  1. What is the purpose of a VLAN in a switched network?

    Answer: To logically segment network traffic into separate broadcast domains

    VLANs logically segment a switched network into separate broadcast domains, improving security and reducing unnecessary traffic.

  2. Which VLAN ID is the default VLAN on most Aruba switches?

    Answer: VLAN 1

    VLAN 1 is the default VLAN on most Aruba switches and is pre-configured on all ports unless changed by an administrator.

  3. What is the difference between an access port and a trunk port on an Aruba switch?

    Answer: Access ports carry one VLAN; trunk ports carry multiple VLANs

    Access ports are configured for a single VLAN for end-device connectivity, while trunk ports carry multiple VLANs between switches or uplinks.

  4. Which IEEE standard defines VLAN tagging on trunk links?

    Answer: IEEE 802.1Q

    IEEE 802.1Q is the standard that defines VLAN tagging, adding a 4-byte tag to Ethernet frames to identify which VLAN they belong to.

  5. What is a native VLAN on an 802.1Q trunk port?

    Answer: The VLAN whose traffic is sent untagged across the trunk

    The native VLAN on an 802.1Q trunk is the VLAN whose frames are transmitted without a VLAN tag, typically VLAN 1 by default.

  6. On an Aruba CX switch, which command displays the VLAN database?

    Answer: show vlan

    The show vlan command on Aruba CX switches displays all configured VLANs and their associated port memberships.
