• Question 223:

  Background

  Corporate Information

  Fabrikam, Inc. is a retailer that sells electronics products on the Internet. The company has a headquarters site and one satellite sales office. You have been hired as the database administrator, and the company wants you to change the

  architecture of the Fabrikam ecommerce site to optimize performance and reduce downtime while keeping capital expenditures to a minimum. To help with the solution, Fabrikam has decided to use cloud resources as well as on-premise

  servers.

  Physical Locations

  All of the corporate executives, product managers, and support staff are stationed at the headquarters office. Half of the sales force works at this location. There is also a satellite sales office. The other half of the sales force works at the

  satellite office in order to have sales people closer to clients in that area. Only sales people work at the satellite location.

  Problem Statement

  To be successful, Fabrikam needs a website that is fast and has a high degree of system uptime. The current system operates on a single server and the company is not happy with the single point of failure this presents. The current nightly

  backups have been failing due to insufficient space on the available drives and manual drive cleanup often needing to happen to get past the errors. Additional space will not be made available for backups on the HQ or satellite servers.

  During your investigation, you discover that the sales force reports are causing significant contention.

  Configuration

  Windows Logins

  The network administrators have set up Windows groups to make it easier to manage security. Users may belong to more than one group depending on their role. The groups have been set up as shown in the following table:

  

  Server Configuration The IT department has configured two physical servers with Microsoft Windows Server 2012 R2 and SQL Server 2014 Enterprise Edition and one Windows Azure Server. There are two tiers of storage available for use by database files only a fast tier and a slower tier. Currently the data and log files are stored on the fast tier of storage only. If a possible use case exists, management would like to utilize the slower tier storage for data files. The servers are configured as shown in the following table:

  

  Database

  Currently all information is stored in a single database called ProdDB, created with the following script:

  

  The Product table is in the Production schema owned by the ProductionStaff Windows group. It is the main table in the system so access to information in the Product table should be as fast as possible. The columns in the Product table are defined as shown in the following table:

  

  The SalesOrderDetail table holds the details about each sale. It is in the Sales schema owned by the SalesStaff Windows group. This table is constantly being updated, inserted into, and read. The columns in the SalesOrderDetail table are defined as shown in the following table:

  

  Database Issues

  The current database does not perform well. Additionally, a recent disk problem caused the system to go down, resulting in lost sales revenue. In reviewing the current system, you found that there are no automated maintenance procedures.

  The database is severely fragmented, and everyone has read and write access.

  Requirements

  Database

  The database should be configured to maximize uptime and to ensure that very little data is lost in the event of a server failure. To help with performance, the database needs to be modified so that it can support in-memory data, specifically

  for the Product table, which the CIO has indicated should be a memoryoptimized table. The auto-update statistics option is set off on this database. Only product managers are allowed to add products or to make changes to the name,

  description, price, cost, and supplier. The changes are made in an internal database and pushed to the Product table in ProdDB during system maintenance time. Product managers and others working at the headquarters location also should

  be able to generate reports that include supplier and cost information.

  Customer data access

  Customers access the company's website to order products, so they must be able to read product information such asname, description, and price from the Product table. When customers place orders, stored procedures calledby the website

  update product quantityon-hand values. This means the product table is constantly updated at randomtimes.

  Customer support data access

  Customer support representatives need to be able to view and not update or change product information. Management does not want the customer support representatives to be able to see the product cost or any supplier information.

  Sales force data access

  Sales people at both the headquarters office and the satellite office must generate reports that read from the Product and SalesOrderDetail tables. No updates or inserts are ever made by sales people. These reports are run at random times

  and there can be no reporting downtime to refresh the data set except during the monthly maintenance window. The reports that run from the satellite office are process intensive queries with large data sets. Regardless of which office runs a

  sales force report, the SalesOrderDetail table should only return valid, committed order data; any orders not yet committed should be ignored.

  Historical Data

  The system should keep historical information about customers who access the site so that sales people can see how frequently customers log in and how long they stay on the site.

  The information should be stored in a table called Customer Access. Supporting this requirement should have minimal impact on production website performance.

  Backups

  The recovery strategy for Fabrikam needs to include the ability to do point in time restores and minimize the risk of data loss by performing transaction log backups every 15 minutes.

  Database Maintenance

  The company has defined a maintenance window every month when the server can be unavailable. Any maintenance functions that require exclusive access should be accomplished during that window.

  Project milestones completed

  Revoked all existing read and write access to the database, leaving the schema ownership in place.

  Configured an Azure storage container secured with the storage account name MyStorageAccount with the primary access key StorageAccountKey on the cloud file server.

  SQL Server 2014 has been configured on the satellite server and is ready for use.

  On each database server, the fast storage has been assigned to drive letter F:, and the slow storage has been assigned to drive letter D:.

  You are designing your maintenance plan.

  Which command should you use only during the monthly maintenance window?

  A. DBCC INDEXDEFRAG (ProdDB, SalesOrderDetail, SODIndex)
  B. ALTER INDEX SODIndex ON SalesOrderDetail REORGANIZE
  C. ALTER INDEX SODIndex ON SalesOrderDetail REBUILD
  D. ALTER INDEX SODIndex ON SalesOrderDetail REBUILD WITH (ONLINE * ON)
  D. ALTER INDEX SODIndex ON SalesOrderDetail REBUILD WITH (ONLINE * ON)

• Question 224:

• Question 228:

  HOTSPOT

  A company has the following Microsoft SQL Server instances Instance1 and Instance2.

  You plan to enable Always Encrypted for both instances.

  You need to configure the instances to meet the following requirements:

  Instance1 must use an initialization vector that is different each time the instance is initiated.

  Instance2 must use an initialization vector that is derived from an algorithm.

  In the table below, identify the encryption type that must be used for each instance.

  NOTE: Make only one selection in each column. Each correct selection is worth one point.

  Hot Area:

  

  

• Question 229:

  HOTSPOT

  You have a Microsoft SQL Server instance that hosts a database named DB1 that contains 800 gigabyte (GB) of data. The database is used 24 hours each day. You implement indexes and set the value of the Auto Update Statistics option set to True.

  Users report that queries take a long time to complete.

  You need to identify statistics that have not been updated for a week for tables where more than 1,000 rows changed.

  How should you complete the Transact-SQL statement? To answer, configure the appropriate Transact-SQL segments in the answer area.

  Hot Area:

  

  

  ---

  Box 1: stats_date

  See example below.

  Box 2: rowmodctr

  See examplebelow.

  Box 3: stats_date

  You need to identify statistics that have not been updated for a week.

  Box 4: rowmodctr

  You need to identify that more than 1,000 rows changed.

  Rowmodctr counts the total number of inserted, deleted, or updated rows since the last time statistics were updated for the table.

  Example: We will query every statistics object which was not updated in the last day and has rows modified since the last update. We will use the rowmodctr field of sys.sysindexes because it shows how many rows were inserted, updated or

  deleted since the last update occurred. Please note that it is not always 100% accurate in SQL Server 2005 and later, but it can be used to check if any rows were modified.

  --Get the list of outdated statistics

  SELECTOBJECT_NAME(id),name,STATS_DATE(id, indid),rowmodctr FROM sys.sysindexes

  WHERE STATS_DATE (id, indid)<=DATEADD(DAY,-1,GETDATE())

  AND rowmodctr>0

  AND id IN (SELECT object_id FROM sys.tables)

  GO

  After collecting this information, we can decide which statistics require an update.
