Google Professional Cloud DevOps Engineer Question 232
Select 3Google Cloud PlatformYour team is designing a new application that will run on Google Cloud. The application is expected to experience significant traffic spikes during peak hours, with potential usage exceeding the default quotas for Compute Engine instances in your project. What steps should you take to ensure the application can scale without hitting capacity limits during peak traffic?
- A
Request a quota increase for Compute Engine resources in the relevant regions.
- B
Migrate the application to a different cloud provider that offers unlimited resources.
- C
Use autoscaling to manage traffic spikes dynamically without worrying about quotas.
- D
Monitor quota usage with Cloud Monitoring and set up alerts to notify the team when usage approaches limits.
- E
Design the application to fail gracefully if quota limits are reached.
Show answer and explanation
Correct answers: A, D, E
Explanation
To handle capacity planning effectively, you need to proactively address quota limits by requesting increases, monitor usage to prevent unexpected bottlenecks, and design the system to handle scenarios where limits are reached. Autoscaling is a useful tool for managing traffic but is not sufficient if quota limits are not considered. Migrating to another cloud provider is impractical and unnecessary given the solutions available within GCP.
- A. Correct.
Requesting a quota increase ensures that the application has access to sufficient resources during peak traffic. It is a proactive step to handle anticipated usage beyond default limits.
- B. Incorrect.
Migrating to a different cloud provider is not a realistic or efficient solution for handling a capacity planning issue, especially when GCP provides mechanisms like quota increases and monitoring.
- C. Incorrect.
Autoscaling helps manage traffic spikes dynamically, but it does not address quota limits. If the quotas are exceeded, autoscaling cannot provision additional resources.
- D. Correct.
Monitoring quota usage and setting up alerts enable the team to take timely actions to mitigate potential issues when quota usage approaches limits.
- E. Correct.
Designing the application to fail gracefully ensures that user experience is minimally impacted in case quotas are exceeded. This is a critical part of designing resilient systems.
