Question 1

Which Nutanix storage feature automatically moves data between SSD and HDD tiers based on access patterns?

Accepted Answer

Intelligent Tiering (ILM)

Answer

Nutanix Intelligent Lifecycle Management (ILM) automatically promotes and demotes data between storage tiers based on how frequently it is accessed.

Question 2

What is the default replication factor (RF) in a Nutanix cluster that protects against a single node failure?

Accepted Answer

RF2

Answer

RF2 stores two copies of data across different nodes, providing tolerance for a single node or disk failure while balancing storage efficiency.

Question 3

Which Nutanix data efficiency feature eliminates redundant data blocks across a storage container?

Accepted Answer

Deduplication

Answer

Deduplication identifies and removes identical data blocks, storing only a single instance and replacing duplicates with pointers to reduce storage consumption.

Question 4

In Nutanix AOS, what is a Storage Container?

Accepted Answer

A logical storage policy grouping that maps to a datastore

Answer

A Storage Container is a logical grouping within a storage pool that allows administrators to apply storage policies (compression, deduplication, RF) and presents as a datastore to hypervisors.

Question 5

Which Nutanix feature reduces storage space by encoding data with parity, tolerating failures with less overhead than full replication?

Accepted Answer

Erasure Coding (EC-X)

Answer

Erasure Coding (EC-X) stripes data with parity information across nodes, providing fault tolerance at a lower storage overhead than RF2 or RF3 for cold data.
