Which of the following usually provides reliable, real-time information without consuming network
or host resources?
A.
network-based IDS
B.
host-based IDS
C.
application-based IDS
D.
firewall-based IDS
Explanation:
“A network-based IDS has little negative affect on overall network performance, and because it is
deployed on a single-purpose system, it doesn’t adversely affect the performance of any other
computer.” Pg 34 Krutz: CISSP Prep Guide: Gold Edition.
little negative effect is still an effect technically it counts and also consume network resources (so it cannot be without consuming network resources) therefore either answer is wrong or this question itself is wrong
