, Question 1:
A company is looking to improve the utilization of its physical servers by
running multiple operating systems on a single hardware platform.
Which technology makes this possible?
- A. Cloud Computing
- B. Virtualization
- C. Containerization
- D. High Availability Clustering
Correct ANS: B. Virtualization
Rationale:
Virtualization allows one physical server to be partitioned into multiple
virtual machines, each running its own operating system. This maximizes
resource utilization and reduces hardware costs while maintaining
isolation between environments.
---
Question 2:
In the context of cloud service models, which option describes
Infrastructure as a Service (IaaS)?
- A. Provisioning software applications on demand
- B. Offering a complete platform for application development
- C. Delivering virtualized computing resources over the Internet
- D. Licensing pre-installed software with limited customization
Correct ANS: C. Delivering virtualized computing resources over the
Internet
Rationale:
IaaS provides virtualized computing resources such as servers, storage,
and networking in a pay-as-you-go model. Unlike SaaS or PaaS, IaaS gives
customers control over the operating system and deployed applications.

, Question 3:
Which scheduling algorithm in modern operating systems is notable for
employing multiple queues with different priorities for enhanced process
management?
- A. First-Come, First-Served
- B. Round-Robin Scheduling
- C. Multi-Level Queue Scheduling
- D. Shortest Job Next
Correct ANS: C. Multi-Level Queue Scheduling
Rationale:
Multi-Level Queue Scheduling partitions the ready queue into multiple
queues based on process priority or characteristics. This approach helps
optimize CPU scheduling by treating different classes of processes with
policy-specific queues.
---
Question 4:
In distributed computing, what mechanism is primarily used to achieve
fault tolerance and high availability through data redundancy?
- A. Load balancing
- B. Data replication
- C. Data sharding
- D. Caching
Correct ANS: B. Data replication
Rationale:
Data replication involves creating multiple copies of data across different
servers or nodes, ensuring that if one copy becomes unavailable, another
can be accessed. This redundancy is central to fault tolerance and high
availability.

, Question 5:
Which security model asserts that no device or user should be trusted by
default—even if inside the organization’s perimeter—and requires
continuous verification?
- A. Perimeter Security Model
- B. Defense in Depth
- C. Zero Trust Architecture
- D. Role-Based Access Control
Correct ANS: C. Zero Trust Architecture
Rationale:
Zero Trust Architecture eliminates assumptions about internal trust. It
mandates verification for every access request, regardless of network
location, to mitigate risks arising from lateral movement by attackers.
---
Question 6:
Which technology encapsulates computer resources—such as software
applications and dependencies—in isolated environments for enhanced
portability and consistency?
- A. Virtualization
- B. Containerization
- C. Hyperconvergence
- D. Sandboxing
Correct ANS: B. Containerization
Rationale:
Containerization packages applications along with their libraries,
dependencies, and configurations into lightweight, portable containers.
This ensures consistency across development, testing, and production
environments without the overhead of full virtualization.
