Which cloud-based solution provides low-cost application hosting?
A systems administrator is looking for a low-cost application-hosting solution that is cloud-based. Which of the following meets these requirements?
Community Votes
100% of anonymous learners picked answer A. Votes are pick records left by other test-takers — they are not the verified answer.
Community Insight
The question tests knowledge of cloud hosting models, specifically the cost-efficiency of serverless frameworks; the common trap is confusing serverless with hypervisor or networking technologies.
A serverless framework offers a low-cost, cloud-based application hosting solution by charging only for actual compute usage without requiring dedicated server provisioning. Community consensus overwhelmingly confirms this as the correct choice for variable, scalable workloads.
Some candidates might choose Type 1 hypervisor, mistakenly associating 'hosting' with virtualization infrastructure, but hypervisors require dedicated server management and do not inherently provide low-cost cloud hosting.

Expert Analysis
Why the Answer Is Correct
A serverless framework is a cloud-based application-hosting model where developers deploy code without managing underlying servers. It operates on a pay-per-use pricing model, making it inherently low-cost since you only pay for actual execution time and resources consumed. This aligns perfectly with the requirement for a low-cost, cloud-based application-hosting solution.Why the Other Options Are Wrong
A Type 1 hypervisor is a bare-metal virtualization layer that requires dedicated physical hardware and ongoing management, contradicting both the 'low-cost' and 'cloud-based' criteria. SD-WAN (Software-Defined Wide Area Network) is a networking technology for optimizing WAN connectivity, not an application hosting platform. SDN (Software-Defined Networking) separates the control plane from the data plane for network management but does not provide application hosting capabilities.Community Comment Notes
All community comments unanimously support answer A, with 100% of votes. Commenters correctly emphasize that serverless computing eliminates infrastructure management overhead and charges based on actual usage, making it ideal for variable workloads. Multiple comments reinforce the distinction between serverless frameworks and traditional infrastructure options.Official Reference
Exam Strategy
When a question mentions 'low-cost' and 'cloud-based application hosting,' immediately think serverless or PaaS models. Eliminate options related to networking (SD-WAN, SDN) or on-premises virtualization (Type 1 hypervisor) as they do not fulfill cloud application hosting requirements.
