CISSP Practice Question: What would MOST likely occur if a company neglects to regularly test…

Correct Answer: A. Increased downtime during incidents

Explanation (CISSP Manager Logic):

Untested incident response plans lead to operational paralysis and uncoordinated actions during a crisis. Regular testing identifies gaps in procedures and ensures the team can restore critical business functions quickly, minimizing the financial impact of an outage.

By implementing this solution, you:

• Reduce the Mean Time to Recover (MTTR) for critical services.
• Validate that technical controls and communication channels work as intended.
• Ensure compliance with regulatory requirements for business resilience.

While the other options are relevant, they fall short because:

• B: Efficiency decreases when staff are unfamiliar with their specific roles and responsibilities during an active threat.
• C: Morale typically drops when employees face the stress of chaotic, unmanaged security incidents.
• D: While testing costs money upfront, neglecting it leads to much higher emergency recovery and reputational costs.

Think like a manager:

Preparation is a business investment in resilience. A manager must prioritize tabletop exercises and functional tests to ensure the organization can maintain its mission-essential functions under duress.
