You are planning to host a general purpose workload application in AWS. You want to set up a cost-effective Instance type with the ability to be flexible for spikes in application usage. Which of the following can be used to implement this requirement? Choose 2 answers from the options given below.

Answer options:

A.Configure a t2.micro instance.
B.Configure an c4.large instance.
C.Configure burstable performance on the instance.
D.Configure the t2 unlimited option.

Correct Answers: A and D
The AWS Documentation mentions the following.
T2 Unlimited is a configuration option for T2 instances that can be set at launch or enabled at any time for a running or stopped T2 instance.
T2 Unlimited instances can burst above the baseline for as long as required. This enables you to enjoy the low T2 instance at an hourly price for a wide variety of general-purpose applications and ensures that your instances are never held to the baseline performance. The basic T2 hourly instance price automatically covers all CPU usage spikes if the average CPU utilization of a T2 Unlimited instance over a rolling 24-hour period is at or below the baseline. For a vast majority of general-purpose workloads, T2 Unlimited instances provide ample performance without any additional charges.
Option B is incorrect since this will not be a cost-effective option.
Option C is incorrect since this is not a configurable option.
