Imagine you run a small bakery. You need ovens to bake bread. Which of these best explains the main advantage of using cloud computing for your bakery's computer needs?
Think about paying only for what you use instead of owning everything.
Cloud computing lets you rent computing resources like servers or storage as needed, similar to renting ovens only when baking. This saves money and effort compared to owning and maintaining your own equipment.
Look at the flowchart below showing how a file is saved to cloud storage. What is the correct order of steps?
Think about the natural order from user action to confirmation.
The user first uploads the file, which is sent over the internet to the cloud server. The server stores it and then sends confirmation back to the user.
Which cloud service model lets you rent virtual machines and storage but you manage the operating system and applications?
Think about who controls the OS and apps.
IaaS provides virtual hardware like servers and storage. You install and manage the OS and applications yourself. SaaS provides ready-to-use software, PaaS provides a platform to build apps, and FaaS runs code functions.
Which statement correctly compares public cloud and private cloud?
Think about who uses the resources.
Public cloud resources are shared by multiple users over the internet, while private cloud resources are dedicated to a single organization, often for security or compliance reasons.
A company uses cloud servers that cost $0.10 per hour each. They run 5 servers for 8 hours daily. If they double the servers to 10 for 8 hours daily, what is the monthly cost increase? (Assume 30 days in a month)
Calculate cost before and after doubling, then find the difference.
Original cost: 5 servers * 8 hours * $0.10 * 30 days = $120.
New cost: 10 servers * 8 hours * $0.10 * 30 days = $240.
Increase = $240 - $120 = $120.
