Question 1

You support a Node.js application running on Google Kubernetes Engine (GKE) in production. The application makes several HTTP requests to dependent applications. You want to anticipate which dependent applications might cause performance issues. What should you do?

Options :

A : Instrument all applications with Stackdriver Profiler.

B : Instrument all applications with Stackdriver Trace and review inter-service HTTP requests.

C :

Use Stackdriver Debugger to review the execution of logic within each application to instrument all applications.

D :

Modify the Node.js application to log HTTP request and response times to dependent applications. Use Stackdriver Logging to find dependent applications that are performing poorly.

Answer: B

Question 2

Your application services run in Google Kubernetes Engine (GKE). You want to make sure that only images from your centrally-managed Google Container Registry (GCR) image registry in the altostrat-images project can be deployed to the cluster while minimizing development time. What should you do?

Options :

A : Create a custom builder for Cloud Build that will only push images to gcr.io/altostrat-images.

B : Use a Binary Authorization policy that includes the whitelist name pattern gcr.io/attostrat-images/.

C :

Add logic to the deployment pipeline to check that all manifests contain only images from gcr.io/altostrat-images.

D :

Add a tag to each image in gcr.io/altostrat-images and check that this tag is present when the image is deployed.

Answer: B

Question 3

What is the purpose of a Kubernetes object?

Options :

A : To represent a record of intent and ensure that the desired state is maintained according to the specified configuration.

B : To run multiple Pods on a single node

C : To manage Kubernetes clusters

D : To expose applications running on multiple nodes

Answer: A

Question 4

What are some key pointers related to snapshots in Cloud Debugger?

Options :

A : Snapshots can only be taken if a breakpoint is set on every line of code

B : Expressions cannot be included while configuring a snapshot

C : A snapshot is taken only once and can be manually retaken, and Cloud Debugger generates a new URL for every snapshot that-s been taken

D : Snapshots are taken automatically every few seconds

Answer: C

Question 5

For an augmented reality platform company that uses Google Cloud services, what is the best approach to securely integrate database credentials and other application secrets into the build pipeline using Cloud Build while minimizing development effort?

Options :

A : To secure the secrets, encrypt them on the client-side and keep them in a Cloud Storage bucket. Additionally, place a decryption key in the same bucket and provide Cloud Build access to the bucket.

B : To secure your secrets, you can establish a Cloud Storage bucket and utilize the inbuilt encryption feature. Then, you can save the confidential data in the bucket and allow Cloud Build access to it.

C : To encrypt the sensitive information and add it to your Cloud Build deployment configuration, utilize Cloud Key Management Service (Cloud KMS). Also, ensure to give KeyRing access to Cloud Build.

D : To secure the secrets, encrypt them and keep them in the application repository. Keep a separate repository for the decryption key and authorize Cloud Build to access it.
