You need to provide an implementation plan to configure data retention for ResearchDB1. The solution must meet the security and compliance requirements.
What should you include in the plan?
You have an Azure subscription that contains two Azure SQL managed instances named SQLMI1 and SQLMI2 . SQLM2 contains a database named DB1 and a user named User1.
User1 drops DB1.
You need to perform a point-in-time restore of DB1 to SQLMI2.
You have an Azure SQL database that contains a table named factSales. FactSales contains the columns shown in the following table.
FactSales has 6 billion rows and is loaded nightly by using a batch process.
Which type of compression provides the greatest space reduction for the database?
Columnstore tables and indexes are always stored with columnstore compression. You can further reduce the size of columnstore data by configuring an additional compression called archival compression.
Note: Columnstore --- The columnstore index is also logically organized as a table with rows and columns, but the data is physically stored in a column-wise data format.
Incorrect Answers:
B: Rowstore --- The rowstore index is the traditional style that has been around since the initial release of SQL Server.
For rowstore tables and indexes, use the data compression feature to help reduce the size of the database.

You have a single availability set that contains two SQL Server on Azure Virtual Machines instances.
The instances were deployed by using an Azure Marketplace SQL Server 2019 Enterprise image that has the latest cumulative updates applied. The instances are configured as the nodes of a failover cluster instance (FCI) named FCI1.
You need to ensure that client applications can connect to FCI1. The solution must meet the following requirements:
* Provide an availability SLA
* Minimize costs.
What should you create?
You need to recommend an availability strategy for an Azure SQL database. The strategy must meet the
following requirements:
Support failovers that do not require client applications to change their connection strings.
Replicate the database to a secondary Azure region.
Support failover to the secondary region.
What should you include in the recommendation?
Active geo-replication is an Azure SQL Database feature that allows you to create readable secondary databases of individual databases on a server in the same or different data center (region).
Incorrect Answers:
C: Availability Zones are unique physical locations within a region. Each zone is made up of one or more
datacenters equipped with independent power, cooling, and networking.
