NEW QUESTION # 17
In APEX, you can choose which three of the following Authentication methods?
- A. No Authentication
- B. Authorization Scheme
- C. Built-in Authentication Scheme
- D. Custom Authentication Scheme
Answer: A,C,D
Explanation:
Explanation
In Oracle APEX, you can choose from different authentication methods to establish a user's identity and control access to your application. Authentication may require a user to provide some type of credentials, such as a user name and password, or could involve the use of digital certificates or a secure key. Three of the authentication methods that you can choose in Oracle APEX are:
Custom Authentication Scheme: This method allows you to create your own authentication logic using PL/SQL code or an external web service. You can also customize the login page and session management for your application.
No Authentication (using DAD): This method adopts the current database user as the authenticated user.
This approach can be used in combination with a mod_plsql Database Access Descriptor (DAD) configuration that uses basic authentication to set the database session user.
Built-in Authentication Scheme: This method allows you to use one of the preconfigured authentication schemes that ship with Oracle APEX, such as Open Door Credentials, LDAP Directory, Social Sign-In, and so on.

- A. Add Users
- B. Create Authorization schemes
- C. Assign roles to users
- D. Create new application roles
Answer: A,C
Explanation:
Explanation
The Access Control feature pages are a set of pages that allow developers to implement role-based access control for an application. The Access Control feature pages consist of four pages: Administration, Users, Roles, and Role Assignments. The Administration page allows administrators to perform various tasks related to managing users and roles, such as:
Add Users: Administrators can add new users to the application by entering their username, email address, password, status, etc.
Assign roles to users: Administrators can assign one or more roles to users by selecting them from a list of available roles.
Edit Users: Administrators can edit user details such as username, email address, password, status, etc.
Delete Users: Administrators can delete users from the application by selecting them from a list of existing users.
Lock/Unlock Users: Administrators can lock or unlock users by changing their status from active to locked or vice versa. You cannot create authorization schemes or create new application roles using the Administration page. You can create authorization schemes by using Shared Components > Security > Authorization Schemes. You can create new application roles by using Shared Components > Security > Access Control > Roles.

NEW QUESTION # 22
Which three of the following are use cases of Automations?
- A. Deleting a database record based on an end user's request
- B. Approving specific requests
- C. Sending email alerts at a particular time of the week
- D. Monitoring log tables and raising an alert when there is an issue
Answer: B,C,D
Explanation:
Explanation
Automations are a sequential set of PL/SQL actions that are triggered by query results. They are used to monitor data and then perform the appropriate action2. Some use cases of automations are:
Monitoring log tables and raising an alert when there is an issue. For example, an automation can query a log table for any errors and send an email notification to the administrator if any errors are found2.
Approving specific requests. For example, an automation can query a table for any pending requests and approve them automatically based on some criteria2.
Sending email alerts at a particular time of the week. For example, an automation can query a table for any overdue tasks and send a reminder email to the assignees every Monday2.
Deleting a database record based on an end user's request is not a use case of automations, as it does not involve querying data and triggering actions based on the query results. This can be achieved by using a PL/SQL process or a dynamic action on the page where the user requests the deletion34.
NEW QUESTION # 23
What are the three types of Master Detail Form you can create in APEX?
- A. Side by Side
- B. One Below the other
- C. Stacked
- D. Two Page Drill Down
Answer: A,C,D
Explanation:
Explanation
A master detail form is a type of form that enables users to query, insert, update, and delete values from two related tables or views. A master detail form reflects a one-to-many relationship between tables in a database.
Typically, a master detail form displays a master row and multiple detail rows. In APEX, you can create three types of master detail forms using the Create Page Wizard or the Create Application Wizard:
Stacked: A stacked master detail form contains a single page with editable interactive grids based on two related tables or views. Users select a row in the master grid to update the detail grid. Developers can create a stacked master detail with either the Create Application Wizard or the Create Page Wizard.
Side by Side: A side by side master detail form contains a single page with two editable interactive grids based on two related tables or views. Users can see and edit both the master and detail grids at the same time. Developers can create a side by side master detail with either the Create Application Wizard or the Create Page Wizard.
Two Page Drill Down: A two page drill down master detail form contains two pages based on two related tables or views. The first page is a non-editable interactive grid for the master table. Users click the Edit icon on the first page to edit details on the second page. The second page includes both a standard form for the master and an editable interactive grid for the detail. Developers can create a two page drill down master detail with only the Create Page Wizard.
NEW QUESTION # 24
Select the two advantages of using One-click Remote Deployment.
- A. Deploy the app, and explicitly install the supporting objects in one-click.
- B. Simplify the process of deploying an application
- C. You need to access your production environment to import the app directly.
- D. Directly deploy your app definition along with the objects from the source system to the target system
Answer: A,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 # 25
Choose from the following the different kinds of page components you can create in APEX.
- A. Smart Filters
- B. All of them
- C. Search Page
- D. Interactive Grid
- E. Faceted Search
Answer: B
Explanation:
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.
NEW QUESTION # 26
When you create a Dynamic Action, you specify the event that causes the dynamic action to fire.
Choose the categories these events are classified into.
- A. All of them
- B. Browser Events
- C. Custom Events
- D. Component Events
- E. Framework Events
Answer: A
Explanation:
Explanation
The events that cause the dynamic action to fire are classified into five categories: Browser Events, Component Events, Custom Events, Framework Events, and jQuery Events1. Browser events are triggered by user interactions with the browser window, such as resize, scroll, or unload. Component events are triggered by user interactions with specific APEX components, such as interactive grids, interactive reports, or trees.
Custom events are user-defined events that can be triggered by other dynamic actions or JavaScript code.
Framework events are triggered by APEX framework actions, such as page load, page submit, or dialog close. jQuery events are triggered by user interactions with jQuery UI widgets, such as accordion, tabs, or date picker1.
NEW QUESTION # 27
In an Employee form, the 'Commission' and 'Hire Date' fields are enabled only if the Job is
'Salesman'. This can be achieved by which feature of APEX?
- A. Dynamic Actions
- B. Conditional SQL
- C. Processing
- D. PL/SQL procedure
Answer: A
Explanation:
Explanation
In an Employee form, the 'Commission' and 'Hire Date' fields are enabled only if the Job is 'Salesman'. This can be achieved by using Dynamic Actions in APEX. Dynamic Actions are declarative components that define client-side behavior without writing JavaScript code. You can create Dynamic Actions on items, buttons, or regions of a page by specifying an event, a condition, an action, and other properties. In this scenario, you can create a Dynamic Action on Job item with Change as event, Execute JavaScript Code as action, and use jQuery to enable or disable Commission and Hire Date fields based on Job value. Processing, Conditional SQL, and PL/SQL procedure are not features of APEX that can achieve this requirement without writing JavaScript code.
NEW QUESTION # 28
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
NEW QUESTION # 29
Select two features of a Smart Filters Page.
- A. Each filter represents the text entered by the end user in the search field
- B. Consists of a single search field with filters at the top of the page and a report at the bottom
- C. Each filter displays as a suggestion chip with a single count of how often the specific suggestion value occurs.
- D. Consists of filters at the left side and report on the right side of the page
Answer: B,C
Explanation:
Explanation
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.
