Which of the following descriptions of the different classifications of PBR is correct?

Question

Options

• APBR can be divided into interface PBR, local PBR and routing PBR.
• BLocal PBR can only be used to process local services, not for forwarded packets.
• CInterface PBR can modify the IP-Precedence of IP packets
• DInterface PBR is called under the interface and takes effect on the outbound packets of the interface.

• A
  3% (1)
• B
  10% (3)
• C
  14% (4)
• D
  72% (21)

Explanation

Option D is correct because interface PBR is configured directly on a network interface and applies its routing policy to packets leaving (outbound on) that interface, overriding the standard routing table for matching traffic. Option A is wrong because PBR has only two standard classifications - interface PBR and local PBR - and "routing PBR" is not a recognized category. Option B is wrong because local PBR is specifically designed to handle packets that originate locally from the device itself (such as management or control-plane traffic), not forwarded traffic, so the statement misrepresents its role rather than correctly limiting it. Option C is wrong because interface PBR is used to redirect forwarding paths based on policy criteria; modifying IP-Precedence is a QoS marking function, not a capability of interface PBR.

Memory tip: Think of the two PBR types by their attachment point - interface PBR attaches to an interface and catches outbound packets, while local PBR attaches to the device itself and catches locally generated packets.
