For devices to be members of a VLAN their network data frames must conform to the ____ ?
|
|
IEEE 802.1Q
|
|
|
IEEE 802.1D
|
|
|
IEEE 802.11
|
|
|
IEEE 802.11ax
|
Explanation:
Detailed explanation-1: -The 802.1Q tagging protocol allows the Ethernet frame size to increase by four bytes to a range of 68 to 1522 bytes. This size increase is due to the insertion of a four-byte VLAN tag into the frame. The tags, which include a VLAN Identifier (VID), are attached to each Ethernet frame by MAC address.
Detailed explanation-2: -Virtual local area networks, or VLANs, can be used to segment traffic within a network in combination with subnetting. VLANs keep traffic from different networks separated when traversing shared links and devices within a topology.
Detailed explanation-3: -VLAN Trunking (802.1Q) allows physical network interfaces in a computing environment to be shared, or multi-homed.
