IP Address Uniqueness on VLANIF Interfaces:Each VLANIF interface represents a different logical interface, often tied to distinct subnets. IP addresses for VLANIF interfaces must be unique on the same switch to prevent address conflicts and routing issues​​.

Correct Answer:TRUE. The IP addresses of VLANIF interfaces on the same switch must be different.

Detailed Explanation: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​​.

Trunk Interface Basics:

Trunk interfaces are used to carry traffic for multiple VLANs between switches.

Tagged frames include VLAN identifiers, while untagged frames belong to the native VLAN.

Untagged Frames:

Frames from the native VLAN are sent untagged on the trunk interface.

Conclusion:

Trunk interfaces support both tagged and untagged frames, so the statement is TRUE.
