A. B. C. D. E.


Access ports are used to connect end devices, such as computers or servers, to the network. VLANs can be used to logically segment the network and isolate traffic. When a switch port is configured as an access port, it can be assigned to only one VLAN.

A data VLAN is a VLAN that carries user-generated traffic, such as web browsing, file transfers, and email. Here are the two statements about data VLANs on access ports that are true:

  1. Two or more VLANs can be configured on the interface. This statement is false. An access port can only be assigned to a single VLAN. If you want to carry traffic from multiple VLANs on an access port, you need to use a technique called VLAN tagging or trunking.

  2. They can be configured as host ports. This statement is true. An access port can be configured as a host port. This means that the switch port is connected to an end device, such as a computer or printer, and the device is not capable of understanding VLAN tags. The switch port will automatically assign untagged frames to the configured VLAN.

Option C is incorrect because it states that only one VLAN can be configured on the interface, which is correct. Option D is also incorrect because access ports are not configured as trunk ports. Option E is incorrect because 802.1Q encapsulation is only used on trunk ports to carry multiple VLANs over a single physical link.
