70-765 Exam - Question 18


HOTSPOT -

Background -

You are the database administrator for Contoso, Ltd. The company has 200 offices around the world. The company has corporate executives that are located in offices in London, New York, Toronto, Sydney, and Tokyo.

Contoso, Ltd. has a Microsoft Azure SQL Database environment. You plan to deploy a new Azure SQL Database to support a variety of mobile applications and public websites.

The company is deploying a multi-tenant environment. The environment will host Azure SQL Database instances. The company plans to make the instances available to internal departments and partner companies. Contoso is in the final stages of setting up networking and communications for the environment.

Existing Contoso and Customer instances need to be migrated to Azure virtual machines (VM) according to the following requirements:

✑ Contoso instances should use the method requiring the least administrative effort to migrate instances to Azure Vms.

✑ Customer instances should use a method that allows customers to bring their own licenses to Azure VMs. Customers have approved down time for the migration.

The company plans to deploy a new order entry application and a new business intelligence and analysis application. Each application will be supported by a new database. Contoso creates a new Azure SQL database named Reporting. The database will be used to support the company's financial reporting requirements.

You associate the database with the Contoso Azure Active Directory domain.

Each location database for the data entry application may have an unpredictable amount of activity. Data must be replicated to secondary databases in Azure datacenters in different regions.

To support the application, you need to create a database named contosodb1 in the existing environment.

Objects -

Database -

The contosodb1 database must support the following requirements:

✑ a size of at least 200 gigabytes (GB)

✑ 1,000 concurrent sessions

✑ point-in-time restore to any point in the two weeks prior to a failure

✑ minimize costs

Application -

For the business intelligence application, corporate executives must be able to view all data in near real-time with low network latency.

Contoso has the following security, networking, and communications requirements:

✑ Multi-Location Load Balancing to ensure customers have access to their tenants at multiple Azure locations across the world.

✑ Secure Message/Data Flow to securely support communication between Azure and on-premises applications and services.

✑ Accounts should support accessing external domain resources and be configured in the most secure and lowest-maintenance way possible, including meeting the company policy of regular service account password changes.

You need to configure the data entry and business intelligence databases.

In the table below, identify the option that you must use for each database.

NOTE: Make only one selection in each column.

Correct Answer:

Data Entry: Geo-replicated database only

From Contoso scenario: Each location database for the data entry application may have an unpredictable amount of activity. Data must be replicated to secondary databases in Azure datacenters in different regions.

Business intelligence: Elastic database pools only

From Contoso scenario: For the business intelligence application, corporate executives must be able to view all data in near real-time with low network latency.

SQL DB elastic pools provide a simple cost effective solution to manage the performance goals for multiple databases that have widely varying and unpredictable usage patterns.

I think this answer is wrong. The elastic pools + geo replication seems to be the right answer for the data entry database, because it is unpredictable but needs lower cost. The BI database seems to need geo replication for load balancing across locations. But I'm not sure it needs the elastic function.

You are correct. For BI, it says view all data in near real time and with low letency which is only possible if you access that from nearest location. for Data: Unpredictable usage and replicaiton, it shoudl be both, Geo replication and elastic pool

Data Entry: Geo- Replicated Only This is because each location database for the data entry may have an unpredicted amount of activity thus data must be replicated to secondary databases in Azure datacentres in different regions. Business Intelligence: Elastic database pools only. This is because corporate executives must be able to view all data in near real-time with low network latency and the pools are used for multiple databases that have widely varying and unpredictable usage patterns.

Data entry : Geo replicated data base only Business intelligence : Elastic database pools only From contoso scenario : Each location database for the data entry application may have an unpredictable amount of activity. Data must be replicated to secondary databases in Azure datacenters in different regions. From Contoso scenario: For the business intelligence application, corporate executives must be able to view all data in near real-time with low network latency.
