質問 # 57
Which two types of pages behave similarly in functionality?

  • A. Cards
  • B. Faceted Search
  • C. Map
  • D. Smart Filter

正解：B、D

解説：
Explanation
A Faceted Search and a Smart Filter are two types of pages that behave similarly in functionality. They both allow users to filter data based on multiple criteria and see the results in real time. They differ in the following aspects:
A Faceted Search uses facets to filter data. A facet is a set of filters based on a column or expression. A facet can be displayed as a list, a range slider, a star rating, or a chart.
A Smart Filter uses conditions to filter data. A condition is a logical expression that evaluates to true or false. A condition can be based on a column, an item, or a function.
The other options are incorrect because:
A Map is a type of region that displays spatial data on an interactive map. It allows users to zoom, pan, and select features on the map.
A Cards is a type of region that displays data in a grid of cards. Each card represents one row of data and can contain text, images, icons, or buttons.

質問 # 59
Which two statements are true about REST Data Source Synchronization?

  • A. If the local table is not in sync with the Data Profile, Data Synchronization doesn't work.
  • B. You cannot trigger Data Synchronization on a regular schedule using a scheduler job.
  • C. The local table can only be used for Data Synchronization but you cannot add indexes or change physical properties
  • D. To execute REST source synchronizations on schedule, the CREATE JOB privilege must be granted to the application's parsing schema.
  • E. If the local table is not in sync with the Data Profile, Data Synchronization continues to work for columns present in both the table and the Data Profile.

正解：D、E

解説：
Explanation
REST Data Source Synchronization is a feature that enables developers to automatically sync the contents of a local table with the data from an external REST service. To execute REST source synchronizations on schedule, the CREATE JOB privilege must be granted to the application's parsing schema, which allows APEX to create a DBMS_SCHEDULER job for each scheduled synchronization task. If the local table is not in sync with the Data Profile, which defines the columns and data types of the REST service response, Data Synchronization continues to work for columns present in both the table and the Data Profile (other columns are ignored). However, APEX generates SQL DDL statements to sync table columns back to the Data Profile, which can be added to the application as supporting objects.

  • B. Create a report as a new page in an application
  • C. Create a report region on a page in an application
  • D. Create a report from Object Browser

正解：A、B、C

解説：
Explanation
You can create a report in any of these three methods:
Create a report as a new page in an application by using the Create Page Wizard. This wizard guides you through the steps of selecting a page type, defining attributes, selecting a source (such as SQL query or table), and adding items or buttons.
Create a report when you create a new database application by using the Create Application Wizard.
This wizard allows you to generate one or more reports based on existing tables or views in your schema. You can also create a report and form on the same table or view.
Create a report region on a page in an application by using the Page Designer. This tool allows you to drag and drop a region type (such as Classic Report, Interactive Report, or Interactive Grid) onto the page and define its attributes and source.
The other option is incorrect because:
You cannot create a report from Object Browser. Object Browser is a tool that allows you to view and manage the database objects in your schema, such as tables, views, indexes, etc. You can only run SQL queries or scripts from this tool, not create reports.

質問 # 67
Which three of the following statements are TRUE about Data Synchronization?

  • A. Helps in Providing efficient reporting on large data sets coming from a REST service
  • B. Data Synchronization enables developers to automatically sync the contents of a local table with the data from a REST service.
  • C. You must trigger Data Synchronization manually
  • D. APEX can create the local table based on the visible columns in the REST Data Source Data Profile.

正解：A、B、D

解説：
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.
