Exam 3V0-21.21 topic 1 question 9 discussion

Host profiles or Auto Deploy are not necessary, and 8 GB of storage is the minimum required (even if 32 GB are recommended). On a SD storage, persistent logs and scratch partition cannot be saved and must be stored on an external storage.

Host profiles must be used for this kind of installation (Not True) B. Scratch partition would need to be created on the external storage (True) C. The size of the SD cards is too small and the installation will fail (Not True, tested) D. The vSphere Auto Deploy feature must be enabled on vCenter Server (Not True)

B Unless stateless caching or a stateful install is used, vSphere Auto Deploy does not store the ESXi configuration or state on the host disk. Instead, the state is managed through an image profile and other host attributes are managed through host profiles.

To have the ESX-OSData partition locally the local disk needs minimum 32GB. ---Page 134 from course book--- The recommended ESXi 7 installation options are as follows: • An 8 GB USB or SD and an extra 32 GB local disk. The ESXi boot partitions reside on the USB or SD, and the ESX-OSData volume resides on the local disk. • A local disk with a minimum of 32 GB. The disk contains the boot partitions and ESX- Osdata volume.

answer is B

B https://blogs.vmware.com/vsphere/2021/09/esxi-7-boot-media-consideration-vmware-technical-guidance.html A configuration involving the usage of SD card or USB drives as boot media is a minimum of 8 GB SD card or USB drive + Locally attached persistent storage device for ESX-OSData partition may be used but is also not recommended. Recommended list of locally attached storage devices are listed below.In any case, if an SD or USB device is used for boot media (only SD/USB or SD/USB + local HDD/SSD disk), follow the below instructions to reduce the amount of IO sent to the SD or USB boot media:Enable the ToolsRamDisk option to offload VMTools install/upgrade IO requests on the RAM disk.Ensure the /scratch partition is configured on persistent storage like a local HDD/SSD or boot from the SAN device.

Answer is B For best performance of an ESXi 7.0 installation, use a persistent storage device that is a minimum of 32 GB for boot devices. Upgrading to ESXi 7.0 requires a boot device that is a minimum of 4 GB.
