You are using a c5.large EC2 Instance with one 300GB EBS General purpose SSD volume to host a relational database. You noticed that the read/write capacity of the database needs to be increased. Which of the following approaches can help achieve this? Choose 2 answers from the options given below.

Answer options:

A.Use a larger EC2 Instance Type.
B.Enable Multi-AZ feature for the database.
C.Consider using Provisioned IOPS Volumes.
D.Put the database behind an Elastic Load Balancer.

Answer - A and C
The below snapshot from the AWS Documentation shows the different volume types and why Provisioned IOPS is the most ideal for this requirement.
Also, consider using a larger instance size for better processing capabilities based on EBS Bandwidth.
Option B is incorrect since the Multi-AZ feature is only for high availability.
Option D is incorrect since this would not alleviate the high number of read/write of the database.
