You are helping another team to create an AWS Aurora Database for a new application. The users of the application mainly come from Europe and North America. You propose to configure an Aurora Global Database. The primary database is located in eu-west-1 region, and the secondary database is located in us-east-1 region. Which benefits can this Amazon Aurora Global Database bring? (Select Three) 

Answer options:

A.The cluster in the secondary region us-east-1 enables low-latency reads.
B.Aurora Global Database is available for both Aurora MySQL and Aurora PostgreSQL.
C.The clusters in both primary and secondary regions have the same read & write configured capacities.
D.There is no charge for the replicated write I/Os between the primary region and each secondary region.
E.For disaster recovery, the secondary cluster can be easily promoted to allow full read and write operations.

Correct Answer – A, B and E
Refer to https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-global-database.html for the descriptions of Aurora Global Database.
To create a global database, select “Global” in the below screenshot:
Option A is CORRECT: Because the database in the secondary AWS Region has provided read-only services to users. There is no write for the secondary region.
Option B is CORRECT: Because 
Aurora Global Database is only available for the following versions:
Aurora with MySQL 5.6 or 5.7 compatibility.
Aurora with PostgreSQL 10.11 compatibility.
Refer link: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/aurora-global-database.html
Option C is incorrect: Because there is no write capacity for the secondary region.
Option D is incorrect: Because users still need to pay for the replicated write data between the primary region and each secondary region, although the charge is small. Please refer to https://aws.amazon.com/rds/aurora/global-database/ for its pricing.
Option E is CORRECT: This is one major benefit of a global database. When required, the database in the secondary AWS Region can be promoted to take full workloads within a minute.
