VMware Carbon Black Cloud Professional (2021) — Question 78

An end-user is experiencing a black screen when connecting to their virtual desktop. After a few seconds, the connection closes.
Which could be the cause of the issue? (Choose three.)

Answer options

• A. The Client machine video memory is too high.
• B. There is a vRAM shortage on the Horizon virtual machine.
• C. The Horizon Virtual Machine video memory is too high.
• D. There is an incorrect firewall configuration.
• E. The incorrect video driver version is installed on the Horizon virtual machine.

Correct answer: B

Explanation

The correct answer is B because a shortage of vRAM on the Horizon virtual machine can prevent it from rendering the desktop properly, leading to a black screen. The other options, while potentially problematic, do not directly cause the black screen and immediate disconnection issue described in the question.
