B. Dynamic Routing Protocol
C. IRDP
D. VRRP

5. When implementing MPLS VPNs between CE and 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, bu
other protocol will require redistribution.
E. If using OSPF or EIGRP as the PE-CE routing protocol, redistribution is not required, but any other protoc
static route will require redistribution.
Answer: C
6. You would like to log messages up to the severity level “Notification.” Which three of these commands will you

8. 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?

Answer: E

9. 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 switch, but otherwise the MPLS
MTU size is set to 1508 bytes on the routers. Based on this information, which of these 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
10. Cisco Catalyst switches support which three PVLAN port types? (Choose three.)
