Question 78

VLAN is used to logically aggregate computers that are physically connected to the same network.

VLAN (Virtual Local Area Network) enables the grouping of devices on the same physical network into logical segments, allowing for improved management, security, and performance.

A) VLAN

This option is correct as VLANs are specifically designed to create logical groupings of devices within the same physical network, facilitating better organization and communication among devices that may not be on the same physical segment.

B) VPN

VPN (Virtual Private Network) is not used for aggregating computers within the same network; rather, it creates a secure connection over the internet between a user and a remote network, allowing access to resources as if they were on the same local network.

C) VLAN

This option is also correct, reiterating that VLANs are employed to logically segment and aggregate devices on the same physical network. It emphasizes the importance of this configuration in network management.

D) MARI

MARI does not correspond to any known network configuration related to logical aggregation of computers. Thus, this option is incorrect and does not apply to the context of the question.

Conclusion

The correct answer, VLAN, is essential for logically grouping devices within the same physical network, enhancing management and security. Both instances of VLAN highlight its relevance, while VPN and MARI do not fulfill the criteria set by the question, confirming their incorrectness.
