Oracle APEX Developer Professional Sample Questions (Q64-Q69):

NEW QUESTION # 64
You have defined a REST Data Source with ORDS as the REST Data Source Type. This REST Data Source is based on an AutoREST-enabled EMP table on a remote Oracle Database. This REST Data Source is beingused as source for an editable interactive grid. When a user updates an employee record in this interactive grid, which operation (HTTP Method) defined in the REST Data Source is utilized to update a record in the EMP table on the remote Oracle Database?

  • A. PUT
  • B. GET
  • C. POST

Answer: A

Explanation:
Explanation
A REST Data Source with ORDS as the REST Data Source Type is based on an AutoREST-enabled table or view on a remote Oracle Database. AutoREST enables you to perform CRUD (Create, Read, Update, Delete) operations on a table or view using standard HTTP methods. When a user updates an employee record in an editable interactive grid that uses this REST Data Source as source, the PUT operation defined in the REST Data Source is utilized to update a record in the EMP table on the remote Oracle Database. The PUT operation sends an HTTP PUT request to the REST endpoint with the primary key value of the record and the updated column values in JSON format.

NEW QUESTION # 65
Select the three types of Card Layout you can create in APEX.

  • A. Float
  • B. Horizontal(Row)
  • C. Vertical(Column)
  • D. Grid

Answer: A,B,D

Explanation:
Explanation
You can create two types of card layout in APEX: Float and Grid. Float layout displays cards in a single row that wraps to the next row when the available space is filled. Grid layout displays cards in a fixed number of columns that can be responsive to the screen size1. Vertical and Horizontal are not valid card layout types in APEX.


NEW QUESTION # 66
Which two are prerequisites to use the REST-enabled SQL feature in Oracle APEX?

  • A. REST enable the schema in the remote Oracle Database using ORDS.ENABLE_SCHEMA.
  • B. Create a database link to the remote Oracle Database in the local APEX Schema.
  • C. Install Oracle APEX in the remote Oracle Database.
  • D. On the remote Oracle Database, install ORDS 19.x or later.

Answer: A,D

Explanation:
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. Verified References: [Using REST Enabled SQL - Oracle Help Center],

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

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

Answer: B,C,D

Explanation:
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.


NEW QUESTION # 68
You can apply an authorization scheme for which three of the following components?

  • A. An entire application
  • B. A page
  • C. Specific control such as region,item or button
  • D. A session

Answer: A,B,C

Explanation:
Explanation
You can apply an authorization scheme for the following components in APEX:
A specific control such as a region, item, or button. You can select an authorization scheme from the Authorization Scheme list on the attributes page of the control. This will control the rendering and processing of the control based on the user privileges12.
A page. You can select an authorization scheme from the Authorization Scheme list on the Security page of the page definition. This will control the access to the page based on the user privileges12.
An entire application. You can select an authorization scheme from the Authorization Scheme list on the Security Attributes page of the application definition. This will control the access to the entire application based on the user privileges12.
You cannot apply an authorization scheme for a session, as a session is not a component in APEX. A session is a stateful connection between a browser and the APEX engine that persists across multiple requests and responses3. You can control session security by using session state protection, session expiration, and session isolation4.
