Question 2

A developer is creating a catalog item that requires a user to upload a file. Which variable type should be used?

Accepted Answer

Attachment. The Attachment variable type is specifically designed for file uploads in ServiceNow catalog items. It provides a built-in file picker and stores the uploaded file as an attachment on the requested record, enabling users to submit documents directly through the catalog form.

Answer

Multi Line Text

Answer

Single Line Text

Answer

Checkbox

Question 3

A developer needs to display a warning message to the user when a specific field value changes on a form, but the record should still be savable. Which approach should be used?

Accepted Answer

Create an 'onChange' Client Script using g_form.addErrorMessage() or g_form.showFieldMsg().. An 'onChange' Client Script runs on the client side when a specific field value changes, allowing the developer to display a warning message using g_form.addErrorMessage() or g_form.showFieldMsg() without preventing the record from being saved. This approach ensures the user sees the warning interactively while still being able to submit the form, which matches the requirement exactly.

Answer

Create a UI Policy with a condition and a UI message.

Answer

Create a Business Rule that uses gs.addErrorMessage().

Answer

Create a Data Policy for the field and set a warning message.

Question 4

A large enterprise runs ServiceNow on a single instance. They have a custom table 'u_project_task' that stores task details for projects. Each project task has a reference field to the 'u_project' table. The 'u_project' table has approximately 50,000 records, and the 'u_project_task' table has about 2 million records. Users report that opening a project record and viewing its related tasks takes over 30 seconds. The system uses an out-of-box related list to display tasks. The instance has standard hardware resources. The administrator has already confirmed that there are no performance issues with the database server or network. Which course of action should the administrator take to improve the performance of the related list?

Accepted Answer

Create a database index on the 'u_project' field in the 'u_project_task' table to speed up the join.. The performance bottleneck is the database query that joins the large 'u_project_task' table (2M records) with the 'u_project' table on the reference field. Without an index on the 'u_project' field in 'u_project_task', the database must perform a full table scan for each related list query. Creating a database index on that foreign key column allows the database to use an index seek, dramatically reducing query time.

Answer

Archive project tasks older than 1 year to a separate table to reduce the data volume.

Answer

Increase the glide.ui.related_list.max_timeout property to allow the query more time.

Answer

Add additional application nodes to the instance to distribute the load.

Question 5

Drag and drop the steps to create an ACL (Access Control List) in ServiceNow into the correct order.

Accepted Answer

Navigate to ACLs, then create a new ACL record, then define the type, operation, and name, then set the condition, then submit.. The sequence: navigate to ACLs, create new, define type/operation/name, set condition, and submit.

Answer

Define the type, operation, and name, then navigate to ACLs, then create a new ACL record, then set the condition, then submit.

Answer

Set the condition, then navigate to ACLs, then create a new ACL record, then define the type, operation, and name, then submit.

Answer

Create a new ACL record, then navigate to ACLs, then define the type, operation, and name, then set the condition, then submit.

Question 6

An organization uses an LDAP integration to import user accounts into ServiceNow. The integration creates a large number of users, but some users are missing their manager field. The manager field in LDAP is a distinguished name (DN). The transform map uses a reference field mapping with "Display value" unchecked. The target field "manager" on sys_user is a reference to sys_user. The import set log shows no errors for those records. What is the most likely cause?

Accepted Answer

The LDAP DN values do not match the sys_id of the manager users.. The manager field is a reference to sys_user. When mapping an LDAP DN (distinguished name) to a reference field with 'Display value' unchecked, the system expects a sys_id or a value that can be matched via a reference qualifier. Since the DN is not a sys_id and no other matching logic is applied, the mapping fails silently, leaving the field empty. The import set log shows no errors because the transformation completes but the field is not populated.

Answer

The transform map's "Coalesce" field is set on manager.

Answer

The import set's "On Conflict" setting is set to "Ignore".

Answer

The manager field in LDAP is empty for some users.

Question 7

A developer notices that the business rule does not set the assignment group as expected when a new record is created with state 0. What is the most likely issue?

Accepted Answer

The assignment_group value is not a valid sys_id of a group.. The most likely issue is that the assignment_group value provided in the script is not a valid sys_id of an existing group. In ServiceNow, the assignment_group field is a reference field to the sys_user_group table, and it must contain a valid sys_id. If the sys_id is invalid or does not exist, the field will not be set, and the business rule will appear to have no effect.

Answer

The script has a syntax error.

Answer

The business rule runs after the record is saved, so updates are ignored.

Answer

The business rule condition is incorrect.

Question 8

A developer is testing a REST API call to retrieve active users with the ITIL role created since last month. The response returns an error. What is the most likely cause?

Accepted Answer

The query parameter sysparm_query uses a script which is not allowed in REST API calls.. The error occurs because the sysparm_query parameter in a REST API call to the /api/now/table/sys_user endpoint does not support scripts; it only accepts encoded query strings using operators like '=', '^', 'STARTSWITH', etc. Using a script in sysparm_query violates the REST API specification, which expects a simple query string, not executable code, leading to a bad request error.

Answer

The Accept header should be application/xml.

Answer

The endpoint should be /api/now/table/sys_user_list.

Answer

The query should use sysparm_fields instead of sysparm_query.

Question 9

A company has developed a custom Scripted REST API endpoint that processes incoming orders and then makes synchronous outbound REST calls to an external shipping system for validation. During testing with low concurrency, the endpoint works correctly. However, in production with high concurrency, the endpoint frequently times out and returns 504 errors to the caller. The performance team has confirmed that the external shipping system is responsive and the network latency is acceptable. Which course of action should the development team take to resolve the timeout issue?

Accepted Answer

Refactor the script to make asynchronous HTTP requests and process the shipping validation response using a separate queue or business rule.. The issue is that synchronous outbound REST calls block the incoming request thread, and under high concurrency, threads are exhausted, causing timeouts and 504 errors. Refactoring to asynchronous HTTP requests allows the incoming request to complete quickly, while the shipping validation response is processed separately via a queue or business rule. This decouples the processing and scales better under load.

Answer

Deploy additional MID Servers to distribute the outbound call load.

Answer

Implement a caching layer to store shipping validation results and avoid repeated calls to the external system.

Answer

Increase the timeout value in the outbound REST Message record to accommodate peak loads.

Question 10

Drag and drop the steps to create a new table in ServiceNow into the correct order.

Accepted Answer

Navigate to System Definition > Tables, then click New, then define table properties (label, name, etc.), then set attributes (extends, access, etc.), then submit.. The order is: navigate to tables, click new, define table properties, set attributes, then submit.

Answer
