Proseware has two offices located in Seattle and Montreal. The Seattle office contains all of the hardware required to host its customers- websites, web apps, and databases. The Seattle off

ice contains the IT team for the hosting environment.

The Montreal office contains all of the hardware required to host the company-s internal applications, databases, and websites.

Each office connects directly to the Internet. Testing reveals that the

Existing Environment

Internal Microsoft SQL Server Environment

Proseware uses a custom customer relationship management (CRM) application.

The internal Microsoft SQL Server environment contai

ns two physical servers named CRM-A and CRM-B. Both servers run SQL Server 2012 Standard and host databases for the CRM application.

CRM-A hosts the principal instance and CRM-B hosts the mirrored instance of the CRM database.

С

RM-A also hosts databases

for several other applications that are used by the company-s internal applications.

CRM-A has a quad core processor and 12 GB of RAM. CRM-

Ð’

has a dual core processor and 8 GB of RAM.

Custom Web Applications Environment

Some Proseware customers request c

ustom web-based applications that require more than just databases, such as SQL Server Integration Services (SSIS) and CLR stored procedures.

Proseware uses a Hyper-V server named Host1. Host1 has four instances of SQL Server 2014 Enterprise in the host o

perating system. The instances are mirrored on a server named Host2.

Host1 also hosts four virtual machines named VM1, VM2, VM3, and VM4. VM1 has SQL Server 2005 Standard installed. VM2 has SQL Server 2005 Enterprise Edition installed. VM3 has SQL Server

2008 Standard Edition installed. VM4 has SQL Server 2008 R2 Standard Edition installed.

Host1 uses a SAN to store all of the data and log files for the four SQL Server instances and the four virtual machines.

Websites and Basic Web Apps Environment

Prose

ware has two physical servers named WebServer1 and WebData1. WebServer1 hosts basic web apps and websites for its customers. WebData1 has a database for each website and each basic web app that Proseware hosts. WebData1 has four cores and 8 GB of RAM.

Eac

h website database contains customer information for billing purposes. Proseware generates a consolidated report that contains data from all of these databases.

The relevant databases on WebData1 are:

CWDB: Currently 60 GB and is not expected to exceed 10

0 GB. CWDB contains a table named PersonalInfo.

MovieReviewDB: Currently 5 GB and is not expected to exceed 10 GB.

Marketing Department

Proseware has a web app for the marketing department. The web app uses an Azure SQL database. Managers in the marketing

department occasionally bulk load data by using a custom application. The database is updated daily.

Problem Statements

Proseware identifies the following issues:

Lack of planning and knowledge has complicated the database environment.

Customers who have

web apps hosted on WebServer1 report frequent outages caused by failures on WebData1. The current uptime is less than 90 percent.

Internally, users complain of slow performance by the CRM application when the databases fail over to CRM-B.

WebData1 has no

high-availability option for the databases or the server.

An internal licensing audit of SQL Server identifies that Proseware is non-compliant. Host1, CRM-A, and CRM-Ð’ are licensed properly. VM1, VM2, VM3, VM4, and WebData1 are unlicensed.

Business Requir

ements

Proseware identifies the following business requirements:

Upgrade the infrastructure to address the issues reported by the internal users and customers.

Minimize upgrade costs associated with purchasing hardware and software.

Ensure that all softwar

e is licensed properly.

Minimize the complexity of the database environment.

Consolidate the instances of SQL Server that support the custom web app environment.

Implement a service level agreement (SLA) of 99.95 percent uptime for the website and basic we

b app environment.

Implement a disaster recovery environment in Azure for the CRM application.

Ensure that any changes to the SQL Server environments either maintain or increase overall performance.

Migrate all web front ends to Azure.

Reuse licenses, when

ever possible.

Minimize the administrative effort required to generate the internal reports from the website databases.

Security Requirements

Proseware hosts a database for a company named Contoso, Ltd. Currently, all of the employees at Contoso can acces

s all of the data in the database.

Contoso plans to limit user access to the CWDU database so that customer service representatives can see only the data from the PersonalInfo table that relates to their own customers.

You need to recommend a disaster r

ecovery solution for the CRM application that meets the business requirements.

What should you recommend?

A. backup and restore by using Windows Azure Storage

B. log shipping

C. AlwaysOn Availability Groups

D. database mirroring
