Which components in the Fusioninsight HD platform support table and column encryption? (Multiple choice)

Question

Options

• AFlink
• BHBase
• CHive
• DHDFS

• B

Explanation

In FusionInsight HD, HBase and Hive are storage-layer components that manage structured data in tables and columns, which is why they natively support table and column-level encryption - HBase encrypts at the column family level, while Hive supports transparent encryption of table data and specific columns through its security framework.

Flink (A) is incorrect because it is a stream processing engine, not a data storage system; it processes data in flight but does not own or encrypt tables or columns at rest. HDFS (D) is incorrect because its encryption operates at the file and directory level via encryption zones - it has no concept of tables or columns, making it a lower-level encryption mechanism than what the question describes.

Memory tip: Think "structured storage = column encryption." HBase and Hive both store and manage structured, tabular data, so they can encrypt at the table/column granularity. Flink is a processor, and HDFS is a file system - neither organizes data into tables natively.
