How do UTP and STP cables compare?
STP cables are cheaper to procure and easier to install and UTP cables are more expensive and harder to install.

Which configuration on the NewSwitch side of the link meets these requirements?
A client experiences slow throughput from a server that is directly connected to the core switch in a data center. A network engineer finds minimal latency on connections to the server, but data transfers are unreliable, and the output of the show Interfaces counters errors command shows a high FCS-Err count on the interface that is connected to the server. What is the cause of the throughput issue?
high bandwidth usage
a physical cable fault
a speed mismatch
a cable that is too long
What is the purpose of classifying network traffic in QoS?
services traffic according to its class
identifies the type of traffic that will receive a particular treatment
writes the class identifier of a packet to a dedicated field in the packet header
configures traffic-matching rules on network devices
