The destination address field in a frame refers to the physical (or MAC) address of the destination node.
It will send the frame to all hosts except host A.This is a MAC broadcast address. All hosts on that subnet will receive the packet or frame. With the exception of the sending host of course.
The mode that looks at the destination address and immediately forwards the frame to the destination is called "cut-through switching." In this mode, the switch begins forwarding the frame as soon as it reads the destination MAC address, which reduces latency. However, it does not check the entire frame for errors before forwarding, which can lead to potential issues if the frame is corrupted.

Destination MAC address
The node sends out an ARP request with the destination IP address.
255.255.255.255
an address that begins with 01-00-5E in hexadecimal

The destination MAC is before the source one for easier scanning, mostly because it is the destination device that is important as that is the device we are trying to reach.
A switch floods a frame when it doesn't have the destination MAC address in its MAC address table. The frame is then forwarded out of all interfaces except the one it was received on in an attempt to find the correct host.
