Google Professional Cloud DevOps Engineer Question 94
Select 3Google Cloud PlatformYour team is managing a critical customer-facing application hosted on Google Cloud. The business wants to release new features weekly to stay competitive, but recent outages caused by rushed deployments have negatively impacted customer trust. As a DevOps Engineer, how can you ensure both rapid feature delivery and high service reliability?
- A
Implement a progressive delivery strategy, such as canary releases or blue/green deployments, to test changes on a subset of users before full rollout.
- B
Adopt an Infrastructure as Code (IaC) approach to automate environment consistency and reduce configuration drift.
- C
Set up an SLO (Service Level Objective) and error budget to balance feature velocity with reliability thresholds.
- D
Delay all feature releases until exhaustive manual testing is completed to ensure reliability.
- E
Introduce a continuous delivery pipeline with automated testing, monitoring, and rollback mechanisms.
Show answer and explanation
Correct answers: A, C, E
Explanation
Balancing change velocity and reliability requires strategies that enable safe, fast deployments while maintaining service quality. Progressive delivery methods, SLOs with error budgets, and robust continuous delivery pipelines are critical for this balance. These approaches minimize risk, provide clear trade-offs between velocity and reliability, and automate safeguards for rapid iteration.
- A. Correct.
This is correct. Progressive delivery strategies like canary releases or blue/green deployments allow you to validate changes with minimal risk, ensuring reliability while enabling faster deployments.
- B. Incorrect.
While IaC is a good practice for managing infrastructure, it doesn't directly address the need to balance feature velocity with service reliability in this scenario.
- C. Correct.
This is correct. SLOs and error budgets provide a measurable framework to balance the pace of change with acceptable reliability thresholds.
- D. Incorrect.
This is incorrect. Delaying all feature releases until manual testing is exhaustive sacrifices velocity unnecessarily and is not aligned with DevOps practices.
- E. Correct.
This is correct. A continuous delivery pipeline with automated testing, monitoring, and rollback mechanisms ensures both faster releases and safeguards for reliability.
