Which statement about Cisco Express Forwarding is true? It uses a fast cache that is maintained in a router data plane It maintains two tables in the data plane the FIB and adjacency table It makes forwarding decisions by a process that is scheduled through the IOS scheduler The CPU of a router becomes directly involved with packet-switching decisions.
Which two statements about Cisco Express Forwarding load balancing are true? (Choose two) Cisco Express Forwarding can load-balance over a maximum of two destinations It combines the source IP address subnet mask to create a hash for each destination Each hash maps directly to a single entry in the RIB Each hash maps directly to a single entry in the adjacency table It combines the source and destination IP addresses to create a hash for each destination.
How are the Cisco Express Forwarding table and the FIB related to each other? The FIB is used to populate the Cisco Express Forwarding table The Cisco Express Forwarding table allows route lookups to be forwarded to the route processor for processing before they are sent to the FIB There can be only one FIB but multiple Cisco Express Forwarding tables on IOS devices Cisco Express Forwarding uses a FIB to make IP destination prefix-based switching decisions.
What is the difference between a RIB and a FIB? The RIB is used to make IP source prefix-based switching decisions The FIB is where all IP routing information is stored The RIB maintains a mirror image of the FIB The FIB is populated based on RIB content.
How does the RIB differ from the FIB? The RIB includes many routes to the same destination prefix. The FIB contains only the best route. The FIB maintains network topologies and routing tables. The RIB is a list of routes to particular network destinations. The RIB is used to create network topologies and routing tables. The FIB is a list of routes to particular network destinations. The FIB includes many routes a single destination. The RIB is the best route to a single destination.
What is the difference between CEF and process switching? CEF processes packets that are too complex for process switching to manage. CEF is more CPU-intensive than process switching. CEF uses the FIB and the adjacency table to make forwarding decisions, whereas process switching punts each packet. Process switching is faster than CEF.
What are two differences between the RIB and the FIB? (Choose two) The FIB is derived from the data plane, and the RIB is derived from the FIB. The RIB is a database of routing prefixes, and the FIB is the information used to choose the egress interface for each packet. FIB is a database of routing prefixes, and the RIB is the information used to choose the egress interface for each packet. The FIB is derived from the control plane, and the RIB is derived from the FIB. The RIB is derived from the control plane, and the FIB is derived from the RIB.
