Google Cloud Certified - Professional Cloud DevOps Engineer Exam Questions and Answers

Question 25

You support a production service that runs on a single Compute Engine instance. You regularly need to spend time on recreating the service by deleting the crashing instance and creating a new instance based on the relevant image. You want to reduce the time spent performing manual operations while following Site Reliability Engineering principles. What should you do?

Options:

A.

File a bug with the development team so they can find the root cause of the crashing instance.

B.

Create a Managed Instance Group with a single instance and use health checks to determine the system status.

C.

Add a Load Balancer in front of the Compute Engine instance and use health checks to determine the system status.

D.

Create a Stackdriver Monitoring dashboard with SMS alerts to be able to start recreating the crashed instance promptly after it has crashed.

Question 26

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

Options:

A.

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

Question 27

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?

Options:

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.

Question 28

You encounter a large number of outages in the production systems you support. You receive alerts for all the outages that wake you up at night. The alerts are due to unhealthy systems that are automatically restarted within a minute. You want to set up a process that would prevent staff burnout while following Site Reliability Engineering practices. What should you do?

Options:

A.

Eliminate unactionable alerts.

B.

Create an incident report for each of the alerts.

C.

Distribute the alerts to engineers in different time zones.

D.

Redefine the related Service Level Objective so that the error budget is not exhausted.
