MS-900 Microsoft 365 Fundamentals Cloud Computing Concepts 3 — Questions and Answers
Question 1: Which cloud deployment model is dedicated exclusively to a single organization and may be hosted on-premises or by a third party?
- Public cloud
- Hybrid cloud
- Private cloud (Correct answer)
- Community cloud
Correct answer: Private cloud
A private cloud is operated solely for one organization, providing greater control and security compared to a public cloud.
Question 2: What is the primary reason Microsoft 365 services can achieve higher availability than most on-premises solutions?
- They use older, more reliable hardware
- Microsoft distributes workloads across multiple global data centers (Correct answer)
- Users must manage their own redundancy
- Microsoft 365 runs on a single dedicated server per customer
Correct answer: Microsoft distributes workloads across multiple global data centers
Microsoft 365 leverages a globally distributed network of data centers with redundancy, enabling high availability that most on-premises setups cannot match.
Question 3: In cloud computing, what does 'agility' refer to?
- The speed at which data is backed up
- The ability to rapidly provision and deprovision IT resources (Correct answer)
- The number of virtual machines a provider supports
- The encryption strength of data at rest
Correct answer: The ability to rapidly provision and deprovision IT resources
Cloud agility means organizations can quickly spin up or remove IT resources to respond to changing business needs.
Question 4: Which of the following describes a 'consumption-based' pricing model in cloud computing?
- Paying a fixed monthly fee regardless of usage
- Paying only for the resources you actually use (Correct answer)
- Purchasing hardware upfront for a fixed period
- Signing a multi-year contract for reserved capacity
Correct answer: Paying only for the resources you actually use
Consumption-based pricing means customers are billed only for the compute, storage, or services they actually consume.
Question 5: Which Microsoft 365 component is classified as a cloud-based identity service?
- Microsoft Exchange Server (on-premises)
- Azure Active Directory (Microsoft Entra ID) (Correct answer)
- Windows Server Active Directory
- Microsoft SQL Server
Correct answer: Azure Active Directory (Microsoft Entra ID)
Azure Active Directory (now Microsoft Entra ID) is Microsoft's cloud-based identity and access management service used by Microsoft 365.
Question 6: What is a key advantage of geo-distribution in Microsoft 365?
- It reduces the number of features available to users
- It ensures data and services are available closer to users worldwide, reducing latency (Correct answer)
- It limits data storage to a single country
- It requires on-premises hardware in every office
Correct answer: It ensures data and services are available closer to users worldwide, reducing latency
Geo-distribution places Microsoft 365 resources in data centers around the world, lowering latency and improving performance for global users.
Question 7: A company's cloud application automatically provisions additional servers when CPU usage exceeds 80% and removes them when usage drops below 30%. This is an example of:
- Fault tolerance
- Manual scaling
- Auto-scaling (elasticity) (Correct answer)
- Geo-replication
Correct answer: Auto-scaling (elasticity)
Auto-scaling, a form of elasticity, automatically adjusts resource capacity in response to real-time demand metrics.
