BGP synchronization has been enabled.
What is the default severity level of syslog trap messages?
A Catalyst switch has just been installed and configured, and is not working as expected. You have decided to capture multiple show command outputs to study. Which one command could you use that includes the output of many other show commands, such as show version and show running-config?

deterministic response to all failures
no single point of failure
You are working with a client to deploy QoS on their Frame Relay WAN. They would like to be able to allow packets to cross the Frame Relay WAN but have them marked as discard eligible if they exceed the QoS policy. How would you accomplish this task?

In MPLS networks, what is the benefit of disabling TTL propagation?
to hide visibility to the core (provider) routers in the MPLS network
While troubleshooting a network outage, you discover that an employee brought a switch from home into the office to connect additional equipment to the network. In order to increase his speed, he connected this switch to both network ports in his office, resulting in a bridge loop. Which of these can you implement to prevent future occurrences of this issue?
Why is it appropriate to use conditional label advertising when deploying MPLS?
To restrict label switching to a limited number of networks
Which command retrieves and displays information about each Cisco product in the form of a UDI?
How does NTP help you troubleshoot network problems?
By setting all network devices to the correct time
What are four advantages to using tunnel brokers in an IPv6 transition environment? (Choose four.)

IPv6 enabling a node looks automatic to the end user.
Tunnel information is sent via IPv4.
Tunnel brokers make it simpler for nontechnical users to deploy manual tunnels.
