QUESTION 1
When implementing MPLS VPNs between CE and 642-066 PE routers, which of these statements is correct?
A. If using IS-IS as the PE-CE routing protocol, no redistribution is required.
B. If using static routes between the CE and PE routers, no redistribution of other VPN routes is required.
C. If the PE-CE protocol is not BGP, redistribution of other VPN routes from MP-BGP is required.
D. If RIP is the routing protocol that is used between the PE-CE routers, no redistribution is required, but any other protocol will require redistribution.
E. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protocol or static route will require redistribution.
Answer: C

QUESTION 2
You would like to log messages up to the severity level “Notification.” Which three of these commands will you need to issue in order to enable syslog messages to be sent to the syslog server at the 642-066 IP address 10.1.5.5? (Choose three.)
A. logging on
B. logging host 10.1.5.5
C. logging trap notifications
D. logging syslog notifications
E. logging monitor notifications
F. logging console notifications
Answer: ABC

QUESTION 3
While your MPLS core is using Cisco routers, the core of a company you have acquired is not. After extending your MPLS VPN networks by integrating the cores, you discover that the end-to-end LPS path between PE routers cannot be established.
Which of the following may have caused this problem?
A. the MTUs do not match
B. the BGP protocol versions do not match
C. MPLS is not supported between different vendors
D. MP-BGP is not supported between different vendors
E. you are using Cisco proprietary TDP in your existing core
Answer: E

QUESTION 4
You are troubleshooting an issue which is causing full-sized packets entering the MPLS cloud to be dropped. You have discovered that one of the switches in the MPLS core is not a Cisco 642-066 switch, but otherwise the MPLS MTU size is set to 1508 bytes on the routers. Based on this information, which ofthese may be the reason the packets are being dropped?
A. no switches support oversized packets
B. by definition, the maximum MTU is 1500 bytes
C. the switch on your MPLS core that was not produced by Cisco does not support oversized packets
D. in this situation, the MTU setting is irrelevant; in MPLS the maximum acceptable IP packet size is 1492 bytes
E. as MPLS VPN labeling increases the size of the packet by 8 bytes, the IP MTU should have been changed to 1508
Answer: C

QUESTION 5
Refer to the exhibit. Which two of these events will be the 642-066 result of issuing the above command? (Choose two.)

A. A 64-bit IPv4 prefix will be created.
B. The route distinguisher will be used to indicate VPN membership.
C. Extended BGP communities will be used to encode route distinguishers.
D. A 96-bit VPNv4 prefix will be created and propagated across the IP network.
E. The route distinguisher is 64 bits and will be prepended to an existing IPv4 route to make it globally unique.
Answer: DE
