Section 1: ESXi Installation and Setup Flashcards
What are the 2 core components of vSphere?
ESXi and vCenter Server
What is vSphere ESXi?
Elastic Sky X integrated is an enterprise-class, type-1 hypervisor serving as the virtualization platform on which you can create and run VMs and virtual appliances.
What is vCenter Server?
Acts as a central administrator for ESXi hosts connected in a network and lets you pool and manage the resources of multiple hosts.
How many CPU cores are required on ESXi hosts?
2
What setting (bit*) needs to be enabled for the CPU in the BIOS of the ESXi host?
The NX/XD bit
What is the minimum and recommended amount of RAM in an ESXi host?
Minimum: 4 GB
Recommended: 8 GB
What must be enabled on x64 CPUs in order to support 64-bit VMs?
Support for hardware virtualization (Intel VT-x or AMD RVI) must be enabled in the BIOS/UEFI.
What is the minimum speed for ethernet adapters on an ESXi host?
1 Gbps
What are the different boot options for ESXi 6.7?
- Boot from UEFI (hard drives, CD-ROM drives, USB)
- Auto Deploy (Network boot and provisioning)
What is the minimum amount of space needed on a boot device to install ESXi 6.7?
1 GB
When booting from a local disk, SAN, or iSCSI LUN, what size disk is required to allow for the creation of the VMFS volume and a __ size scratch partition on the boot device?
A 5.2 GB disk to create VMFS volume for a 4 GB scratch partition.
If a scratch partition cannot be created on the boot device, what does the installer do?
The installer attempts to allocate a scratch region on a seperate local disk.
If a local disk cannot be found, the scratch partition is put on the ESXi host ramdisk, linked to /tmp/scratch.
True or False. For best performance and memory optimization, do not leave /scratch on the ESXi host ramdisk.
True.
What are the different supported remote management tools for ESXi hosts?
Dell’s iDRAC, HP’s ILO, and IBM’s RSA 2.
For enhanced performance, what is the RAM recommendation for ESXi hosts?
8 GB
