Which statement is true concerning DHCP?

A.     DHCP is used to automate IP address assignment.

B.     DHCP is used to resolve host names to IP addresses.

C.     DHCP is used to resolve NetBIOS names to IP addresses.

D.     DHCP is used to verify the IP address on a Windows-based computer.

Answer:

A. DHCP is used to automate IP address assignment.

Tutorial:

Dynamic Host Configuration Protocol (DHCP) is a standards-based networking protocol used to automate the assignment of IP addresses to DHCP client devices. DHCP is a client/server protocol that uses two components: one on the server and one on the client. The server-side component stores a pool of available IP addresses. The client-side component requests a TCP/IP configuration from an available DHCP server.

Several server operating systems support the DHCP server service, including Windows NT Server, Windows 2000 Server, Windows Server 2003, Novell NetWare 6 and Red Hat Linux 9. Most desktop operating systems support the DHCP client service.

Domain Name System (DNS) is a network service that is used to resolve host names to IP addresses. DNS is used extensively on the Internet; for example, DNS can be used to resolve the host name www.verigon.com to that Web server's corresponding IP address.

Windows Internet Naming Service (WINS) is a network service that can be used to resolve NetBIOS names to IP addresses. NetBIOS names are also known as Windows computer names.

The Ipconfig command can be used to verify the IP address of a Windows-based computer.

What should you do if you discover inappropriate material on a company-owned computer and a company computer-use policy exists that addresses this specific situation?

A.     Inform your supervisor of the inappropriate material.

B.     Inform the user's supervisor of the inappropriate material.

C.     Ask the user to remove the inappropriate material.

D.     Follow the procedures for dealing with this violation.

Answer:

D. Follow the procedures for dealing with this violation.

Tutorial:

If you discover inappropriate material on a company-owned computer and a computer-use policy exists, you should follow the procedures for dealing with this violation. The policies in place contain the guidelines for reporting any violations of the Acceptable Usage Agreement. If a user signs the Acceptable Usage Agreement, he or she is bound by that agreement and its terms.

The Acceptable Usage Agreement should include details on what is considered unacceptable behavior on computer usage. It should also give possible repercussions.

While the other options may be included as part of the policies for dealing with violations, you should always consult the procedures documentation and follow them exactly.
