NEW QUESTION # 39
Select the three types of Facets you can create in APEX.
- A. Checkbox Group
- B. Text Area
- C. Range
- D. Input Field
Answer: A,C,D
Explanation:
Explanation
A facet is a type of component that provides a set of display values and return values for a faceted search region or a smart filters region. A facet can be based on either static values or dynamic values from a list of values (LOV). A facet can also have different display styles depending on its type and settings. Three of the types of facets that you can create in APEX are:
Range: A range facet displays numeric values in either buckets or sliders that users can select or adjust to filter the search results. A range facet can have either static values or dynamic values based on an LOV or SQL query.
Checkbox Group: A checkbox group facet displays multiple options that users can select or deselect to filter the search results. A checkbox group facet can have either static values or dynamic values based on an LOV or SQL query.
Input Field: An input field facet displays a text field that users can enter text to filter the search results.
An input field facet does not have any values but uses an operator to compare the user input with the data.
NEW QUESTION # 40
Which statement is true about importing an APEX application?
- A. You cannot change the application ID during the import process.
- B. The import process does not import the supporting objects defined during the export.
- C. You cannot import an APEX application exported from a latest APEX version to an old APEX version.
Answer: C
Explanation:
Explanation
As a general rule, you cannot import an application created in a newer release of APEX into an earlier version.
This is because the newer release may have features or attributes that are not supported or recognized by the older version. For example, you cannot import an application created in APEX 21.2 into APEX 19.2.
However, you can import an application created in an older release into a newer one, as long as the application is compatible with the newer release. For example, you can import an application created in APEX 18.2 into APEX 21.2, but you may need to upgrade or modify some components to use the latest features.
NEW QUESTION # 41
In an Employee form, the 'Commission' and 'Hire Date' fields are enabled only if the Job is
'Salesman'. This can be achieved by which feature of APEX?
- A. PL/SQL procedure
- B. Processing
- C. Conditional SQL
- D. Dynamic Actions
Answer: D
Explanation:
Explanation
In an Employee form, the 'Commission' and 'Hire Date' fields are enabled only if the Job is 'Salesman'. This can be achieved by using Dynamic Actions in APEX. Dynamic Actions are declarative components that define client-side behavior without writing JavaScript code. You can create Dynamic Actions on items, buttons, or regions of a page by specifying an event, a condition, an action, and other properties. In this scenario, you can create a Dynamic Action on Job item with Change as event, Execute JavaScript Code as action, and use jQuery to enable or disable Commission and Hire Date fields based on Job value. Processing, Conditional SQL, and PL/SQL procedure are not features of APEX that can achieve this requirement without writing JavaScript code.

NEW QUESTION # 45
What three are the uses of Collections in APEX?
- A. Collections enable you to store rows and columns in the current session into database tables
- B. You insert, update, and delete collection information using PL/SQL APIAPEX_COLLECTION.
- C. Collections can be accessed, manipulated, or processed during a user's specific session.
- D. Use collections to temporarily capture one or more nonscalar Values.
Answer: B,C,D
Explanation:
Explanation
Collections are temporary tables that store session-specific data in memory. They can be used for various purposes in APEX applications. Some uses of collections are:
You insert, update, and delete collection information using PL/SQL API APEX_COLLECTION. This API provides several procedures and functions to manipulate collections and their members.
Use collections to temporarily capture one or more nonscalar values. For example, you can use collections to store the results of a query, the values of page items, or the selections of a report.
Collections can be accessed, manipulated, or processed during a user's specific session. For example, you can use collections to pass data between pages, perform calculations on collection members, or create reports based on collections.
Collections do not enable you to store rows and columns in the current session into database tables.
Collections are stored in memory and are not persistent across sessions.
NEW QUESTION # 46
To highlight certain rows in the interactive report based on a condition, you must:
- A. Provide a conditional SQL query
- B. Choose a condition in Format > Highlight
- C. Rows cannot be highlighted in an Interactive report
- D. Edit the rows in the report and select a color
Answer: B
Explanation:
Explanation
To highlight certain rows in the interactive report based on a condition, you must choose a condition in Format
> Highlight. This option allows you to apply a conditional formatting rule to the report, which changes the appearance of the rows that match the condition. You can specify the condition type, expression, column, operator, and value. You can also choose the highlighting style, such as background color, text color, or icon.
The other options are incorrect because:
Provide a conditional SQL query: This option will not highlight certain rows in the interactive report based on a condition. It will filter the data in the report by applying a WHERE clause to the SQL query that defines the report source.
Edit the rows in the report and select a color: This option will not highlight certain rows in the interactive report based on a condition. It will modify the data in the report by using inline editing or modal dialog editing. You cannot select a color for the rows in this option.
Rows cannot be highlighted in an Interactive report: This option is false. Rows can be highlighted in an Interactive Report by using the Format > Highlight option.

NEW QUESTION # 48
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. GET
- B. PUT
- C. POST
Answer: B
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.

commission yn/check TRUE, FALSE
Which statement is true about the commission yn column?
- A. It will restrict acceptable values to Y or N.
- B. It will default to FALSE.
- C. It will restrict acceptable values to TRUE or FALSE.
- D. It will default to TRUE.
Answer: C
Explanation:
Explanation
The commission yn column will restrict acceptable values to TRUE or FALSE because of the /check modifier in the column name. This modifier adds a check constraint to the column based on the values specified after it.
The yn suffix indicates that the column is of type VARCHAR2(1). The other options are incorrect because they do not reflect the effect of the /check modifier or the yn suffix. Verified References: Using Quick SQLAbout Quick SQL Shorthand Syntax
NEW QUESTION # 50
Which two statements are TRUE about Dynamic Actions?
- A. Dynamic Actions require complex client side Javascript code
- B. Dynamic actions provide a way to define complex client-sidebehaviordeclaratively without the need for JavaScript.
- C. It is not possible to debug Dynamic Actions from the Developer Toolbar
- D. More dynamic actions you add to a page, the greater your overall page size.
Answer: B,D
Explanation:
Explanation
Dynamic actions provide a way to define complex client-side behavior declaratively without the need for JavaScript. You can create dynamic actions on items, buttons, or regions of a page by specifying an event, a condition, an action, and other properties1. However, more dynamic actions you add to a page, the greater your overall page size. This can affect the performance and user experience of your application2. It is possible to debug dynamic actions from the Developer Toolbar by using the Debug option3. Dynamic actions do not require complex client-side JavaScript code, but they can optionally include custom JavaScript code as an action or a condition1.
NEW QUESTION # 51
Which three statements are TRUE about Shared Components?
- A. Breadcrumbs, Lists, and Navigation Bar entries are examples of shared components
- B. Once you create a Shared Component, you can add them to any page within an APEX application in any workspace.
- C. Shared components are common elements that can be displayed or applied on any page within an application
- D. Once you create a Shared Component, you can add them to any page within your APEX application
Answer: A,C,D
Explanation:
Explanation
Shared components are common elements that can be displayed or applied on any page within an application.
Once you create a shared component, you can add them to any page within your APEX application. However, shared components are specific to each application and workspace, so you cannot add them to any page in any workspace4. Breadcrumbs, lists, and navigation bar entries are examples of shared components that can be used for navigation purposes4.

Which three of the following are use cases of Automations?
- A. Sending email alerts at a particular time of the week
- B. Approving specific requests
- C. Monitoring log tables and raising an alert when there is an issue
- 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.
