Oracle Cloud Platform Data Integration 2020 Specialist — Question 28

With the volume of communication that can happen between different components in cloud-native applications, it is vital to not only test functionality, but also service resiliency.
Which statement is true with regards to service resiliency? (Choose the best answer.)

Answer options

• A. Resiliency is about recovering from failures without downtime or data loss.
• B. A goal of resiliency is not to bring a service to a functioning state after a failure.
• C. Resiliency testing can be only done in a test environment.
• D. Resiliency is about avoiding failures.

Correct answer: A

Explanation

The correct answer, A, defines resiliency as the ability to recover from failures without experiencing downtime or losing data, which is crucial for maintaining service continuity. Option B is incorrect because a primary goal of resiliency is indeed to restore functionality after a failure. Option C is misleading since resiliency testing can be conducted in production environments as well, not just in test environments. Option D is also incorrect, as resiliency focuses on managing and recovering from failures, not solely on preventing them.
