To create a chart in Oracle APEX, you need to provide some required fields that define the data source and appearance of the chart. You can use either the Create Page Wizard or Page Designer to create a chart. The required fields for creating a chart are:

• Data Source: This field specifies the SQL query that returns the data for the chart. The query must include at least one column for the label and one column for the value of each data point. You can also include additional columns for grouping, color, or tooltip information.
• Value Column: This field specifies the column from the data source query that contains the numeric values for the chart. The values are used to plot the data points on the chart and determine the size of each data point or segment.
• Name: This field specifies the name of the chart region. The name is used to identify the region in Page Designer and other components, such as dynamic actions or processes.
• Label Column: This field specifies the column from the data source query that contains the labels for the chart. The labels are used to display the name of each data point or segment on the chart or in the legend.

A theme is a collection of templates and stylesheets that define the layout and appearance of an application. You can create a custom theme for an application by using the Create Theme Wizard or by copying an existing theme. If you want to use a custom theme for anotherapplication in the same workspace, you can copy the theme to that application by using the Copy Theme option in Shared Components. However, if the master theme (the original theme) may still require changes, you need to subscribe the copied theme to the master theme and refresh the theme whenever there are changes in the master theme. This solution guarantees that any changes to the master theme are reflected in the copied theme by using a synchronization process that updates templates and stylesheets based on their subscription status.

To highlight certain rows in the interactive report based on a condition, you must choose a condition in Format > Highlight. This option allows you to apply a conditional formatting rule to the report, which changes the appearance of the rows that match the condition. You can specify the condition type, expression, column, operator, and value. You can also choose the highlighting style, such as background color, text color, or icon.

The other options are incorrect because:

• Provide a conditional SQL query: This option will not highlight certain rows in the interactive report based on a condition. It will filter the data in the report by applying a WHERE clause to the SQL query that defines the report source.
• Edit the rows in the report and select a color: This option will not highlight certain rows in the interactive report based on a condition. It will modify the data in the report by using inline editing or modal dialog editing. You cannot select a color for the rows in this option.
• Rows cannot be highlighted in an Interactive report: This option is false. Rows can be highlighted in an Interactive Report by using the Format > Highlight option.

Smart Filters is a component that allows end users to filter data by typing keywords in a single search field. Some of the statements that are true about creating and customizing Smart Filters pages are:

• If you create a Smart Filters page based on a table, the filters are auto discovered using the Data Dictionary Cache. You can also manually add or remove filters as needed.
• The suggestion chip count is only displayed for filters that support counts, such as LOV-based filter types. For other filter types, such as Input or Range, the count is not displayed. The search results report cannot be displayed as an interactive report or an interactive grid. The supported report types are Classic Report, Cards, Map, or Calendar.

A workspace is a logical work area that enables multiple users to work within the same Oracle APEX installation while keeping their objects, data, and applications private. Creating and managing an APEX workspace involves the following statements:

• During workspace creation, you can associate the workspace with an existing database schema or create a new schema for the workspace. A schema is a collection of database objects such as tables, views, indexes, etc. that belong to a user.
• A workspace enables multiple users to work within the same Oracle APEX installation. Each user can have a different role and privilege in the workspace, such as workspace administrator, developer, or end user.
• A workspace can be associated with one or more schemas. You can add or remove schemas from a workspace after it is created.
• You can create as many workspaces as you need in an APEX Service (APEX Application Development) instance. There is no limit on the number of workspaces per instance.

A stacked master detail is a form type that displays two editable interactive grids based on two related tables or views on the same page. Users select a row in the master grid to update the detail grid6. In this scenario, the departments names with location on the left is the master grid and the employees details on the right is the detail grid. A cards report is not a form type, but a report type that displays data in cards with an image and text7. A side by side master detail is a form type that displays two editable interactive grids based on two related tables or views side by side on the same page. Users select multiple rows in the master grid to update multiple detail grids6. An interactive report is not a form type, but a report type that allows users to customize the report layout and filter data interactively5.

A list of values (LOV) is a definition that provides a set of display values and return values for a page item or a report column. A LOV can be created at the application level as a shared component or at the page level as a local component. There are three types of LOVs that you can create on a page:

• Static LOV: A static LOV is based on a fixed list of display values and return values that you specify when you create the LOV. A static LOV does not change unless you edit it manually.
• Cascading LOV: A cascading LOV is based on another parent LOV that determines the values of the child LOV. A cascading LOV changes dynamically depending on the selection made in the parent LOV.
• Dynamic LOV: A dynamic LOV is based on a SQL query that returns display values and return values from the database. A dynamic LOV changes dynamically depending on the data in the database.

A Link Column is a special column type that you can define for an interactive report to create a link to another page, URL, or custom target. A Link Column is always displayed as the first column in the report, regardless of the order of the columns in the query. A Link Column cannot be sorted, hidden, or moved by an end user using the Actions menu or the column header. However, a developer can change the position and visibility of a Link Column by editing the report attributes in Page Designer. 

A smart filters page is a type of component that features a single search field at the top of the page and a search results report (classic report, cards, map, or calendar) at the bottom. A smart filters page behaves similarly to faceted search, but it features a more space efficient layout. Two of the features of a smart filters page are:

• Consists of a single search field with filters at the top of the page and a report at the bottom. This feature provides a simple and compact user interface that allows users to enter text in the search field and see suggested filters based on their input. Users can also see and modify applied filters at any time.
• Each filter displays as a suggestion chip with a single count of how often the specific suggestion value occurs. This feature provides useful information to users about how many records match each filter value. Users can also choose between different types of suggestions, such as dynamic, static, or SQL query.

Session state management is a feature that enables developers to store and retrieve values for a user as the user navigates between different application pages. A session is a logical construct that establishes persistence (or stateful behavior) across page views. Each session is assigned a unique identifier (or session ID). The statement that is true about session state management in Oracle APEX is:

• APEX Sessions are logically and physically distinct from Oracle database sessions used to service page requests. APEX Sessions are stored in memory within an Application Express engine process while Oracle database sessions are stored in memory within an Oracle database process. The other statements are false because:
• A user can run multiple instances of an application simultaneously in different browser programs by using different session IDs.
• Multiple number of sessions can exist in the database at the same time for different users or applications. Verified References: [Understanding Session State Management - Oracle Help Center], [What Is a Session? - Oracle Help Center]
