Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Directly on the public ISP router
Why it's wrong here
This limits visibility to only traffic entering/exiting the gateway.
- ✗
Inside the isolated guest Wi-Fi network
Why it's wrong here
This provides no visibility into production server traffic.
- ✓
On a Span Port of the core distribution switch
Why this is correct
This allows monitoring of internal and external traffic flows.
- ✗
On the WAN interface of the firewall
Why it's wrong here
Traffic at this point is often encrypted or limited by firewall rules already.
