Answer: B) Multi-factor authentication (MFA)
Explanation: MFA enhances security by requiring additional verification beyond just passwords.
What is the primary function of a Cloud Access Security Broker (CASB)?
A) Manage cloud provider billing
B) Enforce security policies and visibility for cloud service usage
C) Automate cloud infrastructure
D) Provide hardware support
Answer: B) Enforce security policies and visibility for cloud service usage
Explanation: CASBs help organizations monitor and control cloud access and data security.
What is the advantage of “pay-as-you-go” cloud pricing?
A) Fixed monthly costs regardless of usage
B) Only pay for resources actually consumed, optimizing cost-efficiency
C) Requires upfront payment
D) No billing at all
Answer: B) Only pay for resources actually consumed, optimizing cost-efficiency
Explanation: Pay-as-you-go allows businesses to scale expenses with actual demand.
Which cloud storage service is best for storing unstructured data like images and videos?
A) Block storage
B) Object storage
C) File storage
