Implementing Cisco Network Security (IINS, legacy) — Question 83

Which two characteristics apply to an Intrusion Prevention System (IPS)? (Choose two.)

Answer options

• A. Does not add delay to the original traffic
• B. Cabled directly inline with the flow of the network traffic
• C. Can drop traffic based on a set of rules
• D. Cannot drop the packet on its own
• E. Runs in promiscuous mode

Correct answer: B, E

Explanation

Options B and E are correct because an IPS is typically placed inline to actively monitor and control network traffic, thus it runs in promiscuous mode. Option A is incorrect as while an IPS aims to minimize delay, it can introduce some latency, option C is misleading as it implies the IPS can drop traffic without being inline, and option D is false since an IPS can indeed drop packets on its own.
