 When configuring a REST Message, the Endpoint is:

• The URI of the data to be accessed, queried, or modified. This is the correct answer because the Endpoint is the part of the REST Message that specifies the location and the resource of the REST provider. The Endpoint is composed of the base URL and the resource path, which can include query parameters or variables. For example, the Endpoint for a REST Message that retrieves the weather information for a city from a web service could be https://api.openweathermap.org/data/2.5/weather?q=London.

The following are not correct definitions of the Endpoint when configuring a REST Message:

• The commands to the REST script to stop execution. This is not correct because the commands to the REST script to stop execution are not part of the REST Message, but of the Scripted REST API, which is a feature that allows users to create custom REST endpoints on the ServiceNow platform. The commands to the REST script to stop execution are methods of the RESTAPIResponse object, such as setStatusCode, setError, or complete.
• Information about the format of the returned data. This is not correct because the information about the format of the returned data is not part of the Endpoint, but of the HTTP headers or the Accept field of the REST Message. The HTTP headers or the Accept field can be used to specify the content type of the response, such as JSON, XML, or HTML.
• The response from the provider indicating there is no data to send back. This is not correct because the response from the provider indicating there is no data to send back is not part of the Endpoint, but of the HTTP status code or the response body of the REST Message. The HTTP status code or the response body can be used to indicate the result of the REST request, such as 200 OK, 404 Not Found, or 500 Internal Server Error. References: REST Messages, Scripted REST APIs

When evaluating Access Controls, ServiceNow searches and evaluates:

• From the most specific match to the most generic match. This is the correct answer because ServiceNow follows a top-down approach when evaluating Access Control (ACL) rules, which are used to restrict the access to the data and functionality of the ServiceNow platform based on the user’s roles and conditions. ServiceNow starts with the most specific match, which is the field-level ACL rule, then moves to the table-level ACL rule, and finally to the global or * ACL rule. ServiceNow grants access if any of the ACL rules evaluates to true, and denies access if all of the ACL rules evaluate to false.

The following are not correct descriptions of how ServiceNow searches and evaluates Access Controls:

• Only for matches on the current table. This is not correct because ServiceNow does not only look for matches on the current table, but also on the parent tables and the global or * table. For example, if there is no ACL rule for the incident table, ServiceNow will look for an ACL rule for the task table, which is the parent table of the incident table, and then for the global or * table, which is the parent table of all tables.
• Only for matches on the current field. This is not correct because ServiceNow does not only look for matches on the current field, but also on the table that contains the field and the global or * table. For example, if there is no ACL rule for the short_description field on the incident table, ServiceNow will look for an ACL rule for the incident table, and then for the global or * table.
• From the most generic match to the most specific match. This is not correct because ServiceNow does not follow a bottom-up approach when evaluating Access Controls, but a top-down approach, as explained above. References: Access Control Rules, ACL Evaluation Order

Catalog Client Scripts and Catalog UI Policies are the client-side scripts that apply to Record Producers. Catalog Client Scripts allow you to add or modify functionality on a catalog item or record producer form. Catalog UI Policies dynamically change information on a catalog item or record producer form. UI Scripts, UI Actions, Client Scripts, and UI Policies do not apply to Record Producers.
