Exam Description
The MPLS exam is a qualifying exam for the CCIP certification (Cisco Certified Internetwork Professional). The 642-611 MPLS exam will test materials covered under the Implementing Cisco MPLS course. The exam will certify that the successful candidate has knowledge and skills necessary to gather information from the technology basics to some of the more updated features and functions such as Traffic Engineering, Fast Reroute and any Transport over MPLS (AToM). The exam covers topics on MPLS Concepts, MPLS Label Assignment and Distribution, Frame-Mode/Cell-Mode MPLS Implementation on Cisco IOS Platforms, MPLS Virtual Private Networks Technology, MPLS VPN Implementation, Complex MPLS VPNs, and Internet Access from a MPLS VPN.

Exam Topics
The following information provides general guidelines for the content likely to be included on the exam. However, other related topics may also appear on any specific delivery of the exam.

QUESTION 27:
Why would you explicitly define the VPI/VCI when deploying cell-mode MPLS?
A. To reduce the number of labels required.
B. Because cell-mode MPLS only runs over defined VPI/VCIs.
C. To ease a migration by connecting an MPLS-enabled ATM network to the old ATM
network.
D. Because MPLS is needed and parts of the private network cross a non-MPLS aware
network.
Answer: A
Explanation:
A is the only possible answer. A technique (VC merge)
actually exists to help reduce the number of labels (and thus VC) created.
by mapping multiple incoming label values to a specific outgoing label,
the number of VCs can be reduced. of course i am not sure the meaning of the
word “explicitly” since VC merge seem to do all the mapping automatically.
Incorrect Answers:
B: B is false, as the reference states …with some hardware platforms
supporting only approximately 1000 VCs. The very small number of VCs
supported over an ATM interface makes these circuits a scarce resource that
must be tightly controlled. if 1000 is only a small number, and if optionB
is true, then according to the question, all 1000 VCs must be explicitly
defined. which is not possible, so we may “assume” that VCs can be
dynamically assigned.
C: C doesn’t seem to be correct. Explictily defining VCs require careful
designs.
D: Option D is wrong, since a LSP requires all
devices to be able to distribute labels, if non-MPLS aware switches are
used, they cannot fulfill the downstream-on-demand feature. in this
situation, only Frame (but not Cell) mode can be used.
QUESTION 28:
Which two statements about cell-mode MPLS loop prevention mechanisms are true?
(Choose two)
A. MPLS relies on the loop prevention mechanism MP-BGPB.
Loop detection algorithms in LDP ensure that loops are not present.
C. MPLS relies on the loop prevention mechanisms embedded in the IGP.
D. MPLS labels contain a Time-To-Live (TTL) field that prevents packets from looping
indefinitely.
Answer: B, D
Explanation:
Not A: A is not correct too since running cell mode MPLS doesn’t require neither MPLS
VPN nor MP-iBGP.
Not C: C is not correct as ATM switches cannot run IGP.
QUESTION 29:
Exhibit
Study the exhibit which displays an MPLS cell-mode network that is using default
label distribution.
When the label request for Network X is sent from router Certkiller A to the
MPLS-enabled ATM Switch Certkiller C, which if the following statements are true?
A. The MPLS-enabled ATM switch Certkiller C will reply with the local label if it already
has the next-hop label. Or it will not reply with the local label if it does not have the
next-hop label and it will forward the label request to the MPLS-enabled ATM Switch
Certkiller D.
B. The MPLS-enabled ATM switch Certkiller C will reply with the local label then it will
send its own label request to MPLS-enabled switch Certkiller D.
C. Since MPLS-enabled ATM Switch Certkiller C cannot perform IP routing lookup, it
will forward the label request to router Certkiller E (an ATM edge LSR) and Router
Certkiller E will then reply with its local label to Router CertkillerA (also an ATM edge
LSR).
D. Since the MPLS-enabled ATM Switch Certkiller C cannot perform IP routing lookup,
it will reject the label request from Certkiller A.
Answer: A
