The Guided Application Creator (GAC) is a tool that helps you create applications on the ServiceNow platform by guiding you through the steps of defining the data model, user interface, and logic. When using the GAC, you can designate data tables in three ways:
Upload an existing PDF: You can upload a PDF file that contains the table schema and sample data. The GAC will parse the PDF and create the table and fields based on the file content.
Create a new table on the platform: You can create a new table on the platform by specifying the table name, label, and description. You can also add fields, indexes, and relationships to the table using the GAC.
Upload an existing spreadsheet: You can upload a spreadsheet file that contains the table schema and sample data. The GAC will parse the spreadsheet and create the table and fields based on the file content.
The other options are not valid ways to designate data tables when using the GAC. You cannot upload an existing word processing document or use a freeform database. You can use an existing table on the platform, but you cannot designate it as a data table. You can only use it as a reference table for lookup fields.

The following roles grant access to source control repository operations such as importing applications from source control, or linking an application to source control:
source_control. This is a role that allows users to perform basic source control operations, such as importing an application from a source control repository, updating an application from a source control repository, or committing changes to a source control repository.
admin. This is a role that grants full access to all the features and functions of the ServiceNow platform, including source control operations. Users with this role can also perform advanced source control operations, such as creating or deleting source control repositories, configuring source control properties, or resolving conflicts.
The following roles do not grant access to source control repository operations:
source_control_admin. This is not a valid role in ServiceNow. There is no separate role for source control administration, as this function is included in the admin role.
git_admin. This is not a valid role in ServiceNow. Git is a specific type of source control system that ServiceNow supports, but there is no role dedicated to Git administration. References: Source Control, Source Control Roles

In ServiceNow, the GlideSystem (gs) object provides several methods for logging messages in server-side scripts. In a privately-scoped application, the following methods are commonly used:
* A. gs.log(): This method logs a message to the system log (syslog table). It is a general-purpose logging method that allows developers to record informational messages.
* E. gs.info(): This method logs informational messages to the system log. It is functionally similar to gs.
log() but is specifically intended for informational messages.
The other options are not standard methods provided by the GlideSystem object:
* B. gs.error(): This method does not exist in the GlideSystem API.
* C. gs.debug(): This method does not exist in the GlideSystem API.
* D. gs.logError(): This method does not exist in the GlideSystem API.
For more detailed information, refer to the official ServiceNow documentation on the GlideSystem API.
