02
Front
What characterizes an access port?
Back
An access port normally connects an end device and belongs to one VLAN. Frames on that link are sent untagged.
03
Front
How do you create VLAN 20 and optionally name it SALES?
Back
From global configuration mode, enter `vlan 20`, then use `name SALES` in VLAN configuration mode if a descriptive name is desired.
04
Front
How do you assign an end-device port to VLAN 20?
Back
Configure the interface with `switchport mode access`, then assign the intended VLAN with `switchport access vlan 20`.
05
Front
How many access VLANs can one access port belong to at once?
Back
An access port belongs to one access VLAN at a time.
06
Front
What Layer 2 communication is possible within one VLAN?
Back
Devices connected to access ports in the same VLAN can communicate at Layer 2 through the switch, subject to other controls.
07
Front
What is required for communication between different VLANs?
Back
Different VLANs are separate broadcast domains. Communication between them requires Layer 3 routing.
08
Front
What endpoint settings are not supplied by VLAN assignment?
Back
VLAN assignment alone does not configure a device's IP address, subnet, or default gateway.
09
Front
What does `show vlan brief` help verify?
Back
`show vlan brief` lists VLANs and, on typical access-port displays, their member ports.
10
Front
What port details does `show interfaces ... switchport` report?
Back
`show interfaces ... switchport` reports the port's administrative mode and access VLAN.
11
Front
What should you check if a configured VLAN is unavailable?
Back
Check that the VLAN appears and is active. VLAN propagation can depend on the platform and VTP setup; create it explicitly where required.
12
Front
How can you catch a wrong-port or wrong-VLAN assignment?
Back
Confirm the interface identifier and the access VLAN value, then verify the VLAN in `show vlan brief`.
