   A VxRail cluster will use vSAN erasure coding with a 4+1 configuration. The customer wants to know the minimum number of nodes required to support this configuration while maintaining the ability to tolerate a full node failure. What is the minimum node count?

   • A5 nodes
   • B8 nodes
   • C4 nodes
   • D6 nodes

   What is the primary implication of using replication (e.g., FTT=1) on storage capacity requirements in a VxRail cluster?

   • AIt reduces storage capacity requirements because of data compression.
   • BIt doubles the storage capacity required for the same amount of usable data.
   • CIt has no impact on storage capacity because copies are stored on the same disk.
   • DIt requires only a small amount of extra capacity for parity data.

   How does the choice of fault tolerance method (e.g., replication vs. erasure coding) affect the performance requirements of a VxRail cluster?

   • AFault tolerance methods have no impact on performance requirements.
   • BReplication always provides better performance than erasure coding in every scenario.
   • CErasure coding typically requires more CPU resources for encoding and decoding operations.
   • DErasure coding requires more memory than replication for caching.
