You have an Azure virtual machine named VM1 that runs Windows Server 2022 and hosts a Microsoft SQL Server 2019 instance named SQL1. You need to configure SQL! to use mixed mode authentication. Which procedure should you run?
Correct Answer: B
Basic Concept: This question tests identity and authentication for Azure SQL and SQL Server workloads, including when to use contained users, directory identities, certificate validation, or authentication profiles.
Why B is Correct: xp_instance_regwrite matches the expected DP-300 administration action.
xp_instance_regwrite is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: You need to configure SQL! to use mixed mode authentication.
Why A is Wrong: sp_addremoteIogin is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
Why C is Wrong: sp_cnarge_users_login is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It is not wrong technology in general, but it is the wrong HA/DR control for this scenario ' s failure model.
Why D is Wrong: xp_grant_login is part of the availability or recovery design space, but the correct choice must satisfy the specified failover, restore, quorum, RPO, or RTO requirement. It does not meet the failover, restore, quorum, or cross-region continuity target stated in the question, even if it is valid in a different availability design.
