What is the maximum number of VLANs that can be supported with one VLAN tag field?
A.
1024
B.
2048
C.
4096
D.
8192
The Answer Is:
C
This question includes an explanation.
Explanation:
In Ethernet networking, VLANs (Virtual Local Area Networks) are identified using a 12-bit VLAN ID field in the IEEE 802.1Q standard. Since 12 bits can represent 2¹² = 4096 unique values, the maximum number of VLANs that can be supported is 4096.
1024 and 2048: These values are less than the maximum and represent subsets of possible VLANs.
8192: This exceeds the 12-bit limit and is not supported by the standard.
