SERVICENOW-CIS-DISCOVERY Practice Test 12 — 15 Questions

Question 1

If you have a pattern that identifies a CI but fails to update its attribute, which log should you check first?

Accepted Answer

Discovery Pattern Log. The Discovery Pattern Log provides the most detail regarding step execution and attribute assignment failures.

Answer

System Log

Answer

CMDB Health Dashboard

Answer

MID Server Log

Answer

Node Log

Question 2

When reviewing the CMDB Health Dashboard, you notice a high 'Staleness' score for several Windows servers. What is the primary cause of high staleness?

Accepted Answer

The CIs have not been updated by Discovery within the configured staleness threshold.. The Staleness score in the CMDB Health Dashboard measures how long it has been since a CI was last updated by Discovery or another authoritative source. A high staleness score means the CI's 'last discovered' or 'updated' timestamp exceeds the configured staleness threshold, indicating the CI data is outdated. This is the direct definition of staleness in ServiceNow CMDB Health.

Answer

The CIs are not being reconciled correctly.

Answer

The Discovery credentials failed during the last scan.

Answer

The CIs have invalid relationship types.

Question 3

What is the primary benefit of using a MID Server?

Accepted Answer

It allows discovery behind firewalls. MID Servers allow for secure, firewalled data collection without exposing the instance directly to the internal network.

Answer

It replaces the need for a database

Answer

It increases the number of users

Answer

It makes discovery faster

Question 4

Which TWO actions should you perform if a MID Server is not showing 'Up' in the instance?

Accepted Answer

Verify the MID Server service is running on the host. Checking the service status on the host and the ECC Queue for connectivity errors are the two initial troubleshooting steps.

Answer

Change the proxy server settings

Answer

Create a new discovery schedule

Answer

Update the MID Server version

Question 5

What happens to the MID Server service if the host machine reboots?

Accepted Answer

It will start automatically if configured as a system service. If the MID Server is configured as a system service (e.g., Windows Service or Linux daemon), it will automatically start when the host machine reboots. This is the recommended configuration for production environments to ensure continuous discovery and integration. The MID Server service is designed to be resilient and restart automatically if set up correctly.

Answer

It will stay down until manually started

Answer

It will be uninstalled

Answer

It will require a re-validation

Question 6

Which THREE types of metrics are tracked by the CMDB Health Dashboard?

Accepted Answer

Compliance. The CMDB Health Dashboard tracks metrics across three categories: Completeness, Correctness, and Compliance.

Answer

Performance

Answer

Scalability

Question 7

What is the primary function of the Discovery 'Exploration' phase?

Accepted Answer

To run patterns and gather detailed attributes.. Exploration executes patterns to collect detailed configuration data from the device.

Answer

To classify the device.

Answer

To identify open ports.

Answer

To reconcile CIs.

Question 8

If you are troubleshooting a Discovery issue where the device is correctly classified but no data is being populated in the CMDB, which phase should you investigate first?

Accepted Answer

Exploration. If a device is correctly classified but no data is populated in the CMDB, the Exploration phase should be investigated first. Exploration is responsible for gathering detailed information from the device, such as hardware, software, and network configuration. If Exploration fails or is misconfigured, no data will be collected, even if classification and identification succeed.

Answer

Shazzam

Answer

Schedule

Answer

Classification

Answer

Identification

Question 9

Which TWO of the following are key components of the Pattern Designer?

Accepted Answer

Debug panel. The designer consists of the step palette and the execution/debug environment.

Answer

Update Set Manager

Answer

CMDB Health dashboard

Answer

CI Class Manager

Question 10

Which THREE of the following items are stored in the Credential record?

Accepted Answer

Password. Credential records typically store Usernames, Passwords, and SSH keys/certificates.

Answer

IP Address

Answer

MAC Address

Question 11

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 is the central place to review the outcome of a Discovery run for a specific device. It contains the Discovery Log, which shows each phase (scanning, classification, identification, exploration, and probes/sensors) and any errors or warnings encountered. Opening the Discovery Status record for the relevant schedule/device gives you the detailed log needed to troubleshoot why a device was or wasn't discovered correctly.

Answer

In the CMDB CI record.

Answer

In the MID Server dashboard.

Answer

In the System Log.

Question 12

When troubleshooting a specific device, how can you see exactly what was returned by the probes?

Accepted Answer

View the ECC Queue records related to the status.. The Discovery Status record allows you to drill down into the 'Devices' and 'ECC Queue' to see the raw input data.

Answer

Run the discovery again.

Answer

Check the MID Server logs.

Answer

View the CI record.

Question 13

A discovery administrator notices that a Windows server is discovered and classified correctly, but its serial number and manufacturer fields remain empty in the CMDB. The MID Server is up, the credentials are validated, and other Windows servers on the same schedule populate these fields. Which configuration should the administrator review first?

Accepted Answer

The Windows OS pattern's WMI probe steps that query hardware inventory.. On Windows, hardware attributes such as serial number and manufacturer come from WMI queries performed by pattern probes. When one server is missing those values while its peers are complete, the likely cause is a failing or excluded probe step for that device, such as a WMI access issue or a step condition that did not match. Reviewing the pattern's WMI probe steps and their results pinpoints the problem.

Answer

The schedule's MID Server selection criteria.

Answer

The Discovery Schedule's 'Max Run Time' value.

Answer

The CI Class Manager entry for the Windows Server class.

Question 14

You are creating a custom CI class. Which step is essential to ensure that Discovery can identify CIs of this new class?

Accepted Answer

Define an Identification Rule for the new class.. You must create an Identification Rule for the new class, otherwise the system won't know how to handle incoming discovery data for it.

Answer

Add the class to the global discovery schedule.

Answer

Assign a default MID server.

Answer

Publish the class to the Service Catalog.

Question 15

You notice a MID Server has the status 'Down' in the ServiceNow instance, but the service is running on the host. What is the first step to troubleshoot?

Accepted Answer

Check the agent log file (agent/logs/agent0.log.0) for connection errors.. Checking the agent log is the standard first step for identifying why the MID Server is failing to heartbeat or authenticate.

Answer

Restart the ServiceNow instance.

Answer

Update the MID Server version in the MID Server record.

Answer

Reinstall the MID Server.
