Question

A disaster recovery team learned of several mistakes that were made during the last disaster recovery parallel test. Computational resources ran out at 70% of restoration of critical services.

Which of the following should be modified to prevent the issue from reoccurring?

Answers
  1. correct
Explanation

The correct answer is: D. Recovery service level

The recovery service level defines the capacity and performance requirements needed for the systems during the recovery process. If computational resources ran out during the disaster recovery test, it indicates that the recovery service level was not properly planned or configured to handle the required load for restoring critical services. Adjusting the recovery service level ensures that sufficient resources are allocated to prevent a similar issue in the future.

Why the other options are incorrect:

  1. Recovery point objective (RPO)

    • The recovery point objective refers to the acceptable amount of data loss measured in time (e.g., restoring to a backup no older than X hours). It does not relate to resource allocation or computational capacity during the recovery process.
  2. Recovery time objective (RTO)

    • The recovery time objective defines the maximum acceptable downtime before services are fully restored. While important, it does not directly address the problem of running out of computational resources during recovery.
  3. Mission-essential functions

    • Mission-essential functions refer to the critical operations that must be prioritized during recovery. While identifying these functions is vital, the issue here is not the prioritization of tasks but rather the allocation of resources to support those tasks.
