Which two StorageGRID features provide data durability for large unstructured datasets?

1. Storage Grid ILM Rules provide only two mechanisms to protect object data from loss
   1. Replication
   2. Erasure Coding

   Storage Tiering makes the best use of a storage technology for each data class

   I choose A and C

2. B – does mean tiering between you StorageGRID and public S3 clouds
   C – does mean replication between nodes or datacenters or you geo sites

   A – erasure coding protect if you have many sites or datacenters, but not protect (durability for large unstructured datasets) if you have two datacenters

3. When you configure the Erasure Coding profile for an ILM rule, you select an available erasure coding scheme. Erasure coding schemes control how many data fragments and how many parity fragments are created for each object. The erasure coding schemes that are available depend on how many Storage Nodes and sites make up the storage pool you plan to use.

   so I choose AC
