Answer options

• A. Access ports can only send untagged frames.
• B. Trunk ports can only send tagged frames.
• C. Access ports can only send tagged frames.
• D. Trunk ports can only send untagged frames.

Correct answer: B

Explanation

The correct answer is B because trunk ports are designed to carry multiple VLANs and therefore send tagged frames to identify the VLAN. Option A is incorrect because access ports send untagged frames. Option C is incorrect as access ports do not send tagged frames. Option D is also wrong since trunk ports do not only send untagged frames; they are meant for tagged traffic.
