Fill in the blank: Cloud Computing is the delivery of computing services over the internet rather than through _______.
[local servers or personal devices]
28
True or False: Cloud computing allows end users to access information from anywhere, on any device.
True
29
What is a disadvantage of private cloud in terms of accessibility?
Private cloud is accessible within a particular area ## Footnote This means that the area of accessibility is restricted.
30
What is required for managing and operating private cloud services?
Skilled people are required ## Footnote Expertise is necessary since customer data and sensitive information do not flow out of private infrastructure.

35
What advantage does hybrid cloud provide in terms of cost efficiency?
Public clouds can handle variable or less-sensitive workloads ## Footnote This reduces the need to invest in additional private infrastructure.
36
What does scalability in a hybrid cloud allow for?
Burst workloads can use public cloud resources during high demand periods ## Footnote This is commonly referred to as cloud bursting.
37
True or False: Hybrid cloud enhances business continuity.
True ## Footnote It offers robust disaster recovery and backup options by spreading data and workloads across multiple environments.
38
What is a disadvantage of managing a hybrid cloud?
Businesses may lack the internal knowledge necessary ## Footnote Managing security can also be more challenging due to different access levels.
39
Fill in the blank: E-commerce companies can use public cloud resources during peak seasons while relying on private clouds for _______.
regular operations
40
What use case involves storing critical data in private clouds while using public clouds for backup?
