QUESTION 16:
In frame-relay MPLS, where is the label imposed?
A. Between Layer 1 and Layer 2 headers.
B. Between Layer 2 and Layer 3 headers.
C. In the VPI/VCU fields.
D. In the VPI field alone.
Answer: B
Explanation:
MPLS labels are assigned to packets based on groupings or forwarding equivalency
classes (FECs) at the ingress eLSR. A FEC is a group of packets from a source IP address
that are all going to the same destination. The MPLS label is imposed between Layer 2
and Layer 3 headers in a frame-based packet environment, or in the Layer 2 virtual path
identifier/virtual channel identifier (VPI/VCI) field in cell-based networks like ATM.

QUESTION 17:
Network topology exhibit
Liberal label retention and unsolicited downstream distribution is being used in the
frame-mode MPLS network shown in the exhibit. The best to network X as defined
by the IGP for network is PassGuide 1- PassGuide 2- PassGuide 4- PassGuide 5.
What will Router PassGuide 3 and rout
A. Both routers will add it to their LIB.
B. Both routers will ignore it.
C. Router PassGuide 3 will add the label to its LIB. Router PassGuide 4 will ignore it.
D. Router PassGuide 4 will add the label to its LIB. Router PassGuide 3 will ignore it.
Answer: A
QUESTION 18:
What is true about the label in frame-mode MPLS?
A. 32 bit label with an 8 bit label field.
B. 32 bit label with a 20 bit label field.
C. 20 bit label with a 3 bit Bottom of Stack field.
D. 20 bit label with a 1 bit TTL field.
Answer: B
QUESTION 19:
Which two statements about TDP and LDP are true? (Choose two)
A. TDP and LDP populate the same LFIB.
B. TDP operates over UPD while LDP operates over TCP.
C. TDP and LDP both operate over TCP, but use different port numbers.
D. While TDP and LDP are functionally equivalent, they use a different label format.
Answer: A, C
Explanation:

According to the “Implementing Cisco MPLS” Student Guide (Text
Part Number: 97-1153-01) Volume 1, version 1.0, page 2-51.
TDP vs. LDP:
- MPLS and Tag switching are equal on the data plane ( for me it means that they
populate the same FIB and LFIB)
- The only difference is on the control plane, where tag switching uses Cisco proprietary
TDP and MPLS uses standard LDP
- TDP and LDP are functionally equivalent but not compatible
- TDP use UDP and TCP port number 711
- LDP uses UDP and TCP port number 646
Not D: LDP and TDP use the same label format.
QUESTION 20:
Which command should you use to display the contents of LFIB?
A. show tag routes
B. show tag tdp lfib
C. show tag bindings
D. show tag forwarding-table
Answer: D
