Practice Test
True or False: Business rules always run on the client-side, not the server-side.
- True
- False
Answer: False
Explanation: Business rules can run both client-side and server-side. They are designed to provide a simplified interface for defining business logic, that can then be executed from the client or the server.
True or False: Client scripting is typically used for form customization and validation.
- True
- False
Answer: True
Explanation: Client scripting is often used for tasks such as form customization, data manipulation, and field validation. It is run directly in the user’s browser.
Multiple Select: Which of the following are benefits of using business rules?
- a) Easy to implement
- b) Do not require knowledge of JavaScript
- c) Can be run on both client-side and server-side
- d) Business rules are useful for complex business logic
Answer: a, b, and c
Explanation: Business rules are easy to implement, do not require knowledge of JavaScript, and can be run on both client-side and server-side. While they are useful for basic business logic, for complex logic, other methods such as plugins or workflows are recommended.
Single Select: When you need to create a complex business process, which is typically the best to use?
- a) Client scripting
- b) Business rules
- c) Plugins
- d) Workflows
Answer: c) Plugins
Explanation: For complex business processes, plugins are typically the best choice because they offer more flexibility and can handle more complex operations.
True or False: Client scripting can also be used for server-side operations.
- True
- False
Answer: False
Explanation: Client scripting specifically refers to scripts that are run on the client-side, or in the user’s browser.
Single Select: Which is more suitable for basic form validation?
- a) Business rules
- b) Client scripting
- c) Server-side scripting
- d) Workflows
Answer: b) Client scripting
Explanation: Client scripting is well-suited to tasks like data manipulation and form validation.
True or False: Business rules continue to function even if the user has disabled JavaScript in their browser.
- True
- False
Answer: True
Explanation: Business rules, being server-side, do not depend on the user’s browser settings and will function regardless of whether JavaScript is enabled or not.
Multiple Select: Which of the following scenarios are suitable for using Client scripting?
- a) Data manipulation
- b) Form customization
- c) Complex business logic
- d) Simple data validation
Answer: a, b, and d
Explanation: Client scripting is well suited to tasks such as form customization, data manipulation and simple data validation. It is not typically used for complex business logic.
Single Select: Which is better to use when quick performance is required?
- a) Client scripting
- b) Business rules
- c) Server-side scripting
- d) Workflows
Answer: a) Client scripting
Explanation: Since client scripting runs directly on the user’s browser, it generally provides quicker performance as compared to server-side operations.
True or False: Business rules do not allow for any sort of scripting.
- True
- False
Answer: True
Explanation: Business rules are a no-code feature of the Power Platform. This means they provide a graphical interface to define business logic, rather than requiring a script to be written.
Interview Questions
What is a Business Rule in Microsoft Power Platform?
In Microsoft Power Platform, a business rule is a declarative rule defined within a Common Data Service entity to provide server-side logic for data manipulation.
What is Client Scripting in Microsoft Power Platform?
Client scripting in Microsoft Power Platform involves writing JavaScript code that executes in response to form events, such as a field changing value or the form loading.
When might it be better to use a business rule rather than client scripting in Microsoft Power Platform?
Business rules could be better when the logic is simple and needs to be enforced consistently across all platforms. As business rules are server-side, they are executed regardless of the client.
When would client scripting be preferable over business rules in Microsoft Power Platform?
Client scripting may be a better choice if your logic is complex, requires interaction with users, or needs to be executed promptly in response to form events.
Do business rules or client scripting execute first in form events in Microsoft Power Platform?
Business rules execute before client scripting when a form loads.
Can business rules be used with an offline client in Microsoft Power Platform?
Yes, business rules also apply in an offline client as long as the client has synchronized with the server.
Can client scripting be used with an offline client in Microsoft Power Platform?
Yes, however, not all client-side code will function as expected offline. It requires careful design and testing to implement offline-compatible client scripting.
Can business rules work with other entities in Microsoft Power Platform?
No, business rules can only operate within the scope of a single entity.
How many actions or conditions can a business rule have in Microsoft Power Platform?
There is no defined limit to the number of conditions or actions that a business rule can have. However, complex business rules might affect system performance.
Can a business rule set field values in Microsoft Power Platform?
Yes, business rules can set field values, show or hide fields, enable or disable fields, and validate data and show error messages.
Can client scripting get or set lookup value in Microsoft Power Platform?
Yes, client scripting can get or set lookup value using Xrm.Page.data.entity.attributes.get and Xrm.Page.data.entity.attributes.set methods.
What happens when a business rule and client script conflict in Microsoft Power Platform?
The result is unpredictable and depends on the sequence of execution. It is recommended to avoid such conflicts.
Can client scripting interact with web resources on a form in Microsoft Power Platform?
Yes, client scripting can interact with web resources on a form. For example, the script can get a reference to an iframe or a web resource control on the form.
Can a business rule interact with web resources on a form in Microsoft Power Platform?
No, business rules cannot interact with web resources on a form.
Can business rules and client scripting coexist on the same form in Microsoft Power Platform?
Yes, business rules and client scripting can coexist on the same form, but care must be taken to avoid conflicts or unexpected behavior.
