Question 7: A service provider upgraded its core routers to CRS-1. The service provider connects the CRS-1 to an
internal network via CRS-1 management ports. This internal network is configured with private IP
addresses. All SSH access from a service provider workstation that is incoming to the management ports
of the CRS-1 routers was tested and was found to be working properly. The routers were configured for
AAA by using the Cisco Secure Access 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 in production, a need arose to
engage Cisco TAC to perform troubleshooting and diagnosis on the routers. It was noted that while all
service provider operations staff could access the routers from the private IP-based management network,
Cisco TAC could not access the router because its connection was coming in on the inband 10-Gigabit
Ethernet ports. The VTY line ACLs were configured to allow the Cisco TAC source IP address, 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.
Correct Answer: D
