It is a cloud-based IT Service Management tool. ServiceNow gives a solitary plan of record for IT administrations, activities, and business administration via computerizing IT benefit applications and procedures. All parts of IT Services can possibly live in the ServiceNow biological system of modules, and in this manner, it gives us a total perspective of administrations and assets. This takes into account wide control of how to best designate assets and plan the procedure stream of those administrations.
Now let's have a look into the Servicenow Developer,Servicenow Admin and Servicenow Scripting Interview Questions for all levels of expertise.
Ans: Task table is the parent table for the incidents, change and problem.
Ans: A record producer is a type of a catalog item that allows users to create task-based records from the service catalog. For example, you can create a change record or problem record using a record producer. Record producers provide an alternative way to create records through a service catalog.
Ans: Dictionary Overrides provides the capability to override several properties of a field in the extended table.For example, change table is extended from task table.There is a field named status in task table and set as read-only.When we use this field in change form it will show be read-only.We can set this to non-read only by using the dictionary override. Similarly, there are other properties that can be set for the fields in an extended table.

Ans: UI policies are alternative to client scripts.It can be used to set a field as mandatory, read-only and visible on a form. You can also use UI policy for dynamically changing a field on a form.
Ans: Data policy checks the mandatory and read-only of a field whenever a record is inserted or updated through a web-service or import set. For example: If a mandatory field in the incoming record (from import set or web-service) is empty then the data policy will not allow inserting that record into the table.
Ans: Client script sits on the client side(the browser) and run there only.types of client script are OnLoad() OnSubmit() OnChange() OncellEdit()
Ans:In the onSubmit function return false. function onSubmit() { return false; }
Ans: The business rule is server-side scripting that executes whenever a record is inserted, updated, deleted, displayed or queried.The key thing to keep in mind while creating a business rule is that when and on what action it has to execute. You can run the business rule ‘on display’, ‘on before’ or ‘on after’ of an action (insert, delete, update) is performed.
Ans: Yes you can call a business rule through a client script by using glideajax
Ans: Gliderecord is a java class that is used for database operations instead of writing SQL queries.

Ans: Import Sets is a tool used to import data from various data sources and, then using transform map, the map that data into ServiceNow tables. The Import Sets table acts as a staging table for records imported.
Ans: The ServiceNow® Change Management application provides a systematic approach to control the life cycle of all changes, facilitating beneficial changes to be made with minimum disruption to IT services.
ServiceNow Change Management integrates with the Vulnerability response plugin to introduce extra functionality within Change Management.

Ans: A transform map transforms the record imported into ServiceNow import set table to the objective table. It additionally decides the connections between fields showing in an Import Set table and fields in the target table.
Ans: A foreign record insert occurs when an import makes a change to a table that is not the target table for that import. This happens when updating a reference field on a table.
Ans: Zing is the text indexing and search engine that performs all text searches in ServiceNow.
Ans: The Client Transaction Timings plugin enhances the system logs by providing more information on the duration of transactions between the client and the server. By providing information on how time was spent during the transaction, performance issues can be tracked down to the source by seeing where the time is being consumed.
Ans: An inactivity monitor triggers an event for a task record if the task has been inactive for a certain period of time. If the task remains inactive, the monitor repeats at regular intervals.
Ans: Domain separation is a way to separate data into (and optionally to separate administration by) logically-defined domains.
For example, A client XYZ have two business and they are using ServiceNow single instance for both businesses.They do not want that user’s from one business can see data of other business.Here we can configure domain separation to isolate the records from both businesses.
Ans: You can set the property – “glide.ui.forgetme” to true to remove the Remember me checkbox from the login page.
Ans: The HTML sanitizer automatically cleans up HTML markup in HTML fields to remove unwanted code and protect against security concerns such as cross-site scripting attacks. The HTML sanitizer is active for all instances starting with the Eureka release.
Ans: A gauge can be based on a report and can be put on a homepage or a content page.
Ans: Metrics tracks and monitors the workflow of individual records. With metrics, consumers may arm their mechanism by having tangible statistics to calculate, for example, how long it takes before a ticket is reassigned or the state changes.

Ans:To find information in ServiceNow, use any of the following searches:
Ans: Each update set is stored in the Update Set [sys_update_set] table, and the customizations that are associated with the update set, are stored in [sys_update_xml] table.
Ans: In any case, the default update set is marked as complete when the device generates an alternative update called Default1 and uses it to update the set.
Ans: Homepages and content pages are not added to change settings by default. You need to manually connect pages to the latest update collection by unloading them.
Ans: Reference Qualifiers are used to limit the data that can be chosen for the reference area.
Ans:Performance Analytics is an additional technology in Operation Now that enables customers to take a snapshot of the data at regular intervals and to create time series for every main performance indicator (KPI) in the enterprise.
Ans: Coalesce is a field property that we use to map the map field to transform. When we set the coalesce to be valid for field mapping, it means that this field will function as a unique key. If a match field is identified with the coalesce field,the current record will be updated with the imported information in the target table,otherwise a new record will be added to the target table.
Ans: An ACL is Access Control List that defines what data a user can access and how they can access it in service now.
Ans: CMDB baselines help to understand and control the changes that have been made to a Configuration Item (CI) after its Baseline has been created. The baseline is the snapshot of a CI.
Ans: Navigate to “Application Menus” module under system definition application. Open the respective application that requires enabling or disabling. Set active as true to enable it or set active to false to disable it.
Ans: View characterizes the game plan of fields on a frame or a rundown. For one single shape, we can characterize different perspectives as indicated by the client inclinations or prerequisite.
Ans:
Ans: The application is a group of modules which provides its related information. For example,change application provides the information related to change process. It consists of modules like create change ticket, view change tickets etc.
Ans: Impersonating a user means that you can log in to the system as that user and can have felt how the servicenow UI is set for that user. This is very useful while testing. For example, if you are required to test that a user can access change form or not. You can impersonate that user and can test instead of logging out from your session and logging again with that user credentials.
Ans: Task table
Ans: In the onSubmit function return false.
function onSubmit()
