Which of the following are characteristics of a reserved instance? (Choose three.)
A.
It can be migrated across Availability Zones
B.
It is specific to an Amazon Machine Image (AMI)
C.
It can be applied to instances launched by Auto Scaling
D.
It is specific to an instance Type
E.
It can be used to lower Total Cost of Ownership (TCO) of a system
Explanation:
You can use Auto Scaling or other AWS services to launch the On-Demand instances that use your Reserved
Instance benefits. For information about launching On-Demand instances, see Launch Your Instance. For
information about launching instances using Auto Scaling, see the Auto Scaling User Guide. http://

I’m not sure about this one.
It is NOT B, that leaves 4 possible answers and we need 3.
A and E are true.
C is tricky, you use on demand but if you got unused reserved those cover up.
D, when you reserve an instance, you specify an instance type, so for me D is true.
AED for me, but I buy AEC also.

It depends on the offering class.

The FAMILY is always a constant, but not necessarily the type.
