Which devices can perform frame rewrite?

Frame rewriting is a process where the header information of a frame is modified as it passes through a device in a network. Layer 3 switches, which operate at the network layer, have the capability to rewrite frames. This includes changing the destination MAC address, VLAN information, and other header details necessary for proper routing and switching between different segments of a network.

Wireless LAN Controllers are also capable of performing frame rewrites. They manage multiple access points and can modify frames as they are sent to and from these access points, particularly in environments where mobility and seamless handoffs are required. By adjusting frames' details, these controllers help in maintaining connectivity and efficient traffic management as devices move across different access points.

In contrast, while Layer 2 switches indeed operate on frames, they do not perform any rewriting of frames in the same more complex manner as Layer 3 switches do. Their function is primarily to forward frames based on MAC address lookups. Access Points themselves primarily focus on providing wireless connectivity and may not engage in frame rewriting to the extent that Layer 3 switches and WLAN controllers do.

This context explains the capabilities necessary for frame rewriting, which is why Layer 3 switches in conjunction with Wireless LAN Controllers are the correct choices for this function.
