                                                                                            NEW QUESTION # 121
                                                                                            You have an Azure SQL database named DB1. DB1 has a table named Table1 that contains the following columns.

                                                                                            You plan to enable Always Encrypted for Table1.
                                                                                            Which two columns support encryption? Each correct answer presents a complete solution.
                                                                                            NOTE: Each correct selection is worth one point

                                                                                            Answer: D,E

                                                                                            Explanation:
                                                                                            Basic Concept: This question tests secure database administration, where the control must match the data state, access boundary, identity model, or compliance requirement.
                                                                                            Why A and D is Correct: Column1 is correct because it is the feature whose normal purpose matches the stated requirement. Column1 is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. The scenario wording points to that specific behavior: Which two columns support encryption? Column4 is correct because it is the feature whose normal purpose matches the stated requirement. Column4 is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. The scenario wording points to that specific behavior: Which two columns support encryption?
                                                                                            Why B is Wrong: Column2 is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It does not satisfy the required identity, encryption, firewall, auditing, or data-exposure boundary described in the scenario: Which two columns support encryption?
                                                                                            Why C is Wrong: Column3 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 E is Wrong: Column5 is a security-related control, but its value depends on whether the requirement is identity, encryption, auditing, network isolation, or data exposure reduction. It does not satisfy the required identity, encryption, firewall, auditing, or data-exposure boundary described in the scenario: Which two columns support encryption?

                                                                                            You discover that all Microsoft SQL Server integration Services (SSIS) packages fail to run on the virtual machine.
                                                                                            Which four actions should you perform in sequence to resolve the issue? To answer, move the appropriate actions from the list of actions to the answer area and arrange them in the correct.
