A company uses a single ECS site with a 6+3 erasure coding scheme. They want to ensure that a single disk failure does not cause data loss while minimizing storage overhead. What should they do?

Decrease the number of parity chunks

Enable synchronous replication to another site

Keep the current erasure coding scheme

Increase the number of data chunks in the erasure coding scheme

A company has a federation with three sites. They want to ensure that data is replicated to at least two other sites, but they also want to minimize the amount of data transferred over the WAN. Which replication strategy should they use?

Replicate to one site and use erasure coding across the federation

Synchronous replication to one site and asynchronous to the other

Asynchronous replication to both sites

An administrator is explaining how ECS stores data. They say that an object is split into chunks, and chunks are then grouped into segments. What is the primary benefit of this packaging?

It reduces the number of metadata entries

It allows objects to be stored on a single disk

It enables deduplication and compression at the chunk level

It simplifies the object namespace

What is the primary purpose of erasure coding in ECS?

To reduce storage overhead while providing data protection

To speed up data access for frequently read objects

To create point-in-time copies of data
