PREPARATION QUESTIONS WITH
VERIFIED ANSWERS 2026/2027.
1. A company needs to implement a system that automatically increases the number of
running instances during peak traffic and decreases them during low traffic. Which cloud
concept does this represent?
A. Elasticity
B. Fault Tolerance
C. High Availability
D. Agility
Answer: A
Conceptual Explanation: Elasticity refers to the ability to scale resources both up and
down dynamically based on demand, which is the specific focus of the scenario.
2. Under the Shared Responsibility Model, which of the following is typically the sole
responsibility of the cloud service provider in an IaaS environment?
A. Physical security of the data center
B. Operating system patching
,C. Network traffic encryption
D. Identity and access management
Answer: A
Conceptual Explanation: In IaaS, the provider manages the physical infrastructure, while
the customer is responsible for the OS, data, and applications.
3. Which cloud deployment model is most appropriate for a government agency that requires
exclusive access to the underlying hardware for security and regulatory compliance?
A. Public Cloud
B. Hybrid Cloud
C. Private Cloud
D. Community Cloud
Answer: C
Conceptual Explanation: Private clouds are dedicated to a single organization, providing
the highest level of control and isolation for regulatory requirements.
4. A developer wants to deploy a web application without managing any underlying servers
or operating systems. Which service model should they choose?
A. IaaS
B. PaaS
C. DaaS
, D. CaaS
Answer: B
Conceptual Explanation: Platform as a Service (PaaS) provides a framework for

5. What is the primary difference between a Region and an Availability Zone (AZ) in a major
cloud provider’s infrastructure?
A. A Region consists of multiple isolated locations called AZs.
B. An AZ consists of multiple Regions.
C. Regions are used for storage, while AZs are used for compute.
D. Regions and AZs are identical terms.
Answer: A
Conceptual Explanation: A Region is a geographic area that contains two or more
Availability Zones, which are isolated data centers designed for high availability.
6. Which technology allows for multiple isolated user-space instances to run on a single host
OS kernel, offering faster startup times than Virtual Machines?
A. Containers
B. Type 1 Hypervisor
C. Serverless Computing
