Oracle APEX Developer Professional Sample Questions (Q86-Q91):

NEW QUESTION # 86
What are the three types of Master Detail Form you can create in APEX?

A. One Below the other
B. Two Page Drill Down
C. Stacked
D. Side by Side

Answer: B,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 # 87
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. Processing
B. Conditional SQL
C. PL/SQL procedure
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.

NEW QUESTION # 88
Choose the three Form types that you can create using the Create Page wizard.

A. Interactive Grid
B. Interactive Report
C. Master Detail
D. Form

Answer: A,C,D

Explanation:
Explanation
The Create Page wizard supports three form types that you can create: Interactive Grid, Form, and Master Detail4. An interactive grid is a report that allows users to view and edit data in a tabular format. A form is a page that enables users to update a single row in a database table or view. A master detail is a page that reflects a one-to-many relationship between two tables or views4. 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 # 89
When you click a Customer Name in the Customers report, the Customer Details form dialog page is displayed. What are the events that occur in this scenario?

A. Page Rendering
B. Page compilation
C. Page Processing
D. Page rendering and processing

Answer: D

Explanation:
Explanation
When you click a Customer Name in the Customers report, the Customer Details form dialog page is displayed. This involves two events: page rendering and page processing. Page rendering is the event that occurs when APEX generates and sends the page to the browser. Page processing is the event that occurs when APEX receives and processes the page from the browser. In this scenario, both events happen because the Customer Details form dialog page is a modal dialog that uses AJAX to communicate with the server without reloading the entire page. Page compilation is not an event, but an action that occurs when APEX compiles an application or a page before running it.

NEW QUESTION # 90
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. Browser Events
B. All of them
C. Component Events
D. Framework Events
E. Custom Events

Answer: B

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.
