Question 1

You work at a rapidly growing financial technology startup. You manage the payment processing application

written in Go and hosted on Cloud Run in the Singapore region (asia-southeast1). The payment processing

application processes data stored in a Cloud Storage bucket that is also located in the Singapore region.

The startup plans to expand further into the Asia Pacific region. You plan to deploy the Payment Gateway in

Jakarta, Hong Kong, and Taiwan over the next six months. Each location has data residency requirements that

require customer data to reside in the country where the transaction was made. You want to minimize the cost

of these deployments. What should you do?

A : eate a Cloud Storage bucket in each region, and create a Cloud Run service of the payment processing application in each region

B : eate a Cloud Storage bucket in each region, and create three Cloud Run services of the payment processing application in the Singapore region.

C : Create three Cloud Storage buckets in the Asia multi-region, and create three Cloud Run services of the payment processing application in the Singapore region

D : eate three Cloud Storage buckets in the Asia multi-region, and create three Cloud Run revisions of the payment processing application in the Singapore region.

Answer: A

Question 2

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

Question 3

You are developing an application that consists of several microservices running in a Google Kubernetes Engine cluster. One microservice needs to connect to a third-party database running on-premises. You need to store credentials to the database and ensure that these credentials can be rotated while following security best practices. What should you do?

A : ore the credentials in a sidecar container proxy. and use it to connect to the third-party database.

B : nfigure a service mesh to allow or restrict traffic from the Pods in your microservice to the database.

C : ore the credentials in an encrypted volume mount, and associate a Persistent Volume Claim with the client Pod.

D : Store the credentials as a Kubemetes Secret, and use the Cloud Key Management Service plugin to handle encryption and decryption

Answer: A

Question 4

Your company's development teams want to use various open source operating systems in their Docker builds. When images are created in published containers in your company's environment, you need to scan them for Common Vulnerabilities and Exposures (CVEs) The scanning process must not impact software development agility. You want to use managed services where possible. What should you do?

A : able the Vulnerability scanning setting in the Container Registry.

B : eate a Cloud Function that is triggered on a code check-in and scan the code for CVEs.

C : allow the use of non-commercially supported base images in your development environment

D : Cloud Monitoring to review the output of Cloud Build to determine whether a vulnerable version has been used

Answer: A

Question 5

Azgomi is a popular community application that facilitates communication between people in close proximity. It is used for event planning, organizing sporting events, and connecting businesses with their local communities. Although it launched recently in a few neighborhoods in Dallas, it is rapidly expanding into a global phenomenon. The company's venture capital investors are looking for rapid growth and expansion into new regions, offering the same experience to users, regardless of their location.

Azgomi wants to expand its service to new regions, with updated functionality to better serve its global customers. They plan to hire and train a new team to support these regions in their respective time zones. It is essential that the application scales smoothly and provides clear uptime data, and that they analyze and respond to any issues that occur. The existing technical environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform. The application runs on Compute Engine virtual machine instances hosted in GCP. State is stored in a single instance MySQL database in GCP. Release cycles include development freezes to allow for QA testing. The application has no logging. Applications are manually deployed by infrastructure engineers during periods of slow traffic on weekday evenings. There are basic indicators of uptime, and alerts are frequently fired when the APIs are unresponsive.

Azgomi's investors want to expand its footprint and support the increase in demand they are seeing. They require the following:

• Expand availability of the application 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 understand how to monetize their product.

• Ensure compliance with regulations in the new regions (for example, GDPR).

• Reduce infrastructure management time and cost.

• Adopt Google-recommended practices for cloud computing.

○ Develop standardized workflows and processes around application lifecycle management.

○ Define service level indicators (SLIs) and service level objectives (SLOs).

The technical requirements for Azgomi include:

• Providing secure communications between the on-premises data center and cloud-hosted applications and infrastructure.

• The application must provide usage metrics and monitoring.

• APIs require authentication and authorization.

• Implement faster and more accurate validation of new features.

• Logging and performance metrics must provide actionable information to be able to provide debugging information and alerts.

• Must scale to meet user demand.

What steps can Azgomi take to revamp their architecture in order to accommodate a significant surge in user traffic?

A : Use multiple Compute Engine instances to run MySQL to store state information. Use a Google Cloud-managed load balancer to distribute the load between instances. Use managed instance groups for scaling.

B : Use Google Kubernetes Engine (GKE) to run the application as a microservice. Run the MySQL database on a dedicated GKE node.

C : Use a Cloud Storage bucket to host the application as a static website, and use another Cloud Storage bucket to store user data.

D : Use Memorystore to store session information and CloudSQL to store state information. Use a Google Cloud-managed load balancer to distribute the load between instances. Use managed instance groups for scaling.

Answer: C
