SERVICENOW-CIS-DISCOVERY Practice Test 4 — 25 Questions

Question 1

How does Discovery handle the identification of a device that has had its IP address changed since the last discovery?

Accepted Answer

It uses Identification Rules to match the device based on hardware attributes.. Discovery uses Identification rules based on unique hardware attributes (like serial numbers) to reconcile the CI, regardless of IP changes.

Answer

It deletes the old CI and creates a new one.

Answer

It requires a manual merge in the CI list.

Answer

It fails because the IP address does not match.

Question 2

What does the 'Debug' mode in the Pattern Designer require to function?

Accepted Answer

A selected Discovery status record (node).. Debug mode requires a target node to execute the pattern against, which is provided by a Discovery status record.

Answer

A new CI class.

Answer

A valid user session.

Answer

The MID Server to be in debug mode.

Question 3

You are modifying a pattern and need to extract a specific attribute from a JSON response returned by an API. Which step type is most appropriate for this task?

Accepted Answer

Parse JSON. The Parse JSON step type is purpose-built to parse a JSON payload and extract specific attributes by navigating the JSON structure using JSONPath or dot notation. When a pattern receives an API response in JSON format, Parse JSON lets you map individual fields (e.g., $.data.id) into variables that subsequent steps can use. This is the correct and most efficient way to pull a specific attribute from a JSON response.

Answer

Parse Variable

Answer

Set Parameter

Answer

Regex Extract

Question 4

You have multiple MID Servers in a cluster. Where do you define the capability that restricts a specific MID Server to only perform 'Windows' discovery?

Accepted Answer

MID Server record. MID Server Capabilities are used to filter which MID Servers handle specific types of discovery tasks.

Answer

Discovery Schedule

Answer

Discovery Behavior

Answer

Credential Alias

Question 5

Which of the following is the most effective way to view the relationships of a CI in a graphical format?

Accepted Answer

Dependency View. The Dependency View is the standard graphical interface for viewing CI relationships in ServiceNow.

Answer

CMDB Health Dashboard

Answer

List View

Answer

Discovery Status

Question 6

A customer needs to restrict a MID Server to only perform discovery on specific IP ranges. Which mechanism should be used to accomplish this?

Accepted Answer

Define 'MID Server IP Ranges' related list on the MID Server record.. MID Server IP Ranges are used to define the boundaries of what a specific MID Server is allowed to scan.

Answer

Set the 'Scan Limitation' property on the MID Server configuration file.

Answer

Use the 'Discovery Schedule' Exclude IP list only.

Answer

Apply a Business Rule to the ECC Queue.

Question 7

How do you associate a specific MID Server with a Discovery Schedule?

Accepted Answer

By selecting it in the 'MID Server' field on the Discovery Schedule.. The MID Server is selected on the Discovery Schedule record directly.

Answer

Through a Discovery Behavior.

Answer

Via a credential alias.

Answer

By modifying the IP Range.

Question 8

During a Discovery run, a Linux server is identified, but the CMDB record is not updated with the latest memory information. Which log should be inspected to troubleshoot the Identification and Reconciliation engine (IRE) process?

Accepted Answer

System Logs > Identification and Reconciliation Engine Logs. The Identification and Reconciliation Engine (IRE) processes discovery data to identify CIs and reconcile them into the CMDB. When IRE fails to update CI attributes such as memory information, the IRE log is the correct place to inspect for identification errors, reconciliation rule mismatches, or payload issues. This log is accessed via System Logs > Identification and Reconciliation Engine Logs.

Answer

System Logs > Node Logs

Answer

Discovery > Pattern Logs

Answer

System Logs > Discovery Logs

Question 9

Which TWO of the following are valid ways to define the scope of a Discovery scan?

Accepted Answer

IP Address ranges. A Discovery scan scope can be defined by specifying one or more IP address ranges (for example, 10.0.0.1-10.0.0.254) that Discovery will probe for live devices. Option C (IP Network addresses) is also correct because scope can be defined using IP network/subnet addresses in CIDR notation (for example, 192.168.1.0/24), which Discovery uses to determine which hosts to scan. Schedule Behaviors (B) control when and how often a Discovery schedule runs, not which devices are in scope. MID Server Capability (D) determines which MID Server is eligible to execute the Discovery based on its assigned capabilities, but it does not define the target scope. Credential profiles (E) supply the authentication credentials used during Discovery, not the set of IP addresses or networks to be scanned.

Answer

Schedule Behaviors

Answer

MID Server Capability

Answer

Credential profiles

Question 10

Which of the following describes the purpose of the 'CI Class Manager'?

Accepted Answer

To manage class hierarchy and CI rules.. It provides a centralized interface for managing the configuration of all CI classes, including identification and reconciliation rules.

Answer

To manage user roles.

Answer

To perform network vulnerability scans.

Answer

To schedule Discovery jobs.

Question 11

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 12

When a pattern step executes an external script (e.g., Python), how can you ensure the pattern waits for the script to finish before proceeding to the next step?

Accepted Answer

The pattern automatically waits for the step process to return. ServiceNow patterns are synchronous by default; the pattern engine waits for each step to return a status (Success/Failure) before moving to the next step.

Answer

Use an asynchronous flag in the script

Answer

Configure the MID Server to process sequentially

Answer

Add a Wait step

Question 13

A MID Server Cluster is configured with two nodes. One node goes down. How does the MID Server Cluster handle the failover?

Accepted Answer

The cluster automatically shifts the workload to the healthy node in the cluster.. MID Server clusters automatically distribute work, and if one node fails, the cluster manager ensures tasks are re-queued or picked up by the remaining node.

Answer

The cluster requires a manual restart of the remaining node to resume work.

Answer

The instance marks the MID Server as 'Down' and stops all processing for the entire cluster.

Answer

All tasks are automatically lost and must be manually re-run.

Question 14

Which THREE of the following are necessary to successfully discover a Windows server?

Accepted Answer

Network connectivity to the server. You need a reachable network, a credential with access, and a valid classifier for Windows.

Answer

An active Incident Management module

Answer

A manual CI creation

Question 15

Which TWO of the following are valid parsing strategies available in the Pattern Designer when processing data retrieved from a device?

Accepted Answer

JSON. The Pattern Designer supports various parsers including 'Delimited' (for tables) and 'JSON' (for object data).

Answer

SQL Query

Answer

SOAP Envelope

Answer

Binary Stream

Question 16

You are deploying a MID Server behind a strict firewall. To ensure the MID Server can communicate with the ServiceNow instance without opening unsolicited inbound ports, which configuration is required?

Accepted Answer

Ensure the firewall allows outbound HTTPS traffic from the MID Server to the instance.. MID Servers communicate via outbound HTTPS (443) requests to the instance, meaning no inbound ports need to be opened on the firewall.

Answer

Set the MID Server listener port to 8443 on the local firewall.

Answer

Configure the instance to use an inbound static IP for the MID Server.

Answer

Enable the 'Inbound Proxy' setting in the MID Server configuration file.

Question 17

What is the primary role of the Identification and Reconciliation Engine (IRE) in the Discovery process?

Accepted Answer

To ensure data integrity and prevent CI duplication.. The IRE acts as a gatekeeper to ensure that only valid, non-duplicate, and authorized data is written to the CMDB.

Answer

To execute discovery probes on target devices.

Answer

To monitor the status of MID servers.

Answer

To map business services based on traffic data.

Question 18

When a MID Server is part of a cluster, what happens to the ECC queue items if one MID Server goes down?

Accepted Answer

The ECC queue items are re-assigned to other MID Servers in the cluster. If load balancing is configured, the other nodes in the cluster take over the work.

Answer

The ECC queue items are deleted

Answer

The jobs are marked as 'Failed'

Answer

The jobs stay in the queue until the failed server returns

Question 19

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 20

What is the purpose of the 'Table' attribute in the 'Identification' step?

Accepted Answer

To specify the target CMDB class.. The 'Table' attribute defines which CMDB class the identified CI belongs to.

Answer

To set the CI relationship type.

Answer

To filter the input data.

Answer

To name the variable.
