A service provider offers video services on its DSL network. This service provider has multiple multicast-enabled edge routers that are connecting to its DSLAMs. Video is being delivered both as unicast and multicast. An operations engineer is faced with a troubleshooting scenario where the engineer wants to query a large number of edge routers to ensure that they have PIM neighbor relationship with upstream routers. The operations engineer also wants to check that one or more of the edge routers are IGMP queries on the interfaces that are connecting to DSLAMs. These tasks need to be accomplished without logging into each of the edge routers. Assume that the entire network is part of the same IGP and PIM topology.

Scenario:
Your company hosts a Voice Over IP (VoIP) service for its customers. Your Voice Operations center is responsible for all VoIP applications, including servers, gateways, and provisioning. The NOC is responsible for the network infrastructure, including LAN, WAN, Firewalls, and QoS.
Your Voice Operations Center started receiving calls in the early morning from customers who did NOT have dial tone and could NOT place or receive calls. The Operations Center was UNABLE to find any problems with their applications. At this point, they switched from the primary call manager to the secondary call manager to attempt to resolve the problem. This resolved the problem and customers had dial tone and were able to place and receive calls.
It is now after 8:00 AM and both the Voice Operations Center and NOC are fully staffed for peak activity hours. The tickets opened earlier are escalated and you are assigned to work with the Voice Operations Center to find and fix the problem. You review the trouble tickets and then join the scheduled teleconference to resolve the problem.
As a NOC member, which three troubleshooting steps should you perform from the network side to help isolate the problem? (Choose three.)
