- A. Create new application roles
- B. Create Authorization schemes
- C. Add Users
- D. Assign roles to users
Answer: C,D
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 # 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. PL/SQL procedure
- B. Processing
- C. Conditional SQL
- D. Dynamic Actions
Answer: D
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.

Displaying form fields with different alignments. Developers can use template options to change the alignment of form fields and labels, such as left-aligned, right-aligned, or top-aligned.
NEW QUESTION # 29
The APEX engine uses which component as a key for tracking each user's session state?
- A. APP_USER
- B. LDAP_USER
- C. APEX_USER
- D. HTTP_USER
Answer: A
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.

Explanation:
Explanation
Collections are temporary tables that store session-specific data in memory. They can be used for various purposes in APEX applications. Some uses of collections are:
You insert, update, and delete collection information using PL/SQL API APEX_COLLECTION. This API provides several procedures and functions to manipulate collections and their members.
Use collections to temporarily capture one or more nonscalar values. For example, you can use collections to store the results of a query, the values of page items, or the selections of a report.
Collections can be accessed, manipulated, or processed during a user's specific session. For example, you can use collections to pass data between pages, perform calculations on collection members, or create reports based on collections.
Collections do not enable you to store rows and columns in the current session into database tables.
Collections are stored in memory and are not persistent across sessions.
NEW QUESTION # 33
There is a validation of type Item is numeric on the P1_SALARY item. When the page is submitted, this or message is displayed both in the notification and below the item: What will cause the validation error to appear only in the Notification area?
- A. Setting Display Location to Inline in Notification
- B. Removing P1_SALARY from the validation Associated Item
- C. Setting the value Required to Yes on P1_SALARY
Answer: B
Explanation:
Explanation
A validation is a rule that checks the data entered by end users before processing it. A validation of type Item is numeric checks if a page item value is a valid number. When the page is submitted, if the validation fails, an error message is displayed both in the notification area (atthe top of the page) and below the item (next to the item label). To cause the validation error to appear only in the notification area, you need to remove P1_SALARY from the validation Associated Item attribute. The Associated Item attribute specifies which page item is associated with the validation and where to display the error message if the validation fails.
Setting the value Required to Yes on P1_SALARY or setting Display Location to Inline in Notification will not affect the validation error display. Verified References: [Creating Validations - Oracle Help Center],

NEW QUESTION # 38
Consider a customers report. A customer name is clicked in the report to display the Customer Details form. When the items in the form dialog are updated and the user clicks Apply Changes, the page process is executed and the items from the page are used to update and commit the underlying table in the Oracle Database. What are the two types of events that occurred in this scenario?
- A. Page Rendering
- B. Page Refresh
- C. Page Processing
- D. Page Validation
Answer: C,D
Explanation:
Explanation
When the customer name is clicked in the report, the Customer Details form dialog page is displayed. This is a page rendering event, which means the page is generated and sent to the browser. When the items in the form dialog are updated and the user clicks Apply Changes, the page process is executed and the items from the page are used to update and commit the underlying table in the Oracle Database. This is a page processing event, which means the page is submitted to the server and processed by APEX. Page validation is also a part of page processing, but it is not a separate event. Page refresh is not an event, but an action that can be triggered by a dynamic action or a process
