- A
Run a full antivirus scan on the affected workstation.
Why wrong: Running a scan without isolating the system first could allow the ransomware to continue encrypting files and communicating with its command server.
- B
Disconnect the workstation from the network immediately.
Disconnecting the network cable or disabling the wireless adapter stops the ransomware from spreading and communicating externally, containing the incident.
- C
Back up all files to an external drive before taking action.
Why wrong: Backing up during an active ransomware infection could result in backing up encrypted files, and the ransomware may also infect the external drive.
- D
Restart the computer and boot into Safe Mode.
Why wrong: While Safe Mode is useful later, the first step must be to disconnect from the network to prevent further spread.
Quick Answer
The correct first step is to disconnect the workstation from the network immediately. This action is critical because ransomware often spreads laterally across a network, encrypting files on connected drives and servers; isolating the machine cuts off its ability to communicate with other systems, containing the threat before it can propagate. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of incident response procedures, specifically the priority of containment over eradication or recovery. A common trap is to first run an antivirus scan or shut down the computer, but scanning can trigger further encryption, and shutdown may destroy volatile evidence. Remember the memory tip: “Cut the cord before you record”—disconnect the network cable before documenting or analyzing the infection.

Correct answer & explanation
Disconnect the workstation from the network immediately.
The immediate priority is containment to prevent the ransomware from spreading to other systems on the network. Isolating the workstation by disconnecting it from the network is the first step, followed by notifying the security team.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Detailed technical explanation
How to think about this question
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 220-1202 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.
