Users have complained recently about their experience with a collaboration tool that is being used on different international locations on your network. The collaboration tool uses IP precedence of "4" for all the traffic that runs over your network. Upon investigating the problem, you noticed that the tool worked fine most of the time. You observed that video frames would freeze occasionally for a short time, and some collaboration features had slow responses. The IT department has been engaged, and they believe that the problem is with the network transport. You tried end-toend extended pings by using the ToS value of 128 and noticed a high round-trip time on some of the ping packets. To the best of your knowledge, all the routers in the forwarding path are distributed architecture, hardware-based forwarding devices, and the entire path is QoS-enabled.

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 troubleshooting strategy should you suggest to the Voice Operations Center to help them isolate the problem to the call manager server or network?

You are working at a service provider supporting the core network. While proactively monitoring syslog, you notice that two power supplies have failed on one of the core routers. The router has five power hot-swappable supplies in total. Three are required to be working to support the power draw of the router. At this point, the router is still functioning correctly. It is now several hours before peak traffic will be present on the network. The next safe time for performing physical maintenance is not until after the peak traffic window. Which two steps should you take to minimize network impact during peak traffic? (Choose two.)
