Your company is moving a large application to AWS using a set of EC2 instances.
A key requirement is reusing existing server-bound software licensing.
Which of the following options is the best for satisfying the requirement?
Click on the arrows to vote for the correct answer
A. B. C. D.Answer: C.
Option A is INCORRECT because despite instances run on a single-tenant hardware, AWS does not give visibility to sockets and cores required for reusing server bound licenses.
AWS highlights this in the comparison table at the following link:
https://aws.amazon.com/ec2/dedicated-hosts/Option B is INCORRECT because Reserved Instances are only a purchasing option and there's no way to control the hardware where these instances are running on.
Option C is CORRECT because instances run on a dedicated hardware where AWS gives visibility of physical characteristics.
AWS documentation mentions this with the following sentence:“...Dedicated Host gives you additional visibility and control over how instances are placed on a physical server, and you can consistently deploy your instances to the same physical server over time.
As a result, Dedicated Hosts enable you to use your existing server-bound software licenses and address corporate compliance and regulatory requirements.”
Option D is INCORRECT because Spot Instances are only a purchasing option.
Diagram: none.

AWS documentation explains the possibility of reusing server bound license:
https://aws.amazon.com/ec2/dedicated-hosts/The best option for reusing existing server-bound software licensing when moving a large application to AWS using a set of EC2 instances is EC2 Dedicated Hosts (option C).
EC2 Dedicated Hosts provide physical servers fully dedicated to your use, allowing you to use your existing server-bound software licenses. EC2 Dedicated Instances (option A) provide instances running on hardware dedicated to a single AWS account but still share the underlying physical hardware with other EC2 instances from other customers. EC2 Reserved Instances (option B) offer a discounted hourly rate but do not guarantee a dedicated host. EC2 Spot Instances (option D) allow you to bid for unused EC2 capacity and can be interrupted at any time, which is not a reliable option for running production workloads.
Therefore, EC2 Dedicated Hosts are the best option for satisfying the requirement of reusing existing server-bound software licensing when moving a large application to AWS using a set of EC2 instances.
