Question 321

Which Discovery stage determines the type of device responding to the initial scan?

1. Identification
2. Reconciliation
3. Classification
4. Processing

Correct Answer: 3

Explanation

Classification determines the type of device or system that has responded to the initial Discovery activity. This information helps Discovery determine which subsequent collection methods are appropriate for the target. Different technologies may require different protocols, credentials, patterns, probes, or other mechanisms for detailed information gathering. Identification has a different purpose because it determines whether the discovered information matches an existing CI. Reconciliation manages authority between data sources, while processing handles collected information. When a target is classified incorrectly, administrators should investigate the classification evidence and related Discovery configuration before troubleshooting later exploration or identification stages.

Question 322

What should an administrator review if a Discovery Schedule repeatedly runs against an unintended IP range?

1. Credential Affinity
2. The schedule’s configured IP range and associated scope
3. Pattern debugging
4. CMDB reconciliation

Correct Answer: 2

Explanation

If a Discovery Schedule repeatedly scans an unintended IP range, the administrator should review the schedule’s configured scope and IP range. Discovery scope determines which addresses are eligible for scanning, so an incorrectly configured range can cause unintended systems to be included. Administrators should also review exclusions and related Discovery configuration when necessary. Credential Affinity controls credential selection, Pattern debugging helps investigate pattern execution, and CMDB reconciliation governs data-source authority. None of those directly defines the scheduled scanning range. Keeping Discovery scope accurate helps control network traffic, execution time, and the systems included in CMDB management.

Question 323

Which credential type is commonly associated with discovering network devices using SNMP?

1. SNMP credentials
2. WMI credentials
3. SSH credentials only
4. Database credentials

Correct Answer: 1

Explanation

SNMP credentials are commonly used when Discovery collects information from supported network devices through the Simple Network Management Protocol. Depending on the environment and SNMP configuration, the required authentication or community information must be correctly configured and accessible to the Discovery process. WMI is generally associated with Windows infrastructure, while SSH is commonly used for Linux and UNIX systems. Database credentials serve database-specific authentication requirements. When network-device Discovery fails, administrators should review the SNMP configuration, target accessibility, firewall rules, selected MID Server, and device-side SNMP settings.

Question 324

What is a primary function of a MID Server in Discovery?

1. To permanently store all CMDB data
2. To create user accounts
3. To replace identification rules
4. To execute Discovery operations against accessible target infrastructure

Correct Answer: 4

Explanation

The MID Server provides an execution point through which Discovery can communicate with target infrastructure. It can perform operations against systems that may not be directly accessible from the ServiceNow instance and can return collected information for further processing. A MID Server does not permanently store all CMDB information, create user accounts, or replace identification rules. In enterprise environments, administrators may deploy multiple MID Servers to address network segmentation, workload distribution, availability, and specialized access requirements. When troubleshooting Discovery, it is important to distinguish between communication from the MID Server to the instance and communication from the MID Server to target infrastructure.

Question 325

Which condition can cause Discovery to create a duplicate CI instead of updating an existing one?

1. Incorrect or insufficient identifying information
2. A successful ping response
3. An active Discovery Schedule
4. A healthy MID Server

Correct Answer: 1

Explanation

Incorrect or insufficient identifying information can prevent Discovery from matching a target with an existing CI. When identification rules cannot find a reliable match, Discovery may create another CI even though the system already exists in the CMDB. Administrators investigating duplicates should review the identifying attributes collected from the target and the applicable identification rules. A successful ping, an active Discovery Schedule, and a healthy MID Server are useful operational conditions but do not guarantee correct CI matching. Accurate identification is essential for maintaining CMDB quality and avoiding duplicate records that can affect reporting and infrastructure relationships.

Question 326

A pattern step executes successfully but returns an empty variable. What should the administrator investigate?

1. User notification settings
2. Pattern variable assignment and parsing logic
3. Service Catalog approvals
4. Knowledge article permissions

Correct Answer: 2

Explanation

If a pattern step executes but produces an empty variable, the administrator should investigate the variable assignment and parsing logic. The target command may have returned information, but the pattern may not have extracted or assigned the expected value correctly. Pattern debugging can help reveal the actual output and show how the value is processed between steps. User notification settings, Service Catalog approvals, and Knowledge article permissions do not normally affect pattern variables. Administrators should also consider whether the target returned a different format or whether permissions caused the expected information to be unavailable. Reviewing the specific failing step is more effective than changing unrelated configuration.

Question 327

Why should Discovery schedules be planned carefully in large environments?

1. To eliminate the need for identification
2. To increase the number of duplicate CIs
3. To manage network, MID Server, and target-system workload
4. To disable all Discovery credentials

Correct Answer: 3

Explanation

Discovery schedules should be planned carefully in large environments because scanning can consume network bandwidth, MID Server processing capacity, and resources on target systems. Running many large Discovery operations simultaneously may create unnecessary contention and increase execution times. Administrators can manage this by defining appropriate scopes, staggering schedules, distributing workloads, and monitoring performance. Scheduling does not eliminate identification requirements or disable credentials. It should also not be designed to increase duplicate CIs. Effective scheduling balances the need for current infrastructure information with the operational capacity of the environment.

Question 328

What should be checked when a MID Server is online but Discovery jobs are not being assigned to it?

1. Knowledge Base permissions
2. User language settings
3. Service Catalog categories
4. MID Server capabilities and Discovery selection criteria

Correct Answer: 4

Explanation

A MID Server can be online and still not be eligible for a particular Discovery operation. Administrators should review its capabilities, Discovery Behavior, network access, and other selection criteria that determine whether it can execute the required work. An online status primarily indicates that the MID Server is communicating with the instance; it does not guarantee eligibility for every Discovery task. Knowledge permissions, user language settings, and Service Catalog categories are unrelated to MID Server selection. When an expected MID Server is not being used, comparing its configuration with a MID Server that successfully executes similar jobs can help identify the difference.

Question 329

Which approach is useful when troubleshooting a Discovery failure that occurs only on one target?

1. Compare the target’s configuration, permissions, credentials, and network access with a successful target
2. Delete all Discovery schedules
3. Remove all CMDB records
4. Disable all firewalls

Correct Answer: 1

Explanation

When Discovery fails only on one target, comparing that target with a successfully discovered system is an effective troubleshooting approach. Differences may exist in credentials, permissions, firewall rules, installed services, operating-system configuration, command output, or network access. Administrators should identify the exact Discovery stage where the failure occurs and then compare relevant configuration details. Deleting schedules, removing CMDB records, or disabling all firewalls does not provide a controlled troubleshooting method. A targeted comparison helps isolate environmental differences while minimizing unnecessary changes to the broader Discovery architecture.

Question 330

What is the purpose of Discovery credentials?

1. To define IP ranges
2. To authenticate to target systems and access required information
3. To determine CI identification rules
4. To schedule Discovery jobs

Correct Answer: 2

Explanation

Discovery credentials are used to authenticate to target systems so that the Discovery process can access information that requires authorization. Different technologies may require different credential types, and the selected account must have appropriate permissions for the required operations. Credentials do not define IP ranges, schedule Discovery jobs, or determine CI identification rules. When authentication-dependent information is missing, administrators should review credential validity, permissions, protocol availability, and target-side configuration. Maintaining valid and appropriately privileged credentials is essential for reliable Discovery, particularly in environments where passwords or access policies change regularly.

Question 331

Which feature helps identify the existing CI that corresponds to discovered information?

1. Discovery Schedule
2. MID Server Capability
3. Identification rules
4. Discovery Exclusion

Correct Answer: 3

Explanation

Identification rules help Discovery determine which existing CI corresponds to the information collected from a target. They evaluate identifying information to determine whether the discovered system matches an existing CMDB record or should be represented as a new CI. Discovery Schedules control when scanning occurs, MID Server capabilities influence execution eligibility, and Discovery Exclusions control which systems should not be scanned. When duplicate CIs appear, administrators should review the identification process and the identifying attributes being collected. Reliable identification is essential for maintaining accurate CMDB records and preventing unnecessary duplication.

Question 332

A server is correctly classified, but software information is missing. What should be investigated?

1. Discovery Schedule name
2. User interface theme
3. Knowledge article ownership
4. The collection mechanism, credentials, permissions, and applicable Discovery content

Correct Answer: 4

Explanation

Correct classification only confirms that Discovery has identified the general type of target. Software information may still require additional collection mechanisms, permissions, credentials, commands, or Discovery content. Administrators should investigate the relevant pattern or collection logic and verify that the target account can access the required information. Logs and debugging tools can help identify where the software information collection fails. The schedule name, user interface theme, and Knowledge article ownership do not normally control software collection from infrastructure systems. Troubleshooting should focus on the specific attribute that is missing and the Discovery stage responsible for collecting and processing it.

Question 333

Which configuration can help direct Discovery work toward a MID Server with the required network access?

1. Discovery Behavior
2. Knowledge Management
3. User Criteria
4. Service Catalog configuration

Correct Answer: 1

Explanation

Discovery Behavior can help determine how Discovery work is executed and which MID Server is appropriate for a particular operation. This is particularly useful in environments containing multiple MID Servers with different network access or capabilities. Administrators should configure Discovery Behavior consistently with the organization’s network architecture and execution requirements. Knowledge Management, User Criteria, and Service Catalog configuration serve other platform functions and do not normally determine Discovery execution routing. When a Discovery job is consistently assigned to an unsuitable MID Server, reviewing Discovery Behavior together with MID Server capabilities and network access can help resolve the issue.

Question 334

Why should Discovery exclusions be reviewed after major network changes?

1. They determine Knowledge article permissions
2. Network changes can make previously excluded or included addresses no longer appropriate
3. They automatically update all credentials
4. They replace CMDB reconciliation

Correct Answer: 2

Explanation

Network changes can alter which systems should or should not be included in Discovery. New subnets, address changes, decommissioned systems, and security-zone changes may make existing exclusions outdated. Administrators should therefore review Discovery exclusions and ranges after significant infrastructure changes to ensure that the intended scope remains accurate. Exclusions do not manage Knowledge permissions, automatically update credentials, or replace CMDB reconciliation. Regular scope review reduces the risk of scanning systems outside the intended boundary and helps ensure that newly added infrastructure is included when appropriate.

Question 335

What does successful target classification followed by failed exploration usually indicate?

1. The target cannot respond to any network request
2. The CMDB has been deleted
3. A later collection, authentication, permission, or protocol issue may exist
4. The Discovery Schedule is necessarily invalid

Correct Answer: 3

Explanation

If classification succeeds but exploration fails, the target has already provided enough information for Discovery to determine its general type. The problem is therefore more likely to occur during a later collection stage. Administrators should investigate credentials, permissions, required protocols, target-side services, firewall rules, and the relevant Discovery content. A classification result demonstrates that some communication was successful, but it does not guarantee that deeper information can be collected. The CMDB does not need to be deleted, and the Discovery Schedule is not necessarily invalid. Focusing on the exploration stage provides a more targeted troubleshooting path.

Question 336

Which activity is most appropriate for monitoring whether scheduled Discovery operations are succeeding or failing?

1. Discovery status and related execution information
2. Knowledge article reports
3. Service Catalog dashboards
4. User profile settings

Correct Answer: 1

Explanation

Discovery status and related execution information provide useful visibility into whether scheduled Discovery operations are succeeding or failing. Administrators can use this information to identify unsuccessful targets, incomplete runs, credential problems, communication issues, or other Discovery-related conditions. Knowledge article reports, Service Catalog dashboards, and user profile settings are not the primary tools for monitoring infrastructure Discovery. Regular monitoring is important in large environments because a schedule may continue running even when individual targets or network segments repeatedly fail. Reviewing status information together with logs and MID Server health provides a stronger basis for troubleshooting recurring Discovery problems.

Question 337

A Discovery account can authenticate successfully but cannot retrieve certain protected attributes. What is the most likely issue?

1. The Discovery Schedule is missing
2. The IP range is too large
3. The account may lack required permissions for those attributes
4. The MID Server must be deleted

Correct Answer: 3

Explanation

Successful authentication does not mean that the account has permission to access every piece of system information. If only protected attributes are missing, administrators should investigate whether the Discovery account has the required privileges for those specific operations. The appropriate solution is to identify the missing permission and grant only the necessary access according to least-privilege principles. A missing schedule or large IP range would not normally explain why only protected attributes are unavailable. Deleting the MID Server is also unnecessary. Target permissions and the Discovery mechanism responsible for collecting the missing information should be reviewed carefully.

Question 338

What should an administrator consider when a Discovery Pattern depends on a command available only on some target systems?

1. User notification settings
2. Target compatibility and alternate collection logic
3. Knowledge article formatting
4. Service Catalog approvals

Correct Answer: 2

Explanation

If a Discovery Pattern depends on a command that is not available on every target, administrators should consider target compatibility and whether alternate collection logic is required. Operating-system versions, installed utilities, security policies, and system configuration can affect command availability and output. Pattern debugging can help identify the point at which execution fails. Administrators should avoid assuming that systems with the same general operating system will always return identical command behavior. User notifications, Knowledge formatting, and Service Catalog approvals do not resolve target command compatibility. Robust Discovery content should account for supported variations where appropriate.

Question 339

Which condition can increase the likelihood of inaccurate CMDB relationships after Discovery?

1. Accurate target credentials
2. Proper MID Server placement
3. Correct Discovery scope
4. Incorrect or incomplete information about discovered CIs and their relationships

Correct Answer: 4

Explanation

Inaccurate or incomplete information about discovered CIs can lead to inaccurate CMDB relationships. Relationships depend on Discovery being able to correctly identify infrastructure components and collect the information needed to establish their connections. Problems with identification, permissions, collection logic, or target-specific configuration can therefore affect relationship accuracy. Proper credentials, appropriate MID Server placement, and correct Discovery scope generally support more reliable results rather than causing relationship problems. When relationships appear incorrect, administrators should examine the underlying CI identification, collected attributes, Discovery content, and target information rather than focusing only on the relationship record itself.

Question 340

Which overall approach supports maintainable Discovery in a large enterprise?

1. Scan every possible address continuously
2. Use unrestricted credentials
3. Disable network security controls
4. Combine controlled scope, suitable MID Servers, valid credentials, monitoring, and accurate CMDB identification

Correct Answer: 4

Explanation

A maintainable enterprise Discovery implementation combines controlled scope, suitable MID Servers, valid credentials, monitoring, and accurate CMDB identification. Controlled scope prevents unnecessary scanning, while appropriate MID Servers provide network access and workload distribution. Valid credentials allow required information to be collected, and monitoring helps administrators detect failures or incomplete results. Accurate identification helps ensure that discovered systems are matched correctly to CMDB records. Continuously scanning every possible address, using unrestricted credentials, or disabling network security controls can introduce operational and security problems. A structured approach provides infrastructure visibility while maintaining appropriate boundaries and supporting long-term CMDB data quality.
