, Question 1 (Multiple Choice)
Case Study:
A multinational corporation is planning to migrate its critical enterprise
applications to a public cloud. Security and strict isolation between
workloads are top priorities. The IT team is evaluating the virtualization
techniques offered by various cloud providers.
Question:
Which virtualization technology provides the highest level of isolation for
sensitive enterprise data in a public cloud setting?
a) Linux containers
b) Serverless functions
c) Hypervisor‑based virtual machines
d) Sandbox environments
Correct ANS: c) Hypervisor‑based virtual machines
Rationale:
Hypervisor‑based VMs create fully isolated environments by abstracting
the hardware, ensuring that each tenant’s workload is secured from
others. This strong isolation is critical for sensitive applications, whereas
containers and serverless functions share underlying OS components that
may not offer the same level of security.

Question 2 (Fill in the Blank)
Case Study:
An e-commerce company is deploying both legacy systems and new
cloud services. To ensure business continuity and leverage scalability, the
company wants to maintain some applications on‑premises while
migrating other functions to the public cloud.

, Question:
Deployments that combine on‑premises infrastructure with public cloud
services are known as ______ clouds.
Correct ANS: hybrid
Rationale:
A hybrid cloud strategy integrates private (on‑premises) and public
clouds, offering scalability and flexibility while maintaining control over
sensitive data and legacy systems.

Question 3 (True/False)
Case Study:
A startup builds a microservice‑based application using a serverless
architecture to reduce operational overhead. They pay only for execution
time without provisioning or managing the underlying infrastructure.
Question:
True or False: In a serverless architecture, developers do not manage
server provisioning, and costs are incurred only during function
execution.
Correct ANS: True
Rationale:
Serverless computing abstracts infrastructure management away from
developers. Charges are based on the actual compute time (per
invocation), which means there is no cost for idle resources.

, Question 4 (Multiple Response)
Case Study:
A financial institution deploys a cloud‑based data analytics platform to
process large volumes of real‑time transaction data. The platform
integrates multiple data services to handle ingestion, processing, and
storage.
Question:
Select all that apply: Which cloud services are typically employed to build
a scalable, real‑time data analytics platform?
a) Infrastructure as a Service (IaaS)
b) Platform as a Service (PaaS)
c) Software as a Service (SaaS)
d) Function as a Service (FaaS)
e) Database as a Service (DBaaS)
Correct ANSs: b) Platform as a Service (PaaS), d) Function as a Service
(FaaS), e) Database as a Service (DBaaS)
Rationale:
PaaS provides managed services and development environments; FaaS
(serverless functions) supports event‑driven processing; and DBaaS offers
scalable database management. Although IaaS provides raw resources,
the question focuses on managed services that simplify real‑time
analytics.

Question 5 (Multiple Choice)
Case Study:
A cost‑sensitive enterprise is planning to migrate legacy applications to
the cloud. The IT team needs a dynamic resource allocation method to
optimize costs during varying workloads.
