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
✓
Physical segmentation of the network (VLANs/VRFs).
Sensor placement must account for visibility, traffic volume, and policy enforcement needs.
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 number of users connected to the local office Wi-Fi.
Why it's wrong here
User count is less critical than traffic flow patterns.
- ✗
Local temperature of the server room.
Why it's wrong here
Environmental factors are secondary to network architecture requirements.
- ✓
Physical segmentation of the network (VLANs/VRFs).
Why this is correct
Sensors must have visibility into the relevant segments.
- ✓
Availability of mirror ports or TAP points for traffic inspection.
Why this is correct
Passive or inline placement requires appropriate physical connectivity.
- ✓
Traffic throughput capacity of the firewall hardware.
Why this is correct
Performance must match the traffic load to avoid latency.
