ABD
Explanation
A. Correct: You can control the diagnostics setting through configuration within your Windows Azure–hosted application.
B. Correct: Although the Windows Azure VMs get recycled when the role restarts, saving the logs to the Windows Azure storage system outside of your VM would ensure that they are available.
