200-901 Practice Question: An engineer wants to verify that a switch port is…
An engineer wants to verify that a switch port is configured as an access port in VLAN 10. Which command provides this information?
⚠ Common exam trap
Cisco often tests the distinction between commands that show operational status (like `show interfaces status`) versus those that show configuration (like `show running-config interface`), leading candidates to pick a command that only shows interface state rather than the actual VLAN assignment and port mode.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
show running-config interface
The `show running-config interface` command displays the current operational configuration of a specific interface, including whether it is configured as an access port and which VLAN it is assigned to. For a switch port in VLAN 10, the output will show `switchport mode access` and `switchport access vlan 10`, directly confirming the desired configuration.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
show running-config interface
Why this is correct
The running configuration shows each interface's explicit switchport mode and access VLAN assignment, directly confirming VLAN 10 membership. Operational commands such as show interfaces status or show vlan display derived state, but only the running configuration reveals the configured access port designation.
- ✗
show interfaces status
Why it's wrong here
'show interfaces status' reports link state, speed, duplex and VLAN assignment, but not the administrative mode (access versus trunk) configured on the port. It is tempting because it does display VLAN information. 'show running-config interface' or 'show interfaces switchport' reveals the access mode explicitly.
- ✗
show ip interface brief
Why it's wrong here
`show ip interface brief` lists interface IP addresses and up/down protocol states, so it reports no VLAN or switchport mode data. It is tempting because it quickly confirms Layer 3 addressing and interface status, which suits troubleshooting routed interfaces or checking whether a port is administratively up, not verifying VLAN 10 access membership.
- ✗
show vlan brief
Why it's wrong here
`show vlan brief` lists VLAN IDs, names, status and their assigned ports, but omits each port's administrative mode, so it cannot confirm access-mode configuration. It is tempting because it verifies VLAN 10 membership, and would be correct when checking which ports belong to a VLAN rather than how a specific port is configured.
