A rollout plan from engineering has been sent to the NOC for deployment. Part of the plan involves a complex software upgrade to a network element. The method of procedure provided by engineering is nearly 100
individual steps long. Where do you expect to find backout procedures to be specified?

You are working in a service provider voice NOC supporting a national VoIP network. The network underwent a capacity expansion that added voice bearer trunks to a newly deployed media gateway. After the new trunks
were configured and placed into live service, the service desk began to receive complaints from end customers that their VoIP service is not working for certain calls. The service desk is unable to resolve the problem and
due to increasing troubles coming in, they escalate to you.
Assuming that all physical layer option settings are verified to match carrier-provided specifications, which action should you take to isolate the problem before escalating to the PSTN PTT carrier?

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.
