to XenOesktop.
E. Ensure secure communication between endpoint devices and desktops by using the Citrix ICA client
and setting the encryption level to basic.
F. Ensure secure communication between endpoint devices and desktops by using the Citrix ICA client
and setting the encryption level to 128bit.
Answer: ABCF
QUESTION 7
Scenario: A Citrix Engineer is considering making a change to the design document in order to allow the alternate address of the XenApp server to be given to a particular set of client devices when users attempt to access published applications. What are three settings that the Citrix Engineer must configure in order to use the alternate address of the XenApp servers for the particular set of client devices? (Choose three.)
A. Enable the spanning tree protocol.
B. Configure port forwarding on the managed switches.
C. Configure the firewall for network address translation.
D. Configure the XenApp Servers with an alternate address.
