An organization is developing a disaster recovery plan that requires data to be backed up and available at a moment ' s notice. Which of the following should the organization consider first to address this requirement?
A.
Implement a change management plan to ensure systems are using the appropriate versions.
B.
Hire additional on-call staff to be deployed if an event occurs.
C.
Design an appropriate warm site for business continuity.
D.
Identify critical business processes and determine associated software and hardware requirements.
For a disaster recovery (DR) plan requiring immediate data availability, the first step is understanding what needs to be protected and recovered. Identifying critical business processes and their associated software and hardware requirements establishes the foundation for the DR plan. This ensures that backups and recovery mechanisms align with business priorities, meeting the " moment ' s notice " requirement.
Option A:A change management plan is important for system consistency but doesn’t directly address immediate data availability in a DR context.
Option B:Hiring staff supports execution but doesn’t define what needs to be recovered or how. It’s a later step.
Option C:A warm site (a partially operational backup site) is a good DR solution, but designing it comes after identifying critical processes and resources.
Option D:This is the first step in any DR planning process—knowing what’s critical ensures the plan meets availability goals efficiently.
