ensuring that they are allocated appropriate physical resources.

Question 28

What is the purpose of a firewall in cloud security?

a) To optimize CPU performance
b) To encrypt all data
c) To monitor and control incoming and outgoing network traffic
d) To reduce storage requirements

Correct Answer: c) To monitor and control incoming and outgoing network traffic

Explanation: A firewall monitors and controls the flow of network traffic, acting as a
barrier between trusted and untrusted networks.

Question 29

What is the benefit of cloud resource pooling?

a) Resources are dedicated to individual users
b) Resources are shared across multiple users, optimizing utilization
c) Storage is reduced
d) Data is encrypted

Correct Answer: b) Resources are shared across multiple users, optimizing utilization

Explanation: Resource pooling allows cloud providers to serve multiple users efficiently
by sharing physical and virtual resources.

Question 30

What is a key advantage of using a hybrid cloud solution?

a) Complete control over data and infrastructure
b) Higher costs due to shared resources
c) Flexibility to use both public and private clouds
d) Increased latency

Correct Answer: c) Flexibility to use both public and private clouds

Explanation: Hybrid cloud solutions offer flexibility, allowing businesses to use both
public and private clouds depending on their needs.

Question 31

In cloud computing, what is the purpose of an SLA (Service Level Agreement)?

a) To encrypt data at rest
b) To define the guaranteed level of service between a provider and customer
c) To reduce storage space
d) To optimize CPU performance

Correct Answer: b) To define the guaranteed level of service between a provider and
customer

Explanation: An SLA outlines the performance, uptime, and service responsibilities that a
cloud provider guarantees to the customer.

Question 32

What is the primary purpose of using snapshots in cloud environments?

a) To monitor network traffic
b) To create backups of the current state of a virtual machine
c) To improve storage capacity
d) To encrypt sensitive information

Correct Answer: b) To create backups of the current state of a virtual machine

Explanation: Snapshots capture the current state of a virtual machine, allowing for quick
recovery or rollback in case of issues.

Question 33

Which of the following is a feature of cloud scalability?

a) Static resource allocation
b) Ability to increase or decrease resources based on demand
c) Increased storage costs
d) Reduced security measures

Correct Answer: b) Ability to increase or decrease resources based on demand

Explanation: Cloud scalability allows organizations to add or remove resources based on
current needs, ensuring efficient use of resources.

Question 34

What is the function of an intrusion detection system (IDS) in cloud environments?

a) To increase storage efficiency
b) To detect and alert administrators of potential security breaches
c) To monitor CPU performance
d) To encrypt sensitive data

Correct Answer: b) To detect and alert administrators of potential security breaches

Explanation: An IDS monitors network traffic for suspicious activity and alerts
administrators if any potential security breaches are detected.
