Question 960

A backup archive is rarely read and retrieval can wait hours at the lowest suitable storage price. What follow-up practice BEST maintains the desired outcome?

  1. Document instance-store data-loss behavior before deployment.
  2. Review minimum storage durations and retention exceptions.
  3. Review network access and file permissions.
  4. Set lifecycle transitions and account for retrieval charges.

Explanation

Correct Answer

D:

Set lifecycle transitions and account for retrieval charges. This continuing control fits because S3 archival tiers trade retrieval speed and access conditions for different storage economics. The associated appropriate response is: Evaluate an appropriate Amazon S3 Glacier archival storage class. An observable check is: A trial restore completes inside the documented acceptable retrieval window.

Incorrect Answers

A:

Instance store is tied to the physical host lifecycle and should not hold sole durable copies. In this question, however, s3 archival tiers trade retrieval speed and access conditions for different storage economics. The answer that meets the requirement is: Set lifecycle transitions and account for retrieval charges.

B:

Lifecycle rules automate object transitions or removals based on defined policies. In this question, however, s3 archival tiers trade retrieval speed and access conditions for different storage economics. The answer that meets the requirement is: Set lifecycle transitions and account for retrieval charges.

C:

EFS provides elastic file-system access to multiple supported clients, unlike one instance's local disk. In this question, however, s3 archival tiers trade retrieval speed and access conditions for different storage economics. The answer that meets the requirement is: Set lifecycle transitions and account for retrieval charges.

Question 961

An order processor needs a queue that buffers tasks until worker applications can consume them. What follow-up practice BEST maintains the desired outcome?
