• Question 324:

  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. A network connection could interfere with other services on the device, such as the ability to receive phone calls or SMS on a phone.
  E. Devices can only support one HttpConnection at a time; therefore, network access from multiple threads must be serialized.
  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. A network connection could interfere with other services on the device, such as the ability to receive phone calls or SMS on a phone.
