Question 4: Which of the following statement is correct with regards to Amazon Aurora database?

  1. Amazon Aurora replicates each chunk of my database volume six ways across three Availability Zones
  2. Whatever, storage you provision for Aurora database, you will be charged 3 times of that.
  3. Amazon Aurora supports both MySQL and PostgreSQL
  4. 1, 3
  5. 1, 2, 3


Correct Answer: 4

Exp: Amazon Aurora is a relational database engine that combines the speed and reliability of high-end commercial databases with the simplicity and cost-effectiveness of open source databases.

Amazon Aurora MySQL delivers up to five times the performance of MySQL without requiring any changes to most MySQL applications, similarly Amazon Aurora PostgreSQL delivers up to three times the performance of PostgreSQL. Amazon RDS manages your Amazon Aurora databases, handling time-consuming tasks such as provisioning, patching, and backup, recovery, failure detection and repair. You pay a simple monthly charge for each Amazon Aurora database instance you use. There are no upfront costs or long-term commitments required.

Amazon Aurora replicates each chunk of data volume six times across 3 availability zones, but AWS will not charge you for 6 copies. It will charge you only for one copy of data.
