a) Platform as a Service (PaaS)
b) Infrastructure as a Service (IaaS)
c) Software as a Service (SaaS)
d) Function as a Service (FaaS)
Rationale: IaaS provides virtualized computing resources over the internet. PaaS
provides platforms, SaaS delivers software, FaaS runs code.
Q2. A student wants to pay only for the exact number of minutes their application
runs on a server. Which pricing model is this?
a) Reserved Instances
b) Spot Instances
c) Pay-as-you-go
d) Savings Plans
,Rationale: Pay-as-you-go (on-demand) ensures no upfront cost and you pay per
second/minute/hour of usage.
Q3. Which design principle of the AWS Well-Architected Framework suggests
adding more resources to handle increased load without downtime?
a) Elasticity
b) Scalability (vertical)
c) Disaster Recovery
d) Security
Rationale: Elasticity is the ability to scale resources up/down automatically based
on demand.
Q4. A company moves from a fixed monthly cost for servers to a variable cost
based on actual usage. What benefit is this?
a) Reduced time-to-market
b) Trade capital expense for variable expense

Rationale: Lambda runs code for events; no provisioning needed.
Q9. In 2026, which new AWS Well-Architected pillar was formally introduced
alongside Sustainability?
a) Generative AI Excellence

c) Quantum Readiness
d) Edge Optimization
Rationale: AWS updated pillars to include FinOps for cloud financial
management.
Q10. Which cloud deployment model is a mix of on-premises and public cloud?
a) Community cloud
