A vSAN administrator has a group of requirements from the application team, which mandates spreading the components across storage devices as much as possible.
What should the vSAN Administrator consider to achieve such a requirement for building a new vSAN cluster? (Choose two.)
To achieve the requirement of spreading components across storage devices as much as possible in a vSAN cluster, the vSAN Administrator should consider configuring disk striping. Disk striping in both OSA (Original Storage Architecture) and ESA (Erasure Coding Storage Architecture) helps distribute data across multiple disks, thereby achieving the objective of spreading components. Enabling deduplication, force provisioning, or creating a dedicated storage pool do not directly contribute to spreading components across storage devices.
It should be "A" and "B". Disk striping spread the components and it works in both OSA and ESA architectures. The "D" answer is wrong because deduplication just saves space by reducing the identical data blocks, it doesn´t "reduce" or "spread" the number of components.
are the questions still valid?
AD seems the correct answer because striping and deduplication gives the best result. Here we need to choose the most appropriate answer from the options.
A & B : configuring disk striping allows to spread the components on more hosts. C : is used to force the provisioning of a VM even if the storage policy cannot be compliant D : deduplication is a space efficiency method E : there is one storage pool per host. Not more, not less. It is an inner mecanism of vSAN ESA, and cannot be managed by the administrator.
Options B, C, and D are not directly related to achieving the goal of spreading components across storage devices in a vSAN cluster. Option B (Configure disk striping in ESA) is not a common vSAN configuration, and option C (Enable Force Provisioning in OSA) is not related to spreading components across storage devices. Option D (Enable deduplication for vSAN) might help reduce storage consumption, but it does not directly address the distribution of components across storage devices. So, the most appropriate choices to achieve the requirement are A and E.

Striping is wrong: https://core.vmware.com/blog/stripe-width-storage-policy-rule-vsan-esa "If it is no longer relevant for the ESA, then why does the policy rule still exist? Storage policies and the rules that make up a storage policy are a construct of the vCenter Server. A given vCenter Server may be responsible for many vSAN clusters, some of which may be running the OSA, while others use the ESA. Keeping these policy rules available across all cluster types can help maintain the compatibility of different cluster types and conditions."
A. Configure disk striping in OSA B. Configure disk striping in ESA Disk striping (option A and option B) can help to spread the data of an object across multiple physical drives. Object space reservation (OSA) and Erasure coding storage policy (ESA) can both be configured to use a stripe width greater than 1, which allows vSAN to stripe an object across multiple physical disks according to the defined stripe width.
A and E is correct answer.
I think AB is the correct answer
