Question
At 9:00 am each morning, all of the virtual desktops in a VDI implementation become extremely slow and/or unresponsive. The outage lasts for around 10 minutes, after which everything runs properly again. The administrator has traced the problem to a lab of thin clients that are all booted at 9:00 am each morning. Which of the following is the MOST likely cause of the problem and the BEST solution? (Select TWO).
Options
- AAdd guests with more memory to increase capacity of the infrastructure.
- BA backup is running on the thin clients at 9am every morning.
- CInstall more memory in the thin clients to handle the increased load while booting.
- DBooting all the lab desktops at the same time is creating excessive I/O.
- EInstall 10-Gb uplinks between the hosts and the lab to increase network capacity.
- FInstall faster SSD drives in the storage system used in the infrastructure.
- GThe lab desktops are saturating the network while booting.
- HThe lab desktops are using more memory than is available to the host systems.

Explanation
The problem lasts for 10 minutes at 9am every day and has been traced to the lab desktops. This question is asking for the MOST likely cause of the problem. The most likely cause of the problem is that the lab desktops being started at the same time at the beginning of the day is causing excessive disk I/O as the operating systems are being read and loaded from disk storage. The solution is to install faster SSD drives in the storage system that contains the desktop operating systems.
