https://www.trek10.com/blog/dedicated-hosts-and-dedicated-instances/ While Dedicated Instances are extremely valuable from a compliance perspective, Dedicated Hosts also give you the visibility into the physical host that is required for a Bring Your Own License (BYOL) model — i.e., if you want to use your own Windows Server, SQL Server, SUSE, or RHEL licenses that are provided on a CPU core basis.

C. Dedicated Hosts A dedicated host is a physical EC2 server that is fully dedicated to your use, and on which you can run one or more Amazon EC2 instances. With dedicated hosts, you can use your existing Microsoft SQL Server licenses on Amazon EC2 instances. This allows you to bring your existing licenses and use them on EC2 instances, rather than purchasing new licenses. In addition, dedicated hosts offer added security, compliance and regulatory requirements. It is important to mention that Reserved Instances and Dedicated Instances also could be used in this scenario, however, the use of a dedicated host allows for more control over the underlying infrastructure, and in addition, it allows the company to have more visibility and control over their instances, which is beneficial when running databases that have high performance requirements.

What Is The Actual Physical Difference Between These Two "Dedicated” Offerings? The only real difference between the two is the hardware your instance uses, but when selecting a dedicated host, it provides greater control over the physical host than a shared host would provide. In other words, you could request a large M4 dedicated instance, and you may receive an instance exactly the same size as an M4 large, ### but when you reboot the instance, it may be rebalanced onto new hardware. ### Having multiple instances that overload the RAM may result in them being located on different computer hardware or even the same computer hardware. Answer C is valid.

Dedicated Hosts are physical servers with EC2 instance capacity that are dedicated to a specific AWS account. When using Dedicated Hosts, you have full control over the host, including the ability to bring your existing server-bound software licenses, such as Microsoft SQL Server, and run them on these dedicated instances. By using Dedicated Hosts, you can leverage your existing Microsoft SQL Server licenses and maintain compliance with licensing requirements while running your databases on EC2 instances in the AWS Cloud.

C. Dedicated Hosts

When licensing individual virtual machines (VMs), the SQL Server 2019 licensing guide states, “To license individual VMs using the Per Core model, customers must purchase a core license for each v-core (or virtual processor, virtual CPU, virtual thread) allocated to the VM, subject to a four-core license minimum per VM.”

When licensing individual virtual machines (VMs), the SQL Server 2019 licensing guide states, “To license individual VMs using the Per Core model, customers must purchase a core license for each v-core (or virtual processor, virtual CPU, virtual thread) allocated to the VM, subject to a four-core license minimum per VM.”

If you chose (A) or (C) you are correct. https://aws.amazon.com/windows/resources/licensing/ Your existing licenses may be used on AWS with Amazon EC2 Dedicated Hosts, Amazon EC2 Dedicated Instances, or EC2 instances with default tenancy using Microsoft License Mobility through Software Assurance.

Answer is C, There is defference btw dedicated host and dedicated instance. Bring Your Own License (BYOL) can be supported on dedicated host. But on dedicated instance it's partially supported. so answer is C.

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/dedicated-instance.html //* Microsoft SQL Server with License Mobility through Software Assurance, and Windows Virtual Desktop Access (VDA) licenses can be used with Dedicated Instance.//

Both A and C are correct but in the question there is no clue about cost efficiency so 100% correct answer is C.

Dedicated Host

C is the answer.

A. Dedicated instance is cheaper.

I don't see why dedicated host is better than dedicated instance. In the link from the site, it states that hosts are good. Shared tenancy is more complicated. Since dedicated hosts are cheaper than dedicated instance, hosts is my answer.

The answer is dedicated host. https://aws.amazon.com/windows/resources/licensing/
