Incorrect Answers:E: The DataBindings.cpx file maps individual pages to page definition files and declares which data controls defined in the DataControls.dcx file are being used by the application.References: http://www.ibm.com/developerworks/rational/library/10/customized-data-binding-to-third-party-javaserver-faces-controls/

Incorrect Answers:A: RowHeight is the height of the rows of the grid layout as a CSS length. panelDashboard stretches the panelBox children to fit within the width of a column and the specified row height.B: ADF has a default styleClass called "AFStretchWidth" which could auto adjust the table width to let it occupy the whole horizontal space.References: http://docs.oracle.com/cd/E12839_01/apirefs.1111/e12419/tagdoc/af_panelGroupLayout.html

A: A Threshold represents a significant value range like quota, target or limit value etc. When the indicator falls into one of the threshold ranges, it means certain criteria have been met or not. Different threshold ranges in gauges may have different colors, which you may customize.C: The Vertical Status Meter and Status Meter are meters with a rectangular indicator placed in a bounding box. It looks like a mercury barometer.Incorrect Answers:B: The Indicator shows the metric value of the Gauge. There are three types of indicators for Dial Gauges: Line, Needle and Fill. Line and Needle are rotating pointers to show the metric value by pointing to certain angle on the dial. The Needle indicator is thicker than the Line indicator. Fill is a slice or section of the dial that fills from the minimum value up to the metric value. Users may specify the indicator fill color and border color.D: The simplest data model for a Gauge is a single metric value, which can be specified by the value attribute. In addition, the threshold, minimum and maximum values can also be specified by Threshold tag, and the minValue and maxValue attributes respectively.References: https://docs.oracle.com/cd/E21764_01/apirefs.1111/e12418/tagdoc/dvt_gauge.html

A: Declarative view objects, those are view objects that don't actually specify a hard coded query. Instead ADF creates their query at runtime, and it does it based on the data that is requested in your UI layer. This can be a huge saver of both DB resources and network resources.C: Just as with normal mode view objects, you can link view objects that you create in declarative SQL mode to other view objects to form master-detail hierarchies of any complexity.E: At runtime, when ADF Business Components works with JDBC to pass a query to the database and retrieve the result, the mechanism to retrieve the data is the SQL query. As an alternative to creating view objects that specify a SQL statement at design time, you can create entity-based view objects that contain no SQL statements. This capability of the ADF Business Components design time and runtime is known as declarative SQL mode. When the data model developer works with the wizard or editor for a view object in declarative SQL mode, they require no knowledge of SQL. In declarative SQL mode, the view object's metadata causes the ADF Business Components runtime to generate the SQL query statementsReferences: http://docs.oracle.com/cd/E37975_01/web.111240/e16182/bcquerying.htm#ADFFD1992

A: The Value field (in the Edit Attribute dialog) allows you to specify a static default value for the attribute when the Value Type is set to Literal. For example, you can set the default value of the ServiceRequest entity object's Status attribute to Open, or set the default value of the User entity object's UserRole attribute to user.B: You can use a Groovy expression to define a default value for an attribute. This approach is useful if you want to be able to change default values at runtime.D: Groovy scripting logic is similar to Expression Language (EL)References: http://docs.oracle.com/cd/E15586_01/web.1111/b31974/bcentities.htm#BABFBJAI

C: View scope: The object is available until the view ID for the current view activity changes. This becomes handy when you use partial page rendering. If you have a dependent list box, you might send a server request to refresh the list box. When a response is returned, the request scope will be gone but the view scope will be still there.D: A pageFlow scope exists for each task flow instance and has a lifespan between request and session scope. The lifetime of the scope spans across all pages in a bounded task flow.E: Session scope: The object is available for the duration of the session, which is user instance-specific. A use case for a session scope bean is a user info bean that stores information about a user, which is read from the database or an LDAP server, to avoid unnecessary queries.Incorrect Answers:A: Request scope: The object is available from the time an HTTP request is made until a response is sent back to the client. From another perspective, a request scope starts with a request to be issued from one view to another for navigation cases that don't perform a redirect but a default server-side forward. The scope spans across all non-view activities that follow the view of interest to the next view activity.B: The backing bean scope is comparable to the request scope, with the difference in that it exists for a specific client component. In general, all managed beans used in reusable components should be configured to backingBean scope. For example, bounded task flows that are designed to be regions on a page should use the backingBean scope if more than one instance of the task flow is expected to be on a single page.F: Application scope: An application scope object is available for the duration of the application and is shared among users. This scope may be used to hold static objects that are the same for all users.References: http://xmlandmore.blogspot.se/2009/10/types-of-scopes-in-fusion-web.html

Incorrect:Not C: Managed beans can have the following scopes: Application, session, PageFlow, view, request, BackingBean.Not E: JavaServer Faces (JSF) technology provides the tools to implement user interfaces that are easy to extend and reuse. Templating is a useful Facelets feature that allows you to create a page that will act as the base, or template, for the other pages in an application. By using templates, you can reuse code and avoid recreating similarly constructed pages. Templating also helps in maintaining a standard look and feel in an application with a large number of pages.References: http://docs.oracle.com/javaee/6/tutorial/doc/giqxp.html

When you create an entity object from an existing table, first JDeveloper interrogates the data dictionary to infer the following information:The primary and unique key attributes The mandatory flag on attributes, based on NOT NULL constraints The length and precision of each attribute The Java-friendly entity attribute names from the names of the table's columns (for example, USER_ID -> UserId) The SQL and Java data types of each attribute based on those of the underlying column The relationships between the new entity object and other entities based on foreign key constraints References: http://docs.oracle.com/cd/E48682_01/web.1111/b31974/bcentities.htm

When you want to show the user a set of master rows, and for each master row a set of coordinated detail rows, then you can create view links to define how you want the master and detail view objects to relate. To create an association-based view link, you use the Create View Link wizard. Note: A master-detail relationship is established when a view link is created to associate two view object instances. A view link represents the relationship between two view objects, which is usually, but not necessarily, based on a foreign-key relationship between the underlying data tables. The view link associates a row of one view object instance (the master object) with one or more rows of another view object instance (the detail object).References: https://docs.oracle.com/middleware/1213/adf/develop/adf-bc-vo-master-detail.htm#ADFFD23705
