As a critical part of the design for the Enterprise Campus network， which of the following two aretrue concerning intrusion detection and prevention solution？ （）

A.IDS is capable of both inline and promiscuous monitoring， while IPS is only capable ofpromiscuous monitoring

B.IDS will stop malicious traffic from reaching its intended target for certain types of attacks.

C.IPS processes information on Layer 3 and 4 as well as analyzing the contents and payload ofthe packets for more sophisticated embedded attacks （Layers 3 to 7）

D.IPS inspects traffic statefully and needs to see both sides of the connection to function properly

E.IDS placement at the perimeter of Data Center outside the firewall generates many warningsthat have relatively low value because no action is likely to be taken on this information
