What is the minimum time gap required by the local system before putting a BFD control packet on the wire?
- A . Detect Mult
- B . Required Min Echo RX Interval
- C . Desired Min TX Interval
- D . Required Min RX Interval
C
Explanation:
Desired Min TX Interval: This is the minimum interval, in microseconds, that the local system would like to use when transmitting BFD Control packets, less any jitterapplied. The value zero is reserved.
Required Min Echo RX Interval: This is the minimum interval, in microseconds, between received BFD Echo packets that this system is capable of supporting, less anyjitter applied by the sender. If this value is zero, the transmitting system does not support the receipt of BFD Echo packets.

Which function does LDP provide in an MPLS topology?
- A . It enables a MPLS topology to connect multiple VPNs to P routers.
- B . It provides hop-by-hop forwarding in an MPLS topology for LSRs.
- C . It exchanges routes for MPLS VPNs across different VRFs.
- D . It provides a means for LSRs to exchange IP routes.
B
Explanation:
LDP provides a standard methodology for hop-by-hop, or dynamic label, distribution in an MPLS network by assigning labels to routes that have been chosen by the underlying Interior Gateway Protocol (IGP) routing protocols. The resulting labeled paths, called label switch paths (LSPs), forward label traffic across an MPLS backbone to particular destinations.
