Question
1 . How does an NLB cluster provide fault tolerance?
A) Based on an internal algorithm, the servers decide which server should respond to each incoming client request.
B) A failed server can be removed from the cluster and another server can take its place.
C) DNS records are changed to point clients to a different server if one fails.
D) RAID and multiple NICs are used.
2.
Which of the following describes high availability? (Choose all that apply.)
A) Applications that are available even in the event of a system failure
B) A server that requires no more than one restart per week
C) Fast response time from a service or application when two or more servers spread the workload
D) An OS that detects when a memory error has occurred
3.
You have a Web site serving mostly static content, and the current server is unable to handle the traffic load. You think you need three servers to handle the traffic load adequately, but you want to be able to prioritize how much traffic each server handles. Which high-availability solution makes the most sense?
A) Create a round-robin load balancing configuration by using DNS.
B) Use the failover cluster feature in Windows Server 2012
C) Use the distributed Web server feature in Windows Server 2012.
D) Use the network load balancing feature in Windows Server 2012.

Which of the following is not a step in creating and configuring an NLB cluster?
A) Configuring the host priority
B) Setting the cluster IP address
C) Configuring port rules
D) Configuring a preferred owner
5.
Which of the following is a valid NLB cluster operation mode?
A) Single host
B) Network
C) Multicast
D) Suspended
6.
Which filtering mode should you use when you want to provide scalability for several servers in an NLB cluster?
A) Multiple host
B) Failback immediate
C) IGMP multicast
D) Node majority
7.
Under which circumstances should you use the None option when setting the client affinity value?
A) When you want multiple requests from the same client to be directed to the same cluster host
B) When clients access the cluster from behind multiple proxy servers
C) When the content being served is fairly static and stateless
D) When you want the cluster to discard packets matching the specified protocol and ports
8.
Which of the following serves as an NLB cluster server identifier and determines which server will handle traffic not covered by a port rule?
A) Dedicated IP address
B) Port range
C) Priority
D) Affinity value
9.
You manage an NLB cluster composed of three servers: Server1, Server2, and Server3. Your maintenance schedule indicates that Server1 is due for cleaning maintenance, which involves vacuuming dust and reseating all components. The NLB cluster is in constant use, so you don’t want to interrupt any clients currently being served by Server1. Which option should you use to take Server1 temporarily offline yet allow it to complete active client requests?
A) Stop
B) Suspend
C) Resume
D) Drainstop
10.
Which of the following is a failover cluster server that doesn’t respond to client requests but is available to do so if the active server fails?
A) Passive node
B) Quorum node
C) Active node
D) Suspended node
11.
Which of the following describes a cluster that has been divided into two or more subclusters because of lack of communication?
A) Quorum
B) Partitioned
C) No majority
D) Sanctioned
12.
You’re configuring a failover cluster and want a quorum configuration that can endure the failure of all but one server and remain operational. Which quorum configuration should you choose?
A) Node Majority
B) No Majority: Disk Only
C) Node and File Share Majority
D) Node and Disk Majority
13.
Which of the following is a valid quorum model? (Choose all that apply.)
A) Node Majority
B) No Majority: Disk Only
C) Node and Disk Majority
D) File Share and Disk Majority
14.
Which of the following is a requirement for creating a failover cluster? (Choose all that apply.)
A) Two or more stand-alone servers
B) Two or more quad-core CPUs

15.
What’s created in Active Directory during the failover cluster creation process?
A) A computer object with the name of the cluster
B) A SAN object with the name of the witness disk
C) An A record with the name and IP address of the cluster
D) A cluster object containing the names of all the cluster servers
16.
Which of the following is true about the network configuration of failover clusters?
A) The shared storage should be on the same subnet as cluster clients.
B) Cluster servers require a minimum of three NICs.
C) The iSCSI storage server should be on a separate subnet from cluster clients.
D) All NICs on each server must be configured on the same subnet.
17.

B) CAU
C) CSV
D) SAS
