NEW QUESTION # 13
Which three of the following are use cases of Automations?

• A. Monitoring log tables and raising an alert when there is an issue
• B. Approving specific requests
• C. Sending email alerts at a particular time of the week
• D. Deleting a database record based on an end user's request

Answer: A,B,C

Explanation:
Explanation
Automations are a sequential set of PL/SQL actions that are triggered by query results. They are used to monitor data and then perform the appropriate action2. Some use cases of automations are:
Monitoring log tables and raising an alert when there is an issue. For example, an automation can query a log table for any errors and send an email notification to the administrator if any errors are found2.
Approving specific requests. For example, an automation can query a table for any pending requests and approve them automatically based on some criteria2.
Sending email alerts at a particular time of the week. For example, an automation can query a table for any overdue tasks and send a reminder email to the assignees every Monday2.
Deleting a database record based on an end user's request is not a use case of automations, as it does not involve querying data and triggering actions based on the query results. This can be achieved by using a PL/SQL process or a dynamic action on the page where the user requests the deletion34.

NEW QUESTION # 16
Which three of the following statements are TRUE about Data Synchronization?

• A. Data Synchronization enables developers to automatically sync the contents of a local table with the data from a REST service.
• B. Helps in Providing efficient reporting on large data sets coming 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.

Answer: A,B,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 # 17
Which statement is true about creating and using an interactive grid?

• A. For both editable and noneditable interactive grids, end users can change the report layout and create private reports.

NEW QUESTION # 18
What are the three types of List of Values(LOV) you can create on a page?

• A. Popup LOV
• B. Cascading LOV
• C. Dynamic LOV
• D. Static LOV

Answer: B,C,D

Explanation:
Explanation
A list of values (LOV) is a definition that provides a set of display values and return values for a page item or a report column. A LOV can be created at the application level as a shared component or at the page level as a local component. There are three types of LOVs that you can create on a page:
Static LOV: A static LOV is based on a fixed list of display values and return values that you specify when you create the LOV. A static LOV does not change unless you edit it manually.
Cascading LOV: A cascading LOV is based on another parent LOV that determines the values of the child LOV. A cascading LOV changes dynamically depending on the selection made in the parent LOV.
Dynamic LOV: A dynamic LOV is based on a SQL query that returns display values and return values from the database. A dynamic LOV changes dynamically depending on the data in the database.

NEW QUESTION # 19

NEW QUESTION # 25
What three components must be considered whilemigrating an APEX app betweenenvironments?

• A. Move the sessions data
• B. Move the application definition and all associated files
• C. Move the database objects
• D. Move the images

Answer: B,C,D

Explanation:
Explanation
To migrate an APEX app between environments, such as from development to production, you need to consider three components that make up an APEX app:
Database objects: These are the tables, views, procedures, functions, packages, triggers, sequences, synonyms, and other schema objects that store or manipulate the data used by the app. You need to move these objects from the source schema to the target schema using tools such as SQL Developer, Data Pump Export/Import, or Data Workshop.
Images: These are the static files, such as images, CSS files, JavaScript files, or PDF files, that are used by the app for display or download purposes. You need to move these files from the source web server to the target web server using tools such as FTP, SCP, or File Explorer.
Application definition and all associated files: These are the metadata files that define the app components, such as pages, regions, items, buttons, processes, validations, computations, dynamic actions, shared components, and so on. You also need to include any supporting object definitions or data scripts that are used to create or populate database objects for the app. You need to move these files from the source APEX instance to the target APEX instance using tools such as App Builder Export/Import or One-click Remote Application Deployment.

NEW QUESTION # 26
The APEX engine uses which component as a key for tracking each user's session state?

• A. APEX_USER
• B. LDAP_USER
• C. APP_USER
• D. HTTP_USER

Answer: C

Explanation:
Explanation
APP_USER is a built-in substitution string in Oracle APEX that stores the user name of the current user session. The APEX engine uses APP_USER as one component of a key for tracking each user's session state.
As a user navigates from page to page, the APEX engine sets the value of APP_USER to identify the user. The APEX engine also uses APP_USER to perform security checks and conditional processing. You can reference APP_USER using different syntax depending on the context, such as SQL, PL/SQL, or static text.
