Question: 4
You have an Azure SQL database that contains a table named factSales. FactSales contains the columns
shown in the following table.
,Questions & Answers PDF Page 5
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?
A. page compression
B. row compression
C. columnstore compression
D. columnstore archival compression
Answer: D
Explanation:
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.

Question: 5
You have a Microsoft SQL Server 2019 instance in an on-premises datacenter. The instance contains a 4-
TB database named DB1.
You plan to migrate DB1 to an Azure SQL Database managed instance.
What should you use to minimize downtime and data loss during the migration?
A. distributed availability groups
B. database mirroring
C. log shipping
D. Database Migration Assistant
, Questions & Answers PDF Page 6
Answer: A
Explanation:
The Data Migration Assistant (DMA) helps you upgrade to a modern data platform by detecting
compatibility issues that can impact database functionality in your new version of SQL Server or Azure
SQL Database. DMA recommends performance and reliability improvements for your target environment
and allows you to move your schema, data, and uncontained objects from your source server to your
target server.
Note: SQL Managed Instance supports the following database migration options (currently these are the
only supported migration methods):
• Azure Database Migration Service - migration with near-zero downtime.
• Native RESTORE DATABASE FROM URL - uses native backups from SQL Server and requires some
downtime.
