3. What is Protection Policy ?
-> The Protection Policy is used to safeguard backend configurations and script logic from being edited. It makes configurations and customizations read-only or protected within the system.
For scripts such as Business Rules, Script Includes, Client Scripts, UI Policies, and Data Policies, Application Files, UI Builder , Flow designer action, Scripted REST API. There is a field called Protection Policy and this field can be set to Read-only, Protected, or left Empty.
We can apply protection policy for on custom script as well.

4. Any idea about multitenant instance (Domain Separation) in ServiceNow ?
->
With domain separation you can separate data, processes, and administrative tasks into logically defined domains.
Domain separation is best for those customers who:
- Need to enforce absolute data segregation between business entities (data separation).
- Customize business process definitions and user interfaces for each domain (delegated administration).
- Maintain some global processes and global reporting in a single instance.
- Separate data between service providers, customers, partners, or sub-organizations.
A domain hierarchy is a structure of domains within an instance.
Domain Hierarchy – > Establish the Parent/child relationship between domainsSystem policy functions can be defined globally or specifically for a particular domain. The layouts of forms, lists, related lists, and choice lists can also be domain-specific.
