Question 12
Which two statements are true about the Create Application Wizard?
Correct Answer: A,B
Explanation The Create Application Wizard is a tool that allows developers to create a new application by following a series of steps. Some of the actions that you can perform using the Create Application Wizard are: Reorder application pages. You can use the Reorder Pages option in the Pages step to change the order of the pages in your application by dragging and dropping them. Add or delete application pages. You can use the Add Page or Delete Page options in the Pages step to add new pages or delete existing pages from your application. You can also use the Create Page Wizard to create additional pages after creating the application. You cannot upload JavaScript or CSS files required for an application or change the application authorization using the Create Application Wizard. You can use other features in App Builder to perform these actions, such as Shared Components > User Interface > Files and Shared Components > Security > Authentication Schemes.

Question 13
Which statement is true about creating and using a report with form?
Correct Answer: A
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.

Question 14
Which three of the following statements are TRUE about Data Synchronization?
Correct Answer: A,B,C
Explanation Data Synchronization enables developers to automatically sync the contents of a local table with the data from a REST service. APEX invokes the REST service defined in the REST Data Source, downloads all data and synchronizes it to a local table6. Data Synchronization has several benefits, such as: APEX can create the local table based on the visible columns in the REST Data Source Data Profile. Since the table is physically available in the database schema, developers can add indexes, change physical properties, or even add more columns6. Data Synchronization helps in providing efficient reporting on large data sets coming from a REST service. Some REST services can return large amounts of result data that include pagination. If a reporting requirement needs larger data sets, this would lead to multiple HTTP requests and poorer response times. Also, no indexes or other database features can be used to speed up reporting queries. In this case, synchronizing the remote data to a local table and having the reports working on local tables can improve performance and user experience6. Data Synchronization can also collect data from REST services for consumption by PL/SQL packages or other logic. If data from the REST service is replicated to local tables, developers will be able to perform all sorts of processing and also generate different types of reports6. You do not have to trigger Data Synchronization manually, as you can also schedule it to run periodically using a DBMS_SCHEDULER expression6.
Question 15
Which two are prerequisites to use the REST-enabled SQL feature in Oracle APEX?
Correct Answer: A,B
Explanation The REST-enabled SQL feature in Oracle APEX allows developers to execute SQL statements and PL/SQL blocks on a remote Oracle Database by using REST services. The prerequisites to use this feature are: On the remote Oracle Database, install ORDS 19.x or later. REST enable the schema in the remote Oracle Database using ORDS.ENABLE_SCHEMA. Create a REST Data Source with REST Enabled SQL as the REST Data Source Type in Oracle APEX. Create an Authorization Scheme based on the REST Data Source in Oracle APEX. You do not need to create a database link to the remote Oracle Database or install Oracle APEX in the remote Oracle Database to use this feature.
