  1. 11. Which of the following describes high availability? (Choose all that apply.)
    1. AApplications that are available even in the event of a system failure
    2. BA server that requires no more than one restart per week
    3. CFast response time from a service or application when two or more servers spread the workload
    4. DAn OS that detects when a memory error has occurred
  2. 2How does an NLB cluster provide fault tolerance?
    1. ABased on an internal algorithm, the servers decide which server should respond to each incoming client request.
    2. BA failed server can be removed from the cluster and another server can take its place.
    3. CDNS records are changed to point clients to a different server if one fails.
    4. DRAID and multiple NICs are used.
  3. 3You 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?
    1. ACreate a round-robin load balancing configuration by using DNS.
    2. BUse the failover cluster feature in Windows Server 2012.
    3. CUse the distributed Web server feature in Windows Server 2012.
    4. DUse the network load balancing feature in Windows Server 2012.
  4. 4Which of the following is not a step in creating and configuring an NLB cluster?
    1. AConfiguring the host priority
    2. BSetting the cluster IP address
    3. CConfiguring port rules
    4. DConfiguring a preferred owner
  5. 5Which of the following is a valid NLB cluster operation mode?
    1. ASingle host
    2. BNetwork
    3. CMulticast
    4. DSuspended
  6. 6Which filtering mode should you use when you want to provide scalability for several servers in an NLB cluster?
    1. AMultiple host
    2. BFailback immediate
    3. CIGMP multicast
    4. DNode majority
  7. 7Under which circumstances should you use the None option when setting the client affinity value?
    1. AWhen you want multiple requests from the same client to be directed to the same cluster host
    2. BWhen clients access the cluster from behind multiple proxy servers
    3. CWhen the content being served is fairly static and stateless
    4. DWhen you want the cluster to discard packets matching the specified protocol and ports
  8. 8Which of the following serves as an NLB cluster server identifier and determines which server will handle traffic not covered by a port rule?
    1. ADedicated IP address
    2. BPort Range
    3. CPriority
    4. DAffinity value
  9. 9You 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?
    1. AStop
    2. BSuspend
    3. CResume
    4. DDrainstop
  10. 10Which 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?
    1. APassive Mode
    2. BQuorum node
    3. CActive node
    4. DSuspended node
