How many bytes is the size of a 802.1Q tag?Question 1Select one:8 bytes8 bits4 bits4 bytes

Break Down the Problem

1. Identify the size of an 802.1Q tag in terms of bits and bytes.
2. Understand the options provided in the question.

Relevant Concepts

• An 802.1Q tag is an Ethernet frame tagging protocol that adds a header to the Ethernet frame.
• The size of the 802.1Q tag is standardized.

Analysis and Detail

1. The size of the 802.1Q tag is fixed at 4 bytes.
2. To convert bytes to bits:
   • 1 byte = 8 bits
   • Therefore, 4 bytes = $4 \times 8 = 32$ bits.

Verify and Summarize

The only option that corresponds to the size of an 802.1Q tag is 4 bytes, as it is the correct representation of its size.

Final Answer

4 bytes
