You plan to deploy an Always On availability group that will have the following configurations:
VM1 will host the primary replica of DB1.
VM2 will host a secondary replica of DB1.
You need to prepare the secondary database on VM2 for the availability group.

NEW QUESTION # 244
You are designing an enterprise data warehouse in Azure Synapse Analytics that will contain a table named Customers. Customers will contain credit card information.
You need to recommend a solution to provide salespeople with the ability to view all the entries in Customers.
The solution must prevent all the salespeople from viewing or inferring the credit card information.
What should you include in the recommendation?
Answer: B
Explanation:
Azure SQL Database, Azure SQL Managed Instance, and Azure Synapse Analytics support dynamic data masking. Dynamic data masking limits sensitive data exposure by masking it to non-privileged users.
The Credit card masking method exposes the last four digits of the designated fields and adds a constant string as a prefix in the form of a credit card.
Example:
XXXX-XXXX-XXXX-1234
Basic Concept: This question tests secure database administration, where the control must match the data state, access boundary, identity model, or compliance requirement.
Why B is Correct: data masking matches the expected DP-300 administration action. data masking is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. 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 provide salespeople with the ability to view all the entries in Customers.
Why A is Wrong: Row-Level Security filters rows returned by queries based on a predicate function, allowing different users or tenants to see different subsets of the same tables. 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 C is Wrong: Always Encrypted protects sensitive columns from exposure to the database engine by encrypting and decrypting data at the client side with keys protected outside the database. It protects or manages a different security layer, so the required database access or protection behavior would still be incomplete.
Why D is Wrong: column-level security 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.
