SERVICENOW-CIS-DISCOVERY Discovery Pattern Design Practice Test 3 — 15 Questions

Question 1

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. You use dot-notation (or specific path syntax) to navigate the JSON structure.

Answer

servers->id

Answer

servers.id

Answer

id(servers)

Question 2

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 3

Which action must you perform before a pattern can be used in Discovery?

Accepted Answer

Publish the pattern.. Patterns must be published to be active in the production environment.

Answer

Run a full scan.

Answer

Add it to an Update Set.

Answer

Clear the MID Server cache.

Question 4

What is the result of using a 'Delimiter' of '
' in a 'Parse Delimited' step?

Accepted Answer

It splits the text into separate lines (rows).. The '
' (newline) delimiter splits the text into separate rows.

Answer

It splits the text into individual characters.

Answer

It removes all spaces.

Answer

It converts the text to JSON.

Question 5

Which of the following is true about 'Identification Sections'?

Accepted Answer

They must be the first section in the pattern.. An identification section must contain at least one step that identifies the CI.

Answer

They are optional.

Answer

They don't support regex.

Answer

They can only be used once per pattern.

Question 6

What is the purpose of 'Discovery' patterns?

Accepted Answer

To populate the CMDB with CI data.. Discovery patterns are used to populate the CMDB with CI data from infrastructure components.

Answer

To generate incident reports.

Answer

To manage user access.

Answer

To create business services.

Question 7

When a pattern step fails, how can you determine which step caused the failure?

Accepted Answer

Review the Discovery Status record log.. The Discovery status log shows the step that failed in the execution flow.

Answer

Re-run the Discovery as admin.

Answer

Check the MID Server service.

Answer

Look at the CMDB class manager.

Question 8

What is the difference between 'Identification' and 'Connection' in terms of CI ownership?

Accepted Answer

Identification handles the primary CI; Connection links it to dependent CIs.. The Identification section identifies the 'primary' CI, while Connection links it to others.

Answer

There is no difference.

Answer

Connection creates the CI; Identification sets attributes.

Answer

They are the same.

Question 9

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 10

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 11

Which TWO of the following are valid ways to pass data between pattern sections?

Accepted Answer

Pattern parameters. You can use variables or the 'Global' scope to share data across steps and sections.

Answer

Discovery Logs

Answer

CMDB Tables

Answer

System Properties

Question 12

Which THREE of the following are common parsing strategies used in pattern design?

Accepted Answer

Regex. Common strategies include Regex, JSON, and Delimited text parsing.

Answer

SQL Queries

Answer

Java Class

Question 13

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

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

Answer

Delimiter parsing

Answer

Regex

Answer

JSON parsing

Question 14

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

Accepted Answer

Answer

Add 'Modify Attribute' step

Answer

Add 'Validate' step

Answer

Add 'Delete CI' step

Question 15

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
