A switch that is configured to use the Spanning Tree Protocol will place a port in ____________ mode if sending traffic to it ma
Rashid [163]

Answer:

Blocking Mode    

Explanation:

Spanning Tree Protocol is used to allow path redundancy in the network without creating cycles/circles also called loops.

When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.

This affects the performance of the network as the result of broadcast packets flooding.

STP puts one port of the switch to forwarding mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to blocking mode and the one port that is left after this is placed in forward mode.

Spanning Tree Algorithm is used by STP to determine the optimal path  of switch to the network.

Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.

This information helps STP to eliminate the redundant paths.

So this is how STP allows only one active path to the destination while blocking all other paths to avoid switching loop.

What are some ways to accomplish full-duplex (FDX) digital communications on guided medium at the physical layer (OSI Layer 1)?
labwork [276]

Answer:

d. All of the above

Explanation:

Physical layer is the lowest layer of the OSI reference model that deals with the setup of physical connection to the network and with transmission and reception of signals.

Full duplex (FDx) is a bidirectional type of communication system where two end nodes send and receive data signals at the same time, and a single carrier is simultaneously used for dual communication.

To send or receive data, the participating nodes in a Full Duplex system do not have to wait for a free carrier/medium. It employs a medium that has at least two internal channels - one for sending and one for receiving.

Based on the above explanations, options A, B and C are valid and are correct ways to accomplish full-duplex (FDX) digital communications on guided medium at the physical layer (OSI Layer 1). There all of them are correct.
