Designing Azure Infrastructure Solutions — Question 40

You need to design a highly available Azure SQL database that meets the following requirements:

• Failover between replicas of the database must occur without any data loss.
• The database must remain available in the event of a zone outage.
• Costs must be minimized.

Which deployment option should you use?

Answer options

Correct answer: B

Explanation

The Azure SQL Database Business Critical option provides high availability with no data loss during failover and supports zone redundancy to maintain availability during outages. The other options do not meet the requirements for no data loss or adequate zone resilience, and may not offer the same level of performance and reliability needed for critical applications.
