CCNP Practice Question: Which two statements about VLAN configuration and…

Which two statements about VLAN configuration and verification are true? (Choose two.)

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

A VLAN can be created using the 'vlan vlan-id' command in global configuration mode.

The correct statements are A and B. Statement A is true because the 'vlan vlan-id' command in global configuration mode creates a VLAN. Statement B is true because 'show vlan brief' displays all VLANs, including reserved VLANs 1002-1005 (though they are not user-created). Statement C is false because VLAN 1 is a default VLAN and cannot be deleted. Statement D is false because the 'switchport access vlan' command does not automatically create the VLAN; the VLAN must already exist. Statement E is false because 'show interfaces trunk' displays trunking interfaces along with their allowed VLAN list and native VLAN, not solely the native VLAN.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • A VLAN can be created using the 'vlan vlan-id' command in global configuration mode.

    Why this is correct

    True. The 'vlan vlan-id' command in global configuration mode creates a VLAN.

  • The 'show vlan brief' command displays all VLANs, including the reserved VLANs 1002-1005.

    Why this is correct

    True. 'show vlan brief' displays all VLANs, including reserved VLANs 1002-1005.

  • VLAN 1 can be deleted from the switch.

    Why it's wrong here

    False. VLAN 1 is a default VLAN and cannot be deleted.

  • The 'switchport access vlan' command automatically creates the VLAN if it does not already exist.

    Why it's wrong here

    False. The 'switchport access vlan' command assigns a port to an existing VLAN; it does not create the VLAN automatically.

  • The 'show interfaces trunk' command shows only the trunking interfaces and their native VLAN.

    Why it's wrong here

    False. 'show interfaces trunk' shows more than just the native VLAN; it also shows the allowed VLAN list and other trunk parameters.
