Question 11

You need to run a business-critical workload on a fixed set of Compute Engine instances for several months. The workload is stable with the exact amount of resources allocated to it. You want to lower the costs for this workload without any performance implications. What should you do?

A. Purchase Committed Use Discounts.
B. Migrate the instances to a Managed Instance Group.
C. Convert the instances to preemptible virtual machines.
D. Create an Unmanaged Instance Group for the instances used to run the workload.

Correct Answer:A

Question 12

You need to define Service Level Objectives (SLOs) for a high-traffic multi-region web application. Customers expect the application to always be available and have fast response times. Customers are currently happy with the application performance and availability. Based on current measurement, you observe that the 90th percentile of latency is 120ms and the 95th percentile of latency is 275ms over a 28-day window. What latency SLO would you recommend to the team to publish?

A. 90th percentile – 100ms 95th percentile – 250ms
B. 90th percentile – 120ms 95th percentile – 275ms
C. 90th percentile – 150ms 95th percentile – 300ms
D. 90th percentile – 250ms 95th percentile – 400ms

Question 13

You support a high-traffic web application that runs on Google Cloud Platform (GCP). You need to measure application reliability from a user perspective without making any engineering changes to it. What should you do?
Choose 2 answers

A. Review current application metrics and add new ones as needed.
B. Modify the code to capture additional information for user interaction.
C. Analyze the web proxy logs only and capture response time of each request.
D. Create new synthetic clients to simulate a user journey using the application.
E. Use current and historic Request Logs to trace customer interaction with the application.

Question 14

You are deploying an application that needs to access sensitive information. You need to ensure that this information is encrypted and the risk of exposure is minimal if a breach occurs. What should you do?

A. Store the encryption keys in Cloud Key Management Service (KMS) and rotate the keys frequently
B. Inject the secret at the time of instance creation via an encrypted configuration management system.
C. Integrate the application with a Single sign-on (SSO) system and do not expose secrets to the application
D. Leverage a continuous build pipeline that produces multiple versions of the secret for each instance of the application.

Question 15

You support a multi-region web service running on Google Kubernetes Engine (GKE) behind a Global HTTP'S Cloud Load Balancer (CLB). For legacy reasons, user requests first go through a third-party Content Delivery Network (CDN). which then routes traffic to the CLB. You have already implemented an availability Service Level Indicator (SLI) at the CLB level. However, you want to increase coverage in case of a potential load balancer misconfiguration. CDN failure, or other global networking catastrophe. Where should you measure this new SLI?
Choose 2 answers

A. Your application servers' logs
B. Instrumentation coded directly in the client
C. Metrics exported from the application servers
D. GKE health checks for your application servers
E. A synthetic client that periodically sends simulated user requests

Correct Answer:BE
