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
✓
The connection from 203.0.113.5:8080
203.0.113.5 is from the documentation IP range (RFC 5737), which should not appear in real network traffic. This indicates potential spoofing or malicious activity. Options B and C are internal private IPs, which are expected. Option D is the normal HTTP listening service.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The connection from 203.0.113.5:8080
Why this is correct
Correct. The external IP from the documentation range connecting on port 8080 is unusual and potentially malicious, suggesting proxy or tunneling activity.
- ✗
The connection from 192.168.1.10:54321
Why it's wrong here
Incorrect. 192.168.1.10 is a private IP with a high ephemeral port, which is normal for a client connection.
- ✗
The connection from 10.0.2.50:44350
Why it's wrong here
Incorrect. 10.0.2.50 is internal and port 44350 is high, typical for client connections.
- ✗
The listening on 0.0.0.0:80
Why it's wrong here
Incorrect. Listening on port 80 is standard for a web server and not suspicious.
