False is correct.

Microsoft does not guarantee 100 percent availability for Azure SQL Database. The service is covered by a published service level agreement that guarantees a high but not perfect uptime percentage and the SLA defines conditions for breaches and service credits rather than promising absolute availability.

You can improve resilience by using built in redundancy and failover features and by architecting for geo or zone redundancy. Those designs can raise practical availability but they do not change the fact that the vendor SLA specifies a percentage below 100 percent.

True is incorrect because it asserts that Microsoft guarantees complete availability. The official SLA for Azure SQL Database provides a specific uptime percentage and conditions for credit but it does not promise one hundred percent uptime.
