Your company is planning to set up a performance-sensitive workload in AWS. You need to set up the EC2 Instances for hosting this workload, and the EC2 volumes should be highly available. Which of the following are some of the ideal configurations that you should look for when setting up the EC2 Instance? Choose 2 answers from the options given below.

Answer options:

A.Ensure to choose an EBS Optimized Instance.
B.Ensure to choose an Instance store Instance type.
C.Ensure to choose an Instance type with 10 Gigabit network connectivity.
D.Ensure to use Cold HDD volumes.

Correct Answers: A and C
The AWS Documentation mentions the following.
Any performance-sensitive workloads that require minimal variability and dedicated Amazon EC2 to Amazon EBS traffic, such as production databases or business applications, should use volumes attached to an EBS-optimized instance or an instance with 10 Gigabit network connectivity. EC2 instances that do not meet this criterion offer no guarantee of network resources. The only way to ensure sustained reliable network bandwidth between your EC2 instance and your EBS volumes is to launch the EC2 instance as EBS-optimized or choose an instance type with 10 Gigabit network connectivity.
Option B is incorrect. The question requires that the volumes are highly available. Instance Store provides temporary block-level storage for the instances. So, this storage type is not suitable.
Option D is incorrect since this is used for archive storage for EC2 Instances.
