NEW QUESTION 34
An architect makes the design decision to install ESXi on embedded and resilient 8 GB SD cards.
What is the impact of this design decision?
- A. The size of the SD cards is too small and the installation will fail
- B. Scratch partition would need to be created on the external storage
- C. Host profiles must be used for this kind of installation
- D. The vSphere Auto Deploy feature must be enabled on vCenter Server
Answer: B
Explanation:
