• Question 221:

  What popular application is used to access a Windows server remotely?

  A. remote assistance

  B. remote desktop

  C. TELNET

  D. SSH

  Correct Answer: B

  With early networks, users utilized dumb terminals (systems consisting of a monitor and keyboard without a processor) to connect to a mainframe. Later, computers could use TELNET to connect to a server and execute commands at a command prompt. Remote Desktop Services, formerly known as Terminal Services, is one component of Microsoft Windows that allows users to access applications and data on remote computers over a network.

• Question 222:

  Which form of authentication sends username and password in clear text?

  A. PAP

  B. CHAP

  C. MS-CHAP

  D. EAP

  Correct Answer: A

  Password Authentication Protocol (PAP) uses plain text (unencrypted passwords). PAP is the least secure authentication and is not recommended.

• Question 223:

  What does L2TP use to encrypt data?

  A. IPSec

  B. PPTP

  C. MPPE

  D. SSTP

  Correct Answer: C

• Question 224:

  What technology is used to link two computers or sites over the Internet while providing a secure connection?

  A. FTP

  B. SMTP

  C. VPN

  D. telnet

  Correct Answer: C

  Virtual private networks (VPNs) link two computers through a wide-area network such as the Internet. To keep the connection secure, the data sent between the two computers is encapsulated and encrypted.

• Question 225:

  What protocol is used to transfer files to or from a server?

  A. FTP

  B. SNMP

  C. VPN

  D. SMTP

  Correct Answer: A

  File Transfer Protocol (FTP) is used to transfer files to or from a server. Most FTP sites are used primarily to download files. In most of these situations, FTP uses anonymous authentication, in which username and password are not required.

• Question 226:

  What is used to store and distribute a public key?

  A. digital certificate

  B. digital signature

  C. digital lock

  D. digital envelope

  Correct Answer: A

  When you use SSL to encrypt web traffic, you are using asymmetric encryption, which involves a private key and a public key. The public key is provided to anyone who wants to access the web server, and the private key is kept secret, usually by the web server that you are trying to protect. A common method to distribute a public key is to use a digital certificate.

• Question 227:

  Which type of IIS authentication sends the username and password in clear text?

  A. anonymous

  B. ASP.NET Impersonation

  C. Basic Authentication

  D. Windows Authentication

  Correct Answer: C

  Basic Authentication requires that users provide a valid username and password to gain access to content. Because basic authentication transmits passwords across the network in clear text, you should use it with a digital certificate to encrypt usernames and passwords being sent over the network.

• Question 228:

  Which type of IIS authentication does not provide a username and password?

  A. anonymous

  B. ASP.NET Impersonation

  C. Basic Authentication

  D. Windows Authentication

  Correct Answer: A

  Authentication is used to confirm the identity of clients who request access to your sites and applications. Anonymous authentication allows access without providing a username and password.

• Question 229:

  When IIS is running multiple websites, what do you use to isolate one site from another website?

  A. applications

  B. application pools

  C. sites

  D. virtual directories

  Correct Answer: B

  An application pool is a set of resources (a worker process or a set of worker processes) used by a website or application that defines the memory boundaries for the site. Forcing each application to have its own application pool ensures that

  one site does not interfere with another site on the same server, which ensures application performance and improved application availability.

  Therefore, if one application has a memory leak or crashes, it will not affect the other sites.

• Question 230:

  By default, what port does SMTP use?

  A. 80

  B. 23

  C. 25

  D. 21

  Correct Answer: C

  SMTP uses TCP port 25.
