An organization is operating three Virtual Private Cloud (VPC) networks in Google Cloud: vpc-frontend, vpc-hub, and vpc-backend. To centralize administration, vpc-frontend is peered with vpc-hub, and vpc-backend is also peered with vpc-hub. Compute Engine instances in vpc-frontend need to communicate directly with internal workloads in vpc-backend. Network administrators observe that traffic sent from vpc-frontend to vpc-backend is dropped, even though both networks are successfully peered with vpc-hub. Which network topology modification should be implemented to enable connectivity between vpc-frontend and vpc-backend?

Cevabı ve açıklamayı göster

Cevap: Establish a direct VPC Network Peering connection between vpc-frontend and vpc-backend.

Cevap

Establish a direct VPC Network Peering connection between vpc-frontend and vpc-backend.
VPC Network Peering in Google Cloud is explicitly non-transitive. Traffic originating in one peered network cannot traverse a intermediate network to reach a third network. To allow direct communication between two spoke VPC networks, an explicit direct VPC Network Peering connection must be established between them.

Adım Adım Çözüm

1
Identify the routing constraint in Google Cloud VPC Network Peering.
VPC Network Peering is strictly non-transitive. If VPC A is peered with VPC B, and VPC B is peered with VPC C, traffic from VPC A cannot reach VPC C through VPC B.
Google Cloud VPC routing rules suppress incoming peered traffic from being re-transmitted out through another peering interface.
2
Evaluate potential solutions to allow communication between vpc-frontend and vpc-backend.
Creating a direct VPC Network Peering link between vpc-frontend and vpc-backend allows both networks to exchange subnet routes directly.
Direct peering satisfies the non-transitive requirement while maintaining low-latency, internal Google network routing without performance bottlenecks.

Cevap: Apply Spend-Based Flexible Committed Use Discounts (CUDs) at the Cloud Billing Account level for baseline compute and database usage, leverage Cloud Run request-driven scaling for telemetry processing bursts, and configure Organization-level budgets with Pub/Sub notifications for automated cost governance.

Cevap

Apply Spend-Based Flexible Committed Use Discounts (CUDs) at the Cloud Billing Account level for baseline compute and database usage, leverage Cloud Run request-driven scaling for telemetry processing bursts, and configure Organization-level budgets with Pub/Sub notifications for automated cost governance.
The correct strategy combines Spend-Based Flexible Committed Use Discounts (CUDs) at the Cloud Billing Account level to cover predictable baseline spend across projects with request-based serverless autoscaling (Cloud Run) for unpredictable spikes. Furthermore, binding Organization-level Cloud Budgets to Pub/Sub enables automated FinOps remediation without operational or security compromises.

Adım Adım Çözüm

1
Analyze workload predictability and separate steady-state baseline consumption from bursty workloads.
Identified steady API traffic suitable for commitments and unpredictable telemetry processing requiring dynamic scaling.
Applying long-term financial commitments to unpredictable workloads causes over-commitment waste, while paying on-demand rates for steady baselines wastes potential discount opportunities.
2
Select appropriate commitment models and serverless scaling components for each workload profile.

Cevap: Configure a Remote Backend using a Google Cloud Storage bucket with object versioning enabled and strict IAM permissions for state storage.; Replace primitive project Owner roles on deployment service accounts with least-privilege predefined or custom IAM roles scoped strictly to required infrastructure resources.

Cevap

The correct architecture refactoring steps are configuring a Cloud Storage remote backend with object versioning for central Terraform state management, and replacing primitive Owner roles on continuous deployment service accounts with granular, least-privilege IAM roles.
Migrating to a Cloud Storage remote backend with object versioning solves state file concurrency conflicts and durability risks. Concurrently, replacing primitive project Owner roles with least-privilege predefined or custom IAM roles establishes robust security governance and eliminates privilege escalation vulnerabilities.

Adım Adım Çözüm

1
Address IaC state management technical debt
Provision a secure Cloud Storage bucket configured with state locking and object versioning, moving local state to a managed remote backend.
Centralizing Terraform state prevents state drift, concurrency collisions, and loss of state file assets across isolated developer environments.
2
Remediate IAM security technical debt
Audit the exact permissions required by CI/CD pipelines and replace the primitive Owner role with fine-grained custom or predefined roles.
Removing primitive roles mitigates risk of privilege escalation and enforces least privilege access across deployment automation.

Cevap: Execute Cloud Build build jobs using Cloud Build Private Pools attached to a peered VPC network within a VPC Service Controls perimeter. Maintain Terraform state in a Cloud Storage backend with object versioning and state locking enabled, and grant the pipeline service account fine-grained resource roles along with roles/iam.serviceAccountUser on target workload service accounts.

Cevap

Execute Cloud Build build jobs using Cloud Build Private Pools attached to a peered VPC network within a VPC Service Controls perimeter. Maintain Terraform state in a Cloud Storage backend with object versioning and state locking enabled, and grant the pipeline service account fine-grained resource roles along with roles/iam.serviceAccountUser on target workload service accounts.
The solution utilizing Cloud Build Private Pools inside a VPC Service Controls perimeter provides complete network isolation without public IP exposure. Using a Cloud Storage backend configured with state locking and object versioning ensures concurrent Terraform executions do not corrupt state files. Finally, assigning fine-grained predefined roles paired with the Service Account User role enforces strict least privilege without granting administrative control over service accounts.

Adım Adım Çözüm

1
Establish secure network execution environment
Cloud Build Private Pools peered to a private VPC within a VPC Service Controls perimeter block internet exposure and prevent unauthorized data egress.
Standard Cloud Build pools run in multi-tenant environments without native VPC access, making Private Pools necessary for private GKE cluster interaction and VPC Service Controls enforcement.
2
Configure secure IaC state management
Using Google Cloud Storage as a remote Terraform backend with object versioning and state locking enabled ensures concurrency control and disaster recovery.
Local or unversioned state storage leads to race conditions, state drift, and vulnerability to corruption during continuous integration pipelines.
3
Apply least-privilege IAM controls for pipeline execution
Granting granular roles and roles/iam.serviceAccountUser allows the pipeline service account to attach workload identities to GKE resources without full administrative access.
Granting primitive roles or service account admin rights creates excessive permissions and risks privilege escalation.

Cevap: Import existing GCP resources into a version-controlled Infrastructure as Code state managed in Cloud Storage with object locking, replace primitive permissions with fine-grained predefined roles following least privilege, and enforce all changes through an automated CI/CD deployment pipeline.

Cevap

Import existing GCP resources into a version-controlled Infrastructure as Code state managed in Cloud Storage with object locking, replace primitive permissions with fine-grained predefined roles following least privilege, and enforce all changes through an automated CI/CD deployment pipeline.
The correct answer systematically addresses both security and operational debt by locking infrastructure configurations into IaC backed by centralized state storage, restricting deployment access strictly to CI/CD pipelines, and applying least-privilege IAM roles to eliminate broad administrative access.

Adım Adım Çözüm

1
Identify accumulated cloud technical debt areas
Discovered manual console modifications (configuration drift) and overly broad primitive IAM roles on application service accounts.
Technical debt assessment requires pin-pointing operational risk and security exposure in the current architecture.
2
Establish Infrastructure as Code (IaC) governance
Import resources into IaC state stored centrally in Cloud Storage with state locking and versioning, enforcing deployment strictly through automated CI/CD pipelines.
Automated pipelines eliminate manual console drift and establish auditable, reproducible deployment practices.
3
Remediate IAM security technical debt
Revoke primitive Owner roles and grant minimal, task-specific predefined or custom IAM roles.
Enforcing the principle of least privilege limits the impact of compromised service accounts and satisfies compliance requirements.

An enterprise DevOps team is setting up an automated CI/CD pipeline using Cloud Build to provision cloud infrastructure via Terraform. To adhere to security governance, the build execution must run using a dedicated deployment service account with minimal IAM privileges rather than elevated project-level permissions. Which IAM role configuration should you implement to allow the Cloud Build service account to act as the deployment service account?

Cevabı ve açıklamayı göster

Cevap: Grant the Service Account User role (roles/iam.serviceAccountUser) to the Cloud Build service account on the deployment service account resource.

Cevap

Grant the Service Account User role (roles/iam.serviceAccountUser) to the Cloud Build service account on the specific deployment service account resource.
To allow a CI/CD build runner such as Cloud Build to impersonate a dedicated deployment identity, the Cloud Build service account must be granted the Service Account User role directly on the deployment service account resource. This provides the minimum privilege required to execute jobs under that identity.

Adım Adım Çözüm

1
Determine the identity initiating the pipeline execution and the target identity needed for deployment.
Cloud Build runs using its service account, which needs to attach or act as a dedicated deployment service account.
Separating build triggers from execution service accounts enforces security boundary controls.
2
Identify the minimum necessary role for service account impersonation.
The Service Account User role (`roles/iam.serviceAccountUser`) allows an identity to impersonate or attach a specified service account.
This role grants usage permissions without providing administrative controls over the service account lifecycle.
3
Apply the role binding at the specific service account resource level.
The Cloud Build service account is granted `roles/iam.serviceAccountUser` directly on the target deployment service account.
Binding at the resource level restricts usage rights exclusively to the designated service account.

A DevOps team is establishing a secure continuous delivery pipeline on Google Cloud to deploy microservices to Google Kubernetes Engine (GKE) using Cloud Build, Artifact Registry, Binary Authorization, and Cloud Deploy. Place the operational steps of the deployment pipeline in the correct chronological order from initial code commit to final production deployment.

Öğeleri doğru sıraya koymak için sürükleyin

Cevabı ve açıklamayı göster

Cevap

The correct chronological order of the CI/CD pipeline execution is: (1) Push source code to Git to trigger Cloud Build, (2) Execute tests, build the container image, and push it to Artifact Registry, (3) Perform vulnerability scanning and sign a Binary Authorization attestation, (4) Create a Cloud Deploy release to deploy the workload to the staging cluster under Binary Authorization policy enforcement, and (5) Promote the release rollout to the production cluster upon validation.
The deployment sequence follows secure software supply chain best practices on Google Cloud: Source control trigger -> Cloud Build artifact generation -> Binary Authorization attestation signing -> Staging deployment via Cloud Deploy -> Production promotion.

Adım Adım Çözüm

1
Trigger continuous integration upon code commit.
Cloud Build pipeline execution is initiated by Git repository webhook integration.
CI pipelines begin with source code updates to validate changes early.
2
Build and store the container image.
Container image is compiled, verified via unit tests, and published to Google Cloud Artifact Registry.
Centralizing artifacts in Artifact Registry is required before vulnerability scanning or deployment can take place.
3
Enforce supply chain security via digital attestations.
Binary Authorization attestation is generated using Cloud KMS after security checks pass.
Binary Authorization policy mandates that container images carry valid signed attestations prior to cluster deployment.
4
Deploy workload to staging via Cloud Deploy.
Cloud Deploy creates a release and provisions the deployment into the staging GKE cluster.
Deploying to non-production environments first ensures runtime stability and validation before production promotion.
5
Promote release to production target.
Cloud Deploy executes the production deployment rollout.
Promoting through predefined target delivery pipelines guarantees progressive and reliable release management.

A financial services organization is preparing to deploy a core transaction processing workload into a newly provisioned Google Cloud project. The architecture requires provisioning 250 Compute Engine N2 instances totaling 1,000 vCPUs in the `us-east4` region. During automated pre-deployment validation, the Infrastructure as Code (IaC) pipeline fails, reporting that the requested vCPU count exceeds default project limits. Which action should the Cloud Architect take to resolve this deployment blocker?

Cevabı ve açıklamayı göster

Cevap: Submit a regional quota increase request for N2 vCPUs in the us-east4 region via the Google Cloud Console or Quotas API prior to running the deployment pipeline.

Cevap

Submit a regional quota increase request for N2 vCPUs in the us-east4 region via the Google Cloud Console or Quotas API prior to running the deployment pipeline.
Submitting a regional vCPU quota increase request directly addresses capacity enforcement in Google Cloud. Google Cloud enforces quotas on Compute Engine resources (such as vCPUs per machine series per region) to manage infrastructure capacity. When workload requirements exceed standard default project limits, an explicit request must be submitted via the Cloud Console or IAM/Quotas API before deployment.

Adım Adım Çözüm

1
Identify the cause of the deployment failure
Recognize that the requested vCPU capacity exceeds default Google Cloud regional quota limits for the N2 machine family in `us-east4`.
GCP projects start with default quota allocations to prevent accidental over-provisioning and resource exhaustion.
2
Evaluate the appropriate GCP management mechanism
Determine that resource limits are controlled via Quotas rather than IAM permissions, CUD billing contracts, or IaC state configurations.
Quotas strictly enforce operational bounds independently of IAM roles or billing discount structures.
3
Formulate the proactive resolution step
Request an increase for the regional N2 vCPU quota in `us-east4` through the Cloud Console or Quotas API.
Proactive quota pre-provisioning ensures necessary capacity is allocated and approved before executing large-scale automated deployments.

A software development team is building a service that publishes and consumes messages using Google Cloud Pub/Sub. To facilitate fast offline testing without incurring cloud resource charges, a developer starts the Pub/Sub emulator locally using the command `gcloud beta emulators pubsub start`. Which environment variable must be set in the local application environment to ensure the Google Cloud Client Libraries automatically route requests to the local emulator instead of live GCP endpoints?

Cevabı ve açıklamayı göster

Cevap: PUBSUB_EMULATOR_HOST set to the host and port of the running emulator (e.g., localhost:8085)

Cevap

The environment variable PUBSUB_EMULATOR_HOST must be set to the emulator's host and port address (for example, localhost:8085).
Google Cloud Pub/Sub client libraries automatically check for the presence of the PUBSUB_EMULATOR_HOST environment variable upon instantiation. When this variable contains a host and port (such as localhost:8085), the SDK routes all publisher and subscriber calls to the local emulator, bypassing authentication requirements and remote API calls.

Adım Adım Çözüm

1
Identify the mechanism used by Google Cloud Client Libraries to detect local emulators.
Google Cloud Client Libraries for Pub/Sub check for specific host environment variables during initialization.
Emulators mimic GCP service endpoints locally so applications can run integration tests without internet access or GCP credentials.
2
Select the correct environment variable for the Cloud Pub/Sub emulator.
The standard variable name defined by GCP SDKs is PUBSUB_EMULATOR_HOST.
Defining PUBSUB_EMULATOR_HOST forces the client library to substitute production API endpoints with the specified local host and port.

Cevap: Configure Workload Identity Federation to authenticate external CI/CD pipeline runners using short-lived credentials, and grant the pipeline service account the Service Account User role (roles/iam.serviceAccountUser) only on specific deployment service accounts.; Store Terraform state files in a central Cloud Storage bucket with Object Versioning enabled and uniform bucket-level access enforced to manage infrastructure state safely.

Cevap

The correct recommendations are to configure Workload Identity Federation with fine-grained Service Account User permissions for external CI/CD runners, and to store Terraform state files in a Cloud Storage bucket configured with Object Versioning and uniform bucket-level access.
Configuring Workload Identity Federation allows external pipeline runners to authenticate securely without persistent service account keys, while restricting permissions to the Service Account User role on specific target accounts maintains least privilege. Additionally, using Cloud Storage with Object Versioning and uniform bucket-level access for Terraform remote state provides state locking, concurrency control, and resilience against state corruption.

Adım Adım Çözüm

1
Evaluate authentication and credential management for external CI/CD pipelines.
Identify that long-lived service account keys present security risks, whereas Workload Identity Federation provides secure short-lived token exchange.
Eliminating static service account keys enforces cloud security best practices.
2
Evaluate identity and access permissions for deployment execution.
Determine that assigning roles/iam.serviceAccountUser scoped to specific workload service accounts follows least privilege, whereas primitive roles like Editor grant dangerous, excessive access.
Least privilege access prevents unauthorized modifications to surrounding infrastructure.
3
Evaluate Infrastructure as Code (IaC) state management strategy.
Determine that Cloud Storage backends supporting locking, Object Versioning, and uniform access prevent race conditions and state corruption, whereas git repository state storage introduces corruption and credential leakage risks.
Centralized remote backends with locking are required for reliable, collaborative Terraform execution.

Cevap: Include an automated pre-flight step in the deployment pipeline that queries Google Cloud Quotas APIs to verify regional resource quotas prior to executing IaC provisioning.; Configure the IaC deployment pipeline to store state files in a remote Cloud Storage bucket with Object Versioning and state locking enabled.

Cevap

The correct validation practices are to include an automated pre-flight quota check against Google Cloud Quotas APIs prior to provisioning resources, and to store IaC state files in a remote Cloud Storage bucket with Object Versioning and state locking enabled.
Automating quota verification using Cloud Quotas APIs prevents deployment failures from unrequested quota limits, while using Cloud Storage with versioning and state locking protects IaC state integrity during testing runs.

Adım Adım Çözüm

1
Analyze deployment validation requirements for quota capacity and infrastructure state safety.
Identified the need to prevent resource allocation failures and avoid Terraform state corruption during automated testing.
Large-scale infrastructure updates fail at runtime if quota limits are exceeded or if concurrent pipeline runs overwrite unversioned local state.
2
Evaluate the practice of automated quota verification.
Querying Cloud Quotas APIs pre-flight ensures sufficient regional quota before initiating resource deployment.
Failing to request or verify quotas in advance leads to mid-deployment failures and incomplete provisioning.
3
Evaluate IaC state backend management.
Configuring Cloud Storage with Object Versioning and locking provides safe concurrent state management for automated validation workflows.
Local unversioned state files lead to concurrency lock failures and state corruption across CI/CD execution environments.
4
Evaluate security constraints around private GKE access and IAM role assignment.
Confirmed that disabling master authorized networks exposes private clusters, and assigning Service Account Admin grants excessive rights.
Private GKE cluster endpoints should be accessed via internal runners or proxy bastions, and pipelines only require the Service Account User role for identity impersonation.

Cevap: Define the Payment Processing Gateway Service Level Indicator (SLI) as the proportion of successful HTTP 2xx requests over total valid requests, and establish a high-stringency Service Level Objective (SLO) monitored via multi-window error budget burn-rate alerting.; Define the PDF Invoice Generator Service Level Indicator (SLI) based on task completion latency within an acceptable multi-hour window, establishing a relaxed Service Level Objective (SLO) with a generous error budget.

Cevap

The team should define the Payment Gateway SLI as the ratio of successful HTTP requests paired with a strict SLO using error budget burn-rate alerts, while defining the PDF Invoice Generator SLI based on asynchronous task latency with a relaxed SLO and generous error budget.
Aligning technical service levels with business objectives requires distinguishing between synchronous, revenue-critical transactions and asynchronous batch operations. For the payment gateway, measuring successful HTTP request ratios (SLI) and applying error budget burn-rate alerts ensures immediate detection of revenue loss without alerting on transient spikes. For the invoice generator, establishing a latency-based SLI with a relaxed SLO prevents over-engineering non-critical background processes.

Adım Adım Çözüm

1
Differentiate critical user-facing services from non-critical background workloads based on business impact.
Payment processing directly impacts revenue and requires strict availability goals, whereas batch invoice generation is asynchronous and tolerant to minor delays.
Business alignment requires spending engineering effort and tight error budgets only where customer friction or financial loss occurs.
2
Formulate appropriate Service Level Indicators (SLIs) for each service type.
Use successful HTTP request ratio for the synchronous payment API and completion latency over a multi-hour window for the asynchronous invoice generator.
SLIs must measure real user experience and functional satisfaction relevant to the workload type.
3
Implement error budget burn-rate alerting for high-priority services while setting relaxed targets for batch background services.
Prevents alert fatigue and over-engineering of non-critical components while preserving proactive alerting for revenue-critical paths.
Burn-rate alerting detects sustained budget consumption before severe outages occur.

Cevabı ve açıklamayı göster

Cevap: Deploy Cloud Run for stateless web services, Cloud SQL for regional relational storage, and configure VPC Service Controls around the resources to prevent unauthorized data exfiltration.

Cevap

The correct architecture deploys Cloud Run for stateless microservices, Cloud SQL for regional relational data, and VPC Service Controls to prevent data exfiltration.
The solution properly translates conceptual architectural tiering to physical GCP components: Cloud Run fits the stateless scale-to-zero HTTP web tier, Cloud SQL satisfies regional relational transaction requirements cost-effectively, and VPC Service Controls fulfills security isolation against exfiltration.

Adım Adım Çözüm

1
Map the compute requirement (stateless web services with scale-to-zero capability) to physical GCP services.
Cloud Run is selected over GKE because it provides serverless execution with auto-scaling to zero and minimum management overhead.
GKE introduces baseline node management costs and setup overhead for stateless services.
2
Map the storage requirement (regional relational database with SQL support) to physical GCP services.
Cloud SQL is selected over Cloud Spanner.
Cloud Spanner is designed for globally distributed database workloads, making it overly expensive and complex for single-region relational needs.
3
Map the network security requirement (preventing data exfiltration to outside resources).
VPC Service Controls is selected to establish a security perimeter.
IAM permissions alone cannot prevent data exfiltration by authorized users or compromised service accounts transferring data outside the boundary.

An enterprise digital advertising platform recently migrated its ad attribution engine to Google Cloud. A post-migration technical debt assessment reveals two primary architectural risks: infrastructure changes are executed using unversioned Terraform state files stored on individual developer workstations, and background worker service accounts remain assigned primitive Project Editor roles. Which TWO actions should the cloud architect recommend to effectively mitigate this technical debt? (Select TWO answers.)

Cevap: Configure a Cloud Storage remote backend with object versioning and state locking enabled for Terraform state management.; Replace the primitive Project Editor roles on service accounts with specific predefined IAM roles that grant minimal required permissions.

Cevap

The architect should migrate Terraform state files to a Cloud Storage remote backend with versioning and object locking, and replace primitive Project Editor IAM roles on service accounts with minimal predefined roles.
Establishing a remote Cloud Storage backend with object versioning and locking resolves IaC state vulnerability and concurrency issues. Replacing primitive Editor roles with fine-grained predefined roles removes excessive access and enforces least privilege governance.

Adım Adım Çözüm

1
Assess state management technical debt
Identified unversioned local state files as a major concurrency and corruption risk.
Centralizing state management in Cloud Storage with state locking guarantees consistent infrastructure provisioning across development teams.
2
Assess IAM technical debt
Identified over-privileged service accounts using Project Editor primitive roles.
Transitioning to narrow predefined roles aligns the environment with Google Cloud least-privilege security standards.

An enterprise security architect is transitioning an external CI/CD pipeline hosted on Azure DevOps from legacy static service account keys to short-lived federated credentials using Workload Identity Federation to securely access Secret Manager secrets.

In which sequential order should the architect execute the steps to configure this keyless authentication and authorization workflow?

Cevap

The correct sequence begins by creating the Workload Identity Pool and Provider, defining attribute mappings and conditions, assigning the workloadIdentityUser role to the external principal set on the target Service Account, granting the secretAccessor role to the Service Account on the secret, and finally executing the token exchange in the pipeline.
The sequence follows the logical dependency chain of Workload Identity Federation setup: first establishing trust via the Pool and Provider, defining mapped attribute conditions for security filtering, granting impersonation rights via workloadIdentityUser on the service account, granting least-privilege secret accessor permissions to the service account, and executing the client-side credential exchange.

Adım Adım Çözüm

1
Establish the federated trust anchor by creating a Workload Identity Pool and an OIDC Provider.
Google Cloud STS is configured to accept tokens issued by the external Azure DevOps issuer.
You must create the pool and provider infrastructure before referencing them in attribute rules or IAM policy bindings.
2
Define attribute mappings and assertion conditions on the provider.
Claims from the Azure DevOps JWT are mapped to GCP principal attributes (e.g., google.subject, attribute.repository).
Attribute mappings establish fine-grained identity filters so only authorized repositories or environments can authenticate.
3
Bind roles/iam.workloadIdentityUser on the target Service Account to the mapped principal set.
The external workload identity is authorized to impersonate the specific GCP Service Account.
Workload Identity Federation relies on the workloadIdentityUser role on the service account resource to authorize impersonation.
4
Grant roles/secretmanager.secretAccessor to the GCP Service Account on the secret.
The Service Account gains least-privilege read access to Secret Manager secret versions.
The service account itself must possess resource-level authorization to read secret payloads.
5
Update the pipeline script to call the GCP Security Token Service (STS) and IAM Credentials API.
The pipeline acquires a short-lived access token and fetches secret values dynamically.
Credential exchange and secret fetching can only succeed after all underlying IAM roles and trust relationships are provisioned.

An energy utility enterprise is modernizing its smart grid analytics platform hosted on Google Kubernetes Engine (GKE). The security team requires a software supply chain security model that guarantees only verified, signed container images from approved build pipelines can be deployed. Additionally, they require automated detection of newly published vulnerabilities for images already stored in Artifact Registry. Which TWO security configurations should the cloud architect implement to meet these requirements? (Select TWO.)

Cevap: Configure Binary Authorization on the GKE cluster with an attestation policy requiring cryptographic signatures generated during the CI/CD build process.; Enable continuous vulnerability scanning in Artifact Registry to automatically scan container images upon ingestion and monitor for newly disclosed vulnerabilities.

Cevap

The cloud architect should implement Binary Authorization on GKE with attestation policies to ensure container image supply chain integrity, and enable continuous vulnerability scanning in Artifact Registry to monitor stored images for newly published CVEs.
Binary Authorization enforces supply chain security by blocking un-attested container images at deployment time, while Artifact Registry continuous vulnerability scanning provides ongoing automated detection of newly discovered CVEs in stored container images.

Adım Adım Çözüm

1
Evaluate deploy-time image validation requirements
Identify Binary Authorization as the Google Cloud service designed to enforce attestation policies and block unverified container images from deploying onto GKE clusters.
Binary Authorization verifies cryptographic signatures created during CI/CD before deployment.
2
Evaluate image repository threat scanning requirements
Identify Artifact Registry continuous vulnerability scanning as the mechanism to scan images on push and continuously re-evaluate stored images as new CVE disclosures occur.
Continuous scanning provides automated, proactive discovery of vulnerabilities without requiring manual image rebuilds or re-scans.
3
Reject excessive privilege and perimeter exposure proposals
Discard options advocating primitive IAM role assignments or removing control plane authorized network restrictions on private GKE clusters.
Primitive IAM roles break principle of least privilege governance, and exposing GKE control plane endpoints introduces severe perimeter vulnerabilities.
