   What is the purpose of fault domains in a vSAN ESA cluster design?

   • ATo improve performance by placing data closer to the VMs
   • BTo protect against failures that affect multiple hosts at once, such as a rack failure
   • CTo isolate storage traffic from VM traffic
   • DTo group hosts that share the same hardware configuration

   Which of the following is a key design difference between vSAN ESA and OSA?

   • AESA uses a separate storage network, while OSA uses the same network as VM traffic
   • BESA uses a single disk group per host, while OSA can use multiple disk groups
   • CESA requires a separate witness host for stretched clusters, while OSA does not
   • DESA supports only all-flash configurations, while OSA supports hybrid configurations

   A company is comparing vSAN ESA with OSA for a new virtual desktop infrastructure (VDI) environment. The VDI team expects high read IOPS and low latency, but the storage capacity requirement is moderate. The current OSA design uses a mix of cache and capacity tiers. Which design consideration is unique to ESA and should be factored into the comparison?

   • AESA still requires a dedicated cache tier, but it uses NVMe for both cache and capacity, doubling the number of drives needed.
   • BESA requires all-flash hardware, but it does not use a separate cache tier; instead, all NVMe devices participate in the storage pool, simplifying capacity planning.
   • CESA has the same hardware requirements as OSA but offers better performance due to software optimizations.
   • DESA only supports SATA SSDs, so it cannot achieve the same IOPS as OSA with NVMe.
