2026/2027) Questions And Verified
Answers | 100% Correct | Grade A.
1. A company wants to migrate a web application to the cloud while
minimizing infrastructure management. Which cloud service
model is the best choice?
A. Infrastructure as a Service (IaaS)
B. Platform as a Service (PaaS)
C. Software as a Service (SaaS)
D. Bare-metal hosting
Rationale: PaaS provides a managed platform where developers deploy
applications without managing operating systems, servers, or runtime
environments. This allows organizations to focus on application
development rather than infrastructure administration.
2. Which cloud deployment model provides infrastructure dedicated
to a single organization?
A. Public cloud
B. Community cloud
,C. Private cloud
D. Hybrid cloud
Rationale: Private clouds are designed for exclusive use by one
organization, offering greater control, customization, and security than
shared public cloud environments.
3. Which characteristic of cloud computing allows organizations to
rapidly provision computing resources when demand increases?
A. Fault tolerance
B. Resource pooling
C. Rapid elasticity
D. Virtualization
Rationale: Rapid elasticity enables cloud resources to automatically
scale up or down based on workload demands, allowing businesses to
efficiently handle fluctuating traffic.
4. What is the primary benefit of auto scaling?
A. Reducing storage capacity
B. Eliminating encryption requirements
C. Automatically adjusting resources based on workload demand
D. Preventing network latency
Rationale: Auto scaling helps optimize cost and performance by adding
or removing compute resources as application demand changes,
ensuring efficient resource utilization.
, 5. Which storage type is best suited for virtual machine boot disks?
A. Object storage
B. Archive storage
C. File storage
D. Block storage
Rationale: Block storage provides low-latency, high-performance
storage that is ideal for operating systems, databases, and virtual
machine disks.
6. Which cloud service is designed primarily for storing unstructured
data such as images, videos, and backups?
A. Block storage
B. Database storage
C. Object storage
D. Temporary storage
Rationale: Object storage stores files as objects with metadata, making
it highly scalable and ideal for media files, backups, and archival data.
7. Which networking component filters inbound and outbound
traffic using predefined rules?
A. Load balancer
B. VPN gateway
C. DNS server
D. Firewall
, Rationale: Firewalls inspect and control network traffic according to
security policies, helping prevent unauthorized access to cloud
resources.
8. What is the primary purpose of a load balancer?
A. Encrypt stored data
B. Compress application files
C. Distribute incoming traffic across multiple servers
D. Monitor database performance
Rationale: Load balancers improve application availability and
performance by distributing client requests across multiple backend
servers.
9. Which cloud architecture principle improves application
availability by deploying resources across multiple availability
zones?
A. Compression
B. Replication delay
C. High availability
D. Single-region deployment
Rationale: High availability ensures applications remain operational
despite failures by distributing workloads across redundant
infrastructure.
