from p. 256 of ODOM’s 100-105 text: “The example begins with the show vlan brief command, confirming the default settings of five nondeletable VLANs, with all interfaces assigned to VLAN 1. (VLAN 1 cannot be deleted, but can be used. VLANs 1002–1005 cannot be deleted and cannot be used as access VLANs today.) In particular, note that this 2960 switch has 24 Fast Ethernet ports (Fa0/1–Fa0/24) and two Gigabit Ethernet ports (Gi0/1 and Gi0/2), all of which are listed as being in VLAN 1 per that first command’s output.”
VLAN identifier (VID): a 12-bit field specifying the VLAN to which the frame belongs. The hexadecimal values of 0x000 and 0xFFF are reserved. All other values may be used as VLAN identifiers, allowing up to 4,094 VLANs. The reserved value 0x000 indicates that the frame does not carry a VLAN ID; in this case, the 802.1Q tag specifies only a priority and is referred to as a priority tag. On bridges, VID 0x001 (the default VLAN ID) is often reserved for a management VLAN; this is vendor-specific. The VID value 0xFFF is reserved for implementation use; it must not be configured or transmitted. 0xFFF can be used to indicate a wildcard match in management operations or filtering database entries.
According to cisco the answer of the reserved ones are 0 & 4095.
From cisco book Chapter: Understanding and Configuring VLANs
Vlan 0 and 4095 are the only reserved vlans

The answer is A! 1002 – 1005 are reserved for Token Ring and FDDI VLANs. {just sayian}

Answer is B
VLAN 0 is a default VLAN, for Cisco this is 1..
4095 is another reserved VLAN ID.
I mean Answer is not B, answer is A
Answer is B
A is default VLAN. But can be used however you want to configurate it.
1002 is reserved for a specified use right?
Prototype table
VLAN ID FUNCTION
VLAN 1002 Default FDDI VLAN
VLAN 1004 Default FDDI NET VLAN
VLAN 1005 (trbrf-default) with bridge number 0F Default Token Ring TrBRF VLAN
VLAN 1003 (trcrf-default) Default Token Ring TrCRF VLAN
Yes, answer is A.

Not A, yes to B
“reserved” is different permanent My bad
A
