What is the primary purpose of Bidirectional Forwarding Detection (BFD) in a network?

To perform path selection based on bandwidth and delay

To provide fast failure detection between adjacent forwarding engines

To encrypt data traffic between two routers

To replace routing protocols such as OSPF and BGP

Which of the following best describes how BFD operates?

It uses path-vector logic to prevent routing loops

It floods link-state advertisements to all routers in an area

It sends periodic control packets between two systems and declares a failure if packets are not received within a negotiated interval

It establishes TCP sessions to exchange routing information

What is the primary purpose of the Layer 3 MTU (Maximum Transmission Unit) in IP routing?

To limit the maximum number of hops a packet can traverse

To determine the bandwidth capacity of a network interface

To set the maximum number of concurrent TCP connections

To define the largest packet size that can be forwarded without fragmentation
