Explanation
A map is a type of component that enables users to view and manage data based on geographic locations. A map consists of a background map and spatial geometry objects that are sourced from data in a table or from a REST data source. Spatial geometry objects are shapes that represent real-world features on a map, such as points, lines, polygons, or heat maps. Three of the supported spatial geometry objects in Oracle APEX are:
Polygons: A polygon is a closed shape that consists of three or more vertices connected by straight line segments. A polygon can represent an area on a map, such as a country, a state, a city, or a building. A polygon can have different colors, patterns, or borders to indicate different attributes or categories of the data.
Heat map: A heat map is a type of visualization that uses color gradients to show the density or intensity of data values in a geographic area. A heat map can represent the distribution or variation of a numeric variable on a map, such as population, income, crime rate, or temperature.
Points: A point is a zero-dimensional shape that represents a single location on a map. A point can have different symbols, sizes, or colors to indicate different attributes or categories of the data. A point can also have a label or a tooltip to display additional information about the data.

Explanation
All of the options listed are different kinds of page components that you can create in APEX. A page component is an area of a page that serves as a container for content. Each page component contains a different type of content, such as HTML, a report, a form, a chart, a list, a breadcrumb, PL/SQL, a tree, a URL, or a calendar. You can create page components by using the Create Page Wizard, dragging and dropping from the Gallery pane in Page Designer, or using the context-sensitive menu in the Rendering tree in Page Designer.

Explanation
Collections are temporary tables that store session-specific data in memory. They can be used for various purposes in APEX applications. Some uses of collections are:
You insert, update, and delete collection information using PL/SQL API APEX_COLLECTION. This API provides several procedures and functions to manipulate collections and their members.
Use collections to temporarily capture one or more nonscalar values. For example, you can use collections to store the results of a query, the values of page items, or the selections of a report.
Collections can be accessed, manipulated, or processed during a user's specific session. For example, you can use collections to pass data between pages, perform calculations on collection members, or create reports based on collections.
Collections do not enable you to store rows and columns in the current session into database tables.
Collections are stored in memory and are not persistent across sessions.

Explanation
Custom Apps are specific to your workspace and are only available if your instance administrator has enabled them. You can install Sample Apps and Starter Apps directly from the Gallery or download them from GitHub. Sample Apps and Starter Apps are available with every Oracle APEX workspace.

Explanation
A faceted search is a type of component that enables users to filter information easily and intuitively by selecting the options in each facet. A faceted search consists of a faceted search region and a search results region. The faceted search region displays on the left and upper part of the screen and shows possible values and occurrence counts for each facet. The search results region displays on the right side of the screen and shows the data that matches the selected facet values. The search results region can display as either a classic report or a cards report. Three of the statements that are true about faceted search are:
After the end user changes a facet, the results, dependent facets, and occurrence counts refresh immediately. This feature provides instant feedback to the user and allows them to refine their search criteria without reloading the page.
The right side of the page features a Search Results region, which can display as a classic report or a cards report. A classic report displays data in a tabular format with columns and rows. A cards report displays data in a grid of cards with images and text.
The facets are displayed on the left and upper part of the screen. This layout provides a clear separation between the facets and the results and allows users to see and access all the facets without scrolling.
