Difficulty: MediumVLAN Configuration and Access Port Setup

A network technician is configuring interface GigabitEthernet0/3 on a Cisco Catalyst switch to connect an end-user workstation to VLAN 25. Which TWO commands must be executed within interface configuration mode to properly set up this access port? (Select two.)

  1. switchport mode accessAnswer
  2. switchport access vlan 25Answer
  3. C
    switchport trunk native vlan 25
  4. D
    vlan 25

Answer

To configure an interface as a static access port in VLAN 25, the engineer must enter interface configuration mode and execute both 'switchport mode access' and 'switchport access vlan 25'.
Configuring a host-facing access port requires setting the operational mode to static access using 'switchport mode access' and assigning the desired broadcast domain membership using 'switchport access vlan 25'. Both commands must be executed under interface configuration mode.

Step-by-Step Solution

1
Set the switchport mode to access
Interface is hardcoded to operate as an access port rather than negotiating a trunk connection.
Security and operational best practices require explicitly setting access mode on host-facing ports.
2
Associate the access port with VLAN 25
Traffic on the interface is assigned to broadcast domain VLAN 25.
The command 'switchport access vlan 25' binds the port membership to VLAN 25.
