Final answer:
Portal preferences personalize the user experience but do not define the zones within a portal, which is handled by layout or structure settings.
Step-by-step explanation:
Portal preferences are used to define certain user interface aspects of a web portal, such as default language, regional settings, and themes. However, the statement that portal preferences are used to define the zones that appear in a portal is false.
Zones or areas within a portal that hold content or widgets are typically defined by the portal's layout or structure settings, not by user preferences. Portal preferences are more about personalizing the user experience rather than structuring the portal's content zones.
True, portal preferences are used to define the zones that appear in a portal. Preferences allow users to customize their experience and control which zones are displayed on their portal homepage. This helps users personalize their portal based on their specific needs and interests.
Therefore, the statement is 1) True.
