Which three of the following are use cases of Automations?
- A. Approving specific requests
- B. Deleting a database record based on an end user's request
- C. Sending email alerts at a particular time of the week
- D. Monitoring log tables and raising an alert when there is an issue
Answer: A,C,D
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 # 60
Which statement is true about session state management in Oracle APEX?
- A. Multiple number of sessions cannot exist in the database at the same time
- B. A user cannot run multiple instances of an application simultaneously in different browser programs.
- C. APEX Sessions are logically and physically distinct from Oracle database sessions used to service page requests.
Answer: C
Explanation:
Explanation
Session state management is a feature that enables developers to store and retrieve values for a user as the user navigates between different application pages. A session is a logical construct that establishes persistence (or stateful behavior) across page views. Each session is assigned a unique identifier (or session ID). The statement that is true about session state management in Oracle APEX is:
APEX Sessions are logically and physically distinct from Oracle database sessions used to service page requests. APEX Sessions are stored in memory within an Application Express engine process while Oracle database sessions are stored in memory within an Oracle database process. The other statements are false because:
A user can run multiple instances of an application simultaneously in different browser programs by using different session IDs.
Multiple number of sessions can exist in the database at the same time for different users or applications.

- B. You can build interactive reporting apps based on data from disparate systems
- C. APEX eliminates middle-tier application logic.
- D. Application definition is not stored in the database.
- E. Processing and data manipulation is not executed in the database.
Answer: B,C
Explanation:
Explanation
Oracle APEX is a low-code application development platform that enables developers to build scalable, secure, and data-driven web and mobile apps. Some of the statements that are true about Oracle APEX are:
APEX eliminates middle-tier application logic. APEX runs entirely within Oracle Database and does not require any additional middleware or application server to function. This simplifies the architecture and reduces the complexity, cost, and security risks of deploying applications.
You can build interactive reporting apps based on data from disparate systems. APEX supports various data sources, such as local database, REST Enabled SQL Service, REST Data Source, Web Source Module, etc. You can use these data sources to create interactive reports that allow end users to filter, sort, search, aggregate, and visualize data from different sources.
The other statements are false because:
Application definition is stored in the database. APEX stores the metadata of the application components, such as pages, regions, items, buttons, etc., in the database tables.
Processing and data manipulation is executed in the database. APEX leverages the power and performance of Oracle Database to process and manipulate data using SQL and PL/SQL.
Running an APEX app does not need client software. APEX apps are web-based and can be accessed from any browser on any device without installing any client software. Verified References: [Oracle Application Express (APEX) - Oracle Help Center], [Platform - Oracle APEX]
NEW QUESTION # 67
You can create a report in which of the three following methods?
- A. Create a report region on a page in an application
- B. Create a report as a new page in an application
- C. Create a report when you create a new database application
- D. Create a report from Object Browser
Answer: A,B,C
Explanation:
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.

Answer: A,C,D
Explanation:
Explanation
A map is a type of component that enables users to view and manage data based on geographic locations. A map consists of a background map and spatial geometry objects that are sourced from data in a table or from a REST data source. Spatial geometry objects are shapes that represent real-world features on a map, such as points, lines, polygons, or heat maps. Three of the supported spatial geometry objects in Oracle APEX are:
Polygons: A polygon is a closed shape that consists of three or more vertices connected by straight line segments. A polygon can represent an area on a map, such as a country, a state, a city, or a building. A polygon can have different colors, patterns, or borders to indicate different attributes or categories of the data.
Heat map: A heat map is a type of visualization that uses color gradients to show the density or intensity of data values in a geographic area. A heat map can represent the distribution or variation of a numeric variable on a map, such as population, income, crime rate, or temperature.
Points: A point is a zero-dimensional shape that represents a single location on a map. A point can have different symbols, sizes, or colors to indicate different attributes or categories of the data. A point can also have a label or a tooltip to display additional information about the data.

The Movies faceted search report is filtered only when the Apply button for a selected facet is clicked. What must be done in the Page Designer so that report filtering is automatically executed when any facet value changes?
- A. Navigate to the faceted search region Attributes, and turn off the show Facet Name attribute.
- B. Navigate to the faceted search region Attributes, and turn off the show Facet Name attribute. Then, navigate to each facet and in the Property Editor, turn on client-Side Filtering.
- C. Navigate to the faceted search region Attributes, and disable the Batch Facet Changes attribute
- D. Navigate to each facet and then in the Property Editor, turn on client-Side Filtering.
Answer: C
Explanation:
Explanation
A faceted search page is a type of page that allows end users to filter data by applying one or more facets. A facet is a set of filters based on a column or expression. By default, when end users select a facet value, they need to click on an Apply button for that facet to apply the filter to the report. To make report filtering automatically executed when any facet value changes, you need to navigate to the faceted search region Attributes, and disable the Batch Facet Changes attribute. The Batch Facet Changes attribute determines whether end users need to click on an Apply button for each facet or not. When this attribute is disabled, the report is automatically refreshed when any facet value changes. The other options are not relevant to the report filtering behavior.
