CAD Exam Dumps - Certified Application Developer - ServiceNow

Understanding Scoped Applications:Scoped applications in ServiceNow are designed to isolate and protect application-specific code and data. Server-side scripts within scoped applications can use the gs (GlideSystem) object for logging and debugging purposes. However, not all gs methods are appropriate or valid for scoped applications.

Valid Logging Methods in Scoped Applications:

gs.info():This method logs informational messages to the system log. It is commonly used for general-purpose logging when developers need to track execution flow or display debug data. Example:

gs.info('This is an informational log message.');

gs.error():This method logs error messages to the system log. It is used to indicate problems or issues encountered during script execution. Example:

gs.error('An error occurred during script execution.');

Incorrect Options Explained:

gs.debug() (Option B): This method is not valid in scoped applications. It is a legacy logging method available in the global scope but restricted in scoped applications.

gs.iog() (Option C): This is a typographical error and not a valid gs method in ServiceNow.

gs.logError() (Option E): This is not a recognized ServiceNow API method. To log errors, gs.error() is used instead.

Best Practices for Logging:

Logging should be meaningful and avoid unnecessary entries to keep logs clean and manageable.

Avoid excessive use of logging in production environments, as it can clutter the system logs and potentially degrade performance.

 It is best practice to define the business requirements and the process(es) an application will manage as part of the application development plan. The following are some of the considerations to document as part of the business process:

Business problem. This is the description of the problem or opportunity that the application is intended to address or exploit. It should include the background, context, scope, and objectives of the problem or opportunity.

Data input/output. This is the specification of the data that the application will need to collect, store, manipulate, and display. It should include the data sources, formats, validations, transformations, and integrations of the data.

Users/stakeholders. This is the identification of the users and stakeholders who will be involved in or affected by the application. It should include the roles, responsibilities, expectations, and needs of the users and stakeholders.

Process steps. This is the definition of the steps and activities that the application will perform or support. It should include the inputs, outputs, triggers, conditions, and outcomes of each step or activity.

The following are not some of the considerations to document as part of the business process:

Project schedule. This is the estimation of the time and resources required to complete the application development project. It should include the milestones, deliverables, dependencies, and risks of the project. This is not part of the business process, but part of the project management plan.

Database capacity. This is the measurement of the amount of data that the application will generate and store in the database. It should include the data volume, growth rate, retention policy, and backup strategy of the data. This is not part of the business process, but part of the technical design and architecture of the application.

Available licenses. This is the number and type of licenses that the application will consume or require from the ServiceNow platform. It should include the license model, cost, and allocation of the licenses. This is not part of the business process, but part of the financial and legal aspects of the application. References: Application Development Process, Business Process Analysis

An application admin is a role that grants full access to an application and its tables, scripts, and other components1. An application admin can create, modify, and delete any element of the application, as well as publish and install it2. An application typically has an application admin role that is automatically created and assigned to the application creator3.

Web services are software systems that use standardized protocols and formats, such as XML and HTTP, to exchange data and messages between different applications or systems over the Internet or other networks12. Web services enable interoperability and integration among diverse software components, regardless of their programming languages, platforms, or architectures34.
