Which statement is true regarding VLANs?

The accurate statement about VLANs is that VTP, or VLAN Trunking Protocol, is used to transmit VLAN information across switches that are part of a configured VTP domain. This enables a streamlined process for managing VLAN configurations and propagating information to multiple switches, ensuring consistency without requiring manual configuration on each individual switch.

When VTP is set up correctly, it allows for the central management of VLANs, which simplifies the administration in environments where multiple switches exist. This means that when you create, modify, or delete a VLAN on a switch configured as a VTP server, that information is automatically distributed to other switches in the same VTP domain configured as clients.

The other statements do not hold true in the context of VLANs and networking. For example, while some Cisco switches may come with predefined VLANs, the amount and specifics can depend largely on the model and configuration; thus, it can't be stated categorically that all Cisco switches operate with two VLANs by default. The functionality of VLANs is not restricted to purely Cisco equipment, allowing interoperability with devices from other vendors as well. Furthermore, while there are recommendations and best practices regarding the number of switches in a VTP domain, exceeding ten switches is not inherently problematic as per technology
