Which of the following is NOT a cloud computing deployment model?

• Public Cloud

• Private Cloud

• Hybrid Cloud

• Distributed Cloud

Answer explanation

Distributed Cloud is an architecture, not a deployment model. The main cloud deployment models are Public, Private, and Hybrid.

What does "scalability" in cloud computing refer to?

• The ability to increase or decrease resources based on demand

• The ability to change cloud providers easily

• The ability to use cloud resources only during business hours

• The ability to physically move data centers

Answer explanation

Cloud resources scale up or down dynamically to meet demand.

Which cloud service model provides the highest level of control over the underlying infrastructure?

• Software as a Service (SaaS)

• Platform as a Service (PaaS)

• Infrastructure as a Service (IaaS)

• Function as a Service (FaaS)

Answer explanation

IaaS provides access to virtualized infrastructure like servers and networking, giving users maximum control.

In cloud computing, what is a Virtual Private Cloud (VPC)?

• A cloud-based network isolated within a public cloud

• A cloud model that is accessible only on private data centers

• A security tool used for encrypting cloud data

• A cloud provider that offers only networking services

Answer explanation

VPC allows users to create a private network within a public cloud environment.

What is the primary benefit of multi-tenancy in cloud computing?

• Reduces the need for user authentication

• Allows multiple users to share the same physical infrastructure securely

• Eliminates security concerns in the cloud

• Ensures dedicated hardware for each user

Answer explanation

Multi-tenancy optimizes resource usage while maintaining isolation between tenants.

Which of the following security risks is most commonly associated with cloud computing?

• Data breaches and unauthorized access

• Increased on-premise server costs

• Slow application performance

• Lack of internet access

Which cloud computing feature ensures that resources are only used when needed and released when not in use?

• Pay-as-you-go pricing

• High availability

• Data redundancy

• Load balancing

Explain how cloud computing enhances network security while also introducing new security challenges.

Answer explanation

Cloud computing enhances network security by implementing advanced security measures such as encryption, identity and access management (IAM), firewalls, and automated threat detection. Cloud providers also offer regular security updates and compliance with industry standards. However, cloud security also introduces challenges, such as data breaches, misconfigured settings, and shared responsibility concerns. If users do not properly configure access controls or encryption settings, unauthorized access and data leaks can occur.

Discuss the impact of cloud computing on data storage and management. How does it compare to traditional on-premise storage solutions?

Answer explanation

Cloud computing revolutionizes data storage and management by offering scalability, cost efficiency, and remote accessibility. Unlike traditional on-premise storage, where organizations must invest in and maintain hardware, cloud storage allows businesses to scale their data needs instantly without significant upfront investment. Additionally, cloud providers offer data redundancy and disaster recovery options. However, cloud storage also requires careful consideration of security, compliance, and vendor lock-in risks.

Which of the following is NOT a characteristic of the public cloud?

• Multi-tenancy

• Pay-as-you-go pricing

• Exclusive access to resources

• High scalability

Answer explanation

Public cloud resources are shared among multiple users.
