Exam 1Y0-403 topic 1 question 23 discussion

A and B are correct. Thin provisioning is not available on all hypervisors. C is not relevant D is wrong coz requires high write (Not read) as diff and ID disks are written at boot up. E thin provisioning, as it implies "thin" means less storage.

A + B A is a sneaky one as Citrix only support certain Hypervisors (Citrix, Vmware, Nutanix, MS)

A: We can configure a Machine Catalog to use RAM to optimize the temporary writes (similar to the Citrix Provisioning option “write cache in memory with offload to disk”). This feature is available for all thin cloned MCS machines, regardless of whether they are hosted on Citrix Hypervisor, Hyper-V or vSphere B: "All components can be placed on shared storage. This facilitates the sharing of the master image among multiple hypervisor hosts; however, the presence of the differencing disks will put more strain on the shared storage array because it is hosting temporary data."

A&B is correct

with voting: From the original courseware: "A differencing disk is attached to each VM to capture all write I/O activity." and "However, keep in mind the increased read I/O requirements, since machines will sometimes need to read from the master image as well as the differencing disk.". So B+D should be the right answers. (.... vs. Citrix IntelliCache !!!!)

From the courseware: "All components can be placed on shared storage. This facilitates the sharing of the master image among multiple hypervisor hosts; however, the presence of the differencing disks will put more strain on the shared storage array because it is hosting temporary data." Since differencing disks require write functions, B is likely one of the answers. C is not correct. NFS is "preferred" but not the limitation. "Thin / Thick provisioning: NFS storage is preferred due to the thin provisioning capabilities." https://docs.citrix.com/en-us/citrix-virtual-apps-desktops/1912-ltsr/install-configure/machine-catalogs-create.html E is not right because this model uses NO storage on the hosts. A doesn't seem right. AFAIK thin provisioning and shared storage can be used anywhere. Is the second choice D? It sounds sort of right. There is a lot of writing AND reading going on during machine creation and updates.

B and E
