16.0 Q&A with Explanations

Case Study: 1

Background

You manage the Microsoft SQL Server environment for a company that manufactures and

sells automobile parts.

The environment includes the following servers: SRV1 and SRV2. SRV1 has 16 logical cores

and hosts a SQL Server instance that supports a mission-critical application. The application

has approximately 30,000 concurrent users and relies heavily on the use of temporary tables.

The environment also includes the following databases: DB1, DB2, and Reporting. The

Reporting database is protected with Transparent Data Encryption (TDE). You plan to

migrate this database to a new server. You detach the database and copy it to the new server.

You are performing tuning on a SQL Server database instance. The application which uses

the database was written using an object relationship mapping (ORM) tool which maps tables

as objects within the application code. There are 30 stored procedures that are regularly used

by the application.

Exhibit

Question: 1

HOTSPOT

You need to optimize SRV1.

What configuration changes should you implement? To answer, select the appropriate option

from each list in the answer area.

Answer:

From the scenario: SRV1 has 16 logical cores and hosts a SQL Server instance that supports

a mission-critical application. The application hasapproximately 30,000 concurrent users and

relies heavily on the use of temporary tables.

Box 1: Change the size of the tempdb log file.

The size and physical placement of the tempdb database can affect the performance of a

system. For example, if the size that is defined for tempdb is too small, part of the system-

processing load may be taken up with autogrowing tempdb to the size required to support the

workload every time you restart the instance of SQL Server. You can avoid this overhead by

increasing the sizes of the tempdb data and log file.

Box 2: Add additional tempdb files.

Create as many files as needed to maximize disk bandwidth. Using multiple files reduces

tempdb storage contention and yields significantly better scalability. However, do not create

too many files because this can reduce performance and increase management overhead. As a

general guideline, create one data file for each CPU on the server (accounting for any affinity

mask settings) and then adjust the number of files up or down as necessary.

Question: 2

HOTSPOT

You need to resolve the identified issues.

Use the drop-down menus to select the answer choice that answers each question based on

the information presented in the graphic.

Answer:

From exhibit we see:

Cost Threshold of Parallelism: 5

Optimize for Ad Hoc Workloads: false

Max Degree of Parallelism: 0 (This is the default setting, which enables the server to

determine the maximum degree of parallelism. It is fine.)

Locks: 0

Query Wait: -1

Box 1: Optimize for Ad Hoc Workload

Change the Optimize for Ad Hoc Workload setting from false to 1/True.
