B) A JTWI device must support Real Time Streaming Protocol (RTSP) for media file download of all supported media formats.
C) A JTWI device must support WAV file playback.
D) A JTWI device must support MP3 file playback.
E) A JTWI device must support HTTP for media file download of all supported media formats.

2. Which three are basic interface types addressed by the Generic Connection Framework?
(Choose three.)

A) basic serial output connection
B) circuit-oriented mechanism
C) location-oriented mechanism
D) telephony-oriented mechanism
E) basic serial input connection

3. Given the MIDlet code:
11. DatagramConnection dgc
(DatagramConnection)Connector.open("datagram://:444");
1 2. Datagram datagram = dgc.newDatagram(20);
1 3. dgc.receive(datagram);
1 4. byte[] data = datagram.getData();
1 5. String s = new String(data);
1 6. list.append(s, null);
1 7. System.out.println("Datagram received: " + s);
Which two are true regarding the portability of the code between devices? (Choose two.)

A) Installation will fail on devices that do not support datagrams.
B) The code is portable because all the classes and interfaces used are defined in the CLDC.
C) Datagrams may not be supported on all platforms.
D) Port 444 may be restricted or ignored by some MIDP implementations.

4. Given a MIDP 2.0 device supports alpha blending, a MIDlet needs to render semi- transparent images of size 10x10 pixels. However, these images need to be generated at runtime. That is, they CANNOT be loaded as PNGs. What is the correct way to create a
10x10, red, semi-transparent image, using only the MIDP 2.0 API?

A) use createImage() to create a mutable Image, then fill it with red pixels
B) use createImage() to create a mutable Image; first fill it with white pixels, then fill it with red pixels
C) use createRGBImage() to create an immutable Image from ARGB data with the desired values
D) This is not possible. An Image with semi-transparency CANNOT be created at runtime.

5. Given:
11. String base = "44";
12. for(int ccnt=0; ccnt < 5; ccnt++) {
1 3. try {
1 4. String temp = base + Integer.toString(ccnt);
1 5. PushRegistry.registerConnection
1 6. ("datagram://:" + temp, MIDletName, "*");
1 7. break;
1 8. } catch (IOException x) {
1 9. continue;
2 0. }
2 1. }
Which two are true? (Choose two.)

A) attempts a number of times to register a datagram connection for use by the MIDlet specified by MIDletName
B) attempts to reserve a datagram connection for the MIDlet specified by MIDletName, even though the MIDlet may NOT depend on push connections
C) registers 5 datagram connections for use by the MIDlet specified in MIDletName
D) guarantees that at least 1 datagram connection will be registered for use by the MIDlet specified by MIDletName
