MTA Cloud Fundamentals 1 — Questions and Answers
Question 1: Which cloud service model provides virtualized computing resources like VMs, storage, and networking over the internet?
- SaaS
- PaaS
- IaaS (Correct answer)
- FaaS
Correct answer: IaaS
IaaS (Infrastructure as a Service) provides virtualized hardware resources including compute, storage, and networking, giving users control over the OS and applications.
Question 2: What is Microsoft Azure's primary cloud platform offering?
- A social networking service
- A public cloud platform providing compute, storage, and services globally (Correct answer)
- An enterprise resource planning system
- A content delivery network only
Correct answer: A public cloud platform providing compute, storage, and services globally
Microsoft Azure is a comprehensive public cloud platform offering over 200 products and services including VMs, databases, AI, and networking across global datacenters.
Question 3: Which cloud deployment model uses infrastructure exclusively maintained for a single organization?
- Public cloud
- Hybrid cloud
- Community cloud
- Private cloud (Correct answer)
Correct answer: Private cloud
A private cloud is cloud infrastructure operated exclusively for one organization, either on-premises or hosted by a third party, offering greater control and security.
Question 4: What does the term 'elasticity' mean in cloud computing?
- The ability to recover quickly from failures
- The ability to automatically scale resources up or down based on demand (Correct answer)
- The geographic distribution of data centers
- The speed of network connections
Correct answer: The ability to automatically scale resources up or down based on demand
Elasticity refers to the ability of a cloud system to automatically provision and release resources to match workload demand, scaling out during peaks and in during lulls.
Question 5: Which cloud service model handles the underlying infrastructure and runtime, letting developers focus on deploying code and data?
- IaaS
- SaaS
- PaaS (Correct answer)
- DaaS
Correct answer: PaaS
PaaS (Platform as a Service) abstracts the infrastructure layer, providing a managed runtime environment where developers deploy applications without managing servers.
Question 6: What is a major advantage of using the public cloud over traditional on-premises infrastructure?
- Greater physical control over hardware
- No need for internet connectivity
- Reduced capital expenditure by using a pay-as-you-go model (Correct answer)
- Guaranteed lower latency
Correct answer: Reduced capital expenditure by using a pay-as-you-go model
Public cloud shifts spending from CapEx (purchasing hardware) to OpEx (paying for usage), allowing organizations to scale without large upfront investments.
