SERVICENOW-CIS-DISCOVERY Practice Test 18 — 15 Questions

Question 1

Which THREE of the following are valid ways to handle command output in a pattern?

Accepted Answer

Parse it with regex. Option A is correct because regex parsing is a standard mechanism for extracting structured values from raw command output within a pattern, allowing specific fields to be captured for later use. Option B is correct because command output can be evaluated in a condition (e.g., checking for a specific string or exit status) to control the pattern's execution flow. Option E is correct because assigning the output to a variable lets subsequent pattern steps reference and reuse that data, which is a core capability of pattern-based orchestration. Option C is not a valid handling method since deleting output from the MID Server is not a pattern operation and the MID Server does not store command output in that manner. Option D is not a pattern-level handling mechanism; emailing output to an admin is an external notification action, not a way to process command output inside a pattern.

Answer

Delete it from the MID Server

Answer

Email it to the admin

Question 2

Which TWO of the following are true regarding MID Server startup parameters in the config.xml?

Accepted Answer

They contain the instance URL and the MID server user credentials.. Option B is correct because config.xml stores the essential connection parameters the MID Server needs, including the instance URL (e.g., https://<instance>.service-now.com) and the MID Server user credentials used to authenticate to the instance. Option D is correct because these startup parameters are precisely what the MID Server reads on initial startup to establish its connection and register with the instance before any instance-side properties can be applied. Option A is incorrect because config.xml is a local file on the MID Server host and is not editable through the ServiceNow UI. Option C is incorrect because instance-side MID Server record properties take precedence over the local config.xml values once the MID Server is connected, not the other way around. Option E is incorrect because config.xml is not automatically synced with instance properties on an hourly schedule; it is a local bootstrap configuration file.

Answer

The file can be edited via the ServiceNow UI.

Answer

These settings override any properties set in the MID Server record in the instance.

Answer

They are automatically synced with the instance properties every hour.

Question 3

Which module allows you to visualize the dependencies and connections between CIs in a map view?

Accepted Answer

Dependency View. The Dependency View is the standard ServiceNow interface for visualizing CI relationships.

Answer

CMDB Query Builder

Answer

Discovery Status

Answer

Business Service Map

Question 4

During pattern debugging, you notice that a specific step is failing to run on a MID Server. You want to see the exact input and output of that step. Where should you look?

Accepted Answer

Pattern Designer Debugger. The Debugging mode in Pattern Designer provides an 'Input/Output' tab that captures the raw data for every step executed.

Answer

Discovery Log

Answer

ECC Queue

Answer

MID Server Agent Log

Question 5

If a pattern step fails due to a timeout, where should you investigate the specific output of the command that was executed just before the failure occurred?

Accepted Answer

Pattern Debugger Output. The 'Debug' session output in the Pattern Designer records the output of every step, including those immediately preceding a failure.

Answer

Discovery Status record

Answer

MID Server Log

Answer

Discovery Dashboard

Question 6

Which type of credential is primarily used by Discovery patterns to execute commands on a Linux-based target via SSH?

Accepted Answer

SSH Credentials. SSH Credentials are the credential type used by Discovery patterns to authenticate and execute commands on Linux-based targets over SSH (port 22). ServiceNow stores SSH credentials (username, password, or private key) in the Credentials table and associates them with the appropriate Discovery schedule or MID server. When a pattern runs against a Linux host, it retrieves the SSH credential to establish the SSH session and run commands like 'uname -a' or 'cat /etc/os-release'.

Answer

API Key

Answer

SNMP Community String

Answer

Windows Credentials

Question 7

Which of the following is NOT a required part of a Discovery Schedule?

Accepted Answer

Excluded IP Range.. A Discovery Schedule requires a Target IP Range, a MID Server, and a Discovery Behavior to define what to discover and how. An Excluded IP Range is optional; it is used to exclude specific IPs from the target range but is not mandatory for the schedule to run. Therefore, Excluded IP Range is NOT a required part.

Answer

Target IP Range.

Answer

MID Server.

Answer

Discovery Behavior.

Question 8

What is the purpose of an 'IP Service' in Discovery?

Accepted Answer

To define a set of ports and protocols for scanning.. IP Services group ports and protocols together for use in port scanning, making it easier to define what to scan.

Answer

To assign a MID Server.

Answer

To define the IP range.

Answer

To provide credentials.

Question 9

Which of the following would be the best reason to create a custom Discovery Behavior?

Accepted Answer

To control which probes are run for a specific type of device.. A custom Discovery Behavior is created to control which probes are run for a specific type of device. This allows you to tailor the discovery process to different device classes, ensuring that only relevant probes are executed. This is the primary reason to create a custom behavior, as it provides flexibility in discovery execution.

Answer

To define the IP range for a subnet.

Answer

To manage MID Server credentials.

Answer

To schedule discovery at a different time.

Question 10

Which TWO ways can you view MID Server logs?

Accepted Answer

Directly on the MID Server host file system. You can view them via the agent directory on the host or through the MID Server record in the instance if configured.

Answer

Via the System Mail log

Answer

Via the user profile

Answer

Via the Discovery Dashboard

Question 11

What is the purpose of the 'MID Server' log?

Accepted Answer

To store logs for troubleshooting the MID Server process. The MID Server log is specifically used to record events and errors related to the MID Server process itself. It is essential for troubleshooting issues such as connectivity, authentication, and job execution problems. The log is stored on the MID Server host and can be accessed for diagnostics.

Answer

To keep track of discovered CI data

Answer

To store credentials

Answer

To store user activity

Question 12

Why would you choose to use a 'Discovery Behavior' instead of the default behavior?

Accepted Answer

To limit or extend the probes used for specific discovery scenarios.. A Discovery Behavior is a configuration record that defines which probes and patterns run during discovery, allowing you to tailor the discovery process to specific device types or scenarios. By creating a custom Discovery Behavior, you can limit or extend the probes used, overriding the default behavior that applies to all devices. This is useful when certain devices require specialized probes or when you want to avoid unnecessary probes that could cause issues.

Answer

To update the CMDB identification rules.

Answer

To define the IP range for the discovery.

Answer

To change the schedule of the discovery.

Question 13

Which TWO of the following steps are required when adding a new CI relationship in a pattern?

Accepted Answer

Add 'Define Relationship' step. You need to identify the related CI and then define the relationship between them.

Answer

Add 'Modify Attribute' step

Answer

Add 'Validate' step

Answer

Add 'Delete CI' step

Question 14

Which THREE factors influence the successful identification of a CI in a pattern?

Accepted Answer

Correct identification rules in the CI Class Manager. Identification rules, attribute mapping, and valid CMDB class structure are critical.

Answer

Pattern execution speed

Answer

MID Server memory

Question 15

When configuring an IP Range for a Discovery Schedule, what format must be used for a block of IPs?

Accepted Answer

CIDR notation or start and end IP addresses.. ServiceNow Discovery IP Range records accept either CIDR notation (e.g., 10.10.0.0/24) or an explicit start and end IP address pair. Both formats define the contiguous block Shazzam will scan, and they are the only supported input formats for a range of IPs.

Answer

Wildcard characters like 10.10.*.*.

Answer

Subnet mask in decimal format.

Answer

A list of individual IP addresses separated by commas.
