NEW QUESTION # 16
Which server-side API debug log method is available for scoped applications?
Answer: B
Explanation:
In ServiceNow, the gs object provides a range of methods for logging messages on the server side. However, the availability of these methods can vary depending on whether the application is global or scoped.
* gs.info(): This method is available in scoped applications and is used to log informational messages to the system log. It provides a way to record general information during script execution.
Options A (gs.log()), B (gs.print()), and D (gs.debugLog()) are not available in scoped applications. These methods are either restricted to global applications or do not exist in the ServiceNow API.
For more detailed information, refer to the official ServiceNow documentation on server-side scripting:
NEW QUESTION # 17
Which database operations can be controlled with Application Access? (Choose 2 answers)
Answer: A,B
Explanation:
Application Access settings on a table control which operations external applications (in other scopes) can perform. The main controllable operations are:
* Can create
* Can read (query)
* Can update
* Can delete
From Development Handbook 4.0.4, p. 192:
"Application access settings determine whether another scope can read, write, create, or delete records from this table... Execute is not a valid database operation - it pertains to script includes or other executable logic."
NEW QUESTION # 18
Can inherited fields be deleted from a table?
Answer: B
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:Inherited fields in ServiceNow are fields that are part of a parent table and automatically become part of child tables through inheritance. This structure is foundational in the ServiceNow data model, ensuring that child tables maintain a consistent relationship with their parent tables.
Here's why inherited fields cannot be deleted from a child table:
* System Design:ServiceNow employs a table inheritance model where child tables derive fields and properties from parent tables. Deleting inherited fields from a child table would break the integrity of the data model, as those fields are shared across multiple tables.
* Impact on Functionality:Many inherited fields, such as sys_created_on or sys_updated_by, are integral to the functionality of the platform. Removing them could disrupt workflows, reporting, and auditing capabilities.
* Alternative Approach:If you want to hide or restrict access to inherited fields in a child table, you can use ACLs (Access Control Lists) to prevent users from viewing or modifying these fields. Another option is to use UI Policies or Client Scripts to control their visibility on forms.
* Developer Note:Attempting to delete inherited fields violates ServiceNow's core principles of maintaining a robust and unified data structure. The platform enforces these rules to ensure consistent behavior across all tables in the hierarchy.
References:
* ServiceNow Developer Documentation on Table Inheritance.
* Best practices outlined on SN Pro Tips regarding scoped application development and table structures.
NEW QUESTION # 19
What is the Event Registry?
Answer: C
Explanation:
In ServiceNow, the Event Registry is a table that contains a record for every event recognized by the system. It allows ServiceNow to respond when these events are generated. By registering events, the system can automate activities such as triggering notifications or executing script actions when specific events occur. Therefore, the correct answer is A.
The other options are not accurate descriptions of the Event Registry:
B . The Event Log which lists all Events that have been generated: This describes the Event Log, not the Event Registry.
C . A Workflow which is launched every time an Event is generated; used to debug Events: This is not how the Event Registry functions.
D . The method used in server-side scripts to generate Events and pass parameters: This describes the gs.eventQueue() method, not the Event Registry.
For more detailed information, refer to the official ServiceNow documentation on the Event Registry.
