If your server needs complete fault tolerance for authentication on the network, which of the following would you consider?
Correct Answer
C. Server mirroring
Explanation
Disk mirroring and disk duplexing will help retain the data of the last transaction when the server crashes, but cannot help with maintaining total network availability. It will require some downtime for the server to be brought up again. Server mirroring will help by keeping the users transparent to server crash by taking over the authentication process automatically.

Which of the following would you require to install NAFT on a Windows NT Server? Choose two.
Correct Answer(s)
A. NIC driver
C. AltVLAN protocol
Explanation
When installing NAFT for a Windows NT Server, you would require the Gigabit Ethernet driver, which not only contains the NIC driver but also the AltVLAN protocol that is required to accomplish the said configuration.
VPN Service and Service pack is not required for the said configuration.
4.
Which of the following are the responsibilities of the AltVLAN protocol when used for NAFT? Choose two.
Correct Answer(s)
A. Teaming
B. Load Balancing
Explanation
As evident AltVLAN is used for NAFT (Network Adapter Fault Tolerance). When using redundancy for fault tolerance it is very critical to ensure that there is a good co-ordination between the live interface and the backup to ensure automatic take over of the back up during failures. Along with this redundancy also helps in situation when the live interface is active but is handling more load of network traffic than it can handle. This is done through load balancing. The AltVLAN protocol helps in this team up and load balancing.

6.
When should you use DNS instead of WINS to resolve a computer name into an IP address?
Correct Answer
C. When the name being requested has a period (.) in it
Explanation
An LMHOSTS file is used when a name server is not available to resolve NetBIOS names. A HOSTS file is used when a name server is not available to resolve fully-qualified domain names (FQDNs). DNS names use periods to separate domain and sub-domain names. NetBIOS names include backslashes, and are serviced by WINS, not DNS.

10.
When using Server mirroring on the network, if one of the hard disks of the Primary Server crashes, which of the following would occur?
Correct Answer
B. Only the disk I/O operations will be performed on the Secondary server instead of the Primary Server
Explanation
Unless the disk housing the OS on the Primary Server fails the Secondary server will not take over. The two servers� internal bus is connected, hence, if the disk drive fails only the I/O operations, only that task will be transferred to the Secondary server.
11.
Which of the following statements are true? Choose all that apply.
Correct Answer(s)
A. Disk mirroring and disk duplexing are the same level of RAID
B. Disk duplexing needs and extra controller for mirroring
Explanation
Disk mirroring and duplexing are the same level of RAID. The only difference is in the hardware configuration. IF an extra controller exists in the server, when the mirroring option is chosen, the OS assumes you are configuring duplexing and will go ahead with that configuration.
12.
What happens when a system partition is mirrored? Choose all that apply
Correct Answer(s)
