Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Examine the process list on the web server to identify the source of the connection
Why this is correct
Connecting the network flow to a specific process ID is essential for attribution.
- ✗
Reset the database server credentials
Why it's wrong here
This is a reactive step that does not confirm the cause of the lateral traffic.
- ✗
Block the web server access entirely
Why it's wrong here
This is a drastic containment measure before confirming the threat.
