A network administrator is troubleshooting a connectivity issue between two switches. The trunk link between the switches is up, but devices in VLAN 20 cannot communicate across the trunk. The administrator checks the trunk configuration and sees that the trunk is configured with `switchport trunk allowed vlan 10,30`. What is the most likely cause of the issue?

VLAN 20 is not allowed on the trunk.

The native VLAN mismatch is causing VLAN 20 traffic to be dropped.

VLAN 20 does not exist on the local switch.

How does a switch initially learn the MAC address of a device connected to one of its ports?

It reads the source MAC address of incoming frames on that port

It uses ARP to resolve the MAC address

It sends a query to the device asking for its MAC address

It receives the MAC address from the DHCP server

A network engineer is analyzing a packet capture and sees a frame with destination MAC address FF:FF:FF:FF:FF:FF. The frame is an ARP request. How will switches handle this frame?

The switch floods the frame out all ports in the VLAN except the ingress port.

The switch forwards the frame only to the router.

The switch forwards the frame to the port with the matching MAC address.

The switch drops the frame because broadcast frames are not forwarded.

A network administrator is planning VLAN numbering for a new office. They need to separate data, voice, and management traffic. Which VLAN numbering scheme is appropriate?

Use VLAN 1 for data, VLAN 2 for voice, and VLAN 3 for management.

Use VLAN 1002 for data, VLAN 1003 for voice, and VLAN 1004 for management.

Use VLAN 4095 for data, VLAN 4094 for voice, and VLAN 4093 for management.

Use VLAN 10 for data, VLAN 20 for voice, and VLAN 100 for management.
