Exam CISM topic 1 question 796 discussion

The keyword here is the "Ability to execute a DRP". The only one that talks about execution is option (B) Conducting a walk-through of the plan. Rationale: (A) Updating the plan periodically is great for preparation, but that is not execution. (C) Storing the plan at an offsite location is not ideal cause no execution is taking place. In fact, you can even say that it inhibits execution cause of the segregation. (D) Communicating the plan to all stakeholders is incorrect cause telling someone is not the same as executing it.

Going with B on this one - A walk-through has the greatest positive impact on the ability to execute a disaster recovery plan because it allows the organization to test the plan and to identify any areas that need to be improved. This helps to ensure that the plan is effective and that it can be executed in a timely manner in the event of a disaster.

B - This is a proactive measure that ensures all stakeholders understand their roles and responsibilities, and it helps identify any gaps or issues in the plan before an actual disaster occurs. Option D also important but simply communicating the plan does not guarantee that stakeholders will fully understand or be able to execute it effectively during a disaster.

D. Communicating the plan to all stakeholders. Communicating the disaster recovery plan (DRP) to all stakeholders has the greatest positive impact on the ability to execute the plan successfully. By ensuring that everyone involved understands their roles and responsibilities, as well as the steps to be taken during a disaster, the organization can coordinate efforts more effectively and respond promptly to mitigate the impact of the disaster. While updating the plan periodically, conducting walk-throughs, and storing the plan at an offsite location are all important aspects of disaster recovery planning, effective communication ensures that the plan can be implemented efficiently when needed.

According to ISACA online glossary: "Structured walk-through [test]—Identified key personnel walk through the plan to ensure that the plan accurately reflects the enterprise's ability to recover successfully." D is part of B, basically.

D. Communicating the plan to all stakeholders: This is crucial because a disaster recovery plan involves not just technical procedures but also the coordination and involvement of people. If stakeholders are unaware of the plan or their roles within it, it can lead to confusion and delays during an actual disaster. Effective communication ensures that everyone knows what to do and when to do it, which significantly impacts the plan's successful execution.

D. Communicating the plan to all stakeholders. Effective communication of the DRP to all stakeholders is crucial for its successful execution. By ensuring that all relevant stakeholders are aware of the plan, their roles and responsibilities, and the steps to be taken during a disaster, the organization can improve coordination, response time, and overall effectiveness in implementing the plan.

It should be A. If it does not have latest information, rest of the options are of no use.

Why not A? Updating it periodically?

All of the options listed can positively impact the ability to execute a disaster recovery plan (DRP), but if we have to choose the one with the GREATEST positive impact, it would be option D, "Communicating the plan to all stakeholders."
