Question 18
Domain 2: Design for New SolutionsWhich AWS feature best fits the description of a managed service offering in a cost optimization strategy for new solutions?
Correct answer: B
Explanation
Managed service offerings are AWS services where AWS operates and maintains the underlying infrastructure, reducing customer operational overhead as part of the solution design. — AWS-Certified-Solutions-Architect-Professional_Exam-Guide.txt
Why each option is right or wrong
A. A service where the customer provisions and maintains all servers manually
Managed services shift infrastructure operation and maintenance to AWS, not entirely to the customer.
B. A service where AWS manages the underlying infrastructure for the customer
The source material identifies managed services as AWS managed service offerings. In this question, the defining characteristic is that AWS manages the underlying infrastructure, which aligns directly with the concept of a managed service offering used in solution design.
C. A pricing model that only applies to services purchased with long-term contracts
Managed services describe who operates the service, not a contract-length pricing requirement.
D. A support plan that provides architectural guidance without running the workload
Managed services involve operating the service itself, not only providing advisory assistance.
