Exam 350-401 topic 1 question 19 discussion

Agree that C is the way more correct answer. "Punt" is often used to describe the action of moving a packet from the fast path (CEF) to the route processor for handling. Cisco Express Forwarding (CEF) provides the ability to switch packets through a device in a very quick and efficient way while also keeping the load on the router‘s processor low. CEF is made up of two different main components: the Forwarding Information Base (FIB) and the Adjacency Table. Process switching is the slowest switching methods (compared to fast switching and Cisco Express Forwarding) because it must find a destination in the routing table. Process switching must also construct a new Layer 2 frame header for every packet. With process switching, when a packet comes in, the scheduler calls a process that examines the routing table, determines which interface the packet should be switched to and then switches the packet. The problem is, this happens for the every packet.

C is correct

C Makes more sense

C obviously

"C" is correct. CEF uses line-card unlike process-switching that uses CPU for its decision-making.

C is correct

Answer is correct

C is correct

provided answer is correct

Process switching requires the CPU to be personally involved with every forwarding decision C is only correct answer

Provided answer is correct

cef is less cpu intenive than process switching

Process switching is much slower then cef
