🚀 Deploying and Implementing a Cloud Solution - ACE Practice Questions

ACE Deploying & Implementing Question Bank (8 Questions)

Browse all 8 practice questions covering Deploying and Implementing a Cloud Solution for the ACE certification exam. Each question includes the full answer and a detailed explanation to help you understand the concepts.

1. Question 1Deploying and Implementing a Cloud Solution

   How do you create a GKE Autopilot cluster?

   Agcloud container clusters create my-cluster

   Bgcloud container clusters create-auto my-cluster --region=us-central1✓

   Cgcloud kubernetes create cluster

   Dkubectl create cluster
   Show Answer & Explanation

   Correct Answer: B

   Explanation:

   GKE Autopilot: gcloud container clusters create-auto NAME --region=REGION. Google manages nodes, scaling, security, networking. Pay per pod resource requests (not per node). Standard mode: gcloud container clusters create NAME (manage nodes yourself). Autopilot is recommended for most workloads.

2. Question 2Deploying and Implementing a Cloud Solution

   Which gcloud command creates a Compute Engine VM instance with a specific machine type in us-central1-a?

   Agcloud compute create-instance

   Bgcloud compute instances create my-vm --machine-type=e2-medium --zone=us-central1-a✓

   Cgcloud vm create

   Dgcloud instances new
   Show Answer & Explanation

   Correct Answer: B

   Explanation:

   gcloud compute instances create NAME --machine-type=TYPE --zone=ZONE. Common flags: --image-family, --image-project, --boot-disk-size, --boot-disk-type, --tags, --metadata, --service-account, --scopes, --subnet, --network. Use --preemptible or --provisioning-model=SPOT for cost savings.

3. Question 3Deploying and Implementing a Cloud Solution

   How do you deploy a container image to Cloud Run?

   Agcloud app deploy

   Bgcloud run deploy SERVICE --image=IMAGE_URL --region=REGION --allow-unauthenticated✓

   Ckubectl apply

   Dgcloud functions deploy
   Show Answer & Explanation

   Correct Answer: B

   Explanation:

   gcloud run deploy SERVICE --image=gcr.io/PROJECT/IMAGE:TAG --region=REGION. Key flags: --allow-unauthenticated (public), --port (container port), --memory, --cpu, --min-instances, --max-instances, --env-vars, --service-account. Cloud Run scales to zero by default.

4. Question 4Deploying and Implementing a Cloud Solution

   How do you deploy a Cloud Function triggered by HTTP requests?

   Agcloud run deploy

   Bgcloud functions deploy FUNCTION_NAME --gen2 --runtime=python312 --trigger-http --entry-point=main --region=REGION✓

   Cgcloud compute deploy

   Dkubectl deploy
   Show Answer & Explanation

   Correct Answer: B

   Explanation:

   gcloud functions deploy NAME --gen2 (2nd gen, recommended) --runtime=RUNTIME --trigger-http (or --trigger-topic, --trigger-bucket, --trigger-event-filters) --entry-point=FUNCTION. 2nd gen is built on Cloud Run — supports longer timeouts, concurrency, traffic splitting.

5. Question 5Ensuring Successful Operation of a Cloud Solution

   How do you perform a rolling update of a Deployment in GKE?

   ADelete all pods and recreate them

   BUpdate the container image using kubectl set image deployment/NAME CONTAINER=NEW_IMAGE or apply an updated YAML — Kubernetes handles the rolling update automatically✓

   CScale to zero then scale up

   DRestart the cluster
   Show Answer & Explanation

   Correct Answer: B

   Explanation:

   Rolling update: kubectl set image deployment/NAME CONTAINER=IMAGE:TAG or kubectl apply -f updated-deployment.yaml. Kubernetes gradually replaces old pods with new ones (maxSurge/maxUnavailable). Rollback: kubectl rollout undo deployment/NAME. Check status: kubectl rollout status deployment/NAME.

6. Question 6Configuring Access and Security

   A Compute Engine VM needs to access Cloud Storage but should not have access to BigQuery. How do you configure this?

   AUse the default service account with Editor role

   BCreate a custom service account, grant only roles/storage.objectViewer (or objectAdmin), and attach it to the VM✓

   CDisable the service account

   DUse API keys
   Show Answer & Explanation

   Correct Answer: B

   Explanation:

   Best practice: create dedicated service account per workload. Grant minimum required roles (roles/storage.objectViewer for read, objectAdmin for read+write). Attach to VM: --service-account=SA_EMAIL. Never use default service account in production (has Editor role). Avoid user-managed keys.

7. Question 7Deploying and Implementing a Cloud Solution

   Which command deploys an application to App Engine?

   Agcloud app deploy✓

   Bgcloud compute deploy

   Cgcloud run deploy

   Dgcloud functions deploy
   Show Answer & Explanation

   Correct Answer: A

   Explanation:

   'gcloud app deploy' deploys the application defined in app.yaml to App Engine, handling versioning, traffic splitting, and rollback capabilities.

8. Question 8Deploying and Implementing a Cloud Solution

   How do you deploy a containerized application to Cloud Run?

   AUpload source code only

   Bgcloud run deploy with a container image from Artifact Registry, or deploy from source code which builds automatically✓

   CSSH into a server and docker run

   DUse App Engine only
   Show Answer & Explanation

   Correct Answer: B

   Explanation:

   'gcloud run deploy SERVICE --image IMAGE' deploys a container. Cloud Run also supports source-based deployment (--source) which builds the container automatically using Cloud Build and Buildpacks.
