NEW QUESTION # 30
The APEX engine uses which component as a key for tracking each user's session state?

• A. APEX_USER
• B. HTTP_USER
• C. LDAP_USER
• D. APP_USER

Answer: D

Explanation:
Explanation
APP_USER is a built-in substitution string in Oracle APEX that stores the user name of the current user session. The APEX engine uses APP_USER as one component of a key for tracking each user's session state.
As a user navigates from page to page, the APEX engine sets the value of APP_USER to identify the user. The APEX engine also uses APP_USER to perform security checks and conditional processing. You can reference APP_USER using different syntax depending on the context, such as SQL, PL/SQL, or static text.

NEW QUESTION # 31
Which statement is true about creating and using a report with form?

• A. Both the Create Application Wizard and Create Page Wizard support the creation of an interactive report or classic report and form combination.
• B. In the Create Application Wizard, you can select a data source (that is, Local Database, REST Enabled SQL Service, or REST Data Source).
• C. The Create Application Wizard doesn't support the creation of an interactive report and form combination.
• D. The Create Page Wizard doesn't support the creation of a classic report and formcombination

Answer: A

Explanation:
Explanation
You can create a report with form in Oracle APEX by using either the Create Application Wizard or the Create Page Wizard. The report can be either an interactive report or a classic report, and the form can be either a single row form or a multi row form. The report with form combination enables you to view and edit data from a table or a query in a single page. You can also customize the report and form attributes, such as the columns, regions, buttons, validations, processes, and so on.

NEW QUESTION # 32
There is a page with an interactive grid region based on this statement: SELECT EMPNO, ENAME, COMM from EMP; In the Interactive Grid attributes, under the Edit group, the Enabled switch is turned Off. Which are two of the actions that you must perform to make an employee's commission editable in the grid?

• A. Ensure that the "Primary Key" switch is turned "On" for the EMPNO column.
• B. Set EMPNO, ENAME to "Display Only".
• C. In the Interactive Grid attributes, select COMM for "Allowed Row Operations Column".
• D. In the Interactive Grid attributes, turn "On" the Enabled switch, under the Edit group.

Answer: A,D

Explanation:
Explanation
An interactive grid is a customizable report that allows end users to modify the data and layout of the report.
To make an employee's commission editable in the grid, you need to perform two actions:
In the Interactive Grid attributes, turn "On" the Enabled switch, under the Edit group. This enables editing for the entire interactive grid region and allows you to specify which columns are editable and which are not.
Ensure that the "Primary Key" switch is turned "On" for the EMPNO column. This identifies the EMPNO column as the primary key for the EMP table and allows APEX to perform DML operations on the table when end users edit the data in the grid. You do not need to set EMPNO or ENAME to
"Display Only" or select COMM for "Allowed Row Operations Column" to make an employee's commission editable in the grid. Verified References: [Managing Interactive Grids - Oracle Help Center], [Interactive Grid Attributes - Oracle Help Center]

NEW QUESTION # 33
When you run an application, the APEX engine relies on which two processes?

• A. Run Page
• B. Validate Page
• C. Accept page
• D. Show Page

Answer: C,D

Explanation:
Explanation
When you run an application, the APEX engine relies on two processes: Show Page and Accept Page. Show Page is responsible for rendering the page and sending it to the browser. Accept Page is responsible for processing the page when it is submitted by the browser. Run Page is not a process, but a command that can be used to run an application or a page from SQLWorkshop or Application Builder. Validate Page is not a process, but a step that occurs during page processing to check for any validations defined on the page

NEW QUESTION # 36
To create a Dynamic Action, you need to specify which three of the following options?

• A. Why the action is performed
• B. What action or actions are performed
• C. When the action occurs
• D. What elements are affected by the action

Answer: B,C,D

Explanation:
Explanation
To create a dynamic action, you need to specify at least three options: what action or actions are performed, when the action occurs, and what elements are affected by the action1. The action is the behavior that you want to happen when the event is triggered. You can choose from a list of predefined actions or create your own custom action using JavaScript code1. The event is the user interaction or condition that causes the dynamic action to fire. You can select an event from a list of available events based on the type of element you select1. The affected elements are the items, buttons, or regions that are affected by the action. You can select one or more elements by using jQuery selectors1. You do not need to specify why the action is performed, as this is not a required option for creating a dynamic action.

NEW QUESTION # 37
To highlight certain rows in the interactive report based on a condition, you must:

• A. Rows cannot be highlighted in an Interactive report
• B. Choose a condition in Format > Highlight
• C. Edit the rows in the report and select a color
• D. Provide a conditional SQL query

Answer: B

Explanation:
Explanation
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.

NEW QUESTION # 38
You can apply an authorization scheme for which three of the following components?

• A. A session
• B. Specific control such as region,item or button
• C. An entire application
• D. A page

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 # 39

Explanation:
Explanation
Using the App Builder component, you can perform the following tasks:
Edit pages in the page designer: You can use the Page Designer tool to modify the pages in your application using drag-and-drop operations, property editors, and code editors. You can also preview how your pages will look on different devices.
Install a sample app: You can use the Gallery option to install a sample app from a list of pre-built applications that demonstrate various features and best practices of Oracle APEX. You can also use the Packaged Apps option to install a packaged app from a list of ready-to-use applications that provide common functionality and solutions.
Create a new app: You can use the Create App option to create a new app from scratch or from an existing data source using the Create Application Wizard. You can also use the From a File option to create a new app from a file that contains data or metadata.
The other option is incorrect because:
Run SQL scripts and commands: You cannot use the App Builder component to run SQL scripts and commands. You can use the SQL Workshop component to run SQL scripts and commands using the SQL Commands or SQL Scripts tools.

NEW QUESTION # 40
Which two statements are true about a Progressive Web Application (PWA)?

• A. PWA features will be rendered even if the application is served in an unsecured environment.
• B. Enabling the PWA functionality in your APEX app adds a new navigation bar entry named Install App to your app.
• C. You can create a PWA only when creating a new application with the Create Application Wizard.
• D. To use the PWA feature, the Friendly URLS attribute in the Application Definition, Properties section must be turned Off.
• E. Enabling the PWA functionality optimizes page loading speed on a mobile device.

Answer: B,E

Explanation:
Explanation
A Progressive Web Application (PWA) is a web application that uses modern web technologies and best practices to provide a native app-like experience to users. Enabling the PWA functionality in your APEX app has the following benefits:
It optimizes page loading speed on a mobile device by caching static resources and using service workers to handle network requests.
It adds a new navigation bar entry named Install App to your app, which allows users to install the app on their device's home screen and access it offline.
It enhances the app's appearance and behavior by using a manifest file to specify the app's name, icon, theme color, orientation, and display mode.
The other options are incorrect because:
To use the PWA feature, the Friendly URLS attribute in the Application Definition, Properties section must be turned On. This attribute enables user-friendly URLs that are required for PWA functionality.
PWA features will not be rendered if the application is served in an unsecured environment. The application must use HTTPS protocol to enable PWA functionality.
You can create a PWA from an existing application or a new application with the Create Application Wizard. You just need to enable the PWA functionality in the User Interface section of the Application Definition.

Examine this code entered in Quick SQL:
emp_salary
name vc255
salary num
commission yn/check TRUE, FALSE
Which statement is true about the commission yn column?

• A. It will restrict acceptable values to Y or N.
• B. It will default to FALSE.
• C. It will restrict acceptable values to TRUE or FALSE.
• D. It will default to TRUE.

Answer: C

Explanation:
Explanation
The commission yn column will restrict acceptable values to TRUE or FALSE because of the /check modifier in the column name. This modifier adds a check constraint to the column based on the values specified after it.
The yn suffix indicates that the column is of type VARCHAR2(1). The other options are incorrect because they do not reflect the effect of the /check modifier or the yn suffix. Verified References: Using Quick SQLAbout Quick SQL Shorthand Syntax

Which authentication scheme type supports authentication with social networks and enterprise identity providers that support OpenID Connect or OAuth2 standards?

• A. SAML Sign-In
• B. HTTP Header Variable
• C. Open Door Credentials
• D. Social Sign-In

Answer: D

Explanation:
Explanation
An authentication scheme is a rule that determines if a user is authorized to access a specific component or feature of an application, such as a page, region, button, item, etc. An authentication scheme type defines how users are authenticated when they access an application. The authentication scheme type that supports authentication with social networks and enterprise identity providers that support OpenID Connect or OAuth2 standards is Social Sign-In. Social Sign-In supports authentication with Google, Facebook, and other social networks that support these standards. The other authentication scheme types do not support authentication with social networks or enterprise identity providers. They are:
HTTP Header Variable: Authenticate users externally by storing the username in a HTTP Header variable set by the web server.
SAML Sign-In: Delegates authentication to the Security Assertion Markup Language (SAML) Sign In authentication scheme.
Open Door Credentials: Enable anyone to access your application using a built-in login page that captures a user name. Verified References: [Understanding Preconfigured Authentication Schemes - Oracle Help Center], [Social Sign-In - Oracle Help Center]
