Question 43

- (Exam Topic 2)
You are deploying a microservices application to Google Kubernetes Engine (GKE) that will broadcast livestreams. You expect unpredictable traffic patterns and large variations in the number of concurrent users. Your application must meet the following requirements:
• Scales automatically during popular events and maintains high availability
• Is resilient in the event of hardware failures
How should you configure the deployment parameters? (Choose two.)

A. Distribute your workload evenly using a multi-zonal node pool.

B. Distribute your workload evenly using multiple zonal node pools.

C. Use cluster autoscaler to resize the number of nodes in the node pool, and use a Horizontal Pod Autoscaler to scale the workload.

D. Create a managed instance group for Compute Engine with the cluster node

E. Configure autoscaling rules for the managed instance group.

F. Create alerting policies in Cloud Monitoring based on GKE CPU and memory utilizatio

G. Ask an on-duty engineer to scale the workload by executing a script when CPU and memory usage exceed predefined thresholds.

Correct Answer:AC

Question 44

- (Exam Topic 2)
You are developing a new web application using Cloud Run and committing code to Cloud Source Repositories. You want to deploy new code in the most efficient way possible. You have already created a Cloud Build YAML file that builds a container and runs the following command: gcloud run deploy. What should you do next?

A. Create a Pub/Sub topic to be notified when code is pushed to the repositor

B. Create a Pub/Sub trigger that runs the build file when an event is published to the topic.

C. Create a build trigger that runs the build file in response to a repository code being pushed to the development branch.

D. Create a webhook build trigger that runs the build file in response to HTTP POST calls to the webhook URL.

E. Create a Cron job that runs the following command every 24 hours: gcloud builds submit.

Correct Answer:B

Cloud Build uses build triggers to enable CI/CD automation. You can configure triggers to listen for incoming events, such as when a new commit is pushed to a repository or when a pull request is initiated, and then automatically execute a build when new events come in. You can also configure triggers to build code on any changes to your source repository or only on changes that match certain criteria.

Question 46

- (Exam Topic 2)
You are writing a single-page web application with a user-interface that communicates with a third-party API for content using XMLHttpRequest. The data displayed on the UI by the API results is less critical than other data displayed on the same web page, so it is acceptable for some requests to not have the API data
displayed in the UI. However, calls made to the API should not delay rendering of other parts of the user interface. You want your application to perform well when the API response is an error or a timeout. What should you do?

A. Set the asynchronous option for your requests to the API to false and omit the widget displaying the API results when a timeout or error is encountered.

B. Set the asynchronous option for your request to the API to true and omit the widget displaying the API results when a timeout or error is encountered.

C. Catch timeout or error exceptions from the API call and keep trying with exponential backoff until theAPI response is successful.

D. Catch timeout or error exceptions from the API call and display the error response in the UI widget.

Correct Answer:A

Question 47

- (Exam Topic 2)
Your company wants to expand their users outside the United States for their popular application. The company wants to ensure 99.999% availability of the database for their application and also wants to minimize the read latency for their users across the globe.
Which two actions should they take? (Choose two.)

A. Create a multi-regional Cloud Spanner instance with "nam-asia-eur1" configuration.

B. Create a multi-regional Cloud Spanner instance with "nam3" configuration.

C. Create a cluster with at least 3 Spanner nodes.

D. Create a cluster with at least 1 Spanner node.

E. Create a minimum of two Cloud Spanner instances in separate regions with at least one node.

F. Create a Cloud Dataflow pipeline to replicate data across different databases.

Correct Answer:BF

Question 48

- (Exam Topic 2)
You have an application deployed in production. When a new version is deployed, some issues don't arise until the application receives traffic from users in production. You want to reduce both the impact and the number of users affected.
Which deployment strategy should you use?

A. Blue/green deployment

B. Canary deployment

C. Rolling deployment

D. Recreate deployment

Correct Answer:A
