Refer to the exhibit. How will data files get retrieved from the server? The client establishes a two-way connection to the server on port 21 for file transfer. From the perspective of computer A, port 21 is used to signal a push to the server, and port 20 is used to signal a pull from the server. There is a connection established to send files from the client to the server and a second connection to get files from the server to the client. Computer A establishes a connection to the server on port 21 for control and uses a second connection on port 20 to download and upload files.

Which statement is true about the operations of the IPv4 protocol? IPv4 includes additional fields in the IP header, which are required for reliable delivery of the packet. IPv4 operates independently of the media that carry the data at lower layers of the protocol stack. IPv4 provides error control and tracking for the data delivery, and retransmits the packet if it is corrupted. IPv4 is a connection-oriented protocol that requires some control data to be exchanged to establish the connection before data transmission.
