This 220-1102 practice question tests your understanding of the company firewall logs show repeated…. 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.
The company firewall logs show repeated connection attempts from a single external IP address to TCP port 3389 on several internal workstations over the past hour. The workstations all have Remote Desktop enabled for administrative purposes. Which of the following is the MOST effective immediate action to mitigate this threat?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
B
Correct. Blocking the specific IP at the firewall immediately stops the brute-force attempts without affecting other services.
B
Distractor review
A
Disabling Remote Desktop entirely would prevent the attacks but also disrupt legitimate remote administration and requires configuration on each machine.
C
Distractor review
C
Windows Defender does not block network-level attacks on specific ports; it is antivirus/antimalware.
D
Distractor review
D
Requiring VPN for remote access is a best practice but does not immediately stop the current attack from the malicious IP.

Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this 220-1102 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: B — Port 3389 is used by Remote Desktop Protocol (RDP). Blocking the attacking IP address at the firewall will immediately stop the connection attempts from that source. Disabling Remote Desktop on all workstations is a valid long-term solution but requires more time and could impact legitimate administrative access. Enabling Windows Defender is unrelated. Requiring VPN would add a layer of security but does not address the immediate attack from that specific IP.
What should I do if I get this 220-1102 question wrong?
Identify which 220-1102 exam domain this question belongs to, then review the specific concept being tested. Practise related questions in that domain and focus on understanding why each wrong answer is tempting — not just why the correct answer is right.
