Question #1 Topic 1

Which statement is true about the use of data controls in JSF? (Choose the best answer.)

A. Only Oracle ADF Business Components can be exposed as data controls.
B. Dragging a data control onto a JSF page generates a Java class that acts as a managed bean.
C. An XXXpagedef.xml file holds detailed information about a JSF page’s use of data and operations exposed through ADF Data Controls.
D. Data controls eliminate the need to use expression language in your JSF code for binding the UI to data.
E. A Databindings.cpx file holds names of managed beans that you map to UI elements.

Correct Answer: D 🗳️
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.

Correct Answer: C 🗳️
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.

Question #3 Topic 1

Which two statements ate true about a dvt:gauge component? (Choose two.)

A. dvt:thresholdSet with dvt:threshold tags can be used to define ranges of data and coloring for a gauge.
B. The style of the dial in a dial gauge is fixed.
C. A gauge component can render as a vertical status meter.
D. Gauge data range must start from 0.

Correct Answer: AC 🗳️
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.

Question #4 Topic 1

Consider a bounded task flow input parameter called employeeId of type oracle.jbo.domain.Number. When defining the parameter in the bounded task flow, if you do not define a value (destination) for the parameter, where does it get written to? (Choose the best answer.)

A. #{employeeId}
B. #{employee.employeeId}
C. #{pageFlowScope.employeeId}
D. #{pageFlowScope.employee.employeeId}
E. #{backingBeanScope.employeeId}
F. #{backingBeanScope.employee.employeeId}

Reveal Solution Discussion

Correct Answer: C 🗳️
For example, the page might specify #{pageFlowScope.empno} as a page parameter and a bounded task flow might specify #{pageFlowScope.employeeID} as the value of an input parameter definition.
The from-value on the view activity input page parameter would be #{pageFlowScope.employeeID} and the to-value would be #{pageFlowScope.empno}. This enables reuse of both the page definition and bounded task flow because you don't have to redefine parameters for every context in which each is used.
