, Multiple Choice Questions
Question 1:
A company migrating its data analytics workloads to the cloud wants to
benefit from a model where resources can be rapidly allocated and de‐
allocated based on demand. Which feature of cloud computing does this
scenario illustrate?
A. Resource pooling
B. Elasticity
C. Multi-tenancy
D. On‑demand self-service
Correct ANS: B. Elasticity
Rationale:
Elasticity—the ability to quickly scale resources up or down as workload
demands change—is one of the hallmark benefits of cloud computing. It
minimizes costs and ensures that performance adapts dynamically to
usage spikes.

Question 2:
A data analytics team deploys a solution using a cloud provider’s
managed services to reduce operational overhead and speed up
development. Which cloud service model best matches this approach?
A. Infrastructure as a Service (IaaS)
B. Platform as a Service (PaaS)
C. Software as a Service (SaaS)
D. Container as a Service (CaaS)
Correct ANS: B. Platform as a Service (PaaS)
Rationale:
PaaS provides a complete development and deployment environment

, managed by the cloud provider. This allows the team to focus on coding
and analytics without having to manage the underlying hardware or
middleware.

Question 3:
To ensure high availability and fault tolerance, a cloud architecture is
designed to replicate applications and data across multiple geographical
regions and availability zones. This approach is best described as:
A. Load balancing
B. Geo-redundancy
C. Vertical scaling
D. Container orchestration
Correct ANS: B. Geo‑redundancy
Rationale:
Geo-redundancy involves replicating data and services across different
geographical regions (or availability zones) to prevent service disruption
if one location fails, ensuring continuous availability.

Question 4:
A cloud provider offers a managed container orchestration service that
automatically manages scaling, load balancing, and self-healing of
applications. Which technology underpins this service?
A. Docker Swarm
B. Kubernetes
C. Mesos
D. Apache Marathon
Correct ANS: B. Kubernetes
Rationale:
Kubernetes is the industry-standard system for automating the
