Free Google Professional-Cloud-Developer Exam Questions

Question 1

Your team has created an application that is hosted on a Google Kubernetes Engine (GKE) cluster. You need to connect the application to a legacy REST service that is deployed in two GKE clusters in two different regions. You want to connect your application to the target service in a way that is resilient. You also want to be able to run health checks on the legacy service on a separate port. How should you set up the connection? (Choose two.)

A : Traffic Director with a sidecar proxy to connect the application to the service.

B : a proxyless Traffic Director configuration to connect the application to the service.

C : nfigure the legacy service's firewall to allow health checks originating from the proxy.

D : nfigure the legacy service's firewall to allow health checks originating from the application.

E : nfigure the legacy service's firewall to allow health checks originating from the Traffic Director control plane.

Answer: A,C

Question 2

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 3

What is the best way to monitor the performance of each integration in a microservice-oriented architecture using Cloud Trace?

A : By implementing Cloud Trace in every single integration

B : By monitoring only the most critical tasks of the app

C : By creating a general performance diagnosis for the entire application

D : By implementing Cloud Trace in each of the services

Answer: D

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

Your web application is deployed to the corporate intranet. You need to migrate the web application to Google Cloud. The web application must be available only to company employees and accessible to employees as they travel. You need to ensure the security and accessibility of the web application while minimizing application changes. What should you do?

A : nfigure the application to check authentication credentials for each HTTP(S) request to the application.

B : nfigure Identity-Aware Proxy to allow employees to access the application through its public IP address.

C : nfigure a Compute Engine instance that requests users to log in to their corporate account. Change the web application DNS to point to the proxy Compute Engine instance. After authenticating, the Compute Engine instance forwards requests to and from the web application.

D : nfigure a Compute Engine instance that requests users to log in to their corporate account. Change the web application DNS to point to the proxy Compute Engine instance. After authenticating, the Compute Engine issues an HTTP redirect to a public IP address hosting the web application.

Answer: B
