It is designed to prevent administrators from having to load backup media to restore individual files for users

The application high availability mechanism that uses redundant servers, with all running simultaneously, is called ______.

Network Load Balancing.

The Windows Server 2008 feature that enables end users to store copies of server-based documents on a local drive is called ______.

What mechanism automatically retains copies of files on a server volume in multiple versions from specific points in time?

Shadow Copies.

Windows Server 2008 servers can maintain multiple versions of a volume's files using a feature called _____.

TS Session Broker.

What is the main disadvantage of DNS Round Robin?

The DNS server has no connection with the servers in the cluster.

What two parts constitute the process of deploying Terminal Services with network load balancing?

The two parts include creating a terminal server farm and creating a network load balancing cluster.

How do you access shadow copies once they have been created?

To access the shadow copies stored on a server, a computer must be running the Previous Versions Client.

True.

What is convergence, and what triggers it?

When a server fails to generate five consecutive heartbeats, the cluster initiates a process called convergence, which stops it from sending clients to the missing server.

To use DNS Round Robin, you must first create a cluster resource record specifying the cluster name. d. When the Windows Server 2008 DNS server receives a name resolution request for a cluster, it replies with all of the resource records for that cluster name.

a. DNS Round Robin requires you to create multiple resource records containing the same host name.

9. Which of the following statements best defines the function of the port rules in an NLB cluster? a.
