To activate or deactivate an application in ServiceNow, follow the steps below:

To get started, go to the “Application Menus” module.

Launch the application that needs to be activated or deactivated.

To enable the application, change the active value to “true.” Change the active value to “false” to disable the program.

7. Define CMDB Baseline, and how does it work?

After a Baseline has been produced, CMDB baselines allow us to understand and regulate the modifications implemented to a configuration item (CI). The baseline is a CI snapshot.

8. Define LDAP Integration and how does it work?

The LDAP acronym stands for Lightweight Directory Access Protocol. It may be used to populate user data and authenticate users. ServiceNow interfaces with the LDAP directory to automate the creation of users, give them roles and optimize the user log-in procedure.

9. Define LDAP Integration and how does it work?

The LDAP acronym stands for Lightweight Directory Access Protocol. It may be used to populate user data and authenticate users. ServiceNow interfaces with the LDAP directory to automate the creation of users, give them roles and optimize the user log-in procedure.

10. Explain what a “business rule” is?

Server-side scripting is the business rule. It runs when a record is inserted, changed, removed, displayed, or queried. The most important thing to remember when establishing a business rule is when and how it should be executed. When an action is completed, you may use the business rule ‘on display,’ ‘on before,’ or ‘on after.’

11. Is it feasible to invoke a business rule using a client script?

Yes. Using glide ajax, we can invoke a business rule from a client script.

12. What does ServiceNow mean by Coalesce?

Coalesce is a field characteristic that is utilized in transform map field mapping. You may use it as a unique identifier when you coalesce on a field. When a similarity with the coalesce field is discovered, the current record will be modified with the imported data. If you cannot locate a match, a new record will be inserted into the database.

13. Define view?

The view determines how fields on a form or list are organized. We may design various views for the same form based on the user’s preferences or requirements.

14. Define ACL?

An access control list (ACL) in ServiceNow determines what data users have access to and how they may access it.

15. In ServiceNow, what is domain separation?

Domain separation is an effective ServiceNow technique. It aids in the division of data into logically defined areas. It also allows for administration to be separated.

For instance, Joseph is the Chairman of two firms, and he uses a single instance of ServiceNow for both. He does not want users from one firm to be able to see data from another. To keep the data from both firms separate, you’ll need to employ domain separation.

16. What exactly do you mean by Dictionary Override?

An extended table or field is differentiated from its parent table’s area via a dictionary override. For a better understanding, consider the following example:

For example, we may alter the default value on the incident table without modifying the value on the change or task table field by using a dictionary override for a task table field. The significant advantage of the dictionary overrides this.

17. What does it mean to impersonate a user? What is the benefit of it?

Giving the administrator access to what the genuine user would have access to is known as impersonating a user. This will feature the same modules and menus as the previous version. When a user impersonates another user, ServiceNow captures all of the administrator’s activity. This ServiceNow functionality is handy for testing. For instance, if you want to see whether or not a user can access the change form. You have permission to impersonate that user and undertake testing without logging out of your session and logging back in using that user’s credentials.

18. Which is the incident, change, or problem’s parent table?

Task Table.

19. What do UI policies entail?

UI policies govern custom task process flows and dynamically update information on a form. Client scripts can be replaced with UI policies. Mandatory fields, which are read-only and displayed on a form, maybe defined using UI policies. You may also use UI policy to dynamically change a field on a form.

20. Make a list of recommended practices to follow when utilizing ServiceNow?

Here are some best practices to keep in mind while utilizing ServiceNow:

• Collaborative workplaces should take the role of spreadsheets and email.

• Every business procedure in your company should be automated.

• ServiceNow makes it simple to create a contemporary work environment.

• To speed service delivery, you should attempt to improve, structure, and automate the workflow.|

21. In ServiceNow, what is a data policy?

Data policies in ServiceNow are pretty comparable to UI policies. By giving read-only characteristics to all fields, Data Policies make it easier for a developer to implement online data policies.

The following are some critical distinctions between data policy and user interface policy:

• Only data input on a form using a standard browser is covered by the UI policy. On the other hand, data policies might apply rules to any input fed into the system.

• Data Policies, unlike UI Policies, run on the server.

• Developers cannot apply scripts to Data Policies because UI Policy logic only applies to data input in a form.

22. In ServiceNow, what is a transform map?

In ServiceNow, a transform map is a field map set that governs the connection between the shown fields in the import set table and the existing fields in the destination table, such as “detectHand”:false or “detectHand”:false.

After creating the transform map, you may use it to map data from another import set to the same table.
An administrator can use a transform map to specify the end destinations for data loaded into tables. This will make establishing connectivity between the source fields of the import set table and the destination fields of the target table easier.
Transform mapping allows you to map source and destination fields arbitrarily.

23. What is the role of a record producer?

Users can construct task-based records from the service catalog using a record producer, which is a form of the catalog item. A record producer, for example, can be used to generate a change or problem record. Through the service catalog, record producers offer an option for making albums.

24. What is the definition of a client script?

Client scripts reside on the client-side (the browser) and are only used by the client. The following are the different kinds of client scripts:
• OnLoad()
• OnSubmit()
• OnChange()
• OncellEdit)

25. How many different sorts of search options does ServiceNow provide?

In ServiceNow, there are five different sorts of search options:

• To locate records in a list, use lists.

• Global Text Search: You may find records in many task tables from a single search field.

• Knowledgebase: Assists in the discovery of knowledge articles.

• Filter the objects in the application navigator with the navigation filter.

• Search scenes: This is a unique module that only administrators may develop.

26. How can a client script cancel a form submission?

The onSubmit method should return false if you wish to cancel a form submission through the client script. To cancel a form submission using a client script, use the code below:

function onSubmit() { return false; }

27. In ServiceNow, what is the import set?

The import set tool is used to import data from several data sources, subsequently transformed into ServiceNow tables using transform maps. It acts as a staging area for imported data.

28. Define Gliderecord?

Gliderecord is a java class used for database operations rather than writing SQL queries.

29. What exactly do you mean when you say “foreign record insert”?

When an import changes a table that is not the intended table for that import, this is referred to as a foreign record insert. This occurs when a table’s reference field is updated.

30. What is HTML Sanitizer’s purpose?

HTML sanitizer cleans up a markup in HTML fields automatically. It aids in the removal of code and the prevention of security issues like cross-site scripting attacks.
