SERVICENOW-CIS-DISCOVERY Quick Quiz — 10 Questions

Question 1

What is the primary way to check if a MID Server is communicating correctly with the ServiceNow instance?

Accepted Answer

Check the 'MID Server' list status.. The MID Server status on the 'MID Server' list view shows 'Up' if it is connected.

Answer

Check the Discovery log.

Answer

Ping the MID Server from your computer.

Answer

Check the CMDB.

Question 2

Where do you define the MID Server capabilities that allow it to perform specific tasks like Orchestration or Discovery?

Accepted Answer

In the MID Server record's 'Capabilities' related list.. MID Server Capabilities are managed via the 'Capabilities' related list on the MID Server record.

Answer

In the 'Discovery Definition' module.

Answer

In the 'MID Server Properties' module.

Answer

In the config.xml file.

Question 3

What is the purpose of the 'Pre-sensor' script?

Accepted Answer

To perform custom logic before the payload is processed.. Pre-sensor scripts allow developers to manipulate data before it is processed by the identification engine.

Answer

To stop a pattern from running.

Answer

To reset the MID server cache.

Answer

To run commands on the target device.

Question 4

Which of the following is a common symptom of a 'stale' CI?

Accepted Answer

The CI has not been updated by discovery within the expected timeframe.. A stale CI is one that has not been refreshed by the discovery source within the expected discovery/update window, meaning the CMDB record may no longer reflect the actual configuration. ServiceNow's CMDB Health 'staleness' KPI flags CIs whose 'last discovered' or 'updated' timestamp exceeds the configured threshold. This is the defining symptom of a stale CI.

Answer

The CI has a duplicate.

Answer

The CI has too many relationships.

Answer

The CI is missing required attributes.

Question 5

You are parsing a multi-line string containing key-value pairs separated by colons. Which tool is most appropriate for a single step extraction?

Accepted Answer

Parse Name-Value pair. The 'Parse Name-Value pair' step is designed to automatically extract multiple key-value pairs from a text block.

Answer

Regex

Answer

Parse Delimited

Answer

XPath

Question 6

When using 'Parse JSON' for a complex structure, how do you access a nested property named 'id' inside an array 'servers'?

Accepted Answer

servers[0].id. To access a nested property named 'id' inside an array 'servers' when using 'Parse JSON', you use the syntax servers[0].id. This is standard JSONPath-like notation where the array name is followed by the index in brackets, then a dot and the property name. This correctly retrieves the 'id' value from the first element of the 'servers' array.

Answer

servers->id

Answer

servers.id

Answer

id(servers)

Question 7

Which of the following correctly describes the use of the 'Pattern Designer's' 'Search' feature?

Accepted Answer

It allows locating specific steps or variables in the pattern.. The search feature allows you to find specific steps or configurations within a large, complex pattern.

Answer

It searches for available MID servers.

Answer

It searches for CIs in the CMDB.

Answer

It searches for patterns in the store.

Question 8

A MID Server is connected to the instance but 'Discovery' is not working. What is the most likely cause related to the MID Server configuration?

Accepted Answer

The MID Server lacks the 'Discovery' capability. The MID Server might not have the 'Discovery' capability assigned to it.

Answer

The MID Server is not validated

Answer

The MID Server is too old

Answer

The proxy is down

Question 9

Which action should you perform before modifying a default Discovery Pattern?

Accepted Answer

Create a copy of the pattern.. Default Discovery Patterns are shipped as read-only records that are overwritten during ServiceNow upgrades, so any direct modification would be lost. The supported practice is to create a copy of the pattern, modify the copy, and then activate it so the customized logic is preserved across upgrades. This also allows the original to remain available as a fallback if the custom pattern fails.

Answer

Export the pattern to an XML file.

Answer

Reboot the MID server.

Answer

Delete the original pattern.

Question 10

If a MID Server's 'Service' is running but the MID Server is 'Down' in the instance, what should you inspect?

Accepted Answer

The network connectivity and agent.config settings. If the service is up but the record is down, there is likely a network communication block or a configuration mismatch in agent.config.

Answer

The user's password in the instance

Answer

The MID Server's local disk space

Answer

The number of Discovery Schedules
