Question 1. Under Windows NT, what command would you use if you wanted to trace a packet from its source host to a destination host?

    A. TRACERT

    B. ROUTE

    C. NBTSTAT

    D. IPCONFIG

    The TRACERT utility is Microsoft's own, used to trace a packet from its source ( your computer ) to a destination host ( a remote computer ).

    Question 2. If you wanted to display all entries in the ARP cache, which of the following utilities would you use?

    A . ARP - G

    B. ARP - E

    C. ARP - D

    D. ARP - S

    To display all entries in the ARP ( Address Resolution Protocol ) cache, you would use the ARP utility with the -G or - A switch. They are the same thing. To get the answer type "arp /?" at the command prompt.

    ARP ( Address Resolution Protocol ) is used to obtain hardware ( MAC = Media Access Control ) addresses for communications with a destination host.

    Question 3. You notice that the subnet mask is 0.0.0.0>1  

    C. route / release

    D. route / endlease

    The IPCONFIG / RELEASE command is used to send a DHCPRELEASE message from a DHCP client to a DHCP server. The DHCPRELEASE message specifies that a client wishes to give up its current lease with the DHCP server. Type, "ipconfig /?" at the command prompt to display all the switches of the utility.
 
    Question 10. You would like to see a list of NetBIOS computer names that have been resolved into IP addresses>1
