What does an ESXi host require?

Back 1

○ 64 bit x86 CPU ○ 2 Cores ○ 4 GB RAM ○ GB NIC or 10 GB ○ Disk controller ○ Boot device with at least 1 GB in size ○ Processor must contain only LAHF (Load AH from Flags) and SAHF (Store HF into flags) instructions

Front 2

What are the three modes of auto deploy?

Back 2

○ Stateless - Auto deploy stores no ESXi state on the ESXi host disk and allows diskless configurations ○ Stateless Caching - ESXi image loaded into memory is also cached to a dedicated boot disk (Local, SAN, USB) in case the host cannot boot due to a problem with either PXE environemnt or auto deploy server ○ Stateful install - Auto deploy is usd as a provisning tool and a onetime PXE boot occurs but subsequent reboots will take place from a dedicated boot device

Front 3

What is lockdown mode?

Back 9

When you enable lockdown mode, no users other than vpxuser have authentication permissions, nor can they perform operations against the host directly. Lockdown mode forces all operations to be performed through vCenter Server. When a host is in lockdown mode, you cannot run vCLI commands from an administration server, from a script, or from vMA against the host. External software or management tools might not be able to retrieve or modify information from the ESXi host. Lockdown mode will not stop services from running, only being accessed

Describe the types of disk provisioning:

Back 30

Thick Provisioned Lazy Zeroed: Space required for the virtual disk is allocated during creation. Data remaining on the physical device is not erased during creation, but is zeroed out on demand at a later time on first write from the virtual machine. This is the default disk type.Thick Provision Eager Zeroed: Space required for the virtual disk is allocated during creation. Data remaining on the physical device is zeroed out when the disk is created. If you select this check box, this virtual machine can take advantage of VMware vSphere® Fault Tolerance.Thin Provision: A thin-provisioned disk uses only as much datastore space as the disk initially needs. If the thin disk needs more space later, it can expand to the maximum capacity allocated to it.
