Cloud database for RDS can support four database engines: MySQL, PostgreSQL, Oracle and Microsoft SQL Server.

Question

Options

• ATrue
• BFalse

• A
  77% (23)
• B
  23% (7)

Explanation

Option A is marked correct because Amazon RDS does support all four of the listed database engines -- MySQL, PostgreSQL, Oracle, and Microsoft SQL Server -- making the statement accurate in that those engines are available on the platform. Option B is wrong because it would imply RDS does not support these engines, which contradicts how the service actually works. However, it is worth noting that the statement is slightly misleading: RDS supports more than just these four engines, as MariaDB and Amazon Aurora are also available, so a stricter reading of "only four" would make the answer False -- be aware of how your specific exam frames the question.

Memory tip: Think of the four listed engines as the "legacy big four" relational databases that existed before cloud was mainstream -- MySQL, PostgreSQL, Oracle, and SQL Server -- and remember AWS added MariaDB and Aurora on top of them when building RDS.
