Question 3

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 4

The case study involves Azgomi, a community application used for event planning, organizing sporting events, and for businesses to connect with their local communities. It has recently launched in a few neighborhoods in Dallas and is rapidly growing into a global phenomenon. Its unique style of hyper-local community communication and business outreach is in demand around the world.

The executive statement is to take the local community services global, with the venture capital investors wanting to see rapid growth and the same great experience for new local and virtual communities that come online, whether their members are 10 or 10000 miles away from each other.

Azgomi wants to expand their existing service with updated functionality in new regions to better serve their global customers. They plan to hire and train a new team to support these regions in their time zones. They also need to ensure that the application scales smoothly and provides clear uptime data.

Azgomi's existing technical environment is a mix of on-premises hardware and infrastructure running in Google Cloud Platform. They have limited experience in global-scale applications.

The business requirements are to expand the availability of the application to new regions, increase the number of concurrent users that can be supported, 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, reduce infrastructure management time and cost, and adopt the Google-recommended practices for cloud computing.

The technical requirements are that the application and backend must provide usage metrics and monitoring, APIs require strong authentication and authorization, logging must be increased, and data should be stored in a cloud analytics platform. They must move to serverless architecture to facilitate elastic scaling and provide authorized access to internal apps in a secure manner.

What is the most suitable method for Azgomi to store their application state to fulfill their business needs?

A : Put a memcache layer in front of MySQL.

B : Replace the MySQL instance with Cloud SQL.

C : Move the state storage to Cloud Spanner.

D : Use local SSDs to store state.

Answer: B

Question 5

You are supporting a business-critical application in production deployed on Cloud Run. The application is reporting HTTP 500 errors that are affecting the usability of the application. You want to be alerted when the number of errors exceeds 15% of the requests within a specific time window. What should you do?

A : eate a Cloud Function that consumes the Cloud Monitoring API. Use Cloud Scheduler to trigger the Cloud Function daily and alert you if the number of errors is above the defined threshold

B : vigate to the Cloud Run page in the Google Cloud console, and select the service from the services list. Use the Metrics tab to visualize the number of errors for that revision, and refresh the page daily.

C : eate an alerting policy in Cloud Monitoring that alerts you if the number of errors is above the defined threshold.

D : eate a Cloud Function that consumes the Cloud Monitoring API. Use Cloud Composer to trigger the Cloud Function daily and alert you if the number of errors is above the defined threshold.

Answer: C
