Drag and Drop Questions
Drag the list of commands on the left to the proper command categories on the right.


Customer A is experiencing intermittent network performance problems. The SP NOC has determined that the “MPLS blackhole” is occurring during network convergence events. The suspected cause of the MPLS VPN traffic issue is that the customer’s IGP (OSPF) is converging faster than the LDP. What MPLS feature can be configured to eliminate the problem?

A.    Decrease the OSPF convergence timing (throttle timer)
B.    MPLS VRF protection feature
C.    MPLS fast reroute feature
D.    MPLS LDP Sync feature in OSPF
E.    Use Cisco MPLS Auto bandwidth Allocator

Answer: D

When MPLS VPN services are implemented, which CE-PE routing method does not require the use of the redistribute command to advertise customer routes between sites?

A.    Static routing
B.    RIP
D.    OSPF
E.    BGP

Answer: E

Refer to the exhibit. A service provider sees the following output indicating some problems. What are two possible causes? (Choose two)

A.    The router has not been configured with SSO
B.    The router has an inappropriately dimensioned policy feature card.
C.    The IGP timers of the router have been overturned
D.    The router has not been configured with MPLS TE automatic tunnels and fast Reroute
E.    The router has too many entries in its routing table

Answer: BE

You have configured a Layer 2 VPN circuit between two PE routers, PE1 and PE4. For some reason the VC circuit is not coming up. You checked the status and VC was down at both sides. After careful verification you have ruled out any Layer 2 VPN control plane configuration issues. Assuring that PE devices are running cisco IOS, what two additional troubleshooting steps should help identifying the problem? (Choose two)

A.    Show mpls forwarding-table for local circuit mismatch
B.    Show mpls 12transport hw-capability to check hardware capability
C.    show mpls l2transport binding to check for MTU
D.    Show MPL12transport binding to check VC labels
E.    ping mpls pseudowire to check MTU mismatches in the core

Answer: CE

What does this Cease Notification Syslog message indicate? May CET: % BGP-3-NOTIFICATION: received from neighbor 6/1 (cease) 0 bytes.

A.    The port is shut down
B.    The connection was rejected
