CTA Exam Dumps : ServiceNowCertified Technical Architect (CTA)

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.

To streamline application deployment and ensure consistency across multiple instances, the CTA should prioritize recommending the use of the Application Repository to centralize and distribute custom apps.

Here's why:

Centralized Repository: The Application Repository provides a central location to store and manage custom applications.

Version Control: It allows for versioning of applications, making it easier to track changes and roll back if needed.

Easy Distribution: Applications can be easily published and distributed to other instances from the repository.

Consistency: Using the repository helps ensure that all instances have the same version of an application, promoting consistency and reducing conflicts.

Why not the other options?

A. Use it for a Citizen Development program: While the repository can support citizen development, it's not its primary purpose in this scenario.

B. Employ it for real-time collaborative coding: The repository is not designed for real-time collaborative coding.

D. Use it as a backup for all global application packages: While it can be used for backups, its primary benefit here is for centralized management and distribution.

In the final planning stage of a ServiceNow integration, the CTA should prioritize assessingnetwork and system communication needs. This involves:

Connectivity: Verifying network connectivity between ServiceNow and the external system. This includes checking firewalls, ports, and any required network configurations.

Protocols: Determining the communication protocols to be used (e.g., REST, SOAP, JDBC).

Security: Ensuring secure communication channels, including authentication and encryption requirements.

Performance: Considering bandwidth requirements and potential performance impacts on both systems.

Why not the other options?

B. Determining the color scheme for integration UI: While UI considerations are important, they are not the primary focus during the technical details gathering stage.

C. Planning the communication for the integration go-live: Communication planning is important but separate from the technical details of the integration itself.

D. Estimating the projected integration data metrics: Data volume estimates are useful, but the primary focus is on ensuring successful communication between the systems.
