CHFI Incident Response and First Responder Skills Practice Question
This CHFI practice question tests your understanding of incident response and first responder skills. 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.
Which TWO actions are essential for a first responder when securing an incident scene involving a compromised server? (Select exactly two.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Document the system’s date and time settings for accurate timeline reconstruction.
Option B is correct because the system's date and time settings are critical for establishing a reliable timeline of events during forensic analysis. The first responder must document these settings (e.g., from the BIOS or operating system) before any changes occur, as they directly affect the timestamps of file system metadata (MAC times) and log entries. Without this baseline, correlating events across multiple sources becomes unreliable, potentially invalidating the entire investigation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Run antivirus scans to identify and remove any malware present.
Why it's wrong here
Running scans alters the system state and may destroy evidence.
✓
Document the system’s date and time settings for accurate timeline reconstruction.
Why this is correct
Time settings are crucial for correlating events.
Clue confirmation
The clue word "first" in the question point toward this answer.

✓
Photograph the physical setup, including all cables and peripheral connections.
Why this is correct
Visual documentation preserves the physical state.

✗
Reboot the system into safe mode to prevent further damage.
Why it's wrong here
Rebooting destroys volatile evidence.
✗
Connect an external hard drive to create a backup of important files.
Why it's wrong here
Connecting storage can modify the system and evidence.
Common exam traps
Common exam trap: answer the scenario, not the keyword
EC-Council often tests the misconception that proactive remediation (like scanning or backing up) is part of first responder duties, when in fact the priority is preservation of volatile and non-volatile evidence without any alteration.
Detailed technical explanation
How to think about this question
Under the hood, the system clock is typically maintained by the CMOS/BIOS and synchronized via NTP; documenting its offset from UTC (e.g., using `w32tm /query /status` on Windows or `timedatectl` on Linux) allows forensic tools to normalize timestamps across different time zones. A real-world scenario: if a server's clock was skewed by 5 minutes due to a failing CMOS battery, an attacker's actions might appear to occur after the incident response started, leading to incorrect conclusions about the attack timeline. This is why the first responder must capture the exact system time and time zone before any interaction that could alter it.
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.
TExam Day Tips
→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 CHFI 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.
