NEW QUESTION # 238
You have an Azure subscription that contains the resources shown in the following table.

You plan louse SQLDB11 as an elastic job database to run jobs on SQlDb11 andSOtDB22. What is the minimum number of database scoped credentials required tor the elastic jobs?

A. 0
B. 1
C. 2
D. 3

Answer: C

Explanation:
Basic Concept: This question tests task automation for database administration, including which Azure or SQL mechanism can run repeatable maintenance and configuration work.
Why B is Correct: 2 matches the expected DP-300 administration action. 2 can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. The question is not asking for a general Azure capability; it is asking for the feature that produces this result: What is the minimum number of database scoped credentials required tor the elastic jobs?
Why A is Wrong: 1 can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. It belongs to a different step of operations; this question needs the mechanism that can run or deploy the task repeatedly.
Why C is Wrong: 3 can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. It does not provide the required repeatable execution, scheduling, or deployment automation requirement, so it would not complete the administrative workflow reliably.
Why D is Wrong: 4 can participate in administration workflows, but automation questions require the mechanism that can execute repeatable tasks with the correct scope and schedule. It belongs to a different step of operations; this question needs the mechanism that can run or deploy the task repeatedly.
