Question：1
A CE router running EBGP with the MPLS VPN service provider’s PE router is not able to receive any BGP updates from the PE router, and the debug ip bgp updates on the CE router shows the following debug message. BGP(0): 150.1.11.18 rcv UPDATE about 150.1.12.16/28 — DENIED due to: AS-PATH contains our own AS
What can be configured on the PE router to solve this problem?
A: Configure the PE router as a route reflector with the CE router as one of its clients.
B: Configure AS-Path Prepending on the PE router.
C: Configure AS-Override on the PE router.
D: Configure AllowAS-In on the PE router.
E: Configure AllowAS-Out on the PE router.
Correct Answers: C
Question：2
Within an MPLS domain, which of the following has the most impact on network convergence time?
A: the LDP convergence time
B: the IGP convergence time
C: the IGP to MPLS redistribution process
D: the time required to rebuild the LIB table
E: the time required to cache the routing table entries into the FIB table
Correct Answers: B
Question：3
BGP is used as the CE-PE routing protocol in an MPLS VPN. The customer routes are successfully propagated from the CE router to the ingress PE router, but they are not showing up on the egress PE router. What is the most likely cause of the problem?
A: There is a BGP-to-MPBGP redistribution error on the ingress PE router.
B: There is a MPBGP-to-BGP redistribution error on the egress PE router.
C: One of the P routers is performing route summarization, breaking the path between the ingress and the egress PE routers into two LSPs.
D: RTs attached to the CE routes exported by the ingress router are not matched by at least one of the import RTs on the egress PE router.
E: A route reflector is used to propagate the routes from the ingress PE router to the egress PE router, thus breaking the LSP.
Correct Answers: D
Question：4
With MPLS VPNs, if the CE-PE routing protocol is BGP, which statement below is true?
A: The different customer sites must use different autonomous system numbers.
B: Manual route redistribution between EBGP and MP-BGP is required.
C: The SOO extended BGP community can be used to prevent routing loops.
D: A BGP virtual sham-link is required between the customer site’s CE routers to ensure optimal routing between the customer sites.
E: The customer’s autonomous system number must match the MPLS VPN service provider’s autonomous system number.
Correct Answers: C
Question：5
What are two concerns when implementing CEF switching? (Choose two.)
A:increased CPU utilization from maintaining the FIB table
B:increased memory requirement
C:the requirement to disable other IOS features such as NBAR and MQC
D:increased memory requirement on the VIP when implementing DCEF E:configuration complexity
F:troubleshooting complexity because of the many tables that CEF maintains
Correct Answers: B, D
