5. What do you mean by data lookup and record matching?
Data lookup and record matching feature helps to set a field value based on some condition instead of writing scripts.

On Incident forms, the priority lookup rules sample data automatically. Then, set the incident Priority based on the incident Impact and Urgency values. Data lookup rules allow to specify the conditions and fields where they want data lookup to occur.
6. What is CMDB Baseline?
CMDB Baselines will help you, understand and control the changes made to a configuration Item(CI). These Baselines act as a snapshot of a CI.

10. What do you mean by impersonating a user? How it is useful?
Impersonating a user means giving the administrator access to what the user would have access to. This includes the same menus and modules. ServiceNow records the administrator activities when the user impersonates another user. This feature helps in testing. You can impersonate that user and can test instead of logging out from your session and logging again with the user credentials.
11. Explain the steps for enabling or disabling an application in ServiceNow.

12. Explain record matching and data lookup features in ServiceNow.
The data lookup and record matching features allow you for setting up the field value based on a particular condition instead of scriptwriting.

Data lookup rules allow you to specify the fields and conditions where you wish data lookup to happen.
