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
✓
Throughput capacity and latency impact under peak load
Inline IPS deployments require careful evaluation of throughput performance, latency impact, and fail-open/fail-closed hardware capabilities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Throughput capacity and latency impact under peak load
Why this is correct
Inline devices can become bottlenecks if throughput capacity is insufficient.
- ✓
Fail-open versus fail-closed hardware bypass behavior during power failure
Why this is correct
Engineers must determine whether the network should fail open or closed if the IPS crashes.
- ✗
Configuring the IPS to act as an authoritative DNS root server
Why it's wrong here
An IPS does not serve as an authoritative DNS root server.
- ✗
The physical cable color used for connection to the core switch
Why it's wrong here
Cable color has no operational security impact.
- ✓
Signature tuning to minimize false positives that could drop legitimate traffic
Why this is correct
Tuning is essential to prevent blocking legitimate business traffic.
