QUESTION 13

A service provider upgraded its core routers to CRS-1. The service provider connects the CRS-1 to an internalnetwork via CRS-1 management ports. This internal network is configured with private IP addresses. All SSHaccess from a service provider workstation that is incoming to the management ports of the CRS-1 routers wastested and was found to be working properly. The routers were configured for AAA by using the Cisco SecureAccess Control Server, and AAA was working as desired. Furthermore, SNMP traffic used the inband 10-Gigabit Ethernet ports, and all

SNMP functionality was properly configured and tested prior to the rollout. After CRS-1 routers were placed inproduction, a need arose to engage Cisco TAC to perform troubleshooting and diagnosis on the routers. It wasnoted that while all service provider operations staff could access the routers from the private IP-basedmanagement network, Cisco TAC could not access the router because its connection was coming in on theinband 10-Gigabit Ethernet ports. The VTY line ACLs were configured to allow the Cisco TAC source IPaddress, but that did not fix the problem.

What is a possible cause for the lack of connectivity? (Choose one.)

A. Local packet transport service is misconfigured.B. The Cisco IOS XR administration plane is misconfigured.C. The Cisco IOS XR IPv4 virtual address is not configured to be used as a source address.D. Management plane protection is misconfigured

QUESTION 38

Refer to the exhibit. The network diagram shows a video service provider. The IPTV video source is connectedto R1, whereas the clients are connected to R6. Traffic flows from R1 to R6 both as unicast as well asmulticast. Unicast traffic load is greater than multicast by several orders of magnitude. There are two pathsfrom R1 to R6, each of them traverses through the R3 router. The path R1-R2-R3-R6 has a lower OSPF costpath compared to R1-R5-R4-R3-R6. The service provider took into account several design criteria andimplemented TE tunnels with forwarding adjacency between R1 and R3 both from the perspective of loadsharing as well as for fast reroute. Bringing up TE tunnels had the affect of dropping multicast traffic at the R3router. On troubleshooting the issue, you noticed that the OSPF route to the source of multicast traffic wasbeing learned over the TE tunnel, and this has caused the RPF check to fail.

Considering this problem, what are two solutions to prevent multicast traffic from being affected by the RPFcheck failing due to the TE tunnel? (Choose two.)

A. Use multitopology routing if the software supports it.B. Create a static mroute on R3 with the RPF pointing to the TE tunnel.C. Use multicast-intact with forwarding adjacency.D. Enable PIM on the TE tunnel on both of the headend routers.E. Enable on the core facing links a new routing protocol such as another OSPF process or ISIS.F. Configure the TE tunnel to use autoroute announce as opposed to forwarding adjacency, and circumvent

the RPF problem by using the multicast-intact command.

QUESTION 55

Refer to the exhibit. The figure shows a service provider network that has MPLS TE tunnels that originate fromGSR1, GSR2, and GSR3. While GSR1 and GSR2 have multiple paths to the core network, the GSR3 has asingle path into the core. For GSR1 and GSR2, the purple links are the preferred paths, but because they aremultihomed to the core, they can also take the black, less- desirable path. The less-desirable black paths needto be retained for certain operational reasons. GSR3 has a single path into the core network, and a TE tunneloriginating from GSR3 must be able to use this path. It has been noted that if the network encounters multiplelink failures or link transitions, the TE tunnels originating from GSR1 or GSR2 can preempt the TE tunneloriginating from GSR3, thus causing a lack of MPLS connectivity. The operations team does not want the TEtunnel 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.
