The load balancing modes at both ends of an Eth-Trunk can be different.

A.

TRUE

A.

TRUE

Answers
B.

FALSE

B.

FALSE

Answers
Suggested answer: A

Explanation:

Comprehensive It is possible for the load balancing modes at both ends of an Eth-Trunk (Ethernet Trunk) to be different, as long as the devices at both ends support the different modes. Load balancing modes control how traffic is distributed across multiple links in the trunk. Although the modes may differ, they must be compatible in terms of ensuring that traffic is appropriately handled across the multiple physical interfaces bundled in the trunk.

D.

If the configuration information changes, for example, the DNS server address changes, the administrator only needs to modify the configuration information on the DHCP server, facilitating unified management.

Answers
Suggested answer: A, C, D

Explanation:

Detailed

Using DHCP provides several advantages:

It helps prevent IP address conflicts because the DHCP server dynamically assigns IP addresses, ensuring each device gets a unique one.

IP addresses can be reused by setting lease times, allowing the DHCP server to recycle addresses from devices that no longer need them.

Centralized configuration management is also possible. If network configuration details such as the DNS server change, the administrator can update these settings on the DHCP server, and all DHCP clients will automatically receive the new information.
