CTA Exam Dumps : ServiceNowCertified Technical Architect (CTA)

The Identification and Reconciliation (I&R) module usesidentification rules to uniquely identify CIs. These rules help the system determine if a CI discovered or imported from a data source already exists in the CMDB or if it's a new CI.

Here's how it works:

Identification Rules:These rules define criteria for matching CIs based on their attributes (e.g., serial number, MAC address, hostname).

Matching and Reconciliation:When new data comes in, the I&R engine applies the rules to find potential matches. If a match is found, the system can either update the existing CI with new information or flag it as a potential duplicate for review.

Why not the other options?

A:While the I&R engine can facilitate merging duplicates, it doesn't automatically merge them without human review and approval.

C:Data source validation is important, but it's not the primary function of the I&R engine in duplicate reduction.

D:Assigning unique identifiers is a function of the CMDB itself, not specifically the I&R engine.

Key governance factors for release and instance management include:

B. Operating model and development approach: Define the organization's approach to development (e.g., Agile, Waterfall), release cycles, and how different teams collaborate on the platform.

C. Platform scope and deployed applications: Clearly define the scope of the ServiceNow platform within the organization and the applications that will be deployed. This helps with planning and resource allocation.

E. Number and purpose of instance environments: Establish a clear instance strategy, including the number of instances (dev, test, prod, etc.), their purpose, and how they are used to support development and deployment processes.

Why not the other options?

A. Release performance and instance usage analytics: While these are important for monitoring and optimization, they are not primary governance factors.

D. Day-to-day instance performance metrics: These are operational metrics, not directly related to governance decisions.

In the context of ServiceNow technical governance, environmental management primarily focuses on defining the instance structure. This includes:

Instance Segmentation: Determining how many instances are needed (e.g., separate instances for development, test, and production) and how they relate to each other.

Instance Upgrades: Establishing policies and procedures for managing instance upgrades, including scheduling, testing, and communication.

Instance Maintenance: Defining guidelines for ongoing maintenance activities, such as patching, backups, and performance monitoring.

Why not the other options?

B. Data ownership: Data ownership is typically addressed within data governance policies, not specifically environmental management.

C. User access policies: User access policies are part of security governance and are handled through roles, permissions, and access control lists.  

D. Application customization: Application customization is governed by development and configuration standards, not directly by environmental management.
