ISC2 CC Practice Question: Business Continuity, Disaster Recovery, and Incident Response
An organization is preparing its Business Continuity Plan (BCP). Which process identifies critical business functions and the impact of disruptions?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Business Impact Analysis (BIA)
A Business Impact Analysis (BIA) identifies critical business functions, dependencies, and the impact of disruptions, providing metrics like MTD, RTO, and RPO.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Incident Response Plan (IRP)
Why it's wrong here
An IRP contains and recovers from active security incidents; it neither catalogues critical business functions nor quantifies disruption impact, which is business impact analysis. It is tempting because incident response and continuity planning both address disruption, but an IRP is the correct choice when the scenario asks how to detect, contain and eradicate an in-progress attack.
- ✗
Disaster Recovery Plan (DRP)
Why it's wrong here
A DRP focuses on restoring IT infrastructure after a disaster, not on identifying critical business functions and their disruption impact. It is tempting because BCP and DRP are closely related in continuity planning, and a DRP would be correct if the question asked specifically about recovering technology systems after an outage, rather than the initial business-impact analysis that defines which functions must be prioritised.
- ✗
Risk Assessment
Why it's wrong here
Risk Assessment identifies and ranks threats, vulnerabilities and likelihoods; it does not determine which business functions are critical or the operational impact of their loss, which is business impact analysis. It is tempting because both feed the BCP, but Risk Assessment is correct when the scenario asks which risks to treat and in what priority.
- ✓
Business Impact Analysis (BIA)
Why this is correct
A Business Impact Analysis identifies critical business functions and quantifies the operational and financial impact of their disruption, plus dependencies and recovery priorities. It is the BCP process that satisfies the stem's requirement to identify functions and disruption impact.
