The primary factor in determining the number of MID Servers needed is the number of targets and interaction frequency.

Targets: The number of devices, applications, or external systems that ServiceNow needs to interact with (e.g., for discovery, orchestration, integrations).

Interaction Frequency: How often ServiceNow needs to communicate with these targets (e.g., continuous monitoring, scheduled data imports).

Why not the other options?

A. The number of network routers in use: While network infrastructure is important, it's not the primary factor for MID Server sizing.

C. The number of concurrent users on the instance: User activity impacts application server load, not directly the number of MID Servers needed.

D. The geographical spread of the organization: Geographic spread can influence MID Server placement, but the primary factor is the number of targets and interaction frequency.

The most common and recommended way to create new CI classes in ServiceNow is byextending existing classes. This leverages the existing data structure and relationships within the CMDB.

Here's why this approach is preferred:

Inheritance:Extending a class allows the new class to inherit attributes and relationships from the parent class, ensuring consistency and reducing redundancy.

Data Model Integrity:It helps maintain the integrity of the CMDB data model by building upon the established CSDM framework.

Customization:Extending classes provides flexibility to add specific attributes and relationships that are unique to the new CI class.

Why not the other options?

A:While importing data can populate the CMDB, it's not the primary method for creating new CI classes and their relationships.

B:ServiceNow does not offer predefined templates for creating new CI classes.

C:IntegrationHub ETL is a powerful tool for data integration, but it's primarily used for data transformation and loading, not for creating new CI classes.

A 5-stack instance structure (dev, QA, UAT, staging, production) provides several advantages:

A. Staging instance for troubleshooting: The staging instance closely mirrors the production environment, allowing for thorough testing and troubleshooting of changes before they are deployed to production.

C. Deployment testing: Each instance serves a specific testing purpose (QA for functional testing, UAT for user acceptance testing), ensuring comprehensive validation before production deployment.

D. Increased parallel activity: Different teams can work simultaneously in their respective instances, increasing development and testing efficiency.

Why not the other options?

B. Lower maintenance effort: A 5-stack structure can actually increase maintenance effort due to the need to manage multiple instances.

E. Single Dev track: A 5-stack structure typically supports multiple development tracks or branches.
