Click on the arrows to vote for the correct answer
A. B. C. D.D.
It's interesting to note that the steps to resume normal processing operations will be different than the steps in the recovery plan; that is, the least critical work should be brought back first to the primary site.
My explanation: at the point where the primary site is ready to receive operations again, less critical systems should be brought back first because one has to make sure that everything will be running smoothly at the primary site before returning critical systems, which are already operating normally at the recovery site.
This will limit the possible interruption of processing to a minimum for most critical systems, thus making it the best option.

The correct answer is B. A salvage team's task is to ensure that the primary site returns to normal processing conditions.
Explanation:
Disaster recovery is a set of procedures that organizations follow to recover from a natural or human-made disaster that affects their information systems. The disaster recovery plan outlines how the organization will restore its critical IT systems, networks, and applications to normal operation after a disaster.
The following are the descriptions of the tasks of the recovery and salvage teams:
A. Recovery Team: The recovery team's primary task is to get the pre-defined critical business functions at the alternate backup processing site. This team is responsible for activating the disaster recovery plan, assessing the damage, and initiating the recovery process. The recovery team's goal is to restore critical business functions as quickly as possible.
B. Salvage Team: The salvage team's task is to ensure that the primary site returns to normal processing conditions. This statement is incorrect because the salvage team's task is not to ensure that the primary site returns to normal processing conditions. The salvage team is responsible for recovering the equipment, software, and data from the disaster site, cleaning it, and preparing it for reuse. The team ensures that the equipment and facilities are safe, secure, and in good condition before returning them to the primary site.
C. Disaster Recovery Plan: The disaster recovery plan should include how the company will return from the alternate site to the primary site. This statement is correct. The disaster recovery plan should include detailed procedures for returning from the alternate backup site to the primary site. This process should be carefully planned, tested, and documented to ensure that it can be executed quickly and efficiently.
D. Critical Applications: When returning to the primary site, the most critical applications should be brought back first. This statement is also correct. The organization should prioritize the restoration of critical applications and data first. This ensures that the most important business functions can resume as quickly as possible, minimizing the impact of the disaster.
In summary, the incorrect statement regarding disaster recovery is B. The salvage team's task is not to ensure that the primary site returns to normal processing conditions.
