    What is a Benefit of using a Proxy Server?

    A) It increases the requirements for bandwidth on the Internet connection

    B) Automated access to the Internet for workstations

    C) Prevents the workstations IP address from being seen externally

    D) It automatically assigns IP addresses to users

    :blink



    Good Luck, and once again please use the Hide tags to prevent influencing others in their decisions.

    A) It increases the requirements for bandwidth on the Internet connection

    Wrong - it decreases the use of bandwidth.

    B) Automated access to the Internet for workstations

    Yes, true if the workstations are set to auto-discover a proxy server and the proper WPAD entries are configured in DHCP/DNS

    C) Prevents the workstations IP address from being seen externally

    This is more a function of PAT/NAT but if the Proxy server had a public IP on it's external NIC this would be a true statement.

    D) It automatically assigns IP addresses to users

    That is what DHCP and APIPA do lol.

    Well done to everyone who said C.

    A proxy prevents local IP addresses from being seen externally, although as Bluerinse rightly points out this is a form of NAT / PAT.

    It is worth mentioning, although not mentioned by the question, that Proxy servers are also regullarly used for the Caching of frequently visited web pages.

    WPAD = "Windows proxy automatic discovery"

    So what did you think of my answer to B? :twisted:

    Assigning IP addresses or to use the correct term Leasing IP address, is handled by a DHCP (Dynamic Host Configuration Protocol) server. It is possible to have the DHCP server running on the same box as a Proxy server but they are in effect two separate functions.

    I actualy thought that could have been the correct answer when I first read the question, however, as you say, the PC's need to be manually configured to automatically detect a Proxy. :blink

    No Simon, I am saying it can be done automatically using a WPAD entry in DNS or it can even be done using DHCP. It is a scope option. There is no configuration necessary on the client. I think the auto discovery option is ticked by default.
