Final answer:
Dedicated hosts are dedicated to a single customer, and EC2 instances running on such hosts incur charges. Contrary to misconceptions, there is a charge for running EC2 instances on a dedicated host, and the host is not shared with a small group.
Step-by-step explanation:
The question pertains to dedicated hosts, which are a feature available in cloud computing platforms such as Amazon Web Services (AWS). When using dedicated hosts, users are billed based on two main factors:
- The fact that the host is dedicated to a single customer, meaning only that customer's instances run on the host.
- EC2 instances that are running on the dedicated host incur charges according to the compute capacity consumed. You're not charged for instances that are not running.
Thus, the two true statements about dedicated hosts would be that the host is dedicated to you and that EC2 instances incur a charge while running on the dedicated host. It is incorrect to say that there's no charge for EC2 instances running on a dedicated host, as usage charges apply. Similarly, it is incorrect to state that the host is dedicated to a small group of customers; the entire premise of a dedicated host is that the physical server is allocated to a single customer for their exclusive use.
