Certified Information Systems Security Professional (CISSP) — Question 247

When designing a business continuity plan (BCP), what is the formula to determine the Maximum Tolerable Downtime (MTD)?

Answer options

• A. Estimated Maximum Loss (EML) + Recovery Time Objective (RTO)
• B. Business impact analysis (BIA) + Recovery Point Objective (RPO)
• C. Annual Loss Expectancy (ALE) + Work Recovery Time (WRT)
• D. Recovery Time Objective (RTO) + Work Recovery Time (WRT)

Correct answer: D

Explanation

The correct answer is D because Maximum Tolerable Downtime (MTD) is calculated by combining the Recovery Time Objective (RTO) and the Work Recovery Time (WRT). Options A, B, and C include incorrect components that do not accurately represent the relationship necessary for determining MTD.
