Exam Number/Code : 642-691
Exam Name : CCIP BGP + MPLS Exam (BGP + MPLS)
Questions and Answers : 80 Q&As

Exam Description
The BGP+MPLS exam is the quickest way for currently certified CCIP (Cisco Certified Internetwork Professionals) to obtain recertification. The exam tests skills and knowledge pertaining to the Configuring BGP on Cisco Routers (BGP) and Implementing Cisco MPLS (MPLS) courses. BGP+MPLS may be taken to recertify your CCIP certification. It may also be taken in place of the BGP and MPLS exams required for the CCIP certification.
Exam Topics
The following information provides general guidelines for the content likely to be included on the BGP+MPLS Exam. However, other related topics may also appear on any specific delivery of the exam.

Technology
*Understand and explain Core MPLS technology and concepts
*Understand and explain MPLS VPN technology and concepts
*Understand and explain basic BGP concepts and operations
*Understand and explain how to Scale IGP and BGP in Service Provider Networks

Basic Implementation & Configuration
*Explain and implement Frame-mode MPLS operations on Cisco IOS Platforms
*Explain and implement Cell-mode MPLS operations on Cisco IOS Platforms
*Explain and implement BGP Route Selection Using Policy Controls on Cisco IOS Platforms
*Explain and implement BGP Route Selection Using BGP Attributes on Cisco IOS Platforms
*Explain and implement Customer-to-Provider Connectivity with BGP on Cisco IOS Platforms
*Explain and implement BGP Transit Autonomous System on Cisco IOS Platforms
*Explain and implement IBGP connectivity using BGP Route Reflectors on Cisco IOS Platforms
*Explain and implement BGP Confederations on Cisco IOS Platforms

Advanced Configuration
*Explain and implement Advanced BGP Configuration on Cisco IOS Platforms
*Explain and implement MPLS VPN operations on Cisco IOS Platforms
*Explain and implement OSPF inside an MPLS VPN

This is one of the main exams related to the BGP and the MPLS technology, Cisco’s router technology is used worldwide and hence this certification is your ticket to work worldwide. Think of it as a blessing, and this exam will further help you as well in further certifications. And this exam is the quickest way to get recertified about you CCIP certification.

Exam 642-691: Cisco BGP + MPLS Exam: counts as credit toward the following certification:

*Cisco Certified Internetwork Professional – CCIP

For this exam the candidate must be mentally prepared for the implementation and configuring tasks related to BGP on Cisco routers and MPLS. These training courses are also available and applicants should necessarily go through them before giving the paper. The next thing is the personal search that one should carry out on the implementation that is going on worldwide as that would broaden the perspective of the applicant and make it worth studying for.

networks, the LFIB can become too large and it may be necessary to limit the
maximum diameter of the MPLS LSPs.
B. Because downstream-on-demand label allocation uses hop count to control loop detection, it maybe
necessary to limit the maximum diameter of the MPLS network.
C. Because end-to-end delay can cause problems with some voice applications, it may be necessary to
limit the maximum diameter of the MPLS network.
D. When interconnecting large frame mode MPLS and cell mode networks it may be necessary to limit the
maximum network diameter to prevent forwarding loops.
Answer: B
2. Refer to the diagram. What problem can be caused by the second P router summarizing the loopback
address of the egress PE router?
A. The first P router will be faced with a VPN label which it does not understand.
B. The second P router will be faced with a VPN label which it does not understand.
C. The egress PE router will not be able to establish a label switch path (LSP) to the ingress PE router.
D. A label switch path (LSP) will be established from the ingress PE router to the egress PE router, an event
that is not desirable.
In a central services topology, which routes do client VRFs contain?
A. routes from the client site, but not from the server site
B. routes from the server site, but not from the client site
C. routes from both the client site and the server site
D. only EBGP routes from either the client site or the server site
Answer: C
4. On a dedicated subinterface implementation, PE-2 must establish an address-family vrf IPv4 BGP
neighbor relationship with which router?
A. CE-1
B. CE-2
C. PE-1
D. PE-IG
E. CE-1 and CE-2
F. PE-1 and PE-IG
of a peer-to-peer VPN using a shared provider edge (PE) router? (Choose
three.)
A. A full mesh of virtual circuits is required between the customer sites.
B. All the customers have to share a common IP address space.
C. Optimal routing between customer sites cannot be guaranteed.
D. The shared PE router has to know all routes for all customers.
E. Packet filters are required on the PE routers.
Answer: BDE
6.Which two of the following statements regarding LDP are true? (Choose two.)
A. LDP can also be used between nonadjacent routers using multicast LDP hello messages.
B. LDP does not require periodic hello messages once the LDP session has been established between the
LDP peers.
C. LDP hello messages use TCP packets with a destination port number of 646.
D. Multiple sessions can be established between a pair of LSRs if they use multiple label spaces.
E. Per-platform label space can be identified by a label space ID of 0 in the LDP identifier field.
