• Question 112:

  Your product is currently deployed in three Google Cloud Platform (GCP) zones with your users divided between the zones. You can fail over from one zone to another, but it causes a 10-minute service disruption for the affected users. You typically experience a database failure once per quarter and can detect it within five minutes. You are cataloging the reliability risks of a new real-time chat feature for your product. You catalog the following information for each risk: Mean Time to Detect (MTTD) in minutes Mean Time to Repair (MTTR) in minutes Mean Time Between Failure (MTBF) in days User Impact Percentage

  The chat feature requires a new database system that takes twice as long to successfully fail over between zones. You want to account for the risk of the new database failing in one zone. What would be the values for the risk of database failover with the new system?

  A. MTTD: 5 MTTR: 10 MTBF: 90 Impact: 33%
  B. MTTD: 5 MTTR: 20 MTBF: 90 Impact: 33%
  C. MTTD: 5 MTTR: 10 MTBF: 90 Impact: 50%
  D. MTTD: 5 MTTR: 20 MTBF: 90 Impact: 50%
  B. MTTD: 5 MTTR: 20 MTBF: 90 Impact: 33%

  D. Pre-provision the additional compute power that was used last season, and expect growth.
  D. Pre-provision the additional compute power that was used last season, and expect growth.

• Question 114:

  You are using Terraform to manage infrastructure as code within a CI/CD pipeline. You notice that multiple copies of the entire infrastructure stack exist in your Google Cloud project, and a new copy is created each time a change to the existing infrastructure is made. You need to optimize your cloud spend by ensuring that only a single instance of your infrastructure stack exists at a time. You want to follow Google-recommended practices. What should you do?

  A. Create a new pipeline to delete old infrastructure stacks when they are no longer needed.
  B. Confirm that the pipeline is storing and retrieving the terraform.tfstate file from Cloud Storage with the Terraform gcs backend.
  C. Verify that the pipeline is storing and retrieving the terraform.tfstate file from a source control.
  D. Update the pipeline to remove any existing infrastructure before you apply the latest configuration.
  D. Update the pipeline to remove any existing infrastructure before you apply the latest configuration.

• Question 115:

  Your company wants to implement a CD pipeline in Cloud Deploy for a web service deployed to GKE. The web service currently does not have any automated testing. The Quality Assurance team must manually verify any new releases of the web service before any production traffic is processed. You need to design the CD pipeline. What should you do?

  A. Create two pipeline stages, and use a canary deployment strategy.
  B. Create a single pipeline stage, and use a standard deployment strategy.
  C. Create a single pipeline stage, and use a canary deployment strategy.
  D. Create two pipeline stages, and use a standard deployment strategy.
  D. Create two pipeline stages, and use a standard deployment strategy.

• Question 116:

  Your application runs on Google Cloud Platform (GCP). You need to implement Jenkins for deploying application releases to GCP. You want to streamline the release process, lower operational toil, and keep user data secure. What should you do?

  A. Implement Jenkins on local workstations.
  B. Implement Jenkins on Kubernetes on-premises.
  C. Implement Jenkins on Google Cloud Functions.
  D. Implement Jenkins on Compute Engine virtual machines.
  D. Implement Jenkins on Compute Engine virtual machines.

• Question 117:

  You have an application deployed to Cloud Run. A new version of the application has recently been deployed using the canary deployment strategy. Your Site Reliability Engineering (SRE) teammate informs you that an SLO has been exceeded for this application. You need to make the application healthy as quickly as possible. What should you do first?

  A. Configure traffic splitting to send 100% of the traffic to the latest revision.
  B. Configure traffic splitting to send 100% of the traffic to the previous revision.
  C. Create a new revision using the last known good version of the application.
  D. Identify the cause of the latency by using Cloud Trace.
  B. Configure traffic splitting to send 100% of the traffic to the previous revision.

• Question 118:

  Your organization wants to implement Site Reliability Engineering (SRE) culture and principles. Recently, a service that you support had a limited outage. A manager on another team asks you to provide a formal of what happened so they can action remediations. What should you do?

  A. Develop a postmortem that includes the root causes, resolution, lessons learned, and a prioritized list of action items. Share it with the manager only.
  B. Develop a postmortem that includes the root causes, resolution, lessons learned, and a prioritized list of action items. Share it on the engineering organization's document portal.
  C. Develop a postmortem that includes the root causes, resolution, lessons learned, the list of people responsible, and a list of action items for each person. Share it with the manager only.
  D. Develop a postmortem that includes the root causes, resolution, lessons learned, the list of people responsible, and a list of action items for each person. Share it on the engineering organization's document portal.
