1z0-770 Exam Dumps - Oracle Application Development Certification Questions and Answers

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.

 A modal dialog is a type of page mode that displays an overlay window within the viewport when a button is pressed. A modal dialog is a stand-alone page that does not interact with the base page where it was launched. A modal dialog blocks access to the base page until it is closed by the user. A modal dialog can be used for various purposes, such as displaying additional information, confirming an action, or collecting user input.

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.

A REST Data Source is a logical representation of an external web service in Oracle APEX. It can contain one or many Operations, which are the references to a concrete external web service endpoint. Oracle APEX supports three types of REST Data Sources: REST Enabled SQL Query, Web Source Module, and Generic REST Data Source. Oracle APEX provides direct integration of REST Data Sources in interactive reports and grids, as well as other components. REST Data Sources can support various authentication methods, such as Basic, OAuth2, or Custom. References: [Understanding REST Data Sources] and [Creating a REST Data Source]

The Create Page wizard supports three form types that you can create: Interactive Grid, Form, and Master Detail4. An interactive grid is a report that allows users to view and edit data in a tabular format. A form is a page that enables users to update a single row in a database table or view. A master detail is a page that reflects a one-to-many relationship between two tables or views4. An interactive report is not a form type, but a report type that allows users to customize the report layout and filter data interactively5.

All of the options listed are different kinds of page components that you can create in APEX. A page component is an area of a page that serves as a container for content. Each page component contains a different type of content, such as HTML, a report, a form, a chart, a list, a breadcrumb, PL/SQL, a tree, a URL, or a calendar. You can create page components by using the Create Page Wizard, dragging and dropping from the Gallery pane in Page Designer, or using the context-sensitive menu in the Rendering tree in Page Designer.

Template options provide developers with a declarative approach to applying different styles to components on an Oracle APEX page. Developers can use template options to declaratively apply CSS modifiers to the templates they have chosen for pages, regions, reports, lists, breadcrumbs, items and buttons. Developers can use template options in all of the following ways:

• Applying different colors or accents. Developers can use template options to change the color scheme or accent color of components, such as buttons, lists, or regions.
• Rendering buttons in different styles, with and without icons. Developers can use template options to change the shape, size, style, and icon of buttons on a page.
• Applying different spacing and padding. Developers can use template options to adjust the spacing and padding of components, such as regions, items, or reports.
• Displaying form fields with different alignments. Developers can use template options to change the alignment of form fields and labels, such as left-aligned, right-aligned, or top-aligned.

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.

An authentication scheme is a rule that determines if a user is authorized to access a specific component or feature of an application, such as a page, region, button, item, etc. An authentication scheme type defines how users are authenticated when they access an application. The authentication scheme type that supports authentication with social networks and enterprise identity providers that support OpenID Connect or OAuth2 standards is Social Sign-In. Social Sign-In supports authentication with Google, Facebook, and other social networks that support these standards. The other authentication scheme types do not support authentication with social networks or enterprise identity providers. They are:

• HTTP Header Variable: Authenticate users externally by storing the username in a HTTP Header variable set by the web server.
• SAML Sign-In: Delegates authentication to the Security Assertion Markup Language (SAML) Sign In authentication scheme.
• Open Door Credentials: Enable anyone to access your application using a built-in login page that captures a user name. Verified References: [Understanding Preconfigured Authentication Schemes - Oracle Help Center], [Social Sign-In - Oracle Help Center]
