“What is upgrade to EC2”
The feature that allows customers to create a copy of their LightSail instance in EC2 is the LightSail-EC2 snapshot. This feature enables customers to migrate their LightSail instances to EC2 instances, which provides them with greater flexibility and scalability.
To use this feature, customers must create a snapshot of their LightSail instance, which is a backup of the instance's data at a specific point in time. They can then use the snapshot to create a new EC2 instance, which will be an exact copy of the LightSail instance, including all of its data and settings.
The LightSail-EC2 snapshot feature simplifies the migration process by eliminating the need to manually transfer data and settings between instances. Additionally, it allows customers to take advantage of the additional resources and capabilities offered by EC2, such as larger instance types, load balancing, and autoscaling.
In summary, the correct answer to the question is D. LightSail-EC2 snapshot.
