FTP transfers files from one platform to another, often for larger files. HTTP is a building block of TCP/IP. HTTP performs a check to ensure files arrived as sent.
The correct answer is A.
B is incorrect because FTP is not faster than HTTP, nor is it used for almost all Web file transfers. C is incorrect because FTP is not a firewall protocol. D is incorrect because HTTP is not a building block of TCP/IP, nor does it perform a check to ensure files arrive as sent.
4.
Which sentence describes the correct relationship between a domain name and its IP address?
Please select the best answer.
A.
An IP address is assigned by protocol when a client visits a domain name.
B.
An IP address is assigned to a domain name and translated by DNS software.
C.
When a client visits a domain name, its IP address is recorded with cookies.
D.
An IP address indicates if the domain name ends in .com, .org, .gov, or .edu.
The correct answer is B.
Every domain name has a specific IP address. When you type in a domain name, DNS software translates it into its IP address, and your request for those documents is routed across the Internet based on that IP address. A is incorrect because when you visit a domain name site, the IP address has already been assigned. C is sometimes true, but talks about the IP address of the user, not the IP address of the domain name. D is incorrect because the extension (.gov,.com) has no bearing on the IP address.
