Difficulty: MediumVLAN Configuration and Access Port Setup

A network administrator needs to manually configure interface GigabitEthernet1/0/22 on a Cisco Catalyst switch as a dedicated access port for a workstation in VLAN 35 (FINANCE). Assuming VLAN 35 already exists in the VLAN database, which set of commands must be applied under the interface configuration mode to properly complete this task?

  1. switchport mode access
    switchport access vlan 35    Answer
  2. B
    switchport mode trunk
    switchport trunk native vlan 35
  3. C
    switchport access vlan 35
    spanning-tree portfast trunk
  4. D
    vlan 35
    switchport mode access host

Answer

To configure a switch interface as a static access port in VLAN 35, the engineer must enter interface configuration mode and execute 'switchport mode access' followed by 'switchport access vlan 35'.
The correct command sequence requires defining the interface operational type as an access port using 'switchport mode access' and then binding the port to the specific VLAN ID using 'switchport access vlan 35'.

Step-by-Step Solution

1
Enter interface configuration mode
Navigates to the interface context using 'interface GigabitEthernet1/0/22'.
Configuration commands for port membership must be executed under the specific interface prompt.
2
Set administrative mode to access
Executes 'switchport mode access'.
Definitive host access operation disables DTP dynamic negotiation into trunking state.
3
Assign the access VLAN ID
Executes 'switchport access vlan 35'.
Maps untagged ingress frames from the connected device into VLAN 35.
