- A
Continue current mitigation efforts and reassess after another hour.
Why wrong: With only 1 hour left until MTD, waiting may exceed downtime limits.
- B
Increase the capacity of the DDoS mitigation service.
Why wrong: While possible, this may not be enough; BC/DR activation should be considered.
- C
Escalate to the crisis management team to consider activating the disaster recovery plan.
This allows for a timely decision to invoke BC/DR before MTD expires.
- D
Notify customers of a prolonged outage.
Why wrong: Customer notification is important but should follow BC/DR activation if needed.
CISM Incident Management Practice Question
This CISM practice question tests your understanding of incident management. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
An organization has experienced a DDoS attack that is overwhelming its internet-facing services. The incident response team has implemented mitigations, but services remain degraded. The maximum tolerable downtime (MTD) for the affected services is 4 hours, and 3 hours have passed. Which of the following should the incident manager do NEXT?

Escalate to the crisis management team to consider activating the disaster recovery plan.

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CISM exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
