Google PCA Managing Implementation and Ensuring Solution and Operations Reliability Practice Test 6 — 15 Questions

Question 1

A company uses GKE with Istio for service mesh. They want to implement a canary deployment for a critical service with fine-grained traffic splitting. Which THREE components should they configure? (Choose three.)

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Kubernetes Service. Istio uses VirtualService, DestinationRule, and Kubernetes Service to achieve canary deployments. VirtualService defines traffic routing rules, DestinationRule defines subsets (versions), and Kubernetes Service serves as a stable endpoint. Ingress Gateway is for external traffic, not internal. HorizontalPodAutoscaler is for scaling, not routing.

Answer

Ingress Gateway

Answer

HorizontalPodAutoscaler

Question 2

An organization wants to connect its on-premises data center to Google Cloud with a consistent 10 Gbps bandwidth and a 99.99% availability SLA. They already have a Dedicated Interconnect connection, but need to ensure high availability. What should they do?

Question 3

A company uses Cloud SQL for MySQL for its transactional database. They need to ensure automatic failover in case of a zonal outage with minimal data loss. What configuration should they use?

Question 4

An e-commerce platform uses Cloud Spanner in a multi-region configuration. They want to achieve the highest possible availability SLA. Which deployment configuration should they choose?

Question 5

A DevOps team wants to monitor custom application metrics and set up an alert that triggers when the error rate exceeds 1% over a 5-minute window. Which Cloud Monitoring features should they use?

Question 6

After a production incident, a team wants to conduct a postmortem to identify root causes and document actions to prevent recurrence. Which steps are part of Google's recommended postmortem process?

Question 7

A company uses Cloud SQL for PostgreSQL and needs to recover a database to a specific point in time within the last week, down to the second. Which feature should they enable?

Question 8

A team needs to run load tests against their application deployed on GKE to validate performance under peak traffic. They want to simulate 100,000 concurrent users generating HTTP requests. Which tool should they use?

Question 9

An organization wants to implement a canary deployment in GKE, directing 5% of traffic to a new version and 95% to the stable version. They want to use Google Cloud's managed service mesh for traffic splitting. Which approach should they use?

Question 10

An engineer needs to view the logs of a specific Compute Engine instance in near real-time from the command line. Which gcloud command should they use?

Question 11

A company wants to set up automated failover between two on-premises data centers and Google Cloud using Cloud VPN. They require a 99.99% SLA for the VPN connection. What configuration should they use?

Question 12

A financial services company uses Cloud Storage to store sensitive transaction records. They need to ensure that objects cannot be deleted or overwritten for a retention period of 7 years, even by the bucket owner. Which feature should they enable?

Question 13

A company wants to back up their GKE cluster's etcd data and persistent volumes for disaster recovery. They are evaluating Velero. Which two components does Velero require to perform backups? (Choose two.)

Accepted Answer

A Cloud Storage bucket for backup storage. Velero requires two core components: a storage destination (like a Cloud Storage bucket) to store backup artifacts, and a service account with appropriate IAM permissions to authenticate with the Google Cloud APIs and access cluster resources. A kubeconfig file is used for client-side kubectl operations, not as a component for Velero backups. Velero uses its own service account to communicate with the Kubernetes API server and trigger volume snapshots. Therefore, only option D is correct; option E is incorrect because Velero does not require a kubeconfig file.

Answer

A separate database such as Cloud SQL

Answer

A Velero plugin for each persistent volume

Answer

A dedicated backup server with stateful storage

Answer

Access to the cluster's kubeconfig file

Question 14

An organization wants to implement a change management strategy for a microservices application on GKE, allowing gradual rollouts and immediate rollback if issues arise. Which three practices should they adopt? (Choose three.)

Question 15

A team needs to set up alerting for a production service. They want to receive notifications when the 99th percentile latency exceeds 500ms for 5 minutes. Which two Cloud Monitoring components are required? (Choose two.)
