Pg 126 of the CAD handbook The method that prints a message on a blue background to the top of the current form by default is g_form.addInfoMessage(). The g_form object is a global object that provides access to form fields and UI elements on a form. The addInfoMessage() method is a method of the g_form object that displays an informational message next to the form header. The message has a blue background color by default, unless it is overridden by a CSS style. The addInfoMessage() method takes one argument, which is the message text to display.

The correct combination of statements is a, b, and d. These are possible reasons to build custom applications on ServiceNow:
To replace outdated, inadequate, custom business applications and processes. Building custom applications on ServiceNow can help digitize and automate manual or legacy processes that are not covered by existing ServiceNow solutions. This can improve efficiency, data quality, user experience, and innovation.
To extend service delivery and management to all enterprise departments. Building custom applications on ServiceNow can help provide consistent and scalable services across different functions and teams in the organization. This can enhance collaboration, visibility, productivity, and customer satisfaction.
To extend the value of ServiceNow. Building custom applications on ServiceNow can help leverage the capabilities and benefits of the Now Platform®, such as low-code development tools, workflow automation engine, AI-powered insights, security operations, etc. This can increase agility, resilience, performance, and value.
The statement c is not a valid reason to build custom applications on ServiceNow:
To allow users full access to all ServiceNow tables, records, and fields. Building custom applications on ServiceNow does not imply granting users full access to all data and objects in ServiceNow. Access control rules still apply to custom applications and their components to ensure security and compliance. Reference: Build Custom Apps in ServiceNow - eBook
