Explanation
All four options correctly describe HBase because it is simultaneously column-oriented (data is stored and accessed by column families, not row-by-row), a NoSQL database (it uses a non-relational, schema-flexible model), and distributed (it runs on top of HDFS, spreading data across many nodes in a cluster). Additionally, at its core, every cell in HBase is addressed by a unique composite key - (row key + column family + column qualifier + timestamp) → value - making it fundamentally a key-value store.
Since this is an "all of the above" scenario, there are no wrong distractors to refute; the trap for exam takers is assuming these properties are mutually exclusive when in fact they describe different dimensions of the same system.
Memory tip: Think of HBase as "CNDK" - Columnar, NoSQL, Distributed, Key-Value. Or use the phrase "Can NoSQL Databases Keep values?" - each word maps to one property, and the answer is always yes for HBase.
