Implementing Cisco IP Switched Networks (CCNP SWITCH, legacy) — Question 92

What is the Ethernet frame size for 802.1Q?

Answer options

• A. 64
• B. 128
• C. 1518
• D. 1522

Correct answer: D

Explanation

The correct answer is D, 1522, as it includes the additional 4 bytes for the VLAN tag in the Ethernet frame size when 802.1Q is used. The other options either represent the minimum frame size or the standard frame size without VLAN tagging, making them incorrect in this context.
