PBR is the process of altering the path of a packet, using criteria other than the standard routing criteria. Besides the standard protocols, PBR can be used to condition routers to consider different parameters for routing packets. PBR may consider application, transport, network, and link layer data information contained in the packet. PBR is often implemented using special rules which, when triggered, assign or mark the packet to a specific routing table with unique route entries. With PBR, packets may be redirected using any of the following: •Destination IP address •Destination TCP or UDP port numbers •Source IP address •Source TCP or UDP port numbers Correct Answer B
