QUESTION 47
A service provider allowed private IPv6 BGP peering with a university research network. On receiving IPv6 traffic, one Cisco 12000 Series Router that is located in the path of IPv6 traffic experienced high CPU use on its single-port OC192 line card that caused OSPF adjacency to drop on its port. Prior to receiving IPv6 traffic, this OC192 port was passing approximately 1 Gb of IPv4 traffic without any noticeable CPU use. What are two possible reasons for this performance problem? (Choose two.)
A. IPv6 neighbor discovery is enabled. It should be disabled on point-to-point links because this helps with CPU use.
B. IPv6 DAD is enabled. It should be disabled in the service provider core.
C. The line card is not capable of hardware forwarding of IPv6 traffic.
D. The line card has an old fabric loader and FPGA code.
E. Cisco Express Forwarding has been disabled on the line card.
F. Some of the IPv6 traffic contains extension headers causing increased CPU use.

QUESTION 55

Refer to the exhibit. The figure shows a service provider network that has MPLS TE tunnels that originate from GSR1, GSR2, and GSR3. While GSR1 and GSR2 have multiple paths to the core network, the GSR3 has a single path into the core. For GSR1 and GSR2, the purple links are the preferred paths, but because they are multihomed to the core, they can also take the black, less- desirable path. The less-desirable black paths need to be retained for certain operational reasons. GSR3 has a single path into the core network, and a TE tunnel originating from GSR3 must be able to use this path. It has been noted that if the network encounters multiple link failures or link transitions, the TE tunnels originating from GSR1 or GSR2 can preempt the TE tunnel originating from GSR3, thus causing a lack of MPLS connectivity. The operations team does not want the TE tunnel originating from GSR3 to be preempted unless this tunnel is administratively shut down.
How should this situation be mitigated?
A. Change TE config on GSR3 to include “priority 4 4.”
B. Change TE config on GSR3 to include “priority 6 4.”
C. Change TE config on GSR3 to include “priority 6 6.”
D. Use affinity and link coloring.
E. Use the “exclude” options on the explicit paths of GSR1 and GSR2.
F. Lower the signaled-bandwidth of the GSR3 TE tunnel.

Correct Answer: E

QUESTION 79
A large IPTV service provider primarily uses multicast for delivering IPTV services to its customers. The service provider delivers digital television channels to home viewers by using a set-top box as a home appliance and controls this device through its video middleware. Each video channel uses a unique multicast group address. Recently, some channels have higher channel change times; to alleviate this problem, a number of solutions were discussed between the operations and engineering groups. Adding to the complexity of the issue is the fact that the business has been growing, and the service provider made acquisitions both in its home operating market and new geographic locations. These changes have made the management of source and group addresses a major concern. The engineering team thinks that using static joins for popular channels at the edge routers and moving away from Sparse Mode to SSM-based forwarding will improve performance issues.
What are two valid concerns for the operations group? (Choose two.)
A. If SSM is used in the network, the operations team will need to use the rendezvous point for multicast monitoring.
B. Replacing a shared multicast tree with SSM offers no security or convergence advantage.
C. Using DNS-based SSM maps might not be possible.
D. A mix of static and dynamic joins will make troubleshooting difficult.
E. Provisioning and managing static joins can increase operational overhead
