C.
erasure coding
D.
object replication
Answers
D.
object replication
Suggested answer: C, D

Explanation:

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.

C and D are correct because erasure coding and object replication are two StorageGRID features that provide data durability for large unstructured datasets. Erasure coding is a technique that splits an object into data fragments and parity fragments and distributes them across different nodes or sites. Object replication is a technique that creates multiple copies of an object and stores them on different nodes or sites. The other options are not features of StorageGRID or do not provide datadurability.
