Question 12

- (Exam Topic 2)
You are developing a JPEG image-resizing API hosted on Google Kubernetes Engine (GKE). Callers of the service will exist within the same GKE cluster. You want clients to be able to get the IP address of the service.
What should you do?

A. Define a GKE Servic
B. Clients should use the name of the A record in Cloud DNS to find the service's cluster IP address.
C. Define a GKE Servic
D. Clients should use the service name in the URL to connect to the service.
E. Define a GKE Endpoin
F. Clients should get the endpoint name from the appropriate environment variable in the client container.
G. Define a GKE Endpoin
H. Clients should get the endpoint name from Cloud DNS.

Correct Answer:C

Question 13

- (Exam Topic 2)
You are developing an application that will be launched on Compute Engine instances into multiple distinct projects, each corresponding to the environments in your software development process (development, QA, staging, and production). The instances in each project have the same application code but a different configuration. During deployment, each instance should receive the application’s configuration based on the environment it serves. You want to minimize the number of steps to configure this flow.
What should you do?

A. When creating your instances, configure a startup script using the gcloud command to determine theproject name that indicates the correct environment.
B. In each project, configure a metadata key “environment” whose value is the environment it serve
C. Use your deployment tool to query the instance metadata and configure the application based on the “environment” value.
D. Deploy your chosen deployment tool on an instance in each projec
E. Use a deployment job to retrieve the appropriate configuration file from your version control system, and apply the configuration when deploying the application on each instance.
F. During each instance launch, configure an instance custom-metadata key named “environment” whose value is the environment the instance serve
G. Use your deployment tool to query the instance metadata, and configure the application based on the “environment” value.

Question 14

- (Exam Topic 2)
Your application takes an input from a user and publishes it to the user's contacts. This input is stored in a table in Cloud Spanner. Your application is more sensitive to latency and less sensitive to consistency. How should you perform reads from Cloud Spanner for this application?

A. Perform Read-Only transactions.
B. Perform stale reads using single-read methods.
C. Perform strong reads using single-read methods.
D. Perform stale reads using read-write transactions.

Question 15

- (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
https://cloud.google.com/build/docs/triggers
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.
