- A
Ransomware
Why wrong: Ransomware typically encrypts files and demands payment, but does not usually establish a persistent C2 channel on port 4444 with outbound traffic.
- B
Botnet C2 client
Why wrong: A botnet C2 client could use port 4444, but the term is broader; however, a RAT is a specific type of malware that provides remote control.
- C
Remote Access Trojan (RAT)
RATs commonly use ports like 4444 for C2 communication, allowing remote control and data exfiltration.
- D
Keylogger
Why wrong: Keyloggers capture keystrokes and may exfiltrate data, but they do not typically cause high CPU usage or use port 4444 for C2.

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 350-701 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.
