Implementing Cisco Network Security (IINS, legacy) — Question 80

What are two challenges of using a network-based IPS? (Choose two.)

Answer options

• A. It requires additional storage and processor capacity on syslog servers
• B. As the network expands, it requires you to add more sensors
• C. It is unable to determine whether a detected attack was successful
• D. It must support multiple operating systems
• E. It is unable to detect attacks across the entire network

Correct answer: B, E

Explanation

The correct answers, B and E, highlight the challenges of scaling a network-based IPS and its limitations in monitoring. Option B is correct because as networks grow, additional sensors are necessary to maintain coverage. Option E is also correct as network-based IPS solutions may struggle to detect attacks across all segments of a large network, while the other options either pertain to different operational challenges or are not specific to the concept of network-based IPS.
