QUESTION 41:
Certkiller uses a frame-mode MPLS WAN. Which three statements about
frame-mode MPLS are true? (Select three)
A. The MPLS data plane takes care of forwarding based on either destination addresses
or labels.
B. MPLS has three distinct components consisting of the data plane, the forwarding
plane, and the control plane.
C. Whenever a router receives a packet that should be CEF-switched, but the destination
is not in the FIB, the packet is dropped.
D. The CEF FIB table contains information about outgoing interfaces and their
corresponding Layer 2 header.
E. The control plane is a simple label-based forwarding engine that is independent of the
type of routing protocol or label exchange protocol.
F. To exchange labels, the control plane requires protocols such as Tag Distribution
Protocol (TDP) or MPLS Label Distribution Protocol (LDP).
G. None of the above
Answer: A, C, F
Explanation:
Label allocation and distribution in a Unicast IP routing network and MPLS
functionality, including label allocation and distribution, can be divided into these steps:
Step 1 The routers exchange information using standard or vendor-specific Interior
Gateway Protocol (IGP), such as Open Shortest Path First [OSPF], Intermediate
System-to-Intermediate System [IS-IS], and Enhanced Interior Gateway Routing
Protocol [EIGRP]).
Step 2 Local labels are generated. One locally unique label is assigned to each IP
destination found in the main routing table and stored in the Label Information Base
(LIB) table.
Step 3 Local labels are propagated to adjacent routers, where these labels might be used
as next-hop labels (stored in the Forwarding Information Base [FIB] and Label
Forwarding Information Base [LFIB] tables to enable label switching).
Step 4
Every label switch router (LSR) builds its LIB, LFIB, and FIB data structures based on
received labels.
These data structures contain label information:
1. The LIB, in the control plane, is the database used by Label Distribution Protocol
(LDP) where an IP prefix is assigned a locally significant label that is mapped to a
next-hop label that has been learned from a downstream neighbor.
2. The LFIB, in the data plane, is the database used to forward labeled packets. Local
labels, previously advertised to upstream neighbors, are mapped to next-hop labels,
previously received from downstream neighbors.
1. The FIB, in the data plane, is the database used to forward unlabeled IP packets. A
forwarded packet is labeled if a next-hop label is available for a specific destination IP
network. Otherwise, a forwarded packet is not labeled.
QUESTION 42:
You are responsible for managing and maintaining the Certkiller MPLS network.
What is the function of the MPLS data plane?
A. The data plane exchanges Layer 3 routing information using OSPF, EIGRP, IS-IS, and
BGP protocols.
B. The data plane exchanges labels using the label exchange protocols TDP, LDP, BGP,
and RSVP.
C. The data plane uses the Forwarding Information Base (FIB) to forward packets based
on the routing information.
D. The data plane uses Label Forwarding Information Base (LFIB) to forwards packets
based on the labels.
E. None of the above
