Objective 6.5 Answers
1. Correct Answers: E
A. Incorrect: Enabling the Desktop Background option on Remote Desktops
decreases performance because the image must be transmitted across the network
to the Remote Desktop client. Therefore, this option must not be enabled when a
slow dial-up connection is being used.
B. Incorrect: The Show Contents Of Window While Dragging option must be disabled
when a slow dial-up connection is being used because it causes unnecessary
traffic across the network connection.
C. Incorrect: Menu And Window Animation must be disabled when a slow dial-up
connection is being used. Although this option provides the Remote Desktop with
a richer graphical user interface, it causes unnecessary traffic to be sent across the
network.
D. Incorrect: Enabling the Themes performance option for a Remote Desktop connection
causes the client to retrieve customized aspects of the user interface, such
as fonts and colors. This transfer causes less traffic than the other performance
options, but must still be disabled for best performance. Enabling the Themes
option does not automatically cause the desktop background to be transferred,
even if the background is part of the theme.
E. Correct: Enabling Bitmap Caching reduces the number of times a single image
must be sent between the Remote Desktop client and server. Therefore, enabling
this option reduces network traffic and can dramatically improve performance on
slow dial-up connections.
2. Correct Answers: A and B
A. Correct: HTTP is the protocol used by IIS and Internet Explorer for exchanging
files. Remote Desktop Web connection uses HTTP to prompt the user to connect.
By default, HTTP uses port 80, though that can be changed. After the connection
has been established, Remote Desktop Protocol (RDP) is used exclusively.
B. Correct: RDP is used by the Remote Desktop, Remote Desktop Web connection,
and Remote Assistance for exchanging video, sound, keyboard, and mouse data.
By default, RDP uses TCP port 3389. Though you can change the TCP port used
for RDP on the Remote Desktop server computer, the Remote Desktop Web connection
client must always use the default port. Remote Desktop Web connection
also requires HTTP to initiate the session from a browser.
C. Incorrect: SMTP is the protocol used to exchange messages between post
offices. Remote Desktop Web connection does not require SMTP.
