An automotive telematics enterprise needs to migrate 1.8 Petabytes of static binary log files and an active 4 TB MySQL transactional database from an on-premises data center to Google Cloud. The company has a 1 Gbps Dedicated Interconnect link available, but network policy caps migration bandwidth usage at 500 Mbps. The business mandates that the overall data transfer must complete within 30 days, and the transactional database cutover must incur minimal downtime. Which data transfer and migration strategy should a Cloud Architect recommend to meet these requirements?

Order multiple Google Cloud Transfer Appliance devices to perform an offline bulk migration of the 1.8 PB binary logs, and use Database Migration Service with continuous replication over the Dedicated Interconnect for the 4 TB MySQL database.

Configure Storage Transfer Service to stream both the 1.8 PB binary log files and database backups directly into Cloud Storage over the Dedicated Interconnect link.

Establish a high-throughput HA VPN tunnel over the public internet to migrate the 1.8 PB log files via gsutil parallel composite uploads while using Database Migration Service for the database.

Export both the 1.8 PB binary logs and a full mysqldump of the transactional database onto Transfer Appliance devices, then migrate the database to Cloud Spanner upon arrival to eliminate continuous online replication needs.

Cevabı ve açıklamayı göster

Cevap: Order multiple Google Cloud Transfer Appliance devices to perform an offline bulk migration of the 1.8 PB binary logs, and use Database Migration Service with continuous replication over the Dedicated Interconnect for the 4 TB MySQL database.

Cevap

The correct solution accurately separates the migration path based on data characteristics and constraints. Transferring 1.8 PB over a 500 Mbps network cap requires over 300 days. Using Transfer Appliance for offline transfer allows the 1.8 PB of binary logs to be securely ingested within the 30-day window. Meanwhile, the 4 TB active MySQL database can easily be transferred online over the Dedicated Interconnect link using Database Migration Service with continuous replication to achieve a near-zero downtime cutover.

Adım Adım Çözüm

Calculate network throughput capacity for the static dataset

Maximum network transfer rate =

500 \text{ Mbps} = 62.5 \text{ MB/s} \approx 5.4 \text{ TB/day}

. Transferring 1,800 TB over this link takes

\frac{1,800}{5.4} \approx 333 \text{ days}

, exceeding the 30-day limit.

Determines whether an online network transfer or offline physical appliance is required for the petabyte-scale static data.

Select the offline migration mechanism for unstructured binary logs

Deploy multiple Google Cloud Transfer Appliance units (e.g., 300 TB or 40 TB models) to ingest and physically ship the 1.8 PB dataset.

Transfer Appliance enables petabyte-scale data ingestion within days, adhering to the 30-day deadline without saturating network connections.

Select the online migration mechanism for the active MySQL transactional database

Use Database Migration Service (DMS) with continuous Change Data Capture (CDC) replication over the private Dedicated Interconnect.

A 4 TB database can easily sync over the 500 Mbps connection (

A genomics research institute is architecting a cloud-native pipeline on Google Cloud to process high-throughput DNA sequencing data. The architecture comprises two distinct workload requirements:

1. A high-performance computing (HPC) sequence alignment engine requiring custom Linux kernel drivers, message passing interface (MPI) inter-node communications with sub-millisecond network latency, and maximum I/O performance on local NVMe storage.
2. An edge-facing containerized API layer that receives large binary sequence data via continuous gRPC streams with individual session durations lasting up to 45 minutes, experiences unpredictable bursts, and must scale to zero instances during idle periods with zero infrastructure management overhead.

Which TWO compute platform choices and configurations should you implement to satisfy both workload requirements while maintaining architectural best practices? (Select TWO.)

Cevap: Provision Compute Engine virtual machines equipped with local NVMe SSDs, Tier 1 networking, gNIC interfaces, and configured within a compact placement policy for the sequence alignment engine.; Deploy the containerized web API layer on Cloud Run configured with HTTP/2 enabled, session affinity, and an extended request execution timeout of up to 60 minutes.

Cevap

The optimal architecture combines Compute Engine virtual machines configured with compact placement policies and local NVMe SSDs for the HPC alignment engine, alongside Cloud Run with HTTP/2 and extended timeouts for the containerized gRPC streaming API.

For specialized HPC workloads requiring custom Linux kernel modules, sub-millisecond MPI latency, and high-performance disk access, Compute Engine with compact placement policies, gNIC, and local NVMe SSDs is the only GCP compute platform that satisfies hardware and OS control constraints. For stateless or streaming containerized APIs requiring long timeouts (up to 60 minutes) and scale-to-zero functionality, Cloud Run provides full gRPC streaming support with zero server management overhead.

Adım Adım Çözüm

Analyze the HPC sequence alignment workload requirements

Identified requirements for custom OS kernel modules, low-latency inter-node MPI communication, and raw local I/O throughput.

Serverless and managed container platforms restrict host kernel access and do not support compact placement policies. Compute Engine VMs with compact placement policies and gNIC are required.

Analyze the containerized gRPC API workload requirements

Identified requirements for long-running gRPC streaming (up to 45 minutes), scale-to-zero capability, and minimal operational overhead.

Cloud Run supports containerized workloads, native HTTP/2 gRPC streaming, request timeouts up to 60 minutes, and automatic scale-to-zero without cluster management overhead.

Evaluate and reject misallocated compute platforms

Rejected GKE, App Engine Flexible, and Cloud Run for the HPC engine due to missing kernel/placement capabilities; rejected GKE for the API to avoid management overhead.

Matching workload operational profiles to the appropriate GCP compute abstraction optimizes performance while reducing baseline costs and operational complexity.

Cevap: Configure the Terraform remote backend using a Google Cloud Storage bucket with Object Versioning enabled for state persistence and native locking.; Submit regional quota increase requests for Compute Engine CPU cores and node pool resources prior to initiating automated large-scale provisioning.

Cevap

The correct practices are configuring a Cloud Storage remote backend with Object Versioning for Terraform state locking and requesting regional quota increases in advance before large-scale compute provisioning.

Centralizing Terraform state in a Cloud Storage bucket with Object Versioning and native locking prevents state corruption and concurrent state modifications. Additionally, requesting regional CPU and compute resource quota increases in advance ensures automated deployment scripts do not fail due to GCP quota limits during rapid cluster scale-outs.

Adım Adım Çözüm

Evaluate IaC state safety requirements.

Local state storage in ephemeral CI/CD environments causes state corruption and concurrency locks. Utilizing a GCS remote backend with Object Versioning provides central state persistence and state locking.

Safe team-based infrastructure provisioning requires centralized, versioned, and locked state management.

Evaluate resource capacity and quota constraints.

Automated deployments of large Compute Engine and GKE clusters frequently breach default regional quotas if not anticipated.

Requesting regional quota increases in advance guarantees that automated provisioning jobs complete cleanly without resource exhaustion errors.

Review security options against least privilege guidelines.

Primitive roles (`roles/owner`) and administrative permissions (`roles/iam.serviceAccountAdmin`) exceed required permissions for provisioning and operating compute workloads.

Workload service accounts should use granular predefined roles, and deployment service accounts require `roles/iam.serviceAccountUser` to attach service accounts to instances.

Cevap: Deploy the containerized application on Cloud Run.

Cevap

Deploying the containerized application on Cloud Run is the optimal architecture choice.

Cloud Run allows executing stateless containerized workloads over HTTP/HTTPS with automatic scaling down to zero when idle. This fulfills all constraints by eliminating baseline idle costs, accommodating unpredictable traffic spikes rapidly, and completely removing cluster and infrastructure management overhead.

Adım Adım Çözüm

Analyze workload state and protocol requirements.

The application is containerized, stateless, and handles incoming HTTPS webhooks.

Containerized HTTP workloads are well-suited for serverless container platforms or Kubernetes.

Evaluate operational overhead and scaling constraints.

Requirements mandate zero cluster management, rapid response to high traffic variance, and scale-to-zero capability.

Scale-to-zero eliminates idle billing during zero-traffic periods, while managed serverless eliminates node/cluster lifecycle maintenance.

Select the matching GCP compute platform.

Cloud Run provides serverless container execution with automatic scaling to zero, minimal operational overhead, and per-request billing.

GKE introduces unnecessary cluster abstraction (overkill), Compute Engine MIGs incur VM boot times and baseline VM costs, and App Engine Flexible cannot scale to zero instances.

Cevap: Define a log sink with a filter matching application logs with severity INFO or higher, and grant the sink's writer identity service account the Storage Object Creator role on the target Cloud Storage bucket.

Cevap

Configure a log sink filter that includes logs with severity INFO or higher to exclude debug entries, and assign the Storage Object Creator role (`roles/storage.objectCreator`) directly to the log sink's unique writer identity service account on the destination Cloud Storage bucket.

The correct approach configures an inclusion filter (`severity >= INFO`) on the log sink so that low-priority DEBUG logs are filtered out prior to export, reducing storage costs. It then grants the minimal required IAM role (`roles/storage.objectCreator`) specifically to the log sink's unique writer identity service account on the destination bucket, satisfying least-privilege security mandates.

Adım Adım Çözüm

Determine log filtering requirements.

Construct a log sink filter (e.g., `severity >= INFO`) to select operational logs while excluding DEBUG entries.

Filtering at the log sink prevents unnecessary log ingestion and storage overhead in the target sink destination.

Identify the writer identity of the log sink.

Obtain the unique service account email generated by Cloud Logging for the created sink (writerIdentity).

Cloud Logging exports logs using a dedicated service account identity per sink.

Apply least-privilege IAM permissions on the destination bucket.

Grant `roles/storage.objectCreator` to the writerIdentity on the target Cloud Storage bucket.

Cevap: Deploy the containerized service to fully managed Cloud Run to handle request-based scaling and zero-instance idle scale-down.; Configure concurrency settings on Cloud Run so each container instance processes multiple simultaneous requests.

Cevap

Deploying the microservice to fully managed Cloud Run and configuring container concurrency settings.

Deploying the application to fully managed Cloud Run provides a serverless environment that automatically scales up with HTTP traffic and down to zero instances when idle. Configuring container concurrency allows each instance to handle multiple simultaneous requests efficiently, lowering overall operational costs and management overhead.

Adım Adım Çözüm

Analyze the workload characteristics and operational constraints.

Identified a stateless, containerized HTTP microservice with bursty, unpredictable traffic, requiring zero-scaling and no infrastructure management.

Serverless platforms like Cloud Run are tailored specifically for stateless web services that need automatic scaling to zero.

Select the appropriate serverless compute platform.

Selected Cloud Run because it handles containerized HTTP workloads without requiring server provisioning or GKE cluster maintenance.

Cloud Run abstracts cluster management while automatically scaling based on incoming requests.

Configure platform scaling settings for efficiency.

Configured request concurrency per container instance to maximize throughput and resource utilization.

Concurrency allows a single container instance to process multiple requests simultaneously, reducing the total instance count needed during spikes.

A financial company is designing an operational observability strategy for a web application running on Compute Engine instances. To optimize Cloud Logging costs, the operations team must minimize the ingestion of high-volume verbose debug logs into the log bucket while ensuring that administrative security events trigger automated operational alerts in real time. Which TWO architectural and configuration actions should the team implement to meet these requirements? (Select TWO.)

Geçerli olan tümünü seçin

Configure an exclusion filter on the _Default log bucket to drop low-severity debug log entries prior to log ingestion.

Create a counter log-based metric filtered for administrative log events and attach a Cloud Monitoring alerting policy to that metric.

Assign the primitive Editor (roles/editor) role to the custom service account attached to the Compute Engine instances to allow metric writing.

Grant the Service Account Admin (roles/iam.serviceAccountAdmin) role to operations engineers so they can run Compute Engine instances under the application service account.

Add a log exclusion filter that drops all log entries with a severity of ERROR or higher to prevent log storage spikes.

Cevap: Configure an exclusion filter on the _Default log bucket to drop low-severity debug log entries prior to log ingestion.; Create a counter log-based metric filtered for administrative log events and attach a Cloud Monitoring alerting policy to that metric.

Cevap

The team should configure an exclusion filter on the _Default log bucket to drop low-severity debug logs and create a counter log-based metric for administrative events attached to a Cloud Monitoring alerting policy.

Configuring exclusion filters on the default log bucket prevents unwanted high-volume debug logs from being ingested into storage, effectively reducing costs. Additionally, creating a counter log-based metric for targeted administrative log events allows Cloud Monitoring to track log occurrences as time-series metrics and trigger automated alerts when thresholds are reached.

Adım Adım Çözüm

Configure log ingestion control to reduce Cloud Logging storage costs.

Applying an exclusion filter on the _Default log bucket drops high-volume debug logs before ingestion.

Exclusion filters prevent unneeded log entries from incurring storage and ingestion charges.

Set up real-time alerting based on specific log entry events.

Creating a counter log-based metric counts matching administrative entries, which Cloud Monitoring uses to trigger alerting policies.

Log-based metrics convert log data into time-series data suitable for standard operational alerting thresholds.

A cloud architect is preparing to provision a private Google Kubernetes Engine (GKE) cluster in GCP to host an internal microservice. Security governance mandates that node instances must not be publicly exposed and that principles of least privilege must be applied to node identity. Which of the following actions should be taken during cluster provisioning to satisfy these requirements? (Select TWO answers.)

Geçerli olan tümünü seçin

Provision the cluster with private nodes and enable Control Plane Authorized Networks to restrict access to management endpoints.

Assign a dedicated custom service account with minimal required roles to the cluster worker nodes instead of using the default Compute Engine service account.

Assign the primitive Editor role to the cluster node service account to ensure worker nodes can provision any needed GCP resource automatically.

Disable Control Plane Authorized Networks so that cluster administrators can access the master endpoint from any public IP without network restrictions.

Grant the Service Account Admin role to developers on the node service account so they can attach it when launching new node pools.

Cevabı ve açıklamayı göster

Cevap: Provision the cluster with private nodes and enable Control Plane Authorized Networks to restrict access to management endpoints.; Assign a dedicated custom service account with minimal required roles to the cluster worker nodes instead of using the default Compute Engine service account.

Cevap

Provisioning private cluster nodes combined with Control Plane Authorized Networks ensures network isolation, while assigning a dedicated custom service account with minimal IAM permissions guarantees identity isolation.

Provisioning private nodes alongside Control Plane Authorized Networks ensures node instances have no public IPs and control plane access is restricted. Configuring a custom service account with minimal roles enforces least privilege for workload credentials on cluster nodes.

Adım Adım Çözüm

Identify network isolation requirements for the GKE cluster.

Creating a private cluster ensures worker nodes receive only internal IP addresses, while enabling Control Plane Authorized Networks limits master endpoint access to authorized source CIDRs.

Prevents unauthorized internet access to cluster nodes and master endpoints.

Identify least-privilege IAM identity requirements for cluster nodes.

Worker nodes should run under a dedicated custom service account configured with minimal required IAM roles.

Avoids using the default Compute Engine service account which has broad access rights.
