• B. Label Column
• C. Name
• D. Data Source
• E. Value Column

Answer: A

Explanation:
Explanation
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.

NEW QUESTION # 45
Which two types of pages behave similarly in functionality?

• A. Faceted Search
• B. Cards
• C. Map
• D. Smart Filter

Answer: A,D

Explanation:
Explanation
A Faceted Search and a Smart Filter are two types of pages that behave similarly in functionality. They both allow users to filter data based on multiple criteria and see the results in real time. They differ in the following aspects:
A Faceted Search uses facets to filter data. A facet is a set of filters based on a column or expression. A facet can be displayed as a list, a range slider, a star rating, or a chart.
A Smart Filter uses conditions to filter data. A condition is a logical expression that evaluates to true or false. A condition can be based on a column, an item, or a function.
The other options are incorrect because:
A Map is a type of region that displays spatial data on an interactive map. It allows users to zoom, pan, and select features on the map.
A Cards is a type of region that displays data in a grid of cards. Each card represents one row of data and can contain text, images, icons, or buttons.

NEW QUESTION # 55
Select the two advantages of using One-click Remote Deployment.

• A. Simplify the process of deploying an application
• B. You need to access your production environment to import the app directly.
• C. Deploy the app, and explicitly install the supporting objects in one-click.
• D. Directly deploy your app definition along with the objects from the source system to the target system

Answer: C,D

Explanation:
Explanation
One-click remote application deployment is a feature in Oracle APEX that simplifies the process of deploying an application from one APEX instance to another using REST Enabled SQL references. REST Enabled SQL references are shared components that work with an Oracle REST Data Services (ORDS) REST Enabled SQL Service. One-click remote application deployment can authenticate through first party authentication (Basic Authentication), Schema Authentication (database username and password), or OAuth 2 Client Credentials.
Two of the advantages of using one-click remote application deployment are:
Deploy the app, and explicitly install the supporting objects in one-click. This advantage allows you to package the app definition along with the database objects, images, and seed data necessary for your application to run correctly using the Supporting Objects functionality in APEX. You can then export and deploy this app and install the supporting objects in one-click without having to manually create or copy the database objects in the target system.
Directly deploy your app definition along with the objects from the source system to the target system.
This advantage allows you to avoid the intermediate step of exporting the app and its objects from the source system into files and then importing them into the target system. You can directly deploy your app and its objects from within your development environment to the remote production environment without having to access your production environment.

NEW QUESTION # 56
Consider a page in an APEX app where the Departments names with location is displayed on the left. Selecting a Department on the left will render details of the employees corresponding to that department on the right. Which kind of report/form is this?

• A. Cards
• B. Stacked Master Detail
• C. Interactive Report
• D. Side by Side Master Detail

Answer: B

Explanation:
Explanation
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.

The form page includes page items P21 PRODUCT NAME and P21_UNIT_PRICE.
P21_UNIT_PRICE is currently displayed below P21_PRODUCT_NAME.
Now, you need to reposition the items and display P21 UNIT_PRICE next to P21_PRODUCT_NAME.
Which two statements are true?

• A. In Page Designer, right-click P21_UNIT_PRICE and select Start New Row.
• B. In Page Designer, use the Middle Pane, click P21 UNIT PRICE and drag the item until it is directly next to P21 PRODUCT_NAME.
• C. In Page Designer, select P21_PRODUCT_NAME and then in the Property Editor, under Layout set Start New Row to Yes.
• D. In Page Designer, select P21_UNIT_PRICE and then in the Property Editor, under Layout set Start New Row to Yes.

Answer: B,D

Explanation:
Explanation
To reposition the page items and display P21_UNIT_PRICE next to P21_PRODUCT_NAME, you can use either of these methods:
In Page Designer, use the Middle Pane, click P21_UNIT_PRICE and drag the item until it is directly next to P21_PRODUCT_NAME. This method allows you to visually arrange the items on the page layout.
In Page Designer, select P21_UNIT_PRICE and then in the Property Editor, under Layout set Start New Row to Yes. This method changes the attribute of the item to start a new row in the grid layout. The other options, A and D, are incorrect because they would not achieve the desired result. Setting Start New Row to Yes for P21_PRODUCT_NAME would move it to a new row, not next to P21_UNIT_PRICE. Right-clicking P21_UNIT_PRICE and selecting Start New Row would not change the attribute of the item, but only move it to a new position in the Layout tab.
