    Hello AWSPro21,

    Thanks for the feedback.

    I understand how the given explanation can be confusing. To clarify, an ELB can work with a Spot Fleet even without an ASG. Both ASG and Spot Fleet use AWS Auto Scaling, where you can specify a minimum capacity to be maintained and a maximum capacity to scale up to. A key difference between the two is that AWS pretty much manages the instance lifecycle in a Spot Fleet. In contrast, with an ASG, you have some control over the lifecycle through lifecycle hooks.

    Just FYI, AWS recommends using EC2 Fleet instead of Spot Fleet. These two are practically similar in core functionalities, with Spot Fleet relying on legacy APIs. Nonetheless, we continue to use the term ‘Spot Fleet’ since it appears more frequently than ‘EC2 Fleet’ in the SA Pro certification exams.

    With all that said, we acknowledge there are some areas needing improvement, which we will address.

    Let me know if you have any further clarifications.
