78. Which of the following configurations is used to logically aggregate computers that are physically connected to the same network?

Answer: C

Explanation:

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

A VLAN (Virtual Local Area Network) allows multiple computers on the same physical network to be grouped together logically, enabling more efficient management and increased security.

A) VLAN

This option correctly identifies the technology used for logically grouping devices on the same physical network. VLANs create distinct broadcast domains, which can enhance network performance and security by isolating traffic.

B) VPN

A VPN (Virtual Private Network) is used to create a secure connection over the internet, allowing remote users to access a private network. It does not aggregate computers on the same physical network but rather connects different networks or devices securely across the internet.

C) VLAN

This option is identical to Option A and correctly describes the function of VLANs in logically aggregating devices on the same physical network. Its repeated presence emphasizes the critical role of VLANs in network management.

D) MARI

MARI does not represent a recognized networking standard or technology related to the aggregation of computers on a network. It is irrelevant to the context of the question concerning network configurations.

Conclusion

The correct answer is VLAN, as it effectively allows for the logical grouping of computers on the same physical network, enhancing management, performance, and security. The other options either describe different technologies or are not applicable, failing to address the specific requirement of logically aggregating devices.
