Explanation

Dedicated Host is the correct answer because:

• Hardware Isolation: Dedicated Host provides physical server isolation, ensuring the company's website runs on hardware that is not shared with other companies
• License Flexibility: Dedicated Host allows companies to use their existing per-socket, per-core software licenses, which is specifically mentioned in the requirements
• Compliance: Meets the requirement for dedicated hardware while maintaining existing licensing arrangements

Why other options are incorrect:

• Dedicated Instance: While this provides instance-level isolation, it doesn't guarantee the same level of hardware control for licensing purposes
• Reserved Instance: This is a billing option that provides cost savings but doesn't address hardware isolation or licensing requirements
• On-Demand Instance: This is a pay-as-you-go pricing model with no hardware isolation or licensing benefits

Dedicated Host is specifically designed for customers who need to meet compliance requirements, use existing software licenses, or have specific hardware isolation needs.
