SERVICENOW-CIS-DISCOVERY Discovery Pattern Design Practice Test 4 — 15 Questions

Question 1

What is the primary role of the MID Server during pattern execution?

Accepted Answer

To execute the pattern commands on the target.. The MID Server executes the commands on the target on behalf of the instance.

Answer

To define pattern logic.

Answer

To store the CMDB.

Answer

To design the pattern.

Question 2

When a pattern step needs to run as root, where is this configuration set?

Accepted Answer

In the step properties, 'Run as' field.. The 'Run as' field in the step properties allows you to specify the execution context (e.g., sudo/root).

Answer

In the MID Server property.

Answer

In the Discovery Schedule.

Answer

This cannot be done in a pattern.

Question 3

What is the purpose of the 'Table' attribute in the 'Identification' step?

Accepted Answer

To specify the target CMDB class.. The 'Table' attribute defines which CMDB class the identified CI belongs to.

Answer

To set the CI relationship type.

Answer

To filter the input data.

Answer

To name the variable.

Question 4

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 5

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 6

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 7

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 8

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 9

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 10

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 11

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 12

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 13

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

Accepted Answer

Regex. Regex (A) is a common parsing strategy because regular expressions define character-level patterns that are matched against input text to extract or validate fields. JSON (C) is a common parsing strategy because its structured key-value and array syntax is parsed by dedicated JSON parsers to navigate and extract data reliably. Delimited text (E) is a common parsing strategy because records and fields separated by delimiters such as commas, tabs, or pipes are split and tokenized to obtain individual values. SQL Queries (B) are a data retrieval and manipulation language, not a parsing strategy for pattern design, and Java Class (D) is a programming construct or data model, not a parsing approach.

Answer

SQL Queries

Answer

Java Class

Question 14

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 15

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
