   When choosing between RAID 5 and RAID 6 for a VxRail node's local storage, what is the primary trade-off?

   • ARAID 6 provides higher fault tolerance but uses more capacity for parity and may have lower write performance.
   • BRAID 6 is always faster than RAID 5 because of additional parity.
   • CRAID 5 and RAID 6 have identical capacity and performance characteristics.
   • DRAID 5 provides higher fault tolerance but uses more capacity than RAID 6.

   A VxRail cluster is being designed with vSAN erasure coding. The customer wants to minimize the number of nodes while still tolerating a single node failure. Which erasure coding configuration should be used?

   • A4+1 erasure coding
   • B8+2 erasure coding
   • C2+1 erasure coding
   • D6+2 erasure coding

   A VxRail cluster is being deployed across two racks in a data center. The customer requires that the cluster remain available if an entire rack loses power. Which fault domain configuration should be used?

   • AA single fault domain containing all nodes
   • BNo fault domains, relying on RAID
   • CFour fault domains, splitting each rack into two
   • DTwo fault domains, each containing one rack's nodes

   In a vSAN cluster using erasure coding with a RAID 5 (4+1) configuration, what does the '4+1' indicate?

   • AFour parity components and one data component are used, providing high resilience.
   • BFour data components and one parity component are used to protect against a single failure.
   • CThe cluster can tolerate four simultaneous node failures.
   • DThe cluster requires four nodes and one witness node to function.
