You are the network administrator for a rapidly growing company with a 100BaseT network. Users have recently complained about slow file transfers. In a check of network traffic, you discover a high number of collisions. Which connectivity device would best reduce the number of collisions and provide for future growth?
- A.
Bridge
- B.
Repeater
- C.
Hub
- D.
Switch
- E.
Gateway

Router
Correct Answer
D. SwitchExplanation
A switch would best reduce the number of collisions and provide for future growth in this scenario. A switch is a connectivity device that operates at the data link layer of the OSI model and uses MAC addresses to forward data packets only to the intended recipient. Unlike a hub, which broadcasts data to all connected devices, a switch creates separate collision domains for each port, reducing the likelihood of collisions. Additionally, a switch can handle higher network traffic loads and provide better performance compared to a hub. Therefore, implementing a switch would help alleviate the issue of slow file transfers caused by collisions and support the company's future growth.Rate this question:

Buffering
- B.
Flow control
- C.
Sequencing
- D.
Acknowledgements
- E.
CRC
Correct Answer(s)
C. Sequencing
D. AcknowledgementsExplanation
Sequencing helps to detect lost packets by assigning a unique sequence number to each packet. When the receiver receives the packets, it can check if any packets are missing by comparing the received sequence numbers with the expected sequence numbers. If there is a gap in the sequence numbers, it indicates that some packets were lost. Acknowledgements also help in detecting lost packets by requiring the receiver to send an acknowledgment message back to the sender for each received packet. If the sender does not receive an acknowledgment for a particular packet, it can assume that the packet was lost.Rate this question:
