Which of the following solutions is not supported by DynamoDB?

A.
Hash secondary index

B.
Local secondary index

C.
Hash Primary Key

D.
Global secondary index

Explanation:
In DynamoDB, a secondary index is a data structure that contains a subset of attributes from a table, along with an
alternate key to support Query operations. DynamoDB supports the following two types of secondary indexes:
– Local secondary index is an index that has the same hash key as the table, but a different range key. A local secondary
index is “local” in the sense that every partition of a local secondary index is scoped to a table partition that has the same
hash key.
– Global secondary index is an index with a hash and range key that can be different from those on the table. A global
secondary index is considered “global” because queries on the index can span all of the data in a table, across all
partitions.
