapshots or cloned instances rather than promoting the active replica.

Adım Adım Çözüm

1
Analyze capacity requirements in the target DR region.
Identified potential quota bottlenecks in GKE compute resources and networking in us-west1 during full workload deployment.
Default quotas in secondary regions may not match primary production scale, leading to provisioning errors during failover testing.
2
Evaluate database validation strategies for non-disruptive testing.
Selected creating a database clone or point-in-time recovery copy in us-west1.
Promoting a live cross-region replica disconnects it from the primary instance, severing continuous data replication and violating production RPO requirements.
3
Verify overall DR validation procedure compliance against RTO and RPO goals.
Confirmed that pre-provisioning quota and isolating test data fulfills both seamless failover verification and production stability.
Allows thorough validation of failover automation while keeping production environment fully operational and protected.

Anahtar Kavram

Developing non-disruptive Business Continuity and Disaster Recovery (BCP/DR) validation procedures on Google Cloud requires pre-verifying regional capacity/quotas and maintaining continuous production replication by conducting tests on cloned isolated environments.

An enterprise is migrating sensitive operational audit logs to Google Cloud. The compliance framework mandates that data stored at rest in Cloud Storage buckets and BigQuery datasets must be encrypted using Customer-Managed Encryption Keys (CMEK) hosted in Cloud KMS. The security team mandates strict separation of duties: storage administrators must not manage encryption keys, and key administrators must not access stored log data. Additionally, key rotation must occur automatically without requiring manual re-encryption of existing historical data. Which TWO architectural configuration steps must you perform to meet these requirements? (Select TWO)

Cevap: Grant the Cloud KMS CryptoKey Encrypter/Decrypter role on the specific KMS key to the Cloud Storage and BigQuery service agents, ensuring key management permissions remain restricted to the security team.; Configure an automated rotation schedule on the Cloud KMS CryptoKey so that new key versions are generated periodically while older key versions remain available for decryption.

Cevap

Granting the Cloud KMS CryptoKey Encrypter/Decrypter role to the Google-managed service agents enforces separation of duties, and configuring an automated key rotation schedule on the Cloud KMS CryptoKey ensures seamless encryption of new data while preserving access to historical data.
Granting the Cloud KMS CryptoKey Encrypter/Decrypter role directly to service agents ensures strict separation of duties and least privilege compliance. Furthermore, setting up an automated key rotation schedule on the Cloud KMS CryptoKey allows GCP services to use the latest key version for new writes while retaining older versions to read legacy data without manual re-encryption.

Adım Adım Çözüm

1
Identify key management and separation of duties requirements for CMEK.
Determine that service agents require cryptographic access via fine-grained roles rather than primitive permissions.
Google Cloud service agents (e.g., BigQuery and Cloud Storage service accounts) perform encryption and decryption on behalf of users when configured with CMEK.
2
Configure IAM permissions using least privilege.
Grant roles/cloudkms.cryptoKeyEncrypterDecrypter on the key to the service agents.
This allows the service agents to encrypt/decrypt data without granting human administrators cross-domain access.
3
Configure key rotation settings in Cloud KMS.
Enable automated rotation schedules on the Cloud KMS CryptoKey.
Cloud KMS automatically uses the new primary key version for encrypting newly written data while maintaining old versions for decrypting existing data.

Cevap

Google-default Encryption matches automatic AES-256 encryption managed by Google without configuration. CMEK matches keys generated/stored in Cloud KMS with customer-controlled lifecycle and IAM permissions. CSEK matches customer-supplied raw 256-bit keys provided per API call with no GCP key persistence. Cloud EKM matches key material residing outside GCP in a third-party/on-premises HSM accessed via Cloud KMS.
Each key management tier represents a distinct boundary of operational responsibility and key location: Google-default is fully automated; CMEK stores keys in GCP Cloud KMS with customer-managed IAM/rotation policies; CSEK transiently receives raw customer keys per API call; Cloud EKM keeps master key material inside an external non-GCP HSM.

Adım Adım Çözüm

1
Analyze the operational control and key location for Google-default Encryption.
Identified that Google manages key generation, rotation, and storage automatically without customer configuration (matches statement describing default AES-256 with zero setup).
Google-default encryption is enabled out-of-the-box for all GCP storage services.
2
Differentiate CMEK from CSEK based on key persistence and KMS involvement.
CMEK utilizes Cloud KMS within GCP to manage key lifecycles, IAM service agent permissions, and rotation schedules. CSEK requires passing raw key material in API headers directly, retaining zero key material in Cloud KMS.
CMEK delegates storage to Cloud KMS, whereas CSEK keeps key management completely external to GCP and passes key headers transiently.
3
Evaluate the architectural pattern for Cloud EKM.
Cloud EKM connects Cloud KMS to an external physical HSM infrastructure outside of GCP, ensuring the master key material never leaves the external HSM.
Regulatory compliance may mandate physical separation of cryptographic key storage from cloud service providers.

Cevap: Configure Cloud Build triggers to execute using a user-managed service account bound to specific fine-grained IAM roles, and configure a Cloud Storage backend with object versioning for Terraform state storage.; Restrict manual Console modifications by enforcing Organization Policies, and mandate that all infrastructure state modifications be applied exclusively through automated Cloud Build pipeline triggers.

Cevap

The organization must configure Cloud Build triggers to run with a least-privilege user-managed service account, utilize Cloud Storage with object versioning for centralized Terraform state management, enforce Organization Policies to block manual Console edits, and restrict infrastructure deployments exclusively to automated CI/CD pipeline triggers.
Securing enterprise CI/CD pipelines requires replacing over-privileged default build service accounts with fine-grained custom service accounts, locking down infrastructure changes to version-controlled automated build triggers, and persisting IaC state in a centralized Cloud Storage backend with object versioning and state locking.

Cevap

The correct operational sequence begins with Cloud Build constructing the container image, followed by Artifact Analysis performing vulnerability scans, storing the image and signing an attestation in Artifact Registry, enforcing security policies through Binary Authorization, and concluding with Cloud Deploy releasing the image to GKE.
The sequence reflects Google Cloud secure software supply chain best practices: first, Cloud Build packages the application; second, Artifact Analysis performs vulnerability scanning; third, the artifact is stored in Artifact Registry with a signed attestation; fourth, Binary Authorization verifies the attestation signature against organizational policy; and fifth, Cloud Deploy delivers the image to production GKE.

Adım Adım Çözüm

1
Trigger continuous integration and build artifact
Cloud Build compiles source code into a runnable container image.
The source code must be packaged into a container artifact before security scanning can begin.
2
Execute automated security vulnerability analysis
Artifact Analysis scans the container layers for known vulnerabilities.
Security scanning must occur before certifying that an image is safe for environment promotion.
3
Persist image artifact and sign cryptographic attestation
Container image is pushed to Artifact Registry alongside a KMS-signed attestation.
Attestations provide tamper-proof proof that security compliance gates were passed.
4
Enforce container deployment policies
Binary Authorization verifies that valid attestations exist before allowing deployment.
Policy enforcement prevents unsigned or non-compliant images from reaching GKE cluster nodes.
5
Execute progressive release pipeline
Cloud Deploy manages the canary rollout to the production GKE cluster.
Actual deployment execution is the final step in the continuous delivery pipeline.

Cevap: Define a Service Level Indicator (SLI) measuring the ratio of successful checkout transactions completed under 500 milliseconds, and set a Service Level Objective (SLO) based on the latency threshold where customer purchase drop-off increases.

Cevap

Define a Service Level Indicator (SLI) measuring the ratio of successful checkout transactions completed under 500 milliseconds, and set a Service Level Objective (SLO) based on the latency threshold where customer purchase drop-off increases.
The correct approach ties the technical metric (checkout latency and success rate) directly to user impact and business performance. In SRE practices, SLIs should measure user-centric experiences (such as request latency on key transactions), and SLO targets should be calibrated against business tolerances, such as conversion rate impact.

Adım Adım Çözüm

1
Identify the key business goal and user journey
The business goal is preventing lost revenue during sales events, which directly relates to the end-user checkout experience.
Technical service levels must be tied to user experience metrics that drive business outcomes.
2
Distinguish between SLI, SLO, and infrastructure metrics
SLI is the measured quantitative metric (e.g., successful fast requests / total requests). SLO is the target goal set for that SLI (e.g., 99.5% fast requests).
System resource utilization (like CPU/RAM) does not directly reflect whether users are successfully completing purchases.
3
Select the strategy aligning technical SLI/SLO with business impact
Measuring latency on successful checkouts and setting SLO targets tied to user conversion degradation achieves business alignment.
This ensures engineering efforts and error budget management focus directly on user experience and business value.

Cevap

Advise the team to create a dedicated user-managed service account attached to the Compute Engine instances, use Workload Identity for GKE integrations, and grant fine-grained, minimum-required predefined IAM roles scoped strictly to target projects.
The architect should advise creating a dedicated, user-managed service account attached to the Compute Engine deployment instances. Using Workload Identity allows GKE workloads to securely interact with Google Cloud APIs using short-lived tokens without storing credentials. Granting fine-grained predefined roles at the project level strictly satisfies the principle of least privilege while keeping management overhead low.

Adım Adım Çözüm

Analyze identity requirements for automated workloads on Compute Engine and GKE.
Identified that default service accounts contain excessive default access or primitive roles that breach compliance.
Default service accounts should not be used in enterprise production deployment pipelines.
2
Evaluate authentication and credential management mechanisms.
Determined that service account keys should be avoided in favor of VM metadata tokens and Workload Identity.
Workload Identity and attached service accounts use short-lived, automatically rotated tokens without long-lived key risks.
3
Select least-privilege IAM roles scoped to the appropriate resource boundaries.
Configured fine-grained predefined roles at the project level instead of primitive roles at the folder level.
Predefined roles restrict permissions to only what is strictly necessary for deployment pipelines.

The FinOps lead wants to minimize compute costs for this steady-state workload without modifying the application code or infrastructure architecture. Which cost optimization strategy should be implemented?

Cevabı ve açıklamayı göster

Cevap: Purchase 3-year Committed Use Discounts (CUDs) for the baseline Compute Engine instances.

Cevap

Purchasing 3-year Committed Use Discounts (CUDs) for the baseline Compute Engine instances is the optimal cost optimization strategy.
Purchasing Committed Use Discounts (CUDs) is the recommended FinOps practice for predictable, 24/7 workloads planned for 1 to 3 years. It yields maximum cost savings on Compute Engine without changing application code or architecture.

Adım Adım Çözüm

1
Analyze the workload characteristics
The application requires continuous 24/7 execution with predictable resource utilization over a 3-year horizon.
Cost optimization strategies depend on whether a workload is steady-state, bursty, or short-lived.
2
Evaluate Google Cloud cost optimization models
Committed Use Discounts (CUDs) provide deep discounts for committed baseline capacity over 1 or 3 years without application refactoring.
CUDs guarantee discounted pricing for committed resource usage without operational risk of preemption.

Cevap: Configure Cloud Storage Object Lifecycle Management rules to move processed logs to Nearline or Coldline storage after 30 days.; Migrate the low-traffic internal web service from a dedicated virtual machine to Cloud Run to benefit from scale-to-zero pricing.

Cevap

Implementing Object Lifecycle Management rules to transition log data to colder storage classes and deploying the low-traffic web service to Cloud Run.
Transitioning logs to Nearline or Coldline storage using lifecycle policies reduces storage unit costs for aging data. Hosting low-traffic web apps on Cloud Run ensures billing only occurs when requests are processed, eliminating idle server cost.

Adım Adım Çözüm

1
Analyze storage cost optimization options for batch log data
Identify Object Lifecycle Management as the mechanism to move older logs from Standard storage to Nearline or Coldline storage, lowering cost per gigabyte.
Infrequently accessed historical logs do not require high-frequency retrieval storage classes.
2
Analyze compute cost optimization for low-traffic applications
Select serverless container hosting on Cloud Run.
Cloud Run scales to zero instances when idle, preventing charges for unused VM CPU and memory capacity.

An enterprise security architect is designing an automated deployment pipeline to provision Cloud SQL database instances encrypted with Customer-Managed Encryption Keys (CMEK). The encryption keys reside in a centralized Cloud KMS key ring within a dedicated security project, while the databases are deployed in separate workload projects. During deployment, the Cloud SQL instance creation fails due to missing access permissions on the encryption key. A DevOps engineer recommends assigning the Editor primitive IAM role on the security project to resolve the access issue. Which solution complies with Google Cloud security best practices while enforcing the principle of least privilege?

Cevabı ve açıklamayı göster

Cevap: Grant the Cloud KMS CryptoKey Encrypter/Decrypter role (roles/cloudkms.cryptoKeyEncrypterDecrypter) on the specific KMS key to the Cloud SQL Service Agent account ([email protected]).

Cevap

Grant the Cloud KMS CryptoKey Encrypter/Decrypter role on the specific key to the Cloud SQL Service Agent account for the workload project.
The correct solution grants the predefined Cloud KMS CryptoKey Encrypter/Decrypter role directly on the specific encryption key to the target project's Cloud SQL Service Agent. In Google Cloud, service-managed operations like database disk encryption require the service agent identity to have explicit key usage permissions. Applying this role at the key resource level adheres strictly to the principle of least privilege.

Adım Adım Çözüm

1
Identify the identity responsible for performing encryption/decryption operations for Cloud SQL.
GCP services use specialized Service Agents (e.g., [email protected]) rather than generic user accounts or custom service accounts to perform CMEK operations.
When configuring CMEK, the service itself must be authorized to interact with Cloud KMS on behalf of the project.
2
Determine the least-privileged IAM role required for Cloud KMS operations.
The predefined role roles/cloudkms.cryptoKeyEncrypterDecrypter provides permission to encrypt and decrypt data using Cloud KMS keys.
Granting fine-grained resource-level roles on the specific key prevents over-privileging the service account with key administration rights or broad project permissions.
3
Evaluate and eliminate non-compliant or misconfigured architectural options.
Primitive Editor roles violate least privilege, CSEK is unnecessary and unsupported for Cloud SQL, and VPC Service Controls do not supersede IAM authorization.
Ensures adherence to GCP security design guidelines for multi-project CMEK topologies.

A software security firm is deploying a sensitive workload on Google Compute Engine that requires customer-managed encryption keys (CMEK) hosted in Cloud KMS for persistent disk encryption. Corporate policy mandates a strict separation of duties: compute infrastructure administrators must manage virtual machine lifecycles, but they must NOT have access to read, decrypt, or manage cryptographic key materials directly. You need to configure IAM access control to meet these requirements. Which TWO actions should you perform? (Select TWO.)

Cevap: Grant the Compute Engine Service Agent the Cloud KMS CryptoKey Encrypter/Decrypter role on the target Cloud KMS key.; Grant compute infrastructure administrators the Compute Admin role while withholding Cloud KMS Admin and Cloud KMS CryptoKey Encrypter/Decrypter roles.

Cevap

Grant the Compute Engine Service Agent the Cloud KMS CryptoKey Encrypter/Decrypter role on the target key, and assign compute infrastructure administrators the Compute Admin role without Cloud KMS key management permissions.
To implement CMEK on Compute Engine persistent disks while enforcing separation of duties, the Compute Engine Service Agent must be granted the Cloud KMS CryptoKey Encrypter/Decrypter role so that Google Cloud infrastructure can encrypt and decrypt disk blocks. Simultaneously, human compute administrators should receive only compute-related predefined roles (such as Compute Admin) without Cloud KMS roles, ensuring they can manage virtual machines without gaining access to encryption keys.

Adım Adım Çözüm

1
Identify the service principal responsible for encryption operations
Recognize that Compute Engine uses its service agent (e.g., [email protected]) to access Cloud KMS keys for persistent disks.
Google Cloud service agents perform cryptographic disk operations under CMEK architectures.
2
Configure key access permissions for the service agent
Grant the Cloud KMS CryptoKey Encrypter/Decrypter role specifically to the Compute Engine Service Agent on the specified key.
This allows Google Cloud to handle encryption/decryption transparently on disk attachment without granting human administrators access to key material.
3
Enforce separation of duties for human administrators
Grant human administrators the Compute Admin role while omitting Cloud KMS permissions.
This ensures compute administrators can create and maintain virtual machines while satisfying compliance rules against direct cryptographic key access.
