• B. Assign the access port to a VLAN.
• C. Configure an IP route to the VLAN destination network.
• D. Connect the router to a trunk port.
• E. Configure full duplex.

Correct answer: B, D

Explanation

To implement router-on-a-stick, you must assign the access port to a VLAN (B) and connect the router to a trunk port (D) for proper traffic handling. The other options, while they may be relevant in different contexts, are not required for the basic setup of router-on-a-stick.
