NEW QUESTION # 11
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.

NEW QUESTION # 16
Which two are valid evaluation points for Authorization Schemes?
- A. Once per user
- B. Once per page view
- C. Once per session
- D. Never
Answer: B,D
Explanation:
Explanation
An authorization 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 authorization scheme can be evaluated at different points in time depending on its evaluation point attribute. The valid evaluation points for authorization schemes are:
Never: The authorization scheme is never evaluated and always returns false.
Once per session: The authorization scheme is evaluated only once per user session and caches the result for subsequent requests.
Once per page view: The authorization scheme is evaluated once per page view and caches the result for subsequent requests within the same page view.
On each new page view or partial page refresh: The authorization scheme is evaluated on each new page view or partial page refresh (for example, when using dynamic actions) and caches the result until the next page view or partial page refresh.
On each request (not cached): The authorization scheme is evaluated on each request and does not cache the result. Once per user and Once per page load are not valid evaluation points for authorization schemes.

NEW QUESTION # 17
Which two are true about Oracle APEX?
- A. Requires developers to be proficient in Java, Python and other programming languages.
- B. Is declarative. It requires no code generation.
- C. Requires no additional client software. A web browser is the app development IDE.
- D. Performs the data processing in a middle-tier server
Answer: B,C
Explanation:
Explanation
Oracle APEX is a low-code development platform that enables you to build database-centric web applications using only a web browser. Oracle APEX has the following features:
Requires no additional client software. A web browser is the app development IDE: You can use any modern web browser to access the Oracle APEX development environment and build your applications.
You do not need to install or configure any additional software or tools on your client machine.
Is declarative. It requires no code generation: You can use declarative tools, visual editors, drag-and-drop components, and pre-built templates to define your application logic, user interface, security, and integration features. You do not need to write or generate any code for your applications.
The other options are incorrect because:
Performs the data processing in a middle-tier server: Oracle APEX performs the data processing in the database server. It uses SQL and PL/SQL to access and manipulate the data stored in the database. It does not rely on any middle-tier server or framework for data processing.
Requires developers to be proficient in Java, Python and other programming languages: Oracle APEX does not require developers to be proficient in Java, Python or other programming languages. It uses SQL and PL/SQL as the primarylanguages for data processing. It also supports HTML, CSS, JavaScript, and jQuery for user interface development.

NEW QUESTION # 18
You use the Create Page Wizard to create a faceted search page on the EMP table. What is the default report type generated for this page?
- A. Interactive Report
- B. Column Toggle Report
- C. Interactive Grid
- D. Classic Report
Answer: D
Explanation:
Explanation
When you use the Create Page Wizard to create a faceted search page on any table or SQL query, such as EMP table, APEX generates a classic report region as default report type for this page. A classic report region displays data from a SQL query or PL/SQL function returning a SQL query in tabular format. A faceted search page also contains a region of Faceted Search type, which holds one or more facets that allow end users to filter data by applying one or more facets.

NEW QUESTION # 19
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 Validation
- D. Page Processing
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
NEW QUESTION # 20
