The answers you selected are indicated below, along with text that explains the correct answers.
 
1. Which email protocol combination below is used to specify a user account's incoming and outgoing IP address?
Please select the best answer.
  A. DNS and SNA
  B. TCP and MAILPEP
  C. POP2 and SMTP
  D. DHCP and RJ-11
  The correct answer is C.
Answer A is incorrect because DNS is used to translate domain names (Internet addresses like www.amazon.com) to IP numbers and SNA is a network protocol not discussed in this module. Answer B wrong because there is no such term as MailPep. Answer D is wrong because RJ-11 is a wire connector while DHCP is used to dynamically assign IP addresses to clients.

2. Which example of client software is required to access the Net?
Please select the best answer.
  A. Network interface card
  B. TCP/IP
  C. Ethernet
  D. Modem
  The correct answer is B. Answer B is the only client software listed among the choices. TCP/IP is the required client software required to connect your computer to the Internet. Answers A, C, and D compose hardware, not software, components and are therefore incorrect.

3. Which TCP/IP configuration setting do you not need to manually enter on the client computer?
Please select the best answer.
  A. Subnet mask
  B. IP address from DHCP server
  C. Default gateway
  D. DNS
  The correct answer is B. An IP address from a DHCP server is dynamic, meaning it is automatically assigned by the server. No human input is needed. Answers A, C, and D are all incorrect because they, to the contrary, need to be manually entered on the client computer. They do not possess a dynamic status.

4. What is a cookie?
Please select the best answer.
  A. Small piece of data stored on a client and associated with a server
  B. Small piece of data stored on a server and associated with a client
  C. Large piece of data stored on a client and associated with a server
  D. Large piece of data stored on a server and associated with a client
  The correct answer is A. A cookie is a small piece of information (about 4K) stored on a client and associated with a server. This is the sole definition of a cookie. Answers B, C, and D are therefore invalid definitions of cookies.

5. Which TCP/IP protocol suite permits multimedia content in an email?
Please select the best answer.
  A. POP3
  B. HTTP
  C. SMTP
  D. MIME
  The correct answer is D. MIME (Multipurpose Internet Mail Extensions). Answer A is wrong because POP3 is the standard protocol for downloading (or possibly uploading) email from an email server. Answer B is incorrect because HTTP is a communication protocol between a Web server and a Web browser and does not enable email activities. Answer C is incorrect because SMTP is responsible for sending email.
