350-401 Architecture Practice Question
A network administrator is configuring a Cisco Catalyst switch to support a new VLAN 200 for a guest network. The administrator wants to ensure that VLAN 200 is created and active on the switch. Which command should be used?
⚠ Common exam trap
A common mix-up: candidates confuse VLAN creation with port assignment or SVI creation, assuming that assigning a port to a VLAN automatically creates it.

Correct answer & explanation
✓
vlan 200
To create a VLAN on a Cisco Catalyst switch, the 'vlan 200' command is used in global configuration mode. This command creates the VLAN and enters VLAN configuration mode, where additional parameters like name can be set. The VLAN is active by default. Other commands like 'switchport access vlan' assign ports to the VLAN but do not create it, and 'interface vlan' creates an SVI, not the VLAN itself.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
interface vlan 200
Why it's wrong here
The 'interface vlan 200' command creates a Switch Virtual Interface (SVI) for VLAN 200, but it does not create the VLAN itself. The SVI is used for routing or management, but the VLAN must be created separately using the 'vlan' command. Without the VLAN, the SVI will be down.
- ✗
vlan database
Why it's wrong here
The 'vlan database' command is used in older Cisco IOS switches to enter VLAN configuration mode, but it is deprecated in modern Catalyst switches. On current platforms, VLANs are created in global configuration mode using the 'vlan' command. Using 'vlan database' may not be supported or may require additional steps.
- ✓
vlan 200
Why this is correct
The 'vlan 200' command in global configuration mode creates VLAN 200 and enters VLAN configuration mode. This is the correct way to create a VLAN on a Cisco Catalyst switch. After entering this command, the VLAN is active by default unless it is shutdown. This command is essential for adding a new VLAN to the switch's VLAN database.
- ✗
switchport access vlan 200
Why it's wrong here
The 'switchport access vlan 200' command is used on an interface to assign that interface to VLAN 200, but it does not create the VLAN. If VLAN 200 does not exist, the command may be accepted but the VLAN will not be active until it is created. This command is for port assignment, not VLAN creation.
