ISC2 CC Practice Question: Business Continuity, Disaster Recovery, and Incident Response
A software-as-a-service (SaaS) provider is developing its business continuity plan (BCP). The company wants to ensure it can continue operating during a prolonged power outage at its primary data center. Which element of the BCP should address the alternate power source and its regular testing?
⚠ Common exam trap
Candidates often confuse the business impact analysis, which identifies the need for power continuity, with the continuity strategy, which actually documents the alternate power source and its testing.
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
✓
Continuity strategies
Continuity strategies are the component of the business continuity plan that outlines how critical functions will be maintained during disruptions, including the use of alternate power sources. They specify the resources, responsibilities, and testing required to ensure the strategy works. The BIA identifies the need, but the strategy provides the solution.
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
The incident response plan focuses on detecting, containing, and recovering from security incidents such as breaches or malware. A power outage is an availability disruption, not a security incident, so the IRP is not the appropriate document. While the IRP may reference business continuity for severe incidents, it does not typically contain details about generators or power testing, which belong in continuity planning.
- ✓
Continuity strategies
Why this is correct
Continuity strategies describe the specific approaches and resources, such as alternate power sources, that will be used to maintain critical functions during a disruption. For a prolonged power outage, the strategy would include details on generators, uninterruptible power supplies, fuel contracts, and testing schedules. This element directly addresses how the SaaS provider will keep operating and ensures the power solution is documented and exercised.
- ✗
Disaster recovery plan (DRP)
Why it's wrong here
The disaster recovery plan is a subset of business continuity that focuses on restoring IT infrastructure and systems after a disaster. While a DRP may include power restoration steps, the broader question of maintaining business operations during a prolonged outage falls under continuity strategies. The DRP is more about recovery of technology, whereas the continuity strategy defines the overall approach to keep the business running.
- ✗
Business impact analysis (BIA)
Why it's wrong here
A business impact analysis identifies critical business functions and the effects of disruption, but it does not specify technical solutions like alternate power. The BIA would determine how long the SaaS provider can tolerate an outage and what the impact would be, but the actual power contingency is documented in the continuity strategies or plan itself. The BIA informs the strategy but is not the element that addresses the power source.
