ServiceNow CIS-DF IRE Reconciliation Rules Practice Test

Topic 03 focuses on IRE Reconciliation, Data Source, and Dependency Rules for the ServiceNow Certified Implementation Specialist – Data Foundations (CMDB and CSDM) certification and the CIS-DF exam, using ServiceNow CMDB and Common Service Data Model (CSDM) implementation scenarios. For broader exam preparation, review the ServiceNow CIS-DF Exam Dumps page. Each question includes a concise explanation of the correct answer and the technical reason the other choices are incorrect.

Question 1

A team plans to use Attribute-level source precedence. Which outcome aligns with its intended purpose?

1. To identify dependent CIs using their relationship to a hosting or parent CI.
2. To block untrusted sources from creating new CIs without blocking all updates.
3. To handle a CI class change that requires administrator review.
4. To select the preferred source for a specific CI attribute.

Correct Answer: D

 

Correct Answer

Answer D is correct because Attribute-level source precedence orders discovery sources for a particular attribute so higher-priority sources take precedence during reconciliation.

Incorrect Answers

Answer A is incorrect because that outcome is associated with Dependent relationship rule, not Attribute-level source precedence.

Answer B is incorrect because that outcome is associated with IRE data source rule, not Attribute-level source precedence.

Answer C is incorrect because that outcome is associated with Reclassification task, not Attribute-level source precedence.

 

Question 2

1. Reconciliation rule inheritance
2. Authoritative discovery source
3. Attribute-level source precedence
4. Data refresh rule

Correct Answer: B

 

Correct Answer

Answer B is correct because Authoritative discovery source matches the described capability and is used to ensure trusted sources control the attributes for which they are responsible.

Incorrect Answers

Answer A is incorrect because Reconciliation rule inheritance is intended to reuse parent-class data-governance rules across related child classes, which does not match the described function.

Answer C is incorrect because Attribute-level source precedence is intended to select the preferred source for a specific CI attribute, which does not match the described function.
