You are experiencing issues when trying to transfer filesbetween two computers using FTP. What could be the potentialcause(s) of the issue? Select all that apply.

	Server is not able to resolve the client IP address
	Inbound port UDP 21 is blocked in the server
	The remote host does not allow connections on high ports 49152 -65535
	Inbound port TCP 21 is blocked in the server
	Client is not able to resolve the remote IP address

Which of the following best describes the function of theTTL/hop limit for IP packages?

	Prevents a computer from keeping the same IP forever, whichcould potentially cause IP address conflicts in the network(perhaps due to incorrect DHCP configuration)
	Tells the client for how long it should cache the localephemeral port used in a TCP connection to allow fastreconnections
	Indicates to the server for how long it should keep a TCPconnection with a specific client to mitigate denial-of-service(DoS) attack
	Prevents IP packets from getting stuck in infinite routing loops(perhaps due to incorrect routing tables)
