Regarding Policy Routing, the following description error is ?( Single choice questions).

The statement that a matched packet must be forwarded according to the policy-based route (PBR) is incorrect. If the next hop specified in the PBR policy is unreachable or the outbound interface is down, the router will not use the policy. Instead, it will ignore that PBR rule and fall back to forwarding the packet based on the destination IP address lookup in the main IP routing table (FIB). PBR provides a preferred path, not a guaranteed one under all network conditions.

A. This is a correct statement. When both next-hop and outbound interface are set, the interface takes precedence for load balancing.
B. This is a correct statement. Interface PBR is applied to traffic entering an interface to influence its forwarding decision.
C. This is a correct statement. Interface PBR affects transit traffic, while local PBR is required for traffic originating from the router itself.

1. Huawei HedEx Documentation, CloudEngine S12700 V200R019C10 Configuration Guide - IP Routing, Section: "PBR Configuration" -> "Overview of PBR". This section details that if the specified next hop in a PBR policy is unavailable, the system forwards packets according to the routing table.
