   On F5 BIG-IP, how is a VLAN configured to accept tagged traffic on an interface?

   • ABy assigning a self-IP address to the interface and setting the VLAN ID to 0.
   • BBy using the 'tmsh create net vlan' command with the 'untagged' parameter.
   • CBy setting the interface to 'access' mode and specifying the VLAN ID.
   • DBy creating a VLAN and enabling the 'Tagging' option on the associated interface or trunk.

   What is the purpose of VLAN tagging on an Ethernet network?

   • ATo compress the Ethernet frame so that more data can be sent per second.
   • BTo prioritize all tagged frames over untagged frames in the switch's queue.
   • CTo encrypt frames so that only authorized devices can read the payload.
   • DTo allow multiple VLANs to share the same physical link while keeping their traffic isolated.

   A BIG-IP is connected to a switch via a trunk. The switch's native VLAN is VLAN 10. The BIG-IP is configured with VLAN 10 as untagged and VLAN 20 as tagged. A packet arrives at the BIG-IP with no 802.1Q tag. Which VLAN will the BIG-IP associate this packet with?

   • AThe packet will be assigned to a random VLAN
   • BVLAN 20
   • CVLAN 10
   • DThe packet will be dropped

   An engineer is examining a switch port that connects to a BIG-IP VLAN. The port is configured as a trunk and the BIG-IP interface is configured for a tagged VLAN. Which statement correctly describes how the switch handles traffic on this port?

   • AThe switch drops all frames that do not carry the VLAN tag, including frames from the native VLAN.
   • BThe switch strips the 802.1Q tag from outgoing frames and expects incoming frames to be untagged.
   • CThe switch adds an 802.1Q tag to frames that are sent out the port and expects incoming frames to carry the same tag.
   • DThe switch forwards all frames untagged, relying on the BIG-IP to assign the correct VLAN based on the source MAC address.

   What is the primary difference between a tagged VLAN and an untagged VLAN on an Ethernet network?

   • ATagged VLANs are used only on access ports, while untagged VLANs are used only on trunk ports.
   • BTagged VLANs carry only management traffic, while untagged VLANs carry user data.
   • CTagged VLANs are always assigned a higher priority than untagged VLANs in the switch's forwarding table.
   • DTagged VLAN frames include a VLAN identifier in the Ethernet header, while untagged VLAN frames do not carry a VLAN identifier.
