SERVICENOW-CIS-DISCOVERY Practice Test 17 — 15 Questions

Question 1

You need to ensure a specific MID Server only performs WMI scanning. How do you configure this?

Accepted Answer

Update the Capabilities list on the MID Server record. Capabilities are used to restrict or assign specific types of work to a MID Server. Removing other capabilities ensures it only handles WMI tasks.

Answer

Change the MID Server status to 'Validated'

Answer

Modify the Application settings on the MID Server record

Answer

Assign it to a MID Server Cluster

Question 2

What does the 'Heartbeat' indicate in the MID Server record?

Accepted Answer

That the MID server is communicating with the instance. The heartbeat indicates that the instance and the MID server are actively talking to each other.

Answer

That the server is currently scanning

Answer

That the MID server is upgraded

Answer

That the MID server is in a cluster

Question 3

Where are MID Server 'Capabilities' defined?

Accepted Answer

On the MID Server record. Capabilities are defined on the MID Server record under the Capabilities related list.

Answer

In the agent.config file

Answer

In the Discovery Schedule

Answer

In the System Properties

Question 4

Which record type stores the credentials used by Discovery to log into target devices?

Accepted Answer

Credential record. Credentials are stored in the 'Discovery Credentials' table and referenced via Aliases.

Answer

MID Server record

Answer

Discovery Behavior

Answer

Discovery Schedule

Question 5

Which TWO categories are commonly found in the 'Capabilities' list for a MID Server?

Accepted Answer

Discovery. In ServiceNow, a MID Server's Capabilities list determines which jobs the MID Server is allowed to execute, and Discovery (option D) is a core capability because the MID Server performs the horizontal and vertical discovery probes, sensors, and patterns that populate the CMDB. Service Mapping (option E) is likewise a standard MID Server capability, since the MID Server runs the traffic-based and pattern-based mapping probes needed to build service instances and their relationships. Reporting (A) is a platform/UI function performed by users and scheduled jobs, not a MID Server capability, and User Management (B) is handled by the platform's user administration and roles, not by a MID Server. Database Maintenance (C) is not a MID Server capability either; database-level tasks such as table maintenance and cleanup are executed by the instance's database jobs, not by a MID Server.

Answer

Reporting

Answer

User Management

Answer

Database Maintenance

Question 6

You are creating a new Discovery pattern and need to extract data from a command output where lines are separated by a consistent delimiter. Which parsing strategy should you use to map these specific values to table attributes?

Accepted Answer

Delimited parsing. The Delimited parsing strategy is specifically designed for structured text outputs where fields are separated by characters like commas, tabs, or pipes.

Answer

JSON parsing

Answer

XML parsing

Answer

Regex parsing

Question 7

Which action allows you to test a pattern against a specific Discovery status record without running a full Discovery scan?

Accepted Answer

Pattern Designer Test mode. Pattern Designer's Test mode lets you execute a pattern against a specific Discovery status record (a saved Discovery log entry) and step through each step to inspect inputs/outputs, without scheduling or running a full Discovery. This is the standard debugging workflow for pattern development in ServiceNow Discovery. It isolates the pattern logic from the broader Discovery run so you can iterate quickly.

Answer

Modify Discovery Schedule

Answer

Submit a change request

Answer

Re-run Discovery

Question 8

A customer needs to discover devices across a firewall. What is the standard configuration to allow this?

Accepted Answer

Place a MID Server inside the network segment of the target devices.. The standard and recommended approach for discovering devices across a firewall is to place a MID Server inside the target network segment. The MID Server initiates outbound connections to the ServiceNow instance, so only outbound HTTPS (443) needs to be allowed through the firewall — no inbound ports need to be opened to the instance. This is the architecturally correct and secure pattern.

Answer

Open all ports on the firewall.

Answer

Use a VPN connection on the instance.

Answer

Enable 'External Discovery' in the instance.

Question 9

When using the 'Parse Variable' step to extract data, which component is required to capture a specific substring from a larger variable using a capture group?

Accepted Answer

Regular Expression. A Regular Expression is required in the 'Parse Variable' step to capture a specific substring using a capture group. The Parse Variable step supports multiple parsing methods, but only Regular Expression allows you to define a pattern with parentheses (capture groups) to extract a targeted portion of a larger string.

Answer

Delimited Parsing

Answer

XML Path

Answer

JSONPath

Question 10

Which TWO pieces of information can be found in the MID Server record?

Accepted Answer

The host IP address. The MID Server record contains the status and the IP address of the host.

Answer

The full history of all scans

Answer

The user login credentials

Answer

A list of all discovered hardware

Question 11

Which TWO of the following factors contribute to the CMDB Health Dashboard's 'Completeness' score?

Accepted Answer

Presence of required fields.. Completeness is measured by the presence of required and recommended fields on a CI record.

Answer

Number of duplicate CIs.

Answer

Number of relationships to other CIs.

Answer

Time since last discovery.

Question 12

Which of the following parsing strategies is best for a response formatted as a list of key-value pairs separated by equal signs?

Accepted Answer

Name-Value pair parsing. The Name-Value pair parser is specifically designed for such formats.

Answer

Delimiter parsing

Answer

Regex

Answer

JSON parsing

Question 13

Which TWO files or folders are most critical for backing up a MID Server configuration?

Accepted Answer

The keystore folder. The keystore folder (C) is critical because it stores the MID Server's certificates and private keys used for secure authentication and encrypted communication with the ServiceNow instance, so losing it would break the MID Server's trusted connection. The agent.config file (E) is also essential since it holds the MID Server's core configuration parameters — such as instance URL, user credentials, and connection settings — that define how the MID Server operates and connects. The database folder (A) is not part of a MID Server backup because the MID Server does not maintain its own database; data resides on the ServiceNow instance. The temporary file folder (B) only holds transient working files that can be regenerated, and the logs folder (D) contains diagnostic output useful for troubleshooting but not required to restore the MID Server's configuration.

Answer

The database folder

Answer

The temporary file folder

Answer

The logs folder

Question 14

How can you identify which MID Server performed a specific discovery task?

Accepted Answer

Check the Discovery Status record.. The 'Discovery Status' record includes a field showing the MID server that was used for the execution.

Answer

Check the user profile of the sys_admin.

Answer

Check the CMDB CI record.

Answer

Check the ECC Queue output.

Question 15

A discovery scan is failing during the Exploration phase because the credentials are insufficient. Where should you look to find the specific error logs related to this credential failure?

Accepted Answer

The Discovery Log. The Discovery Log is the primary place to find detailed error messages, including credential failures during the Exploration phase. It records each step of the discovery process and any errors encountered.

Answer

The Workflow Context

Answer

The ECC Queue

Answer

The MID Server Issue record
