Microsoft PRO:MS SQL Serv 08,Design,Optimize, and Maintain DB Admin Solu Sample Questions:

1. You administer four SQL Server 2008 instances. Each instance hosts a single database application.
You plan to migrate all four instances to a new SQL Server failover cluster. The four instances are configured as shown in the following table.
Instance Name Configuration:
Instance 1 8 processors that have 16-GB RAM Instance 2 4 processors that have 8-GB RAM Instance 3 2 processors that have 16-GB RAM Instance 4 4 Processors that have 8-GB RAM
The four instances are fully optimized and have no spare CPU cycles or extra memory. The new cluster will host all four databases on a single virtual cluster IP address. You need to ensure that the new cluster is configured to handle the workload of all the database applications by using the minimum amount of hardware resources.
Which cluster configuration should you use?

A) Two-node active/passive cluster that has each node containing a minimum of 18 processors and a 50GB memory
B) Four-node active/active/active/active cluster that has each node containing a minimum of 9 processors and a 25-GB memory
C) Four-node active/active/active/passive cluster that has each node containing a minimum of 18 processors and a 50-GB memory
D) Two-node active/active cluster that has each node containing a minimum of 9 processors and a 25-GB memory

2. You administer a SQL Server 2008 infrastructure. You plan to design an infrastructure for a new application.
The application has the following requirements:
Users can connect to an instance named SQLSERVER1.
SQLSERVER1 is linked to a server named SQLSERVER2.
SQLSERVER1 and SQLSERVER2 run on different computers.
The SQL Server instances use only Windows authentication.
You need to configure the infrastructure to ensure that the distributed queries are executed in the Windows security context of the login.
Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)

A) Configure all servers to use the Shared Memory network protocol.
B) Ensure that the two instances use the same Windows account for the Microsoft SQL Service. Create the link so that each account uses the current security context.
C) Register a server principal name (SPN) for SQLSERVER1 and SQLSERVER2.
D) Create a map for each SQL login from SQLSERVER1 to SQLSERVER2 and use the impersonate option.
E) Use the local computer account as a service account for SQLSERVER1 and SQLSERVER2.

3. You are configuring a new SQL Server installation.
The SQL Server instance will be used for both online analytical processing (OLAP) and relational data. The data in the server is accessed frequently. You can configure the services, startup type, and accounts used by the services that run on the server according to the following table:

You want to raise the level of security on the server. You need to minimize the surface area for potential attacks on the server.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A) Change the Startup type property for all the services to Disabled.
B) Create a single non-administrative local user account and assign it to each of the services.
