Question 201.

A Service Mapping administrator notices that an application service contains an unexpected dependency after a recent pattern change. What should be reviewed first?

1. Knowledge article history
   2. Incident assignment rules
   3. Pattern execution results and the relationship logic introduced by the change
   4. Service Catalog approvals

Correct Answer: 3. Pattern execution results and the relationship logic introduced by the change

Explanation:

If an unexpected dependency appears immediately after a pattern change, the modified discovery logic is the most relevant place to investigate. Pattern execution results can show which values, processes, connections, or configuration data caused the relationship to be created. Correcting the source logic prevents the unwanted dependency from being recreated during later discovery runs. Manually removing the relationship alone would address only the symptom.

Question 202.

A Service Mapping job cannot connect to a target because the target subnet is inaccessible from the selected MID Server. What is the best response?

1. Use a MID Server with appropriate network reachability
   2. Create the target CI manually and stop discovery
   3. Disable all credentials
   4. Remove the application service

Correct Answer: 1. Use a MID Server with appropriate network reachability

Explanation:

The MID Server performing discovery must be able to communicate with the target through the required network path and protocol. If the selected MID Server cannot access the subnet, another appropriately placed MID Server may be needed. This is common in segmented networks with firewalls or security zones. Manual CI creation would not solve the underlying inability to discover current attributes and dependencies.

Question 203.

A target is reachable and authentication succeeds, but the discovery account cannot read a required configuration file. What is the most likely issue?

1. DNS failure
   2. Insufficient credential permissions
   3. Incorrect application-service entry point
   4. Duplicate CI identification

Correct Answer: 2. Insufficient credential permissions

Explanation:

If connectivity and authentication are successful but the account cannot read required files, the problem is most likely authorization rather than network access. The discovery account should be given only the additional permissions necessary to perform the required discovery operations. This maintains least privilege while allowing the pattern to retrieve the configuration information it needs.

Question 204.

A mapped service contains several unrelated connections because the application server communicates with many external systems. What should Service Mapping ideally do?

1. Map every observed connection
   2. Remove the application server
   3. Create a separate application service for every connection
   4. Follow only connections relevant to delivering the mapped service**

Correct Answer: 4. Follow only connections relevant to delivering the mapped service

Explanation:

Service Mapping is intended to create meaningful service topology, not a complete representation of every network session on a host. Discovery logic should identify the processes and dependencies relevant to the application service and avoid unrelated connections. This keeps the topology focused, easier to understand, and more useful for impact analysis and troubleshooting.

Question 205.

Why is recurring discovery important after an application is migrated to new infrastructure?

1. It helps update topology to reflect new components and changed dependencies
   2. It guarantees the migration was successful
   3. It eliminates the need for CI identification
   4. It permanently removes all historical data

Correct Answer: 1. It helps update topology to reflect new components and changed dependencies

Explanation:

A migration can change servers, databases, addresses, middleware, cloud resources, and dependency relationships. Recurring discovery helps Service Mapping identify the new architecture and refresh active topology. Without it, the service map may continue to show retired infrastructure or miss new dependencies. Discovery should be complemented by CI lifecycle and relationship-quality management.

Question 206.

A pattern creates duplicate CIs because the same system is discovered under different naming formats. What should be investigated?

1. Incident categorization
   2. CI identification attributes and normalization
   3. Knowledge article approval
   4. Catalog pricing

Correct Answer: 2. CI identification attributes and normalization

Explanation:

Different naming formats can prevent the platform from recognizing that two discovery results represent the same real-world component. Administrators should review the identification attributes being used and whether normalization can make those values consistent. Addressing the identification problem at the source helps prevent repeated duplication and improves the accuracy of service topology.

Question 207.

A Service Mapping administrator wants to confirm how a specific CI relationship was created. Which information is most useful?

1. Service Catalog order history
   2. Employee profile information
   3. Discovery and pattern execution details
   4. Knowledge article ratings

Correct Answer: 3. Discovery and pattern execution details

Explanation:

Discovery and pattern execution information can show what process, connection, configuration file, or command output caused Service Mapping to create a relationship. This makes it possible to validate whether the relationship is legitimate and troubleshoot unexpected topology. Operational information such as catalog orders or employee profiles does not explain the technical basis for a discovered dependency.

Question 208.

An application service relies on a shared database cluster used by six other services. Why should the cluster be mapped to every dependent service?

1. To increase the CI count
   2. To eliminate monitoring
   3. To make discovery faster
   4. To reveal potential cross-service impact if the cluster fails**

Correct Answer: 4. To reveal potential cross-service impact if the cluster fails

Explanation:

Shared infrastructure can become a common point of impact. Mapping the database cluster to each dependent application service allows operations teams to understand the scope of a possible outage or planned maintenance event. This improves incident response, communication, and change planning. Service Mapping provides visibility into shared dependency risk but does not itself prevent failures.

Question 209.

What is the main reason to validate a new service map with an application subject-matter expert?

1. The expert can confirm whether the discovered components and relationships match the real architecture
   2. The expert replaces the MID Server
   3. The expert eliminates the need for patterns
   4. The expert automatically fixes duplicate CIs

Correct Answer: 1. The expert can confirm whether the discovered components and relationships match the real architecture

Explanation:

Technical subject-matter experts often know the expected application tiers, shared services, database connections, and unusual dependencies. Their review provides an important validation layer for automated discovery. Differences between the discovered map and known architecture may reveal missing access, pattern limitations, stale documentation, or unexpected technical dependencies that deserve further investigation.

Question 210.

A standard discovery pattern works on one operating-system version but fails on another supported version because command output differs. What should the administrator consider?

1. Removing the second operating system from the CMDB
   2. Updating the pattern to handle the supported output variation
   3. Disabling discovery for the service
   4. Manually maintaining all affected CIs

Correct Answer: 2. Updating the pattern to handle the supported output variation

Explanation:

Supported environments may produce different command output, file locations, or syntax. Appropriate pattern logic can account for these variations using conditions or alternate parsing. The changes should be tested against representative targets to confirm that they work without affecting other environments. Excluding valid infrastructure would leave the service topology incomplete.

Question 211.

A Service Mapping job works manually but fails during its scheduled execution. Which factors should be compared?

1. Knowledge article formatting
   2. Service Catalog ownership
   3. MID Server selection, credential availability, timing, and execution context
   4. Incident urgency values

Correct Answer: 3. MID Server selection, credential availability, timing, and execution context

Explanation:

Scheduled and manual discovery can run under different conditions. A schedule may select a different MID Server, encounter time-based network restrictions, use different credential context, or run when the target behaves differently. Comparing both executions and reviewing their logs helps isolate the difference. The discovery pattern itself may not be the problem.

Question 212.

A retired server remains on a service map even though the application has moved to a new host. What should be examined?

1. Knowledge Management permissions
   2. Catalog item status
   3. Incident SLAs
   4. CI lifecycle, discovery freshness, and obsolete relationships**

Correct Answer: 4. CI lifecycle, discovery freshness, and obsolete relationships

Explanation:

A retired server appearing as an active service dependency may indicate stale topology, inaccurate lifecycle data, or a discovery process that is not refreshing relationships correctly. Administrators should investigate why the old relationship persists and confirm that the replacement infrastructure is being discovered. Current active topology is important for reliable impact analysis.

Question 213.

Why should discovery credentials follow least-privilege principles?

1. To provide the required discovery access without unnecessary security exposure
   2. To ensure every account has administrator permissions
   3. To eliminate the need for authentication
   4. To prevent CI identification

Correct Answer: 1. To provide the required discovery access without unnecessary security exposure

Explanation:

Discovery accounts need enough access to execute required commands and retrieve configuration data, but additional privileges can increase security risk. Least privilege limits the potential impact of compromised or misused credentials while still supporting Service Mapping. Permissions should be validated periodically as discovery requirements and target environments change.

Question 214.

An application service is distributed across an on-premises environment and two cloud providers. What is the key planning requirement for Service Mapping?

1. Discover only the on-premises systems
   2. Ensure discovery connectivity and credentials cover all relevant environments
   3. Enter all cloud dependencies manually
   4. Use one unrestricted credential for every technology

Correct Answer: 2. Ensure discovery connectivity and credentials cover all relevant environments

Explanation:

A complete service map requires visibility into all relevant components, regardless of where they are hosted. Hybrid and multi-cloud environments may require different network paths, APIs, credentials, or MID Server placements. Planning discovery coverage across every supporting environment helps prevent gaps in the topology and improves cross-environment impact analysis.

Question 215.

A relationship is created between the correct CIs but points in the wrong dependency direction. What should be fixed?

1. The service owner
   2. The target hostname
   3. The relationship creation logic
   4. The MID Server status only

Correct Answer: 3. The relationship creation logic

Explanation:

Relationship direction communicates which component depends on or supports another. If it is reversed, incident and change impact analysis can become misleading. The discovery or pattern logic that creates the relationship should be corrected so future runs consistently produce the right direction. Manual correction is not sustainable if discovery continues recreating the error.

Question 216.

Why is recurring Service Mapping discovery especially valuable for cloud-native services?

1. Cloud resources are always static
   2. Cloud services never require credentials
   3. Cloud topology cannot change automatically
   4. Resources may scale, move, appear, and disappear frequently**

Correct Answer: 4. Resources may scale, move, appear, and disappear frequently

Explanation:

Cloud-native environments can change rapidly as instances, containers, databases, and other resources are replaced or scaled automatically. Recurring discovery helps keep the application topology synchronized with these changes. A map created only once may quickly become stale and provide inaccurate impact information. Discovery frequency should reflect the rate of change in the environment.

Question 217.

A pattern modification works correctly on a test system. What should be done before broad production deployment?

1. Test it against a representative set of production-like targets
   2. Assume all production systems are identical
   3. Disable logging
   4. Remove CI identification rules

Correct Answer: 1. Test it against a representative set of production-like targets

Explanation:

One successful test does not guarantee that the pattern will behave correctly across different operating systems, application versions, configuration layouts, and security settings. Representative testing helps reveal environmental differences before the pattern affects many systems. Reviewing resulting CIs and relationships also protects CMDB and Service Mapping quality.

Question 218.

A mapped server has many active connections, but only one database connection is relevant to the application service. What should the topology include?

1. Every network connection on the server
   2. The relevant database dependency and other service-related relationships
   3. No connections at all
   4. Only manually created relationships

Correct Answer: 2. The relevant database dependency and other service-related relationships

Explanation:

Service Mapping should represent the technical dependencies needed to understand how the application service is delivered. Including every network connection can create unnecessary noise and obscure the important dependency chain. Discovery logic should focus on the application’s actual processes, configurations, and connections so the resulting topology remains meaningful.

Question 219.

A discovery account can connect to the target but receives “permission denied” when executing a required command. What does this most strongly indicate?

1. DNS failure
   2. MID Server network failure
   3. Insufficient account privileges
   4. Duplicate CI identification

Correct Answer: 3. Insufficient account privileges

Explanation:

If a session can be established successfully, basic network connectivity and authentication are working. A permission-denied response during command execution indicates that the account lacks the authorization required for that operation. Administrators should adjust permissions only as necessary, maintaining least privilege while ensuring the pattern can collect the required information.

Question 220.

Which operating practice best supports trustworthy Service Mapping at enterprise scale?

1. Perform discovery once and never refresh the maps
   2. Maintain all dependencies manually
   3. Ignore duplicate CIs until an outage occurs
   4. Continuously monitor discovery health, CMDB quality, credentials, pattern behavior, and topology freshness**

Correct Answer: 4. Continuously monitor discovery health, CMDB quality, credentials, pattern behavior, and topology freshness

Explanation:

Enterprise Service Mapping requires ongoing operational management. Infrastructure changes, credentials expire, duplicate CIs appear, network rules change, and pattern behavior can regress over time. Monitoring these areas continuously helps teams identify problems before the topology becomes unreliable. Accurate, current service maps depend on both good initial design and disciplined long-term maintenance.
