2) What is an ‘Application’ in ServiceNow?

Applications in ServiceNow represent packaged solutions for delivering services and managing business processes. In simple words it is a group of modules which provides information related to those modules. For example Incident application will provide information related to Incident Management process.

3) What is full form of CMDB and what is it?

CMDB stands for Configuration Management Database. CMDB is a repository. It acts as a data warehouse for information technology installations. It holds data related to a collection of IT assets, and descriptive relationships between such assets.

4) What is LDAP Integration and its use?

LDAP is Light weight Directory Access Protocol. You can use it for user data population and user authentication. ServiceNow integrates with LDAP directory to streamline the user log in process and to automate the creation of user and assigning them roles.

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.

For example:

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.

7) How to enable or disable an application in ServiceNow?

Following steps will help you do the same:

• Navigate to “Application Menus” module
• Open the respective application.
• Set value for active as ‘true’ to enable it or set it to ‘false’ to disable it.

8) What is a view?

View defines the arrangement of fields on a form or a list. For one single form we can define multiple views according to the user preferences or requirement.

9) What is ACL?

An ACL is access control list that defines what data users can access and how they can access it in ServiceNow.

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.

Intermediate ServiceNow Interview Questions

11) What are dictionary overrides?

Dictionary overrides provide the ability to define a field on an extended table differently from the field on the parent table. For example, for a field on the Task [task] table, a dictionary override can change the default value on the Incident [incident] table without affecting the default value on Task [task] or Change [change].

12) What do you mean by coalesce?

Coalesce is a property of a field that we use in transform map field mapping. Coalescing on a field (or set of fields) lets you use the field as a unique key. If a match is found using the coalesce field, the existing record will be updated with the information being imported. If a match is not found, then a new record will be inserted into the database.

13) What are UI policies?

UI policies dynamically change information on a form and control custom process flows for tasks. UI policies are alternative to client scripts. You can use UI policies to set mandatory fields,which are read only and visible on a form. You can also use UI policy for dynamically changing a field on a form.

14) What is a data policy?

With data policies, you can enforce data consistency by setting mandatory and read-only states for fields. Data policies are similar to UI policies, but UI policies only apply to data entered on a form through the standard browser. Data policies can apply rules to all data entered into the system, including data brought in through email, import sets or web services and data entered through the mobile UI.

44) Can you update a record without updating its system fields(like sys_updated_by, sys_updated_on)?

Yes, you can do it by using a function autoSysFields() in your server side scripting. Whenever you are updating a record set the autoSysFields() to false.

Consider following Example:

var gr = new GlideRecord(‘incident’);
gr.query();
if(gr.next()){
gr.autoSysFields(false);
short_description = “Test from Examsmyntra” ;
