Answer:
The MSS is 1455
Explanation:
MSS or maximum segment size is the total number of data transferred minus the TCP and IP header. The total number of transmitted frames in a switch network is between 64 bytes to 1518 bytes with a header and trailer. The MSS does not exclude this data-link layer effect but only the transport layer like TCP and UDP, and IP address header, unlike the mtu (maximum transfer unit) which involves all headers.
