- A
Photograph the scene including the screen, connections, and surrounding area
Documenting the scene is critical.
- B
Use a write blocker when connecting the suspect drive to a forensic workstation
Write blockers ensure the drive is not modified during acquisition.
- C
Attempt to recover deleted files using forensic software on the live system
Why wrong: This should be done later in a controlled environment, not by the first responder.
- D
Power off the computer immediately to prevent data modification
Why wrong: Powering off may lose volatile data; only do so if necessary and after capturing memory.
- E
Disconnect the computer from the network to stop remote access
Why wrong: While disconnecting may be appropriate, it is not a universal first step and may alter evidence.
CHFI Computer Forensics Fundamentals and Process Practice Question
This CHFI practice question tests your understanding of computer forensics fundamentals and process. 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 of the following are essential duties of a first responder at a digital crime scene? (Select two.)

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
Photograph the scene including the screen, connections, and surrounding area
First responders must secure the scene, document everything, preserve evidence, and avoid altering the system state. Photographing the scene and using a write blocker to image are correct; collecting volatile memory is a specialized task, not a first responder's primary duty, and powering off without capturing RAM is generally avoided.
Key principle: OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.

- ✗
Attempt to recover deleted files using forensic software on the live system
Why it's wrong here
This should be done later in a controlled environment, not by the first responder.
- ✗
Power off the computer immediately to prevent data modification
Why it's wrong here
Powering off may lose volatile data; only do so if necessary and after capturing memory.

Why it's wrong here
While disconnecting may be appropriate, it is not a universal first step and may alter evidence.
Common exam traps
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Detailed technical explanation
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.
Key takeaway
OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough.
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. OSPF neighbour adjacency depends on matching area, hello/dead timers, network type, and authentication — IP reachability alone is not enough. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
What to study next
Got this wrong? Here's your next step.
Review OSPF neighbour requirements — matching area type, hello and dead timers, network type, stub flags, and authentication. Study show ip ospf neighbor states (INIT, 2-WAY, FULL). Then practise related CHFI OSPF questions on adjacency and route selection.
