If an ips identifies an attack, it can a. drop the attack packet(s) b. allow all traffic packet(s) c. limit suspicious traffic to a certain percentage of the total bandwidth d. limit suspicious traffic to a certain percentage of the total bandwidth and drop the attack packet(s)

a. drop the attack packet(s)

Explanation:

An IPS not only detects and alerts system administrators but it also stops attacks. It is built to consistently monitor a network, report malicious incidents and take preventative actions. So, how does an IPS work exactly? An IPS does a deep packet inspection and either blocks the IP of whoever sent the malicious packet or removes the malicious packet's content and repackages its payloads. Thus, this means that the malicious packet is completely dropped by stripping off of its header information and any infected items in the packet.
