Which description of Management Plane Protection is true?

MPP's purpose is to prevent all interfaces from carrying management packets, specifically by allowing only designated interfaces to do so, thus restricting access.

MPP aims to protect the CPU by preventing unauthorized or excessive management packet floods from reaching it, not by allowing them.

Management Plane Protection (MPP) isolates management traffic to specific, designated secure interfaces, preventing unauthorized management access or attacks through other interfaces. This mechanism helps protect the device's CPU and management processes from malicious or excessive management packets originating from untrusted network segments.

While MPP secures management protocols by restricting ingress points, its primary function is interface restriction, not to guarantee support for all administrative management protocols.
