VLAN Trunking 2

Question 1

Explanation

The 802.1q frame format is same as 802.3. The only change is the addition of 4 bytes (32 bits) fields. That additional header includes a field with which to identify the VLAN number. Because inserting this header changes the frame, 802.1Q encapsulation forces a recalculation of the original FCS field in the Ethernet trailer.

Question 9

Explanation

The “switchport mode trunk” is the most important command to identify if a port is configured in access or trunk mode. In this case because of the “switchport mode trunk” command, the “switchport access vlan 700” does not have any effect.

There is no “switchport trunk native vlan …” command so it is using the default native VLAN, which is 1.
