Question #1
You need to define the data types for the fields of the Non-conformity table. Which two data types should you use? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.
Select 2 answers.
Correct answer: D, E
Explanation
In Business Central, fields in tables are assigned specific data types that determine the kind of data they can store. For the Non-conformity table mentioned in the case study, the following data types should be used: • Date for the Non-Conformity Date field: This is because the Non-conformity Date field is required to store only the date when the non-conformity was recorded. The Date data type is appropriate for storing dates without times. • Code for the Non-Conformity Number field: The Non-conformity Number field is described to use alphanumeric values with a format that includes "NC" and the year, like "NC24-001". In Business Central, the Code data type is used for fields that store alphanumeric keys. It is a text field with a limited length, which makes it suitable for number series that contain letters and numbers. Other options are not suitable: • A. Integer for the Non-conformity Number field: This would not be appropriate because the Non-conformity Number includes alphanumeric characters and not just integers. • B. DateTime for the Non-Conformity Date field: This is not correct because there is no requirement to store the time alongside the date. • C. Char for the Non-Conformity Number field: Char data type is not typically used in Business Central for number series or identifiers. The Code data type is preferred for this purpose.
Question #3
You need to modify the API Customer list code to obtain the required result. For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.

Question #5
A company is deploying Business Central on-premises. The company plans to use a single-tenant deployment architecture.

Each correct answer presents a complete solution. NOTE: Each correct selection is worth one point.
Select 2 answers.
Correct answer: A, B
Explanation
In a single-tenant on-premises deployment each customer has a dedicated Business Central Server instance, and the application objects and the business data are stored together in one database.
