QUESTION 1

You administer a SQL Server 2014 instance. 

The server is capable of 10000 IO/second (IOPS). During the time period when the second process executes, the disk

IO can reach 7000 IOPS, and CPU use can average 30% over the eight processors. 

The first process summarizes the day\\’s activity executed by a login of [SummaryReportLogin]. The second process

submits transactions executed by a login of [ETLLogin]. 

A Resource Governor classifier function has been created to return WG_Low for connections from the [ETLLogin] and

[SummaryReportLogin]. 

You need to set up the Resource Group and Workgroup Pools on the instance. 

You have the following requirements: 

1. 

Both processes must never use more than 50 percent of the CPU at any one time. 

2. 

The number of active queries that these processes can execute simultaneously should be limited to a maximum of 10. 

3. 

The SummaryReportLogin process must always achieve the minimum IOPS required to be minimally affected during

executing the ETLLogin processes. 

Develop the solution by selecting and arranging the required code blocks in the correct order. 

You may not need all of the code blocks.

Note:
CREATE WORKLOAD RESOURCE POOL
*
Resource pools. A resource pool, represents the physical resources of the server. You can think of a pool as a virtual
SQL Server instance inside of a SQL Server instance.
*
Workload groups. A workload group serves as a container for session requests that have similar classification criteria.
A workload allows for aggregate monitoring of the sessions, and defines policies for the sessions. Each workload group
is
in a resource pool.
*
CAP_CPU_PERCENT =value
Specifies a hard cap on the CPU bandwidth that all requests in the resource pool will receive. Limits the maximum CPU
bandwidth level to be the same as the specified value. value is an integer with a default setting of 100. The allowed
range
for value is from 1 through 100.
*
MIN_IOPS_PER_VOLUME =value
Specifies the minimum I/O operations per second (IOPS) per disk volume to reserve for the resource pool.
*
GROUP_MAX_REQUESTS =value
Specifies the maximum number of simultaneous requests that are allowed to execute in the workload group. value must
be a 0 or a positive integer.

QUESTION 2
You have a database named database1. Each table in database1 has one index per column.
Users often report that creating items takes a long time.
You need to perform the following maintenance tasks:
Identify unused indexes.
Identify indexes that need to be defragmented.
What should you use?
To answer, drag the appropriate function to the correct management task in the answer area. (Answer choices may be
