Which action is taken by switch port enabled for PoE power classification override? If a monitored port exceeds the maximum administrative value for power, the port is shutdown and err- disabled. When a powered device begins drawing power from a PoE switch port, a syslog message is generated. As power usage on a PoE switch port is checked, data flow to the connected device is temporarily paused. If a switch determines that a device is using less than the minimum configured power, it assumes the device has failed and disconnects it.

How do TCP and UDP differ in the way they provide reliability for delivery of packets? TCP does not guarantee delivery or error checking to ensure that there is no corruption of data, UDP provides message acknowledgement and retransmits data if lost. TCP provides flow control to avoid overwhelming a receiver by sending too many packets at once, UDP sends packets to the receiver in a continuous stream without checking. TCP is a connectionless protocol that does not provide reliable delivery of data; UDP is a connection- oriented protocol that uses sequencing to provide reliable delivery. TCP uses windowing to deliver packets reliably; UDP provides reliable message transfer between hosts by establishing a three-way handshake.
