Google Professional Cloud Developer Question 29
Select 4Google Cloud PlatformYou are developing a global e-commerce application on Google Cloud that requires low-latency responses for users in different regions. The application uses both Compute Engine and Cloud Storage. Which of the following design decisions align with Google Cloud's geographical distribution and ensure optimal latency and reliability?
- A
Deploy Compute Engine instances in multiple regions close to your user base.
- B
Use a multi-regional Cloud Storage bucket to store static assets like product images.
- C
Deploy all Compute Engine instances in a single region to simplify network configuration.
- D
Use a regional Cloud Storage bucket in a region close to your Compute Engine instances for storing transactional data.
- E
Configure a global external HTTP(S) load balancer to route traffic to the nearest regional Compute Engine instance.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
Google Cloud's geographical distribution allows developers to optimize latency and reliability by strategically placing resources close to users and using services designed for global availability. Multi-regional Cloud Storage buckets ensure high availability for static assets, while regional buckets are ideal for latency-sensitive, compute-related data. Deploying Compute Engine instances across regions and leveraging global load balancers further enhances user experience by reducing latency and ensuring traffic is routed efficiently.
- A. Correct.
Correct: Deploying Compute Engine instances in multiple regions ensures low-latency responses by serving users from a region geographically close to them.
- B. Correct.
Correct: Multi-regional Cloud Storage buckets are designed for low-latency, high-availability storage across multiple regions, making them ideal for global static content delivery.
- C. Incorrect.
Incorrect: Deploying all instances in a single region can lead to higher latency for users located far from that region and increases the risk of a single point of failure.
- D. Correct.
Correct: Using a regional Cloud Storage bucket close to your Compute Engine instances minimizes latency for transactional data that requires frequent interaction with the Compute Engine instances.
- E. Correct.
Correct: A global external HTTP(S) load balancer routes user traffic to the nearest available Compute Engine instance, improving latency and reliability for a geographically distributed user base.
