Google Professional Cloud Developer Question 25
Select 2Google Cloud PlatformYou are designing a highly available web application on Google Cloud that serves users across multiple continents. The application requires low latency, redundancy, and disaster recovery capabilities. Which of the following design choices should you make to meet these requirements?
- A
Deploy the application across multiple regions and use a global HTTP(S) Load Balancer.
- B
Deploy the application in a single region using zonal services for cost efficiency.
- C
Store application data in a multi-region Cloud Storage bucket to ensure low-latency access and high availability.
- D
Use regional Cloud SQL instances for all database needs to ensure proximity to the application.
- E
Configure Compute Engine instances in a single zone to minimize deployment complexity.
Show answer and explanation
Correct answers: A, C
Explanation
To meet the requirements of low latency, redundancy, and disaster recovery, the application should be deployed across multiple regions with a global HTTP(S) Load Balancer to route traffic efficiently. Using a multi-region Cloud Storage bucket ensures high availability and low-latency access to data globally. Other options, such as deploying in a single region or zone, do not provide sufficient redundancy or disaster recovery capabilities.
- A. Correct.
Deploying across multiple regions with a global HTTP(S) Load Balancer ensures low latency by routing traffic to the nearest region and provides redundancy in case of a regional failure.
- B. Incorrect.
Using a single region and zonal services prioritizes cost efficiency but does not meet the requirements for high availability, redundancy, or low-latency global access.
- C. Correct.
Storing data in a multi-region Cloud Storage bucket provides high availability and low-latency access to data for users across different locations, meeting the application's requirements.
- D. Incorrect.
While regional Cloud SQL instances ensure proximity to the application, they do not provide redundancy across regions and may result in higher latency for users in distant locations.
- E. Incorrect.
Configuring Compute Engine instances in a single zone increases the risk of downtime if the zone experiences an outage and does not support high availability or disaster recovery.
