You are the only person who connects to the server, and you always use your Linux laptop for the connection. Your laptop supports both IPv4 and IPv6. The rest of your company network runs only IPv4. You need a cost-effective solution to allow your laptop to connect to the server. Your solution must also support communication through NAT servers.

Switch

A virtual LAN can be created using which of the following?

In-band management

Competes with normal network traffic for bandwidth, Must be encrypted to protect communications from sniffing, Affected by network outages

Computer A sends a normal frame. The first switch appends a VLAN ID to the frame. The second switch removes the VLAN ID before forwarding it to Computer B

Computers A and B are on the same VLAN and are separated by two switches. Computer A sends a frame to Computer B. Which of the following best describes the composition of the frame as it travels from A to B?
