The answer is the Technical Lead, as this role is specifically tasked with conducting forensic analysis during an incident response. This responsibility stems from the Technical Lead’s deep expertise in systems, networks, and data recovery, enabling them to examine digital evidence, identify the root cause, and preserve the chain of custody. On the Certified Information Security Manager CISM exam, this question tests your understanding of the incident response team structure and the distinct duties assigned to each role, often appearing in scenario-based items where you must match a function to the correct position. A common trap is confusing the Technical Lead’s analytical duties with the Incident Manager’s coordination tasks or the Communication Lead’s external reporting, so remember that analysis always falls under the technical domain. Memory tip: “Tech digs for facts” — the Technical Lead is the one who gets their hands dirty with the forensic data.
CISM Incident Management Practice Question
This CISM practice question tests your understanding of incident management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Exhibit
Refer to the exhibit.
[Incident Response Plan Roles]
Role: Incident Manager - Coordinates response
Role: Technical Lead - Performs analysis
Role: Communication Lead - Handles communications
Role: Legal Counsel - Provides legal guidance
According to the exhibit, which role is responsible for conducting forensic analysis?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Technical Lead
Option A is correct because the Technical Lead is responsible for analysis. Option B is wrong because the Incident Manager coordinates. Option C is wrong because Communication Lead handles communications. Option D is wrong because Legal Counsel provides legal guidance.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CISM NAT questions on configuration and troubleshooting.

The correct answer is: Technical Lead — Option A is correct because the Technical Lead is responsible for analysis. Option B is wrong because the Incident Manager coordinates. Option C is wrong because Communication Lead handles communications. Option D is wrong because Legal Counsel provides legal guidance.
