B: FALSE
Correct Answer:
F; A. TRUE; L; S; E
Explanation

The statement is false because the valid range for VLAN IDs as defined by the IEEE 802.1Q standard is 0 to 4095. Within this range, VLAN IDs 1 through 4094 are available for general user configuration. VLAN ID 0 is used for priority tagging, and VLAN ID 4095 is reserved for protocol use. A VLAN ID of 4096 is outside the 12-bit field allocated for VLAN identification and is therefore invalid. A trunk interface can carry frames for multiple valid VLANs, but not for the non-existent VLAN 4096.

Why Incorrect

True: This option is incorrect because VLAN ID 4096 is not a valid identifier according to the IEEE 802.1Q standard. The maximum possible VLAN ID is 4095.
