SERVICENOW-CIS-DISCOVERY CMDB Integration And Maintenance Practice Test 3 — 15 Questions

Question 1

Which component is responsible for orchestrating the flow of CI data from the discovery source to the CMDB, ensuring data quality?

Accepted Answer

Identification and Reconciliation Engine (IRE). The Identification and Reconciliation Engine (IRE) orchestrates all incoming CI data to ensure it adheres to CMDB rules.

Answer

MID Server

Answer

Discovery Pattern

Answer

CMDB Health Dashboard

Question 2

Which of the following best describes how the CMDB Health Dashboard defines 'Duplicate' CIs?

Accepted Answer

Multiple CIs that share the same identification criteria.. Duplicates are identified based on multiple CIs matching the same criteria defined in the Identification Rules.

Answer

CIs with the same name.

Answer

CIs discovered at the same time.

Answer

CIs that share the same IP address.

Question 3

When a pattern step uses a 'Query' to the target, what is the 'Temporary Variable' used for?

Accepted Answer

To store the output of the step for use in subsequent steps.. A temporary variable is used to store the output of a pattern step so that subsequent steps can access and parse that data.

Answer

To act as a filter for the result set.

Answer

To increase the speed of the scan.

Answer

To define the credentials for the query.

Question 4

Where can you see the 'Discovery Log' for a specific device that was scanned?

Accepted Answer

In the Discovery Status record.. The Discovery Status record contains a related list for 'Discovery Log' which shows all messages for that scan run.

Answer

In the CMDB CI record.

Answer

In the MID Server dashboard.

Answer

In the System Log.

Question 5

If you need to change the priority of a data source for a CI attribute, where do you go?

Accepted Answer

Reconciliation Rules. Reconciliation Rules allow an admin to set the priority (integer value) for each data source for specific attributes.

Answer

Discovery Schedule

Answer

Identification Rules

Answer

Discovery Credentials

Question 6

A business service has become 'inaccurate' in Service Mapping. What is the standard troubleshooting step?

Accepted Answer

Use the 'Debug' mode in Service Mapping.. The Service Mapping interface provides a 'Debug' or 'Check Service' feature to identify which step or dependency failed.

Answer

Upgrade the MID server.

Answer

Re-import the entire CMDB.

Answer

Clear the CMDB cache.

Question 7

Which TWO of the following factors contribute to the CMDB Health Dashboard's 'Completeness' score?

Accepted Answer

Presence of required fields.. Completeness is measured by the presence of required and recommended fields on a CI record.

Answer

Number of duplicate CIs.

Answer

Number of relationships to other CIs.

Answer

Time since last discovery.

Question 8

Which THREE of the following are valid ways to improve the 'Correctness' metric in the CMDB Health Dashboard?

Accepted Answer

Refining identification rules to prevent duplicate CI creation.. Correctness is improved by reducing duplicates and ensuring that identification is reliable.

Answer

Running more frequent discovery scans.

Answer

Adding more fields to the CI classes.

Question 9

Which TWO of the following are common issues that cause the Identification and Reconciliation Engine (IRE) to generate an error?

Accepted Answer

The data source does not have write authority for the CI attributes.. IRE failures often relate to data source authority or non-unique identifier matches.

Answer

The network latency is too high.

Answer

The MID server is offline.

Answer

The CI class is too complex.

Question 10

Which THREE of the following items are considered 'CI Identification' best practices?

Accepted Answer

Keep identification rules as simple as possible to maximize performance.. Best practices for identification focus on stability, uniqueness, and minimizing rule sprawl.

Answer

Create a unique identification rule for every single CI instance.

Answer

Use the CI's 'Name' field as the primary unique identifier.

Question 11

Which TWO of the following are potential side effects of an improperly configured Reconciliation Rule?

Accepted Answer

Legitimate updates are rejected by the system.. Improper rules lead to data flip-flopping or legitimate updates being rejected.

Answer

The Discovery schedule stops.

Answer

MID server credentials are purged.

Answer

The CMDB Health Dashboard crashes.

Question 12

Which TWO of the following actions help reduce 'Staleness' in the CMDB?

Accepted Answer

Ensuring all target devices are covered by a discovery schedule.. Staleness is reduced by ensuring scans run frequently enough and that every CI is targeted by a discovery scan.

Answer

Reducing the number of attributes collected.

Answer

Hardcoding CI attributes manually.

Answer

Adding more classes to the dashboard.

Question 13

Which THREE of the following are components or features that are part of the 'Discovery' to 'CMDB' data pipeline?

Accepted Answer

Discovery Patterns. The pipeline includes data collection (Discovery), processing (IRE), and governance (Reconciliation).

Answer

Incident Management

Answer

Knowledge Management

Question 14

What is the primary function of an 'Identification Rule'?

Accepted Answer

To define the attributes used to match incoming CI data to existing CIs.. An identification rule defines which attributes are used to uniquely identify a CI and match it against existing records.

Answer

To specify which MID server is used.

Answer

To define the scan frequency.

Answer

To map IP ranges.

Question 15

Which THREE of the following are valid CMDB Health metrics?

Accepted Answer

Completeness. The CMDB Health Dashboard specifically tracks Completeness, Correctness, and Compliance (often interpreted as Relationships/Staleness).

Answer

Performance
