* A VLAN (virtual local area network) is a logical grouping of devices that share the same broadcast domain, regardless of their physical location or connection.
* VLANs can be used to separate different types of traffic on a network, such as data, voice, video, etc.
* VLANs can also improve network performance, security, and management by reducing the size of broadcast domains and limiting unnecessary traffic.
* To pass both data and telephony on an access port, the network engineer needs to configure the port as a trunk port, which can carry multiple VLANs using tags.
* The network engineer also needs to assign the data and voice devices to different VLANs, and enable quality of service (QoS) to prioritize the voice traffic over the data traffic.
* VoIP (voice over IP) is a technology that allows voice communication over an IP network, such as the Internet. VoIP is not a feature that can be configured on an access port, but rather a type of traffic that can be carried by a VLAN.
* VIP (virtual IP) is an IP address that is shared by multiple devices or servers, usually for load balancing or redundancy purposes. VIP is not a feature that can be configured on an access port, but rather a type of address that can be assigned to a device or server.
* VRRP (virtual router redundancy protocol) is a protocol that allows multiple routers to form a virtual router group and provide backup for each other in case of failure. VRRP is not a feature that can be configured on an access port, but rather a protocol that can be implemented on a router.
