SNOW-CAD Practice Test 3 — 10 Questions

Question 1

Refer to the exhibit. A developer created this Script Include to be used as a REST API endpoint. However, when calling the API, the response is empty. What is the most likely reason?

Accepted Answer

The Script Include is not marked as 'REST API endpoint' or does not extend the appropriate class.. Option D is correct because a Script Include used as a REST API endpoint must either extend the appropriate class (such as 'RESTAPI' or 'RESTAPIV2') or be explicitly marked as a REST API endpoint in its definition. Without this, the platform does not recognize it as a valid endpoint, resulting in an empty response when the API is called.

Answer

The Script Include is not marked as 'Client callable'.

Answer

The function name 'getOpenIncidents' is not exposed.

Answer

The GlideRecord query returns no results.

Question 2

A company is building a ServiceNow application to manage employee onboarding. They need to store personal data like social security numbers (SSNs) and medical information. Which data classification scheme should they apply to these fields to ensure proper encryption and access controls?

Accepted Answer

Highly Confidential. Option C is correct because 'Highly Confidential' is the ServiceNow data classification level designed for sensitive personal data such as social security numbers and medical information. This classification enforces mandatory encryption at rest and in transit, strict role-based access controls, and audit logging, aligning with regulatory requirements like GDPR and HIPAA.

Answer

Confidential

Answer

Internal

Answer

Public

Question 3

A developer is troubleshooting a business rule in a scoped application that is not triggering. The rule is set to run 'before' query, with condition 'current.state == 1'. The table has read ACLs that restrict access. What is the most likely reason the business rule is not executing?

Accepted Answer

The user does not have read access to the records, so the query does not execute the rule.. Business rules that run 'before query' execute when a query is made against the table. If the user lacks read access due to ACL restrictions, the query itself is not permitted, so the business rule never triggers. This is because the platform's security layer evaluates ACLs before executing business rules, preventing the rule from running when the user cannot read the records.

Answer

The condition 'current.state == 1' is incorrect syntax.

Answer

Another business rule with higher order is preventing execution.

Answer

The business rule is scoped and cannot access the table.

Question 4

A company has a custom table 'u_employee' with fields: 'first_name', 'last_name', 'department'. They want to create a unique index on the combination of 'last_name' and 'department' to prevent duplicate entries. Where should this index be defined?

Accepted Answer

In the table's dictionary record via the Indexes related list. In ServiceNow, a unique index on a custom table is defined in the table's dictionary record via the Indexes related list. This is the correct location because ServiceNow uses the table's dictionary metadata to manage indexes, and the Indexes related list allows you to specify unique constraints directly on the table definition, ensuring the database enforces uniqueness on the combination of 'last_name' and 'department'.

Answer

In the table schema map

Answer

In the dictionary entry for each field

Answer

In the sys_dictionary table directly

Question 5

A developer creates a business rule on the Incident table that executes a GlideRecord query to update related records. The rule runs on 'after' update and queries the Problem table to set a field. However, the update is not being committed. What is the most likely reason?

Accepted Answer

The GlideRecord query requires an explicit gr.updateMultiple() or gr.commit() to persist changes.. In ServiceNow, when a GlideRecord query is used in an 'after' business rule to update records on another table, the changes are not automatically committed. The developer must explicitly call gr.updateMultiple() to persist updates to multiple records, or gr.update() for a single record. Option B correctly identifies this requirement, as the update is not being committed without an explicit method call.

Answer

The developer forgot to use gr.insert() instead of gr.update().

Answer

After business rules cannot update other tables.

Answer

The query returns more than 100 records, causing a governor limit.

Question 6

A ServiceNow administrator notices that a business rule designed to update the 'short_description' field on the 'incident' table is not executing when a user changes the field via a custom UI page that uses GlideRecord. The script in the business rule uses current.setValue() and current.update(). What is the most likely cause?

Accepted Answer

The business rule is set to run on the server, but the custom UI page uses client-side GlideRecord which does not trigger server-side business rules.. Option C is correct because client-side GlideRecord (g_form.getReference or direct GlideRecord in a UI page) runs entirely in the browser and does not trigger server-side business rules. Business rules execute only when a record is saved via server-side operations (e.g., form submit, web service, or server-side script). Since the custom UI page uses client-side GlideRecord, the update bypasses the business rule engine entirely.

Answer

The 'short_description' field is read-only on the form.

Answer

The business rule is updating itself recursively and has been disabled.

Answer

The 'short_description' field is not in the business rule's 'Fields to update' list.

Question 7

A developer is designing a custom application with a table that stores sensitive employee data. The requirement is that only managers can view records where they are the manager of the employee. Which two configurations are needed to implement this requirement?

Accepted Answer

Use a UI Policy to set fields to read-only or invisible for non-managers. Option A is correct because UI Policies can be configured to set fields as read-only or invisible based on conditions, such as the user's role or relationship to the record. This allows non-managers to see the record but prevents them from viewing sensitive fields, aligning with the requirement to restrict visibility at the field level.

Answer

Create a new view that excludes sensitive fields

Answer

Create a Business Rule that deletes records if the user is not the manager

Answer

Use a Client Script to hide fields if the user is not the manager

Question 8

A company is integrating ServiceNow with an external ticketing system using a custom REST API. The integration should push updates from ServiceNow to the external system when a change request is approved. Which ServiceNow feature is best suited for this?

Accepted Answer

Business Rule with outbound REST call. A Business Rule with an outbound REST call is the best fit because it triggers automatically on the 'approved' state change of a change request and can execute a synchronous or asynchronous REST API call to the external ticketing system. This allows real-time push of updates without manual intervention or polling, directly meeting the requirement to push updates upon approval.

Answer

REST API Explorer

Answer

Access Control List (ACL)

Answer

Scheduled Job

Question 9

An organization uses ServiceNow Discovery to populate the CMDB. They notice that some CI relationships are missing after a discovery run. The discovery logs show no errors. What is the most likely cause?

Accepted Answer

The CI Class Manager does not have the correct relationship types defined for the discovered CIs. Option B is correct because the CI Class Manager defines which relationship types are valid for each CI class. If the relationship types are not defined or incorrectly configured, Discovery will not create those relationships even if the probes run successfully and no errors are logged. The absence of errors indicates the discovery process completed normally, but the missing relationships are due to missing or incorrect relationship definitions in the CI Class Manager.

Answer

The MID server credentials do not have permission to query relationship data

Answer

The discovery probes are not configured to capture relationships

Answer

The CMDB is set to read-only mode

Question 10

A ServiceNow admin is troubleshooting a data import from an external database via JDBC. The import runs successfully but only loads partial data. Which is the most likely cause?

Accepted Answer

The JDBC driver has a default row limit that caps the number of records imported. JDBC drivers often impose a default row limit (e.g., 10,000 rows) to prevent memory overload during data retrieval. When importing from an external database via JDBC, this limit caps the number of records returned, causing only partial data to load even though the import job completes successfully. The admin must explicitly set the fetch size or disable the row limit in the JDBC URL or driver configuration to import all records.

Answer

The scheduled import job was interrupted by another job

Answer

The transform map has a filter that excludes certain records

Answer

The field mapping is incorrect and some fields are not being populated
