• Question 283:

  Which three statements are true regarding the handling of wireless connections? (Choose three.)

  A. Network connections should never be performed on a separate thread, so problems can be handled quickly.
  B. Performing network operations on the same thread used by the display is likely to block refreshes of the display until the network operations complete.
  C. The connection could unexpectedly terminate while processing the input or output streams.
  D. Devices can only support one HttpConnection at a time; therefore, network access from multiple threads must be serialized.
  E. A network connection could interfere with other services on the device, such as the ability to receive phone calls or SMS on a phone.
  B. Performing network operations on the same thread used by the display is likely to block refreshes of the display until the network operations complete.
  C. The connection could unexpectedly terminate while processing the input or output streams.

• Question 287:

  A MIDlet makes its only attempt to register a push connection on a JTWI device using:

  PushRegistry.registerConnection( "datagram://:79", midlet, "10.0.0.???"); Which is true?

  A. The call to registerConnection() causes an exception, because the string 10.0.0.??? is an illegal argument.
  B. The MIDlet accepts datagram push connections on port 79 only from IP addresses in the range 10.0.0.0 to 10.0.0.255.
  C. The MIDlet accepts datagram push connections on port 79 only from IP addresses in the range 10.0.0.100 to 10.0.0.255.
  D. The MIDlet accepts datagram push connections on port 79 only from IP addresses in the range 10.0.0.100 to 10.0.0.255 and on any other port from IP addresses other than those in the range 10.0.0.100 to 10.0.0.255.
  C. The MIDlet accepts datagram push connections on port 79 only from IP addresses in the range 10.0.0.100 to 10.0.0.255.

• Question 288:

  Which URL indicates the intention for one JTWI device to communicate with another JTWI device?

  A. cbs://+18005551234:1234
  B. sms://+18005551234
  C. sms://+18005551234:1234

  C. sms://+18005551234:1234

• Question 289:

  What is true when an enumeration applies both a RecordFilter class and RecordComparator class on a record store?

  A. The records that match the search criteria in RecordFilter will be returned using the ordering defined by RecordComparator.
  B. The return order of the result set is undefined.
  C. The records that match the search criteria in RecordComparator will be returned using the ordering defined by RecordFilter.
  D. All records will always be available as part of the enumeration result set.
  E. An enumeration CANNOT apply both a RecordFilter and RecordComparator.
  A. The records that match the search criteria in RecordFilter will be returned using the ordering defined by RecordComparator.

• Question 290:

  Click the Exhibit button. The red collision rectangle around each Sprite in the image is NOT part of the actual image. The two Sprite objects intersect in the application precisely as shown. Which two are true? (Choose two.)

  

  A. For the two Sprite objects to be considered in collision, collidesWith() must be invoked on both objects.
  B. If Sprite 1 is being tested for collision with Sprite 2 using pixel-level collision detection, the two Sprite objects will NOT be in collision.
  C. The most efficient way to detect collision is to use collision detection based solely on the collision rectangles.
  D. For the two Sprite objects to be considered in collision, each Sprite must have no more than one frame.
  B. If Sprite 1 is being tested for collision with Sprite 2 using pixel-level collision detection, the two Sprite objects will NOT be in collision.
  C. The most efficient way to detect collision is to use collision detection based solely on the collision rectangles.
