Objective 4.3
Implement a Cluster Server
17-23
B. Incorrect: An arbitrated loop is a type of Fibre Channel connection used
to cre-
ate a shared storage solution for a server cluster; it has nothing to do
with detect-
ing offline cluster servers.
C. Incorrect: Multicast is an operational mode for Network Load Balancing
clusters
and a type of Transmission Control Protocol/Internet Protocol (TCP/IP)
message
that uses a single address to represent a group of hosts. Neither of these
defini-
tions is related to the process of detecting offline cluster servers.
D. Correct: All the servers in a cluster transmit a heartbeat message once a
second
to the other cluster servers. If the heartbeats from a particular server
stop, the
other servers assume it is offline and begin the convergence process, to
compen-
sate for losing a server.
4.
Correct Answers: B and D
A. Incorrect: A Windows Server 2003 server cluster that uses a shared SCSI
storage
solution can have no more than 2 nodes.
B. Correct: A 4-node Windows Server 2003 server cluster can only use Fibre
Chan-
nel for its shared storage solution.
C. Incorrect: Although the cluster servers would benefit from the
installation of a
second network interface adapter for cluster-related traffic, it is not a
requirement.
D. Correct: A 4-node Windows Server 2003 server cluster must use a Fibre
Channel
switched fabric network as its shared storage solution, which requires the
installa-
tion of a Fibre Channel switch.
5.
Correct Answers: B, C, and E
A. Incorrect: To back up cluster disk signatures, you must use the Automated
Sys-
tem Recovery (ASR) feature in the Backup program.
B. Correct: The System State object includes the Active Directory database
as well
as boot files and other important system elements.
C. Correct: Backing up the System State element protects the cluster quorum
on any
server on which the Cluster service is running.
D. Incorrect: The System State element does not include the data stored on
cluster
disks. To back up this data, you must use a standard backup job, such as a
full
backup.
E. Correct: The System State element includes the registry, as well as boot
files and
other important system elements.
