You are assigning VLANs to the ports of switch R1. What VLAN number value is an assigned to the default VLAN?
A.
VLAN 1003
B.
VLAN 1
C.
VLAN ON
D.
VLAN A
E.
VLAN 0
Explanation:
The default VLAN is VLAN 1. Although this VLAN can be modified, it can not be deleted from the switch. The following VLANs are on by default for all Cisco Catalyst switches:
VLAN 1 – Default VLAN
VLAN 1002 – Default FDDI VLAN
VLAN 1003 – Default Token Ring VLAN
VLAN 1004 – Default FDDI Net VLAN
VLAN 1005 – Default Token Ring Net VLAN
Incorrect Answers:
A: This is the default Token Ring VLAN that is installed in the switch IOS. It is seldom used.
C: ON is a VTP configuration mode, but is not a normal VLAN name.
D: Although any VLAN can be named VLAN A, it is not created by default.
E: Although in Cisco IOS the number 0 has significance (i.e. ethernet 0, console port 0, serial 0) in VLANs 1 is the default. VLAN 0 is an invalid VLAN and can not be used.
