Though DNS primarily uses UDP, however, it uses TCP in some places. There is no automatic recovery if a DNS packet is missed. It's problematic if it does, how can it be fixed?

Explain a situation where a video file is being sent between two computers over an unsecured ftp connection and the TCP three-way handshake is being exploited.

DNS uses UDP instead of TCP. If a DNS packet is lost, there is no automatic recovery. Does this cause a problem, and if so, how is it solved

Why do HTTP, SMTP, and POP3 communicate using TCP instead than UDP?

FTP, on the other hand, requires verification that a file has been correctly transmitted to a client, but it does not give a built-in means to track this information. File Transfer Protocol (FTP) relies on the TCP/IP architecture's Transport layer to ensure that data is delivered.

Why do HTTP, SMTP, and POP3 communicate using TCP instead than UDP?

One advantage of a ROUTER is that it can choose the "best" route between networks when there is a choice. True False

Clarify the TCP congestion management mechanism and describe its operation.

FTP doesn't have a built-in method for tracking the progress of files that have been sent to clients. File Transfer Protocol (FTP) depends on a different protocol at the TCP/IP architecture's Transport layer to guarantee a successful transfer.

UDP or TCP services may be used by certain applications. Thus, how can a computer identify a packet's transport layer?
