Question 92: I think is 256, 512 is only with 4 paths

Question 58: This setting is used when there is the desire or a requirement to specify an additional isolation address. The isolation address is used by a host which “believes” it is isolated. In other words, if a host isn’t receiving heartbeats anymore it pings the isolation address to validate if it still has network access or not. If it does still have network access (response from isolation address) then no action is taken, if the isolation address does not respond then the “isolation response” is triggered.

Question 54: Independent disks are not affected by snapshots.
Independent are written to disk permanently.

Question 78: Auto Deploy Stateless Caching – This feature allows you to cache the host's image locally and continue to provision the host with Auto Deploy.

Question 103: CHAP = Challenge-Handshake Authentication Protocol

Question 88: The opposite is correct:
should be these.
– vmware-vcha
– vmware-vmon

Question 85: Paravirtual RDMA (Remote direct memory access).

Question 53: MSCS = MicroSoft Cluster Server

Question 115: "on a disturbed switch"... who disturbed it? and how can we make sure the switch is no longer being disturbed?

Question 92: iSCSI Physical
LUNs per server - 512
Number of paths to a LUN (software iSCSI and hardware iSCSI) - 8

Question 88: https://imgur.com/a/zUr21

deployed a vCenter HA configuration to check this and the common running services in active, passive and witness nodes are the following:
– vmware-vcha
– vmware-vmon

Question 88: In my opion
Vmware-VCHA
Vmware-vMon

Question 85: Remote Direct Memory Access (RDMA) is a technology that allows computers in a network to exchange data in main memory without involving the processor, cache or operating system of either computer. Like locally based Direct Memory Access (DMA), RDMA improves throughput and performance because it frees up resources.

Question 84: In vSphere 6.5, you can use the vCenter Server Appliance Management Interface to create a file-based backup of the vCenter Server Appliance and Platform Services Controller appliance.

Question 59: HERE: %PROGRAMDATA%\VMware\vCenterServer\logs directory, usually C:\ProgramData\VMware\vCenterServer\logs
and HERE: %TEMP% directory, usually C:\Users\username\AppData\Local\Temp

The files in the %TEMP% directory include vminst.log, pkgmgr.log, pkgmgr-comp-msi.log, and vim-vcs-msi.log.

Question 25: Instant clones are very similar to linked clones in that they share a virtual disk of a parent VM and therefore consume less storage than a full VM. But, instant clones take it one step further by doing the same thing with memory. Instant clones are also created off a running VM instead of a powered off one. This provides better methods of management for provisioning, updates, and memory utilization.

Linked - share disk.
Instant - share disk AND RAM.

Question 27: Usage: esxcli storage core device set [cmd options]
