Question 176

You support a high-traffic web application and want to ensure that the home page loads in a timely manner. As a first step, you decide to implement a Service Level Indicator (SLI) to represent home page request latency with an acceptable page load time set to 100 ms. What is the Google-recommended way of calculating this SLI?

A.Count the number of home page requests that load in under 100 ms. and then divide by the total number of all web application requests.

B.Buckelize Ihe request latencies into ranges, and then compute the percentile at 100 ms.

C.Count the number of home page requests that load in under 100 ms, and then divide by the total number of home page requests.

D.Bucketize the request latencies into ranges, and then compute the median and 90th percentiles.

Question 177

You have migrated an e-commerce application to Google Cloud Platform (GCP). You want to prepare the application for the upcoming busy season. What should you do first to prepare for the busy season?

A.Create a runbook on inflating the disaster recovery (DR) environment if there is growth.

B.Load teat the application to profile its performance for scaling.

C.Pre-provision double the compute power used last season, expecting growth.

D.Enable AutoScaling on the production clusters, in case there is growth.

Question 178

You are writing a postmortem for an incident that severely affected users. You want to prevent similar incidents in the future. Which two of the following sections should you include in the postmortem? (Choose two.)

A.An explanation of the root cause of the incident

B.A list of employees responsible for causing the incident

C.Copies of the design documents for all the services impacted by the incident

D.A list of action items to prevent a recurrence of the incident

E.Your opinion of the incident's severity compared to past incidents

Question 179

You need to build a CI/CD pipeline for a containerized application in Google Cloud Your development team uses a central Git repository for trunk-based development You want to run all your tests in the pipeline for any new versions of the application to improve the quality What should you do?

A.1. Install a Git hook to require developers to run unit tests before pushing the code to a central repository
2. Trigger Cloud Build to build the application container Deploy the application container to a testing environment, and run integration tests
3. If the integration tests are successful deploy the application container to your production environment.
and run acceptance tests

B.1. Install a Git hook to require developers to run unit tests before pushing the code to a central repository If all tests are successful build a container
2. Trigger Cloud Build to deploy the application container to a testing environment, and run integration tests and acceptance tests
3. If all tests are successful tag the code as production ready Trigger Cloud Build to build and deploy the application container to the production environment

C.1. Trigger Cloud Build to build the application container and run unit tests with the container
2. If unit tests are successful, deploy the application container to a testing environment, and run integration tests
3. If the integration tests are successful the pipeline deploys the application container to the production environment After that, run acceptance tests

D.1. Trigger Cloud Build to run unit tests when the code is pushed If all unit tests are successful, build and push the application container to a central registry.
2. Trigger Cloud Build to deploy the container to a testing environment, and run integration tests and acceptance tests
3. If all tests are successful the pipeline deploys the application to the production environment and runs smoke tests

Question 180

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.
