A company wants to deploy a set of Instances. The workloads on these instances remain fairly constant in CPU utilization with brief intervals of burstable performance. Which of the following would be the most Cost-effective instance types to be used for the Instances? Select 2 correct answers from the following options.

Answer options:

A.T2 Instance type
B.M4 Instance type
C.C4 Instance type
D.T3 Instance type

Correct Answers: A and D
The AWS Documentation mentions the following.
Burstable performance instances, which include T3 and T2 instances, are designed to provide a baseline level of CPU performance with the ability to burst to a higher level when required by your workload. Burstable performance instances are well suited for a wide range of general-purpose applications. Examples include microservices, low-latency interactive applications, small and medium databases, virtual desktops, development, build, and stage environments, code repositories, and product prototypes.
Because this is clearly mentioned in the AWS documentation, all other options are invalid.
