Your organization uses a Shared VPC to centrally manage network resources. A project that is not the host project needs to create a Cloud SQL instance using a private IP in the Shared VPC. What must be configured?

A.Create a VPC peering between the service project and the host project
B.Grant the service project the 'compute.networkUser' role on the VPC network
C.Use Cloud NAT to allow the Cloud SQL instance to communicate
D.Enable the Service Networking API and allocate an IP range for the Cloud SQL instance
AnswerD

Correct. Private services access requires allocating an IP range and establishing a connection.

Why this answer

For a service project to allocate private IP in a Shared VPC, the Shared VPC host project must grant the service project the 'compute.networkUser' role on the subnetwork. Additionally, the service project needs the Service Networking API enabled and a private service access connection.

A company wants to grant a service account in Project A the ability to push containers to Artifact Registry in Project B. They want to follow the principle of least privilege. Which IAM roles should they assign?

A.Grant the service account the Storage Object Admin role (roles/storage.objectAdmin) on Project B
B.Grant the service account the Artifact Registry Writer role (roles/artifactregistry.writer) on the repository in Project B
C.Grant the service account the Artifact Registry Admin role (roles/artifactregistry.admin) on the repository in Project B
D.Grant the service account the Artifact Registry Reader role (roles/artifactregistry.reader) on the repository in Project B
AnswerB

Writer role allows pushing images and is the correct least-privilege role for this task.

Why this answer

To push containers, the service account needs the Artifact Registry Writer role (roles/artifactregistry.writer) on the repository in Project B. The Storage Object Admin role is too broad. The Artifact Registry Admin role is overly permissive.

The Viewer role only allows reading.

An organization runs a stateful application on GKE that must not lose data during cluster upgrades or node repairs. The application uses persistent volumes with ReadWriteOnce access mode. The team wants to ensure pods are not evicted simultaneously. Which Kubernetes resource should they configure?

A.PodDisruptionBudget
B.ClusterAutoscaler
C.HorizontalPodAutoscaler
D.VerticalPodAutoscaler
AnswerA

A PodDisruptionBudget (PDB) specifies the minimum number or percentage of replicas that must remain available during voluntary disruptions, such as cluster upgrades or node repairs. By setting `maxUnavailable: 0` or `minAvailable: 1`, the PDB prevents the simultaneous eviction of pods using ReadWriteOnce persistent volumes, thereby satisfying the requirement that no data be lost and pods are not evicted concurrently.

Why this answer

PodDisruptionBudget (PDB) specifies the minimum number of available pods that must remain up during voluntary disruptions, such as node upgrades.

A team is deploying a microservice on Cloud Run that needs to access a Cloud SQL database securely. They want to avoid using public IPs and ensure traffic stays within Google's network. Which configuration should they use?

A.Configure Cloud SQL with a public IP and use Cloud SQL Proxy in the Cloud Run service
B.Enable Private Google Access on the VPC subnet
C.Use Serverless VPC Access and assign a private IP to the Cloud SQL instance
D.Create a VPC network peering between the Cloud Run tenant project and the Cloud SQL project
AnswerC

Serverless VPC Access connects Cloud Run to your VPC, and Cloud SQL private IP ensures traffic stays within Google's network.

Why this answer

Serverless VPC Access allows Cloud Run to connect to a VPC network via a VPC connector. Combined with Private Services Access, Cloud SQL can be configured with a private IP (within the VPC) and accessed without traversing the public internet. Cloud SQL Proxy is a sidecar pattern that can use public IP with SSL, but it does not keep traffic entirely within Google's network if the Cloud SQL instance uses a public IP.

Private Google Access is for on-premises or VM access to Google APIs, not for Cloud Run to Cloud SQL.

A financial services company requires that all audit logs be retained for 7 years in a cost-effective, immutable storage. They also need to run ad-hoc SQL queries on the logs. Which configuration should they use?

A.Create a log sink to BigQuery with a 7-year partition expiration and use BigQuery's SQL capabilities
B.Use Cloud Logging's default retention and set up a log-based metric to trigger a Cloud Function that copies logs to BigQuery
C.Export logs to Cloud Storage with a retention policy set to 7 years and use Cloud Storage SQL interface
D.Create two log sinks: one to BigQuery for querying, and one to Cloud Storage with object retention policy for immutable storage
AnswerD

Log sinks to BigQuery allow SQL queries; Cloud Storage with retention policy provides immutable, cost-effective long-term storage.

Why this answer

Logging can export logs to BigQuery for SQL querying, and BigQuery offers time-based partitioning and long-term retention. However, for immutable storage, Cloud Storage with retention policy is recommended. The best approach is to use a log sink to BigQuery for analysis, and another sink to Cloud Storage with a retention policy for long-term immutable storage.

Option D combines both sinks correctly.

A company has a legacy application that runs on a single Compute Engine VM and expects to use a fixed IP address. They want to migrate the VM to a different region with minimal downtime. Which TWO actions should they take?

Select 2 answers
A.Use gcloud compute instances move command
B.Delete the original VM before creating the new one
C.Convert the VM to a managed instance group
D.Reserve a static external IP address in the target region
E.Create a snapshot of the boot disk and create a new VM from the snapshot in the target region
AnswersD, E

Reserving a static IP ensures the VM has a fixed IP after migration.

Why this answer

Snapshot the VM disk and create a new VM from the snapshot in the target region. Reserve a static external IP address in the target region to keep the IP fixed. Snapshots are regional, so you can create an instance in another region.

Deleting the original VM first would cause downtime. Converting to managed instance group is not necessary for a single VM.

A GKE cluster has a Horizontal Pod Autoscaler (HPA) configured for CPU utilization. The pods are not scaling up even though CPU usage is high. What could be the reason?

A.The cluster autoscaler is disabled
B.The HPA is configured with the wrong metric name
C.The node pool is out of capacity
D.The pods do not have resource requests defined
AnswerD

HPA requires CPU resource requests on pods to calculate utilization.

Why this answer

The HPA may not have permissions to read metrics or the metrics server might be unavailable. Also, the target CPU utilization might be set incorrectly. Another common issue is that the HPA is using the wrong metric or the pod resource requests are not set.

An engineer needs to share a VPC network across multiple projects in an organization while maintaining centralized network administration. Which approach should they use?

A.Shared VPC
B.VPC peering between all projects
C.Private Google Access
D.Cloud VPN between projects
AnswerA

Shared VPC allows a host project to share networks with multiple service projects.

Why this answer

Shared VPC allows a host project to share its VPC network with service projects, enabling centralized network administration. VPC peering connects separate VPCs but does not allow centralized administration.

An organization wants to ensure that all VMs in a project have the 'restricted-vm' tag to apply a firewall rule that allows only SSH from a bastion host. The VMs are created by multiple teams. Which approach ensures the tag is automatically applied to all new VMs?

A.Create a Cloud Function that listens to Compute Engine audit logs and adds the tag to new instances
B.Use a custom image that includes the tag in the instance metadata
C.Use an organization policy to require the tag
D.Configure OS Config with a software recipe to add the tag
AnswerA

This approach can tag instances automatically upon creation by monitoring the compute.instances.insert operation.

Why this answer

OS Config can enforce OS policies, but tagging is done via instance templates or organization policies. Using a custom image with the tag is not automatic. A pre-create Cloud Function can detect VM creation and add the tag.

Org policies cannot enforce tags directly.

A developer wants to deploy a containerized web application on Google Cloud that can scale to zero when not in use and charges only for resources consumed during request processing. Which compute service should they choose?

A.Cloud Run
B.Google Kubernetes Engine (GKE)
C.App Engine Flexible Environment
D.Compute Engine instance group
AnswerA

Cloud Run is serverless and can scale to zero, charging only for resources used during request processing. It is ideal for intermittent containerized workloads.

Why this answer

Cloud Run is a serverless container platform that scales to zero when idle and charges per request, making it cost-effective for intermittent traffic. GKE requires at least one node to be running, so it cannot scale to zero. Compute Engine instances incur costs even when idle.

App Engine Flexible Environment also runs at least one instance.

A Cloud Run service needs to connect to a Cloud SQL MySQL instance privately without using public IP. What must be configured?

A.Set up VPC Network Peering between Cloud Run and Cloud SQL
B.Enable Private Google Access on the VPC subnet
C.Use Cloud SQL Proxy as a sidecar container
D.Deploy a VPC connector and attach it to the Cloud Run service
AnswerD

The VPC connector enables Cloud Run to send traffic to internal IP addresses in the VPC, such as Cloud SQL private IP.

Why this answer

To privately connect Cloud Run to Cloud SQL, you need a Serverless VPC Access connector in the same VPC as the Cloud SQL instance, and then use the private IP of Cloud SQL. Private Google Access is for on-prem, not Cloud Run. Direct VPC is not available for Cloud Run.

A team is running a GKE cluster with a workload that has variable CPU and memory usage. They want to automatically adjust pod resource requests and limits based on historical usage to improve resource efficiency. Which feature should they use?

A.Vertical Pod Autoscaler (VPA)
B.PodDisruptionBudget (PDB)
C.Horizontal Pod Autoscaler (HPA)
D.Cluster Autoscaler
AnswerA

VPA adjusts CPU and memory requests/limits based on usage, improving resource efficiency.

Why this answer

Vertical Pod Autoscaler (VPA) automatically adjusts CPU and memory requests and limits of pods based on historical usage, making it ideal for right-sizing. Horizontal Pod Autoscaler (HPA) scales the number of pods based on metrics, but does not modify resource requests. Cluster Autoscaler adjusts the number of nodes.

PodDisruptionBudget controls pod disruptions during maintenance.

An organization wants to manage DNS records for a domain they own (e.g., example.com) and use Google Cloud for authoritative DNS. They also need to resolve internal hostnames for resources within their VPC. Which Cloud DNS configuration should they use?

A.Create a single public managed zone and use DNS peering for internal resolution
B.Create a single private managed zone for both external and internal DNS resolution
C.Use Google Groups DNS to manage both public and private records
D.Create a public managed zone for example.com and a private managed zone for internal VPC resources
AnswerD

Public zone handles external DNS queries; private zone attached to the VPC handles internal resolution.

Why this answer

Cloud DNS public zones manage public DNS records for internet-facing domains. Cloud DNS private zones are used for internal DNS resolution within VPCs. The correct approach is to create a public zone for example.com and a private zone for internal hostnames attached to the VPC.

A startup wants to store application secrets (e.g., API keys, database passwords) securely on Google Cloud. They need to support automatic rotation of secrets and fine-grained access control. Which TWO services should they use? (Choose 2.)

Select 2 answers
A.Cloud Storage with object versioning
B.Cloud Functions
C.Secret Manager
D.Cloud Identity and Access Management (IAM)
E.Cloud Key Management Service (Cloud KMS)
AnswersC, E

Secret Manager is the dedicated service for storing and managing secrets with rotation and versioning.

Why this answer

Secret Manager is the primary service for storing secrets, with support for versioning, automatic rotation, and IAM. Cloud KMS can be used to encrypt secrets stored in Secret Manager, providing an additional layer of security. Cloud Key Management Service (KMS) is used for managing encryption keys, but Secret Manager already encrypts secrets at rest using Google-managed keys by default; using CMEK via Cloud KMS adds customer-managed key control.

Cloud Storage is not designed for secrets. IAM alone does not provide secret storage. Cloud Functions can access secrets but is not a storage service.

A company runs a batch processing workload on Compute Engine instances that read from Cloud Storage and write results to BigQuery. The instances are launched via a managed instance group (MIG) and each job takes about 30 minutes. The company wants to reduce costs without sacrificing performance. What is the most cost-effective way to provision these instances?

A.Use sole-tenant nodes
B.Use standard (on-demand) VMs
C.Use preemptible VMs
D.Use committed use discounts (CUDs) with 1-year commitment
AnswerC

Preemptible VMs provide significant cost savings for fault-tolerant batch jobs.

Why this answer

Preemptible VMs are up to 80% cheaper than regular VMs and are ideal for batch workloads that can tolerate interruptions. The job can be designed to checkpoint progress and restart on a new VM if preempted. Regular VMs are more expensive, sole-tenant nodes are for isolation requirements, and CUDs offer discounts for committed use but may not be as cost-effective for short-lived batch jobs.

A team is using Cloud Build to deploy a microservice to Cloud Run. They want to ensure that only containers built from a specific trusted branch in their source repository are deployed to production. Which Cloud Build feature should they use?

A.Binary Authorization attestors
B.Cloud Build trigger branch filtering
C.Cloud Deploy delivery pipeline approvals
D.Artifact Registry IAM permissions
AnswerB

Cloud Build triggers can be scoped to specific branches using regex, ensuring only trusted branches trigger builds.

Why this answer

Cloud Build triggers can be configured to respond only to specific branches (e.g., 'main' or 'release/*'). By setting the trigger's included files filter and branch regex, they can restrict builds to that branch. Artifact Registry controls access to container images, but does not restrict deployment by branch.

Cloud Deploy is a separate service for progressive delivery. Binary Authorization enforces policies at deployment time but does not filter by branch.

A company has a Cloud Run service that processes high-throughput requests. They want to reduce latency by keeping a baseline of warm instances always ready to handle traffic. Which Cloud Run configuration parameters should they adjust?

A.Set min-instances to 0 and max-instances to 100
B.Set max-instances to a high value and concurrency to 1
C.Set min-instances to 10 and CPU to always-on
D.Set max-instances to 0 (unlimited) and concurrency to 80
AnswerC

Min-instances ensures 10 warm instances are always ready, and CPU always-on reduces latency by keeping CPU allocated even when not serving requests.

Why this answer

Setting min-instances to a value greater than 0 ensures that Cloud Run keeps at least that many instances warm, ready to serve requests without cold start latency. Max-instances sets an upper limit. Concurrency controls how many requests each instance can handle.

CPU allocation can be set to always-on to reduce latency, but that is a separate setting.

A company uses Cloud Build to deploy a Java application to Artifact Registry. They want to automatically trigger a build only when changes are pushed to the 'main' branch in their Cloud Source Repository. Which configuration should they use?

A.Configure a Cloud Function that listens for Pub/Sub messages from Cloud Source Repo and calls Cloud Build API
B.Create a Cloud Build trigger with an included branch filter set to '^main$'
C.Create a Cloud Scheduler job that runs a Pub/Sub push to Cloud Build every hour
D.Use a Cloud Build build step that checks the branch name and aborts if not main
AnswerB

The branch filter '^main$' ensures only pushes to the main branch trigger a build.

Why this answer

Cloud Build triggers can be configured with a branch filter (regex) to trigger builds only on specific branches. The trigger is set to watch the repository and fire on push events matching the branch pattern. Using a Cloud Scheduler with Pub/Sub is an alternative for scheduled builds, but not for push-based triggers.

You have a Cloud Deploy delivery pipeline with an approval gate. You want to automatically roll back a release if the rollout fails during the deploy step. How should you configure the pipeline?

A.Set an automatic rollback policy in the delivery pipeline definition
B.Use a Cloud Build post-deploy hook to check the rollout status and roll back if needed
C.Configure the approval gate to reject the deployment if it fails
D.Enable the 'rollback on failure' flag in the pipeline
AnswerA

Correct. The delivery pipeline definition supports a `rollback_policy` that automatically rolls back on deploy failure.

Why this answer

Cloud Deploy does have a built-in automatic rollback feature via the `rollback_policy` in the delivery pipeline definition. Setting this policy automatically rolls back a release if the rollout fails during the deploy step. Option B describes a custom solution that is unnecessary because the native policy exists.

Option C is incorrect because approval gates are for manual approval and cannot automatically trigger a rollback. Option D is incorrect because no such global flag exists. Therefore, option A is correct.

Exam trap

Candidates may assume Cloud Deploy lacks automated rollback, but it actually supports it via a pipeline-level rollback policy.

A company runs a stateful application on GKE that requires persistent storage. They want to ensure that during cluster upgrades, pods are not disrupted and storage is preserved. Which configuration should they use?

A.Enable Cluster Autoscaler on the node pool
B.Use a Deployment with a HorizontalPodAutoscaler
C.Use a StatefulSet with a PodDisruptionBudget
D.Use PersistentVolumeClaims with ReadWriteMany access mode
AnswerC

StatefulSets provide stable persistent storage for each pod, and PodDisruptionBudgets prevent voluntary disruptions during cluster upgrades.

Why this answer

PodDisruptionBudgets (PDBs) ensure that a minimum number of pods remain available during voluntary disruptions like cluster upgrades. PersistentVolumeClaims with ReadWriteOnce access mode allow pods to persist data. Combining PDBs with StatefulSets provides ordered, graceful deployment and scaling while preserving storage.

The cluster autoscaler only adjusts node count, not pod disruptions. HorizontalPodAutoscaler scales pods based on metrics but does not protect against disruptions.

B.Configure a PodDisruptionBudget for the deployment
C.Create a multi-zonal node pool to spread nodes across multiple zones
D.Use a HorizontalPodAutoscaler with high target utilization
E.Enable Cluster Autoscaler on the node pool
AnswersB, C

PDB ensures that voluntary disruptions (e.g., upgrades) do not bring all pods down.

Why this answer

PodDisruptionBudgets (PDBs) ensure that a minimum number of pods remain available during voluntary disruptions like node upgrades. Multi-zonal node pools distribute pods across zones, protecting against zone failures. Cluster Autoscaler adds nodes when needed but does not directly ensure availability.

HPA scales pods but does not handle disruptions. Workload Identity is for authentication, not availability.

A.To automatically scale pods based on CPU usage
B.To distribute pods across different zones
C.To ensure a minimum number of pods are always available during voluntary disruptions
D.To prevent any pod from being terminated

A team uses Cloud Functions triggered by Cloud Storage events to process uploaded images. They want to ensure that only HTTP-triggered functions can be invoked from outside the project. Which configuration should they apply?

A.Add a VPC firewall rule to allow only internal traffic
B.Set --ingress-settings=internal-only on the HTTP function
C.Remove the Cloud Storage trigger function's trigger
D.Set --ingress-settings=all on the HTTP function
AnswerB

This restricts invocation to within the project.

Why this answer

For Cloud Functions (1st gen), setting --ingress-settings=internal-only restricts invocation to within the project. For Cloud Functions (2nd gen), using an ingress setting of 'all' allows external invocation; using 'internal-only' blocks external calls.

A security team wants to enforce that only container images signed by their internal CI/CD pipeline can run on GKE clusters. They also need to ensure that unsigned images are rejected at admission time. Which combination of services and configurations should they use?

A.GKE PodSecurityPolicy with allowed registries
B.Binary Authorization with Cloud KMS for signing
C.Cloud Build with Container Analysis
D.Artifact Registry vulnerability scanning and IAM roles
AnswerB

Binary Authorization enforces policy that only signed images can run. Cloud KMS provides the cryptographic keys for signing.

Why this answer

Binary Authorization enforces policy by requiring images to be signed by trusted signers (e.g., using Cloud KMS). It integrates with GKE admission control to block unsigned images. Cloud KMS creates and manages signing keys.

Artifact Registry stores signed images but does not enforce policy. Cloud Build can be used to sign images during build, but the enforcement mechanism is Binary Authorization.

A.Build steps in cloudbuild.yaml
B.Build triggers with included files filter
C.Cloud Build's 'includedFiles' option in the build configuration
D.Artifact Registry triggers
AnswerB

Correct: Cloud Build triggers can filter by file paths to trigger builds only on changes to specific directories.

B.Use a Deployment with a PodDisruptionBudget set to maxUnavailable=0
C.Deploy a Deployment with a nodeSelector for one zone
D.Use a DaemonSet with node affinity
AnswerA

StatefulSet provides stable storage and network identity; anti-affinity ensures one pod per node; regional cluster spreads nodes across zones.

Why this answer

A StatefulSet with pod anti-affinity required ensures one pod per node. A regional cluster with nodes in multiple zones allows rescheduling in another zone. A single-zone cluster would not survive a zonal failure.

A.Cloud Build and Cloud Run
B.Artifact Registry and GKE alone
C.Cloud Source Repositories and Compute Engine
D.Cloud Build and Cloud Deploy
AnswerD

Correct: Cloud Build builds and pushes the image, Cloud Deploy handles deployment to GKE.

Why this answer

Cloud Build can build the Docker image and push it to Artifact Registry. Cloud Deploy can then deploy the image to GKE using a delivery pipeline. Cloud Run is for serverless containers, not GKE.

Cloud Source Repositories is a code repository, not a deployment service. Compute Engine is not needed for this use case.
