Explanation
The Unpublished Revision status on a guide tile indicates that the guide has been previously published, but has been modified and not published again. This means that the changes made to the guide are not visible to the end users in the production environment, and only the original version of the guide is displayed. The Unpublished Revision status allows the content developer to test and preview the changes before publishing them. To publish the changes, the content developer needs to use the Publish button in the Content Editor or the Full Editor. The other two options, A and C, are incorrect, as they do not describe the meaning of the Unpublished Revision status.

Describe the purpose and functionality of the Publish button)

Explanation
By using OGL, you can disable page elements that are not relevant or distracting for the user during a guide.
This feature is called Page Masking and it allows you to create a transparent overlay that covers the entire page except for the elements that you want to highlight or interact with. Page masking can improve the user experience and focus by hiding unnecessary or confusing elements. You can configure the page masking settings in the OGL editor, such as the opacity, color, and border of the overlay. You can also use the Exclude Elements option to select the elements that you want to exclude from the page masking. Page masking can be applied to any step type, not just hot-spots.

Explanation
Use Case content items are pre-built guides that are designed for specific business scenarios and applications.
They are stored in the Use Case library, which is a collection of use cases that are available for import into the OGL console. To make changes to Use Case content items, a user needs to first import the use case from the library into their OGL console. This will create a copy of the use case in the My Content section, where the user can edit, customize, and publish the guides as needed. The user cannot make changes to the use case in the Content Editor before importing it, as the Content Editor only allows editing of existing content items. The user also cannot make changes to the use case in the Use Case Details section of the Use Case library, as this section only provides information and preview of the use case,but does not allow editing.

Explanation
The Preview function on a guide file allows the OGL developer to preview the guide in a new browser tab as it would appear to end users in the production environment. The Preview function is useful for testing and validating the guide before publishing it to the end users. The Preview function can be accessed from the OGL console, by selecting the guide file and clicking the Preview button. The Preview function opens the guide in a new browser tab, where the OGL developer can see the guide steps, tips, and screen captures as they would be displayed to the end users. The Preview function also shows the OGL widget, where the OGL developer can see the guide name, description, and progress12.
The other statements are not true about the Preview function on a guide file. The Preview function does not allow the OGL developer to adjust the display settings of an individual guide before saving, as the display settings are configured in the OGL editor, not in the Preview function. The Preview function does not allow the OGL developer to edit or format the text content of a guide, as the text content is edited in the OGL editor, not in the Preview function. The Preview function is not a lab environment, but a simulation of the production environment12. References:

Explanation
The Full Editor is an advanced editor that allows for more editing and configuration of guides, including Display, Activation, and Advanced Settings1. One of the editing options in the Full Editor is to add steps and reselect elements for the guide. This can be done by selecting the Add Step icon and then choosing the UI element for the step2. You can also change the tip target by selecting Change Tip Target and editing the selector3. References:
