Questions # 43:

You need to implement authentication for ResearchDB1. The solution must meet the security and compliance requirements.

What should you run as part of the implementation?

Options:

CREATE LOGIN and the FROM WINDOWS clause

CREATE USER and the FROM CERTIFICATE clause

CREATE USER and the FROM LOGIN clause

CREATE USER and the ASYMMETRIC KEY clause

CREATE USER and the FROM EXTERNAL PROVIDER clause

Expert Solution

Answer

Explanation

Scenario: Authenticate database users by using Active Directory credentials.

(Create a new Azure SQL database named ResearchDB1 on a logical server named ResearchSrv01.)

Authenticate the user in SQL Database or SQL Data Warehouse based on an Azure Active Directory user:

CREATE USER [Fritz@contoso.com] FROM EXTERNAL PROVIDER;

[Reference:, https://docs.microsoft.com/en-us/sql/t-sql/statements/create-user-transact-sql, , , , , , , , 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 E is Correct: CREATE USER ... FROM EXTERNAL PROVIDER creates contained users mapped to Microsoft Entra identities for Azure SQL authentication. The scenario asks for: You need to implement authentication for ResearchDB1. That makes CREATE USER and the FROM EXTERNAL PROVIDER clause the option that satisfies the required Azure SQL layer and operational outcome., Why A is Wrong: CREATE LOGIN and the FROM WINDOWS clause is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It is not the right enforcement point for this case; the scenario needs the control that governs the data or identity path being tested., Why B is Wrong: Certificates support encryption and authentication, but the correct certificate-related object depends on whether the task is TLS, Always Encrypted, or user authentication. It does not satisfy the required identity, encryption, firewall, auditing, or data-exposure boundary described in the scenario: You need to implement authentication for ResearchDB1., Why C is Wrong: CREATE USER and the FROM LOGIN clause is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It protects or manages a different security layer, so the required database access or protection behavior would still be incomplete., Why D is Wrong: CREATE USER and the ASYMMETRIC KEY clause is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It is not the right enforcement point for this case; the scenario needs the control that governs the data or identity path being tested., ]

Questions # 47:

You need to recommend a solution to ensure that the customers can create the database objects. The solution must meet the business goals.

Options:

For each customer, grant the customer ddl_admin to the existing schema.

For each customer, create an additional schema and grant the customer ddl_admin to the new schema.

For each customer, create an additional schema and grant the customer db_writerto the new schema.

For each customer, grant the customer db_writerto the existing schema.

Expert Solution

Answer

Explanation

Basic Concept: This question tests plan and configure a high availability and disaster recovery (ha/dr) environment in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.

Why B is Correct: For each customer, create an additional schema and grant the customer ddl_admin to the new schema. matches the expected DP-300 administration action. For each customer, create an additional schema and grant the customer ddl_admin to the new schema. 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 recommend a solution to ensure that the customers can create the database objects.

Why A is Wrong: For each customer, grant the customer ddl_admin to the existing schema. 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 handles a different resilience pattern and would not deliver the failover or recovery behavior required here.

Why C is Wrong: For each customer, create an additional schema and grant the customer db_writerto the new schema. 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 D is Wrong: For each customer, grant the customer db_writerto the existing schema. 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 handles a different resilience pattern and would not deliver the failover or recovery behavior required here.
