CND Network Perimeter Protection Practice Question
Which TWO of the following deployment scenarios or features are commonly associated with Network Intrusion Prevention Systems (NIPS)? (Choose two)
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
✓
Inline placement directly in the path of network traffic flow to allow active packet dropping.
NIPS devices are placed inline to inspect traffic in real-time and can actively drop or block malicious packets before they reach internal targets.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Inline placement directly in the path of network traffic flow to allow active packet dropping.
Why this is correct
True. NIPS must be placed inline to actively prevent attacks by dropping malicious packets.
- ✗
Passive monitoring connected exclusively to a network switch SPAN port or test access point (TAP).
Why it's wrong here
False. Passive monitoring via a SPAN port is characteristic of IDS (NIDS), not IPS (NIPS), since a passive device cannot block live traffic.
- ✗
Operating purely as a Layer 2 bridge without inspecting any network-layer or transport-layer headers.
Why it's wrong here
False. NIPS devices inspect layers 3 through 7 to identify attack signatures and malicious behaviors.
- ✗
Generating syslog alerts for administrative review without affecting the delivery of network traffic packets.
Why it's wrong here
False. Generating alerts without affecting traffic describes a passive detection system (IDS).
- ✓
The ability to reset active TCP connections using TCP reset (RST) injections when malicious payloads are detected.
Why this is correct
True. NIPS can inject TCP RST packets to tear down active malicious sessions.
