Implementing Cisco Network Security (IINS, legacy) — Question 12

What is an advantage of placing an IPS on the inside of a network?

Answer options

• A. It can provide higher throughput
• B. It receives traffic that has already been filtered
• C. It receives every inbound packet

Correct answer:

Explanation

The correct answer is B, as placing an IPS inside the network allows it to analyze traffic that has already been filtered by perimeter defenses, thus improving its efficiency and effectiveness. Option A is incorrect because while it may improve throughput, that is not the primary advantage of internal placement. Option C is wrong because an IPS on the inside does not process every inbound packet, only the internal traffic that has passed through the external defenses.
