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
