SNOW-CAD Practice Test 14 — 15 Questions

Question 1

The business rule has an empty script. What will happen when an incident state changes to 'Resolved'?

Accepted Answer

Nothing, because there is no script.. Option A is correct because an empty script does nothing; no action is taken. Option B is incorrect because there are no default actions. Option C is incorrect because a script is not required. Option D is incorrect because the condition is valid.

Answer

The business rule will not fire because condition is invalid.

Answer

The business rule will cause an error because script is required.

Answer

The business rule will still fire and execute default actions.

Question 2

A developer writes a business rule that runs on after update. The script intends to send an email notification when the priority changes. Which method should be used to compare the previous and current values?

Accepted Answer

current.priority.changes(). The changes() method on a field object returns true if the field changed. Option B is correct. Option A checks if any field changed. Option C uses direct comparison but is not a method. Option D uses getDisplayValue which compares labels, not values.

Answer

current.getDisplayValue('priority') != previous.getDisplayValue('priority')

Answer

current.changes()

Answer

previous.priority != current.priority

Question 3

Refer to the exhibit. The business rule is intended to update the CI's operational status when an incident is resolved. However, the CI is not being updated. What is the most likely reason?

Accepted Answer

The script does not include a condition to check if the CI belongs to the cmdb_ci_server table. The script assumes the CI record is of type 'cmdb_ci_server'. If the CI is a different class (e.g., cmdb_ci_router), the GlideRecord will not find it. Option A is incorrect because after business rules can update other records. Option B is not the root cause. Option C is false because synchronous rules can update other records.

Answer

The business rule runs after the record is saved, so changes to the CI are not saved

Answer

The business rule runs synchronously, so it cannot update another record

Answer

The script uses gr.update() without checking if the CI record exists

Question 4

Which three actions require a business rule to be set to 'before' to work correctly? (Choose three.)

Accepted Answer

Setting a default value on a new record. Options A, B, and D are correct. A: Aborting the transaction must happen before the database write. B: Setting a default value must happen before insert. D: Updating a field on the current record is only possible in 'before' (in 'after' the record is already saved). C and E can be done in 'after' as well.

Answer

Sending an email notification

Answer

Deleting a record related to the current record

Question 5

A developer creates a business rule that runs before a record is inserted or updated on the Incident table. The rule sets the assignment group based on the category. However, after the rule runs, the assignment group is not being saved. What is the most likely cause?

Accepted Answer

The rule runs after the record is saved. If the rule runs after the record is saved, changes to current are not automatically saved. The script must call current.update(). Options A and B are not relevant. Display business rules run on the client side.

Answer

The rule is a display business rule

Answer

The business rule is set to run on before update only

Answer

The script does not use current.setAbortAction(false)

Question 6

A developer is tasked with writing a business rule that should only execute when the record is being updated and the value of the 'state' field changes from 'In Progress' to 'Resolved'. Which condition should be used in the business rule?

Accepted Answer

current.operation() == 'update' && current.state.changesFrom('In Progress') && current.state.changesTo('Resolved'). The changesFrom() and changesTo() methods are the recommended approach for checking field transitions. Options A and D use direct comparison but are less efficient. Option C only checks that state changed, not the specific transition.

Answer

current.operation() == 'update' && previous.state == 'In Progress' && current.state == 'Resolved'

Answer

current.operation() == 'update' && current.state.changes() && current.state == 'Resolved'

Answer

current.operation() == 'update' && current.state == 'Resolved' && previous.state == 'In Progress'

Question 7

A company has a business rule that runs after a record is inserted on the Change Request table. The rule creates a related task record. Recently, the rule stopped working for some users. The developer discovers that the rule fails silently when the logged-in user lacks the 'change_request.create' role. What is the best way to fix this?

Accepted Answer

Set the rule to run as the system user. Setting the business rule to run as the system user bypasses role-based restrictions. Option A would prevent execution. Option C does not handle the error. Option D is unnecessary.

Answer

Use gs.hasRole('change_request.create') to check and abort if false

Answer

Move the script to a script action that runs in the background

Answer

Use current.setAbortAction(false) to ignore the error

Question 8

A developer is creating a business rule to automatically assign tasks to a specific group based on the category. The rule is set to run before insert and update on the Task table. The script uses current.assignment_group = 'IT Support'. However, the assignment group is not being set on update even though it works on insert. Which three potential causes should the developer investigate? (Choose three.)

Accepted Answer

The business rule's condition field requires the category to be set. Option A: if the condition depends on category, on update the category might not trigger the rule. Option C: if the script only runs on insert conditionally, it won't run on update. Option E: another rule might override the group. Option B: scope is not an issue. Option D: read-only fields can be set in business rules.

Answer

The assignment group field is read-only on the form but can be set via business rule

Answer

The business rule is set to run only in the global scope

Question 9

A scheduled import brings in 50,000 records daily. Which approach is the MOST efficient for transforming these records?

Accepted Answer

Load all rows first, then run the transform as a batch process. Option C is correct: running transform after all rows are loaded in batch is efficient. Option A is wrong because transforming each row individually is slower. Option B is wrong because database views are not for import transformation. Option D is wrong because directly using import set row table bypasses transform logic.

Answer

Run the transform after each row is inserted into the staging table

Answer

Use a database view to transform data on the fly

Answer

Write directly to the target table using insert statements

Question 10

What is the purpose of the 'Coalesce' field in a transform map?

Accepted Answer

To use a field to match existing records and avoid duplicates.. The Coalesce field is used to specify which fields to use for matching existing records to avoid duplicates during import.

Answer

To remove null values from the import.

Answer

To combine multiple fields into one.

Answer

To convert data types.

Question 11

Refer to the exhibit. A MID Server is failing to connect to an external Oracle database. The error log shows the above message. Which is the most likely cause?

Accepted Answer

The database instance name (service name) is incorrect in the configuration.. Error ORA-12514 indicates that the listener received a connection request but the service name (in the connect descriptor) is not known to the listener. This usually means the database service name is incorrect or the listener is not configured for that service.

Answer

The firewall is blocking port 1521.

Answer

The Oracle client is not installed.

Answer

The MID Server is not running.

Question 12

An organization needs to import data from a SaaS application that provides a CSV file accessible via a direct URL. Which data source type should be configured?

Accepted Answer

File data source. Option D is correct: File data source can import from a URL. Option A is wrong because LDAP is for directory services. Option B is wrong because JDBC is for SQL databases. Option C is wrong because REST is for web services.

Answer

REST data source

Answer

JDBC data source

Answer

LDAP data source

Question 13

A company wants to synchronize user data from an external HR system into ServiceNow every night. The HR system pushes a CSV file to an SFTP server. Which ServiceNow feature should be used to automate this process?

Accepted Answer

Scheduled Import. Scheduled Import from an SFTP server is the proper feature to automate ingestion of files from an external SFTP location at scheduled intervals.

Answer

External Data Source

Answer

SOAP Web Service

Answer

REST API

Question 14

Which THREE of the following are features available in ServiceNow for integrating data with external systems? (Choose three.)

Accepted Answer

SOAP Web Service. REST API, SOAP Web Service, and LDAP are standard integration features in ServiceNow. Email and Print are not used for data integration.

Answer

Email

Answer

Print

Question 15

A company uses REST API to push data from ServiceNow to an external system. The authentication keeps failing with HTTP 401. They have set up OAuth 2.0 client credentials grant. What is the most likely cause?

Accepted Answer

Wrong token endpoint URL. Option B is correct because in client credentials grant, the token endpoint must be correct. Option A is wrong because missing client ID would cause a different error. Option C is wrong because HTTPS is required but not the most likely cause of 401. Option D is wrong because client credentials grant does not use refresh tokens.

Answer

Missing client ID in the request

Answer

Using HTTP instead of HTTPS

Answer

Refresh token has expired
