An architect will be taking over control of a former Linux server fleet and repurposing the hardware into a new vSphere cluster. The current environment is already connected to the network but the hosts do not have any local disks. Since the fleet hardware is uniform, the architect can use a single ESXi image. All hosts within the cluster have the same CPU and memory capacity.
Which ESXi deployment method should the architect use?
A

Both Stateless caching and Stateful Auto Deploy options store ESXi configuration or state on the host disk. Since no local disk available, Stateless Auto Deploy is the best option...
now I am thinking its B I"n stateless casched" the initial boot image and configuration are fetched from the Auto Deploy server and then cached on the ESXi host's local disk. "Stateless, no local storage is used," the host configuration is abstracted into a Host Profile and applied when the host connects to the appropriate vCenter/Cluster
The options needs corrections. Only Stateless caching or Stateful installs are possible options for AutoDeploy. From VMware ESXi Installation and Setup page 111 Stateless caching By default, Auto Deploy does not store ESXi configuration or state on the host disk. Instead, an image profile defines the image that the host is provisioned with, and other host attributes are managed through host profiles. A host that uses Auto Deploy for stateless caching still needs to connect to the Auto Deploy server and the vCenter Server. Stateful installs You can provision a host with Auto Deploy and set up the host to store the image to disk. On subsequent boots, the host boots from disk.
B as no local disks
The host has no local disk, which is necessary for all other options.
B Unlike stateless ESXi hosts, stateless caching requires a dedicated boot device to be assigned to the host.
A is correct, Two deployment modes are available. Stateless Caching and Stateful installs, this is a trick question.
The answer is B
D, can be the correct answer? Stateful vSphere Auto Deploy allows the architect to create a reference host with the necessary ESXi image and configuration, and then deploy this image and configuration to multiple hosts in the cluster. Since the hardware is uniform, a single ESXi image can be used for all hosts, and the stateful deployment method allows for quick and easy deployment without the need for manual installation on each host.
The Correct Answer is A Like @Alchot mentioned, Only Stateless caching or Stateful installs are possible options for AutoDeploy "You can use the System Cache Configuration host profile to provision hosts with vSphere Auto Deploy stateless caching and stateful installs." Taken from: https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.esxi.install.doc/GUID-C6FBA22C-048A-455F-9D45-58834445ACA5.html
Selected Answer: B Like @Alchot mentioned, Only Stateless caching or Stateful installs are possible options for AutoDeploy "You can use the System Cache Configuration host profile to provision hosts with vSphere Auto Deploy stateless caching and stateful installs."

I`m closer to "stateless" but I think this question doesn`t have a very meaningful answer as both "stateless" and "cached stateless" modes are possible. Auto Deploy modes Having completed the Auto Deploy installation procedure, let's walk-through the different modes you can use to configure vSphere Auto Deploy. There are three possible installation types you can use: Stateless: The ESXi image is not technically installed but it is loaded directly into the host's memory as it boots. Stateless caching: The image is cached on the local disk, remote disk, or USB. If the Auto Deploy server is not available, the host boots from the local cache. Stateful: The image is cached on the local disk, remote disk, or USB. As compared to stateless caching, the boot order is inverted; the host boots first from local disk then from the network. https://www.oreilly.com/library/view/mastering-vmware-vsphere/9781787286016/28754c90-98d5-4f29-9606-1f1c2e3e1b11.xhtml
A sounds right. The image cache can be on a remote disk Hosts provisioned with vSphere Auto Deploy cache the image (stateless caching) Set up and apply a host profile for stateless caching. You can cache the image on a local disk, a remote disk, or a USB drive. Continue provisioning this host with vSphere Auto Deploy. If the vSphere Auto Deploy server becomes unavailable, for example because hundreds of hosts attempt to access it simultaneously, the host boots from the cache. The host attempts to reach the vSphere Auto Deploy server after the boot operation to complete configuration.
Definately B, as no disks: https://www.oreilly.com/library/view/mastering-vmware-vsphere/9781787286016/28754c90-98d5-4f29-9606-1f1c2e3e1b11.xhtml
stateless is always with caching on Local Disk or USB Disk. i think the answer is C
Answer is wrong. Should be B. No local disk
