NEW QUESTION # 48
What three are the result of the following QuickSQL shorthand notation do?
departments /insert 4
name /nn
location
country
- A. Inserts 4 rows of random data into the departments table
- B. Create the departments table with 3 columns
- C. Create the departments table with 4 columns
- D. Creates an id column as a primary key
Answer: A,C,D
Explanation:
Explanation
The QuickSQL shorthand notation departments /insert 4 name /nn location country will do the following:
Create the departments table with 4 columns: The first word in the notation is the table name, followed by a slash and the number of rows to insert. The subsequent words are the column names, separated by spaces. QuickSQL will generate a SQL script to create the table with the specified columns and data types.
Creates an id column as a primary key: QuickSQL will automatically add an id column as a primary key to the table, unless the /no_pk modifier is used. The idcolumn will be of type NUMBER and will use an identity constraint to generate unique values.
Inserts 4 rows of random data into the departments table: QuickSQL will use the /insert modifier to insert random data into the table, based on the column names and data types. The number after the modifier indicates how many rows to insert.
The other option is incorrect because:
Create the departments table with 3 columns: This is not what the notation will do. The notation will create the table with 4 columns, not 3.

- A. Create a report when you create a new database application
- B. Create a report from Object Browser
- C. Create a report region on a page in an application
- D. Create a report as a new page in an application
Answer: A,C,D
Explanation:
Explanation
You can create a report in any of these three methods:
Create a report as a new page in an application by using the Create Page Wizard. This wizard guides you through the steps of selecting a page type, defining attributes, selecting a source (such as SQL query or table), and adding items or buttons.
Create a report when you create a new database application by using the Create Application Wizard.
This wizard allows you to generate one or more reports based on existing tables or views in your schema. You can also create a report and form on the same table or view.
Create a report region on a page in an application by using the Page Designer. This tool allows you to drag and drop a region type (such as Classic Report, Interactive Report, or Interactive Grid) onto the page and define its attributes and source.
The other option is incorrect because:
You cannot create a report from Object Browser. Object Browser is a tool that allows you to view and manage the database objects in your schema, such as tables, views, indexes, etc. You can only run SQL queries or scripts from this tool, not create reports.

NEW QUESTION # 54
You can apply an authorization scheme for which three of the following components?
- A. A session
- B. A page
- C. An entire application
- D. Specific control such as region,item or button
Answer: B,C,D
Explanation:
Explanation
You can apply an authorization scheme for the following components in APEX:
A specific control such as a region, item, or button. You can select an authorization scheme from the Authorization Scheme list on the attributes page of the control. This will control the rendering and processing of the control based on the user privileges12.
A page. You can select an authorization scheme from the Authorization Scheme list on the Security page of the page definition. This will control the access to the page based on the user privileges12.
An entire application. You can select an authorization scheme from the Authorization Scheme list on the Security Attributes page of the application definition. This will control the access to the entire application based on the user privileges12.
You cannot apply an authorization scheme for a session, as a session is not a component in APEX. A session is a stateful connection between a browser and the APEX engine that persists across multiple requests and responses3. You can control session security by using session state protection, session expiration, and session isolation4.
NEW QUESTION # 55
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. Interactive Report
- B. Side by Side Master Detail
- C. Cards
- D. Stacked Master Detail
Answer: D
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.
NEW QUESTION # 56
Select the three types of Card Layout you can create in APEX.
- A. Horizontal(Row)
- B. Float
- C. Vertical(Column)
- D. Grid
Answer: A,B,D
Explanation:
Explanation
You can create two types of card layout in APEX: Float and Grid. Float layout displays cards in a single row that wraps to the next row when the available space is filled. Grid layout displays cards in a fixed number of columns that can be responsive to the screen size1. Vertical and Horizontal are not valid card layout types in APEX.
NEW QUESTION # 57
You created a custom theme for an application. Examine these requirements: 1. The theme must be utilized by another application in the same workspace. 2. The master theme may still require changes. Which solution guarantees that any changes to the master theme are reflected in the copied theme?
- A. Verifying the theme subscription
- B. Copying the changes made in the master theme to the copied theme
- C. Refreshing the templates
- D. Subscribing the copied theme to the master theme and refreshing the theme
Answer: D
Explanation:
Explanation
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.

NEW QUESTION # 58
Which statement is true about importing an APEX application?
- A. You cannot import an APEX application exported from a latest APEX version to an old APEX version.
- B. The import process does not import the supporting objects defined during the export.
- C. You cannot change the application ID during the import process.
Answer: A
Explanation:
Explanation
As a general rule, you cannot import an application created in a newer release of APEX into an earlier version.
This is because the newer release may have features or attributes that are not supported or recognized by the older version. For example, you cannot import an application created in APEX 21.2 into APEX 19.2.
However, you can import an application created in an older release into a newer one, as long as the application is compatible with the newer release. For example, you can import an application created in APEX 18.2 into APEX 21.2, but you may need to upgrade or modify some components to use the latest features.

- C. You can create only two workspaces in an APEX Service(APEX Application Development)instance.
- D. A workspace enables multiple users to work within the same Oracle APEX installation.
- E. A workspace can be associated with only one schema.
Answer: A,D
Explanation:
Explanation
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.

When you create an Access Control Page, which three of the following Access Roles get created?
- A. Contributor
- B. Developer
- C. Administrator
- D. Reader
Answer: A,C,D
Explanation:
Explanation
When you create an Access Control Page using the Create Page Wizard, three of the following Access Roles get created: Reader, Administrator, and Contributor.
