Question 1

Your application is deployed in a Google Kubernetes Engine (GKE) cluster. When a new version of your application is released, your CI/CD tool updates the spec.template.spec.containers[0].image value to reference the Docker image of your new application version. When the Deployment object applies the change, you want to deploy at least 1 replica of the new version and maintain the previous replicas until the new replica is healthy. Which change should you make to the GKE Deployment object shown below?

A : t the Deployment strategy to RollingUpdate with maxSurge set to 0, maxUnavailable set to 1.

B : t the Deployment strategy to RollingUpdate with maxSurge set to 1, maxUnavailable set to 0.

C : t the Deployment strategy to Recreate with maxSurge set to 0, maxUnavailable set to 1.

D : t the Deployment strategy to Recreate with maxSurge set to 1, maxUnavailable set to 0.

Answer: D

Question 2

Azgomi is a community application that facilitates communication between people in close proximity, used for event planning and organizing sporting events, and for businesses to connect with their local communities. Azgomi's unique style of hyper-local community communication and business outreach is in demand around the world. The executive statement is to expand the number one local community app globally. The solution concept is to expand their existing service in new regions to better serve their global customers, and hire and train a new team to support these regions in their time zones. Azgomi wants to ensure the application scales smoothly and provides clear uptime data, and that they analyze and respond to any issues that occur. Their existing technical environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform.

Azgomi's investors want to expand their footprint and support the increase in demand they are seeing. They require the application to expand availability to new regions, support 10x as many concurrent users, ensure a consistent experience for users when they travel to different regions, obtain user activity metrics to better monetize their product, ensure compliance with regulations in new regions, reduce infrastructure management time and cost, and adopt Google-recommended practices for cloud computing. The technical requirements include providing secure communications between the on-premises data center and cloud-hosted applications and infrastructure, providing usage metrics and monitoring, requiring authentication and authorization for APIs, implementing faster and more accurate validation of new features, providing actionable information for logging and performance metrics, and scaling to meet user demand.

A recent security audit discovered that Azgomi's database credentials for their Compute Engine-hosted MySQL databases are stored in plain text on persistent disks. Azgomi needs to reduce the risk of these credentials being stolen.

What actions do you suggest for them?

A : Create a service account and download its key. Use it to authenticate to Cloud KMS for database credentials.

B : Create a service account and use its key to authenticate to Cloud KMS for a decryption key to access the database credentials.

C : Create a service account and give it the roles/iam.serviceAccountUser role. Authenticate using Cloud SQL Proxy while impersonating this account.

D : Grant the roles/secretmanager.secretAccessor role to the Compute Engine service account and use Secret Manager API to store and access the database credentials.

Answer: C

Question 3

You have recently instrumented a new application with OpenTelemetry, and you want to check the latency of your application requests in Trace. You want to ensure that a specific request is always traced. What should you do?

A : it 10 minutes, then verify that Trace captures those types of requests automatically.

B : ite a custom script that sends this type of request repeatedly from your dev project.

C : the Trace API to apply custom attributes to the trace

D : the X-Cloud-Trace-Context header to the request with the appropriate parameters

Answer: D

Question 4

You have been requested by your colleague to examine the code below, which is responsible for adding a credit to an account balance in Cloud Datastore.

What suggestion do you have for your teammate to improve?

A : Utilize a transactional database with strong consistency.

B : Get and store the entity within a transaction.

C : Avoid returning the account entity from the function.

D : Get the entity with an ancestor query.

Answer: D

Question 5

You are developing a new application that has the following design requirements:

Creation and changes to the application infrastructure are versioned and auditable.

The application and deployment infrastructure uses Google-managed services as much as possible.

The application runs on a serverless compute platform.

How should you design the application’s architecture?

A : 1. Store the application and infrastructure source code in a Git repository.2. Use Cloud Build to deploy the application infrastructure with Terraform.3. Deploy the application to a Cloud Function as a pipeline step.

B : 1. Deploy Jenkins from the Google Cloud Marketplace, and define a continuous integration pipeline inJenkins.2. Configure a pipeline step to pull the application source code from a Git repository.3. Deploy the application source code to App Engine as a pipeline step.

C : 1. Create a continuous integration pipeline on Cloud Build, and configure the pipeline to deploy theapplication infrastructure using Deployment Manager templates.2. Configure a pipeline step to create a container with the latest application source code.3. Deploy the container to a Compute Engine instance as a pipeline step.

D : 1. Deploy the application infrastructure using gcloud commands.2. Use Cloud Build to define a continuous integration pipeline for changes to the application source code.3. Configure a pipeline step to pull the application source code from a Git repository, and create acontainerized application.4. Deploy the new container on Cloud Run as a pipeline step.

Answer: D
