Explanation: Fault tolerance ensures that a cloud system can continue to operate even
when components fail by using redundant systems.
Question 08
What is a key feature of Infrastructure as a Service (IaaS)?
a) Complete management of data and applications by the provider
b) Users have control over virtual machines, storage, and networks
c) Reduced flexibility
d) Limited resource allocation
Correct Answer: b) Users have control over virtual machines, storage, and networks
Explanation: IaaS provides users with the ability to manage virtual machines, storage,
and networks, giving them more control over their cloud infrastructure.
Question 09
What does disaster recovery as a service (DRaaS) provide?
a) Backup and recovery solutions for critical business data
b) Increased network bandwidth
c) Reduced storage requirements
d) Improved CPU performance
Correct Answer: a) Backup and recovery solutions for critical business data
Explanation: DRaaS ensures business continuity by offering backup and recovery
services for data in the event of a disaster.
Question 10
What is a benefit of using containers in cloud computing?
a) Increased physical hardware needs
b) Faster and more efficient deployment of applications
c) Reduced network security
d) Increased storage costs
Correct Answer: b) Faster and more efficient deployment of applications
Explanation: Containers allow applications to be deployed quickly and efficiently,

a) To reduce CPU performance
b) To distribute network traffic across multiple servers
c) To increase storage capacity
d) To monitor encryption methods
Correct Answer: b) To distribute network traffic across multiple servers
Explanation: A load balancer helps distribute traffic evenly among servers, ensuring no
single server is overwhelmed.
Question 12
What is the function of an API gateway in cloud services?
a) To provide automated scaling
b) To manage and route API requests to appropriate services
c) To reduce storage capacity
d) To improve network bandwidth
Correct Answer: b) To manage and route API requests to appropriate services
Explanation: An API gateway handles incoming API requests, routing them to the correct
services and managing traffic flow efficiently.
Question 13

c) It reduces storage needs
d) It improves CPU performance
Correct Answer: b) It provides protection for sensitive information
Explanation: Encryption ensures that sensitive data in the cloud is protected from
unauthorized access, enhancing security.
Question 14
What is the benefit of cloud elasticity?
a) Static resource allocation
b) Ability to scale resources dynamically based on demand
c) Reduced encryption needs
d) Increased storage costs
Correct Answer: b) Ability to scale resources dynamically based on demand
