   A VxRail architect is explaining fault tolerance methods to a customer. Which statement correctly describes the general purpose of RAID, erasure coding, and replication in a VxRail cluster?

   • AThey are interchangeable methods that provide identical fault tolerance and performance characteristics in all VxRail configurations.
   • BThey are used exclusively for backup and disaster recovery, not for protecting against local hardware failures.
   • CThey are only applicable to storage performance optimization, not to data availability.
   • DThey all provide data redundancy to protect against component or node failures, but they operate at different levels and with different overheads.

   A VxRail cluster is being designed for a workload that requires high performance and can tolerate a single drive failure. The customer is concerned about write performance. Which fault tolerance method should be recommended?

   • AErasure coding 4+1
   • BRAID 10
   • CRAID 5
   • DRAID 6

   A VxRail design must protect against a single drive failure while maximizing usable capacity. The customer is willing to accept a slight performance impact. Which RAID level should be selected?

   • ARAID 10
   • BRAID 5
   • CRAID 6
   • DRAID 1

   When designing a VxRail cluster with rack awareness, what is a critical requirement for node placement?

   • AEach fault domain must contain at least one copy of each data object.
   • BNodes must be placed in different racks but can be in the same fault domain.
   • CAll nodes must be placed in the same rack to simplify cabling.
   • DFault domains are only used for stretched clusters, not standard clusters.

   What is the purpose of configuring fault domains (e.g., rack awareness) in a VxRail cluster?

   • ATo improve network performance by grouping nodes in the same rack.
   • BTo reduce the number of nodes required in the cluster.
   • CTo ensure that data copies are placed in different racks, protecting against a rack-level failure.
   • DTo enable the use of erasure coding instead of replication.
