Question 180

For stale rule effective duration, the solution has been deployed. A discovered Linux server is expected to refresh daily; the inherited CMDB Health staleness interval is 60 days and operations need an earlier warning. Which verification best proves it works?

  1. Verify a subsequent source update changes the stale evaluation while leaving the valid CI intact.
  2. Compare per-KPI scorecards before and after remediation to confirm the intended Correctness improvement.
  3. Rerun the completeness job and inspect whether server Required failures decline without changing unrelated rules.
  4. Simulate the last-discovered dates and confirm the Linux subclass becomes stale at the chosen threshold.

Explanation

Correct Answer

D:

This inspects an observable outcome of stale rule effective duration: Simulate the last-discovered dates and confirm the Linux subclass becomes stale at the chosen threshold.

Incorrect Answers

A:

Verify a subsequent source update changes the stale evaluation while leaving the valid CI intact. That check cannot demonstrate simulate the last-discovered dates and confirm the Linux subclass becomes stale at the chosen threshold.

B:

CMDB health checks distinguish missing recommended data from invalid or duplicate CI records. That check cannot demonstrate simulate the last-discovered dates and confirm the Linux subclass becomes stale at the chosen threshold.

C:

CMDB health checks distinguish missing recommended data from invalid or duplicate CI records. Verification of this result involves simulate the last-discovered dates and confirm the Linux subclass becomes stale at the chosen threshold.

Question 181

A discovered Linux server is expected to refresh daily; the inherited CMDB Health staleness interval is 60 days and operations need an earlier warning. The pilot then reports this problem: A host last seen three weeks ago remains healthy because only the 60-day inherited rule is active. Which explanation best identifies the failed mechanism?

  1. Domain-separated recommended-field configurations determine which rules apply to each domain.
  2. Compliance results depend on actual audit execution, unlike a simple Required field check.
  3. The metric counts duplicate CIs in a set as the number of matching records minus one.
  4. The class lacks the required shorter override and therefore uses the base CI rule.

Explanation

Correct Answer

D:

The class lacks the required shorter override and therefore uses the base CI rule.

Incorrect Answers

A:

Recommended CMDB fields measure class-specific data completeness without making the attribute mandatory. The missing change involves the class lacks the required shorter override and therefore uses the base CI rule.

B:

Compliance results depend on actual audit execution, unlike a simple Required field check. That does not establish the class lacks the required shorter override and therefore uses the base CI rule.

C:

CI deduplication depends on stable identifiers and relationships, not just visually matching names. The missing change involves the class lacks the required shorter override and therefore uses the base CI rule.

Question 182

The initial implementation for stale rule effective duration works. A discovered Linux server is expected to refresh daily; the inherited CMDB Health staleness interval is 60 days and operations need an earlier warning. Which governance measure should sustain it?

  1. Coordinate class-specific orphan rules with the approved CMDB relationship design.
  2. Maintain auditable templates and rerun audits after significant configuration changes.
  3. Align class staleness windows to actual data-source schedules rather than using one interval for all technologies.
  4. Document domain-level overrides and avoid assuming all health rules are shared identically.

Explanation

Correct Answer

C:

Align class staleness windows to actual data-source schedules rather than using one interval for all technologies.

Incorrect Answers

A:

Coordinate class-specific orphan rules with the approved CMDB relationship design. That does not establish align class staleness windows to actual data-source schedules rather than using one interval for all technologies.

B:

Maintain auditable templates and rerun audits after significant configuration changes. That does not establish align class staleness windows to actual data-source schedules rather than using one interval for all technologies.

D:

Document domain-level overrides and avoid assuming all health rules are shared identically. That does not establish align class staleness windows to actual data-source schedules rather than using one interval for all technologies.

Question 183

An auditor notices that stale database CIs remain in the CMDB after the staleness scorecard flags them. Which proposed implementation best meets that requirement?

  1. Mark the field Recommended for the appropriate class and use the Recommended completeness metric.
  2. Treat missing dictionary-mandatory values as the Required completeness metric and repair the affected records.
  3. Use the staleness result to initiate source refresh or governed lifecycle review rather than assuming the health metric deletes records.
  4. Configure recommended-field metric rules under the intended domain and verify domain-specific visibility.

Explanation

Correct Answer

C:

Use the staleness result to initiate source refresh or governed lifecycle review rather than assuming the health metric deletes records. The missing change involves using the staleness result to initiate source refresh or governed lifecycle review rather than assuming the health metric deletes records.

Incorrect Answers

A:

CMDB health checks distinguish missing recommended data from invalid or duplicate CI records. That does not use the staleness result to initiate source refresh or governed lifecycle review rather than assuming the health metric.

B:

CMDB health checks distinguish missing recommended data from invalid or duplicate CI records. The missing change involves using the staleness result to initiate source refresh or governed lifecycle review rather than assuming the health metric deletes records.

D:

Recommended CMDB fields measure class-specific data completeness without making the attribute mandatory. The missing change involves using the staleness result to initiate source refresh or governed lifecycle review rather than assuming the health metric deletes records.

Question 184

The implementation team has completed the change for staleness is not deletion. An auditor notices that stale database CIs remain in the CMDB after the staleness scorecard flags them. Which acceptance check should it perform?

  1. Simulate the last-discovered dates and confirm the Linux subclass becomes stale at the chosen threshold.
  2. Check the orphan rule output and map, confirming the CI is current but disconnected from its host.
  3. Run CMDB Health and inspect missing-owner records in the class's Recommended result.
  4. Verify a subsequent source update changes the stale evaluation while leaving the valid CI intact.
  5. Compare per-KPI scorecards before and after remediation to confirm the intended Correctness improvement.

Explanation

Correct Answer

D:

Verify a subsequent source update changes the stale evaluation while leaving the valid CI intact. That distinguishes a functioning staleness is not deletion path from a configuration that was merely entered.

Incorrect Answers

A:

This inspects an observable outcome of stale rule effective duration: Simulate the last-discovered dates and confirm the Linux subclass becomes stale at the chosen threshold. That does not verify a subsequent source update changes the stale evaluation while leaving the valid CI intact.

B:

Check the orphan rule output and map, confirming the CI is current but disconnected from its host. That does not verify a subsequent source update changes the stale evaluation while leaving the valid CI intact.

C:

This inspects an observable outcome of recommended field completeness: Run CMDB Health and inspect missing-owner records in the class's Recommended result. That does not verify a subsequent source update changes the stale evaluation while leaving the valid CI intact.

E:

CMDB health checks distinguish missing recommended data from invalid or duplicate CI records. That does not verify a subsequent source update changes the stale evaluation while leaving the valid CI intact.

Question 185

An auditor notices that stale database CIs remain in the CMDB after the staleness scorecard flags them. A troubleshooter observes: The team expected the staleness scheduled calculation to retire the CI automatically. Which diagnosis fits the evidence?

  1. CMDB Health measures quality; lifecycle changes require a separate governed policy or operation.
  2. Compliance results depend on actual audit execution, unlike a simple Required field check.
  3. The class lacks the required shorter override and therefore uses the base CI rule.
  4. The metric counts duplicate CIs in a set as the number of matching records minus one.

Explanation

Correct Answer

A:

CMDB Health measures quality; lifecycle changes require a separate governed policy or operation.

Incorrect Answers

B:

Compliance results depend on actual audit execution, unlike a simple Required field check. That does not establish cMDB Health measures quality; lifecycle changes require a separate governed policy or operation.

C:

The failure is in the stale rule effective duration path, not simply a reason to rerun an unrelated dashboard. The underlying failure instead involves cMDB Health measures quality; lifecycle changes require a separate governed policy or operation.

D:

CI deduplication depends on stable identifiers and relationships, not just visually matching names. The underlying failure instead involves cMDB Health measures quality; lifecycle changes require a separate governed policy or operation.

Question 186

During handoff for staleness is not deletion, An auditor notices that stale database CIs remain in the CMDB after the staleness scorecard flags them. What preventive control should be retained?

  1. Keep quality detection separate from explicit retire/archive/delete authorization.
  2. Treat the three KPIs independently in plans and report which underlying metric changed.
  3. Review which nonmandatory fields are high-value for each class before setting the recommendation policy.
  4. Resolve duplicate tasks with source and relationship review instead of deleting arbitrary sys_ids.

Explanation

Correct Answer

A:

The recurring risk is controlled by Keep quality detection separate from explicit retire/archive/delete authorization. It preserves the staleness is not deletion decision when data sources, policies or operational owners change.

Incorrect Answers

B:

Treat the three KPIs independently in plans and report which underlying metric changed. It would leave keep quality detection separate from explicit retire/archive/delete authorization without the specified safeguard.

C:

Review which nonmandatory fields are high-value for each class before setting the recommendation policy. It would leave keep quality detection separate from explicit retire/archive/delete authorization without the specified safeguard.

D:

CI deduplication depends on stable identifiers and relationships, not just visually matching names. The missing change involves keep quality detection separate from explicit retire/archive/delete authorization.

Question 187

Three independent server CIs match an identification rule and represent a single physical server. An architect must choose the implementation rather than a reporting workaround. Which option fits?

  1. Investigate the Orphan correctness metric, not Staleness, for the missing topology connection.
  2. Use suitable CMDB Health inclusion rules to restrict evaluation to classes and records in scope.
  3. Review the relationship health duplicate metric and de-duplicate identical parent/child/type edges.
  4. Use the correctness Duplicate metric to identify the excess records and start a reviewed de-duplication task.

Explanation

Correct Answer

D:

CI deduplication depends on stable identifiers and relationships, not just visually matching names. The necessary intervention is to use the correctness Duplicate metric to identify the excess records and start a reviewed de-duplication task.

Incorrect Answers

A:

CMDB health checks distinguish missing recommended data from invalid or duplicate CI records. That does not establish correct matching and consolidation of CI identities.

B:

Use suitable CMDB Health inclusion rules to restrict evaluation to classes and records in scope. That does not establish correct matching and consolidation of CI identities.

C:

CI deduplication depends on stable identifiers and relationships, not just visually matching names. The missing change involves using the correctness Duplicate metric to identify the excess records and start a reviewed de-duplication task.

Question 188

For duplicate ci count, the solution has been deployed. Three independent server CIs match an identification rule and represent a single physical server. Which verification best proves it works?

  1. Run jobs in both domains and confirm each tenant's eligible CIs are assessed against its local recommendations.
  2. Inspect cmdb_rel_ci after repair and verify one intended link remains.
  3. Check the duplicate group and confirm one canonical record plus two excess candidates before remediation.
  4. Verify the scorecard's last-calculated timestamp advances and newly ingested CIs are included.

Explanation

Correct Answer

C:

Check the duplicate group and confirm one canonical record plus two excess candidates before remediation. That distinguishes a functioning duplicate ci count path from a configuration that was merely entered.

Incorrect Answers

A:

This inspects an observable outcome of domain-specific quality rules: Run jobs in both domains and confirm each tenant's eligible CIs are assessed against its local recommendations. That check cannot demonstrate correct matching and consolidation of CI identities.

B:

Typed CMDB relationships connect CI endpoints with an explicit supported relationship type and direction. That check cannot demonstrate correct matching and consolidation of CI identities.

D:

This inspects an observable outcome of health job freshness: Verify the scorecard's last-calculated timestamp advances and newly ingested CIs are included. That check cannot demonstrate correct matching and consolidation of CI identities.

Question 189

Three independent server CIs match an identification rule and represent a single physical server. The pilot then reports this problem: A dashboard reports only one duplicate because the team counted the group instead of the extra records. Which explanation best identifies the failed mechanism?

  1. Fixing completeness does not independently eliminate correctness failures.
  2. Domain-separated recommended-field configurations determine which rules apply to each domain.
  3. The metric counts duplicate CIs in a set as the number of matching records minus one.
  4. Dashboard scores represent the most recent completed job, not automatically every new CI update.

Explanation

Correct Answer

C:

The metric counts duplicate CIs in a set as the number of matching records minus one.

Incorrect Answers

A:

CMDB health checks distinguish missing recommended data from invalid or duplicate CI records. The missing change involves the metric counts duplicate CIs in a set as the number of matching records minus one.

B:

Domain-separated recommended-field configurations determine which rules apply to each domain. The different cause concerns the metric counts duplicate CIs in a set as the number of matching records minus one.

D:

Dashboard scores represent the most recent completed job, not automatically every new CI update. The missing change involves the metric counts duplicate CIs in a set as the number of matching records minus one.

Question 190

The initial implementation for duplicate ci count works. Three independent server CIs match an identification rule and represent a single physical server. Which governance measure should sustain it?

  1. Use the dictionary's true required-field policy consistently across ingestion and scheduled health evaluation.
  2. Resolve duplicate tasks with source and relationship review instead of deleting arbitrary sys_ids.
  3. Review inclusion scope with service owners and log intentional exclusions instead of hiding genuine failures.
  4. Maintain auditable templates and rerun audits after significant configuration changes.

Explanation

Correct Answer

B:

Long-term integrity for duplicate ci count depends on Resolve duplicate tasks with source and relationship review instead of deleting arbitrary sys_ids.

Incorrect Answers

A:

Use the dictionary's true required-field policy consistently across ingestion and scheduled health evaluation. That does not establish correct matching and consolidation of CI identities.

C:

Review inclusion scope with service owners and log intentional exclusions instead of hiding genuine failures. That does not establish correct matching and consolidation of CI identities.

D:

Maintain auditable templates and rerun audits after significant configuration changes. That does not establish correct matching and consolidation of CI identities.
