SNOW-CAD Core Application Development Practice Test 2 — 15 Questions

Question 1

An administrator sees that a client script on a catalog item is not firing. The script is defined in the catalog item's 'Variable Editor' as a 'onSubmit' script. Which is the most likely reason?

Accepted Answer

The script is written as a 'Catalog Client Script' but is defined in the 'Variable Editor' of the variable. The scenario describes a script defined in the catalog item's 'Variable Editor' as an 'onSubmit' script, which is a variable-level script. However, the question states the script is not firing. The most likely reason is that the script was written as a 'Catalog Client Script' (a global script type) but was incorrectly placed in the 'Variable Editor' of a variable. Variable-level scripts in the Variable Editor are executed only when that specific variable is present on the form; if the script is actually a Catalog Client Script (which runs on the entire catalog item), it would not execute as expected because it is scoped to the variable, not the item. This mismatch between the intended script type and its location causes the script to fail to fire.

Answer

The script is set to run on 'onLoad', but the page is being cached

Answer

The script is defined on a variable, but the variable is not on the order form

Answer

The script uses 'g_form' but the form is not loaded yet

Question 2

A developer is building a Flow in Flow Designer that needs to update an incident record when a certain event occurs. The flow uses a 'Update Record' action. However, the incident record is not being updated even though the flow runs without errors. What could be the issue?

Accepted Answer

The flow's application scope does not have write access to the Incident table. In ServiceNow, the application scope defines the permissions available to a flow. If the scope does not have write access to the Incident table, the 'Update Record' action may appear to run without throwing an error but the update is not persisted. This can occur if ACLs are configured to silently deny write operations for that scope. Other options like referencing the wrong table would typically log an error.

Answer

The flow trigger is set to 'On Created' but the incident already existed

Answer

The flow is using a 'Lookup Record' instead of 'Update Record'

Answer

The 'Update Record' action is referencing the wrong table

Question 3

A developer needs to create a UI Policy that hides a field when a checkbox is checked. The UI Policy has a condition: 'State is 2'. The field should be hidden when the checkbox is checked and state is 2. What is the correct approach?

Accepted Answer

Set condition to 'state=2' and add a script action that sets the field's visible attribute based on the checkbox value. The UI Policy condition 'State is 2' determines when the policy runs. To hide a field based on a checkbox value, you need a script action that evaluates the checkbox and sets the field's visible property accordingly. This approach allows dynamic control beyond static condition builder logic. The script action runs when the condition is true, and can check the checkbox value to decide visibility.

Answer

Add both conditions in the condition builder: checkbox=true AND state=2

Answer

Set condition to 'state=2' and add a reverse if false action with a condition on the checkbox

Answer

Use a Client Script instead of UI Policy

Question 4

A developer is configuring an approval flow for a catalog item. When a user submits a request, an approval record is created with a single approver. The approver must be the user's manager. Which is the correct way to set the approver?

Accepted Answer

In the catalog item, write an 'Approval script' that sets the approver to the submitted by user's manager using current.approver = current.caller_id.manager. It uses an approval script to dynamically set the approver to the manager of the request's caller. The script `current.approver = current.caller_id.manager` directly assigns the manager field from the user record of the caller, which is the standard way to implement a manager-based approval in ServiceNow. This approach is flexible and avoids hardcoding a specific user or group.

Answer

In the catalog item, set 'Approval type' to 'Single' and select a specific user

Answer

Use an Approval - User rule with condition that the approver is the manager

Answer

In the catalog item, set 'Approval type' to 'Group' and select the manager's group

Question 5

Which THREE are valid actions that can be performed by a Workflow Activity in Legacy Workflow Editor?

Accepted Answer

Run a script. The Legacy Workflow Editor includes a 'Run Script' activity that executes server-side JavaScript (GlideRecord, GlideSystem, etc.) within the workflow context. This allows custom logic such as data manipulation, condition checks, or API calls to be performed as part of the workflow flow.

Answer

Approve a record

Answer

Wait for condition

Question 6

The data policy is intended to require short description when category changes during an update. However, the short description is never made mandatory. Which issue exists?

Accepted Answer

The script uses setMandatory which is not available in Data Policies. `setMandatory()` is a client-side method used in client scripts or UI policies, not in data policies. Data policies run server-side and use `mandatory=true` on a dictionary element or `gs.addErrorMessage()` to enforce field requirements. Since the script attempts to call `setMandatory()` within a data policy, it will fail to make the short description mandatory, leaving the requirement unmet.

Answer

The table is Incident but the policy uses current.operation() incorrectly

Answer

The condition should use AND instead of OR

Answer

The policy should be of type 'Constraint'

Question 7

A developer needs to ensure that a catalog variable of type 'Reference' displays only active users from the sys_user table. Which property configuration should be applied to the variable?

Accepted Answer

Set 'Ref qual' to 'active=true'. The 'Ref qual' (Reference qualifier) property on a reference variable allows you to specify a condition to filter the records displayed in the lookup. Setting it to 'active=true' restricts the reference field to show only active users from the sys_user table, ensuring the developer meets the requirement.

Answer

Set 'Reference qual' to 'active=true'

Answer

Set 'Condition' to 'active=true'

Answer

Set 'Default value' to 'active=true'

Question 8

A developer creates a script include with client-callable true. The script include is used in a client script to validate a field. However, when the client script runs, it throws an error that GlideAjax is not defined. What is the most likely issue?

Accepted Answer

The client script is running in a UI policy instead of a client script.. The error 'GlideAjax is not defined' occurs when GlideAjax is used in a context that does not support it, such as a UI policy script. UI policies run on the server side and do not have access to client-side APIs like GlideAjax. Even though the script include is marked client-callable, the client script itself must be a true client script (e.g., onChange, onLoad) to use GlideAjax. Option B correctly identifies this scenario: the developer may have accidentally placed the script in a UI policy instead of a client script.

Answer

The script include is not marked as 'Client-callable'.

Answer

The script include is a global scope but the client script is in a scoped application.

Answer

The client script is not using the correct GlideAjax syntax.

Question 9

A developer needs to create a scheduled job that runs every Monday at 8 AM to update all incidents with a priority of '1' that are still open. Which condition script should be used in the scheduled job?

Accepted Answer

var gr = new GlideRecord('incident'); gr.addQuery('priority', 1); gr.addQuery('active', true); gr.query();. D is correct because it uses chained addQuery calls on a GlideRecord for the incident table to filter priority=1 and active=true, then executes the query to retrieve all matching records. Option A incorrectly uses GlideAggregate, which is intended for aggregation, not record retrieval. Option C incorrectly uses get with two arguments, which retrieves a single record and does not combine multiple conditions. Option B uses addEncodedQuery, which could produce the same results, but the single-answer item expects the standard programmatic approach using addQuery.

Answer

var gr = new GlideAggregate('incident'); gr.addQuery('priority', 1); gr.query();

Answer

var gr = new GlideRecord('incident'); gr.addEncodedQuery('priority=1^active=true'); gr.query();

Answer

var gr = new GlideRecord('incident'); gr.get('priority', 1); gr.get('active', true);

Question 10

A developer wants to restrict access to a specific record in the incident table so that only members of the 'ITIL' group can read it. Which type of ACL should be created?

Accepted Answer

Create a record-level ACL with a condition that checks group membership.. A record-level ACL with a condition that checks group membership is the correct approach because it controls read access to the entire record based on the user's group membership. In ServiceNow, record-level ACLs evaluate conditions against the user's session and the record's data, and if the condition (e.g., 'member of ITIL group') is false, the record is hidden from the user entirely. This directly meets the requirement to restrict read access to a specific incident record for only the 'ITIL' group.

Answer

Create a field-level ACL on the sys_id field.

Answer

Create a business rule to delete the record for unauthorized users.

Answer

Create a UI policy to hide the record.

Question 11

A developer is debugging an issue where a Script Action in a Flow Designer flow is not triggering. The flow is configured to run when a record is created or updated in the incident table. The Script Action is supposed to set a field based on a condition, but it never executes. What should the developer check first?

Accepted Answer

Check the flow's trigger conditions to ensure they match the record update.. The most common reason a Script Action fails to trigger is that the flow's trigger conditions do not match the record update event. Flow Designer evaluates trigger conditions before any actions execute; if the conditions are misconfigured (e.g., expecting a specific field change that isn't occurring), the entire flow, including the Script Action, will not run. The developer should first verify that the trigger conditions align with the actual record creation or update scenario.

Answer

Check if the flow is published.

Answer

Check if the script include used in the Script Action is accessible.

Answer

Check if the Script Action script has syntax errors.

Question 12

Which TWO of the following are valid ways to reference a sys_id of a record in a business rule? (Choose two.)

Accepted Answer

current.getUniqueValue(). Option B, current.getUniqueValue(), is correct because in ServiceNow server-side scripts this GlideRecord method returns the sys_id (the unique value) of the current record, making it a valid way to reference the sys_id in a business rule. Option C, current.get('sys_id'), is correct because GlideRecord.get() with the field name 'sys_id' retrieves the value of that field, which is the record's unique identifier. Option E, current.sys_id, is correct because GlideRecord exposes field values as properties, so accessing the sys_id field directly returns the unique ID. Option A, current.number, is not correct because number is a separate display field (such as INC0010001) and not the sys_id. Option D, current.getRow(), is not correct because getRow() returns the row number/position of the record in the result set, not the sys_id.

Answer

current.number

Answer

current.getRow()

Question 13

Which TWO of the following are true about client-callable script includes? (Choose two.)

Accepted Answer

They must have a function that returns a value.. Client-callable script includes must have at least one function that returns a value. This is required because the GlideAjax API processes the response asynchronously and expects a return value to be sent back to the client via the callback function. Without a return value, the client-side callback would receive undefined or null, breaking the intended data flow.

Answer

They can only be used in scoped applications.

Answer

They cannot be used in UI policies.

Answer

They can be called directly without GlideAjax if marked as synchronous.

Question 14

Which THREE of the following statements are true about ACLs? (Choose three.)

Accepted Answer

An ACL with 'require_role' set to true will only be checked after the user has at least one role in the ACL's role list.. Option A is correct because when an ACL has 'require_role' set to true, the role list acts as a gate: the ACL is only evaluated if the user possesses at least one of the roles in that list, otherwise the ACL is skipped. Option B is correct because in the absence of any ACL defined on a table, the platform's default behavior grants all users access to all records, so no restriction is applied. Option E is correct because ACLs support condition scripts that filter records, allowing access to be restricted to specific records based on script logic rather than just roles or fields. Option C is incorrect because ACL evaluation order is not determined by type and script condition in a deterministic ranking; ACLs are processed by matching rules and the first matching ACL decides, and conditions do not establish ordering. Option D is incorrect because ACLs govern data access (records and fields) and are not the mechanism used to enforce restrictions on server-side script execution.

Answer

ACLs are evaluated in a deterministic order based on the type (record, field, etc.) and the script condition.

Answer

ACLs can be enforced on server-side scripts.

Question 15

The exhibit shows a business rule script snippet. The business rule is triggered on 'before update' of incident table. When an incident's state is changed to 2 (Resolved), the short_description is set to 'Resolved'. However, the short_description is also being set to 'Resolved' when the state is already 2 and other fields are updated. Which change to the script would fix this issue?

Accepted Answer

Change 'current.state == 2' to 'current.state.changesTo(2)'.. Both options B and D correctly fix the issue. Option B uses `current.state.changesTo(2)`, a GlideRecord method that returns true only when the field's value changes *to* 2. Option D uses `current.state.changes() && current.state == 2`, where `changes()` returns true if the field is being updated (even if to the same value) and then checks the current value is 2. This also prevents triggering when other fields are updated without modifying the state. The original `current.state == 2` is true whenever the state is 2, regardless of change.

Answer

Change the trigger order from 'before' to 'after'.

Answer

Remove the condition and let the script run always.
