Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Server uptime count
Why it's wrong here
Uptime is a system metric and irrelevant to attack source identification.
- ✓
X-Forwarded-For header
Why this is correct
This header contains the original client IP address.
- ✗
Local time of the web server
Why it's wrong here
While important for timing, it is not an identifier for the source of the attack.
- ✗
The load balancer's internal management port
Why it's wrong here
This port is for administrative control, not traffic analysis.
- ✓
Original Request-URI
Why this is correct
The URI shows exactly what the client requested before any load balancer re-writes.
