MS-900 Microsoft 365 Fundamentals Cloud Computing Concepts 5 — Questions and Answers
Question 1: According to NIST, which cloud characteristic allows a provider to serve multiple customers using shared physical resources while keeping each customer's data isolated?
- On-demand self-service
- Broad network access
- Resource pooling (Correct answer)
- Measured service
Correct answer: Resource pooling
Resource pooling means the provider uses a multi-tenant model to serve multiple customers from shared infrastructure, with logical isolation between them.
Question 2: What does 'broad network access' mean in the NIST definition of cloud computing?
- Cloud services must only be accessed from corporate offices
- Cloud capabilities are available over the network and accessed through standard mechanisms across diverse devices (Correct answer)
- The cloud provider owns the last-mile internet connection to users
- Data must be transferred over a dedicated private line
Correct answer: Cloud capabilities are available over the network and accessed through standard mechanisms across diverse devices
Broad network access means cloud services are accessible over standard networks (internet) from any device such as phones, tablets, or laptops.
Question 3: A company is evaluating Microsoft 365 and wants to understand the financial benefit of predictable monthly costs. Which OpEx advantage does this represent?
- Reduced need for IT staff
- Predictable, subscription-based spending that simplifies budgeting (Correct answer)
- One-time payment for perpetual software licenses
- Free hardware replacement every three years
Correct answer: Predictable, subscription-based spending that simplifies budgeting
Microsoft 365's subscription model provides predictable monthly costs, making it easier for finance teams to budget compared to unpredictable CapEx spending.
Question 4: Which of the following is a responsibility that CUSTOMERS always retain regardless of the cloud service model (IaaS, PaaS, or SaaS)?
- Managing physical servers
- Patching the operating system
- Managing user accounts and data (Correct answer)
- Configuring network switches
Correct answer: Managing user accounts and data
Regardless of the service model, customers are always responsible for managing their own data and user identity/access.
Question 5: What is the primary purpose of Microsoft's trust center and compliance offerings within Microsoft 365?
- To sell additional hardware warranties
- To demonstrate that Microsoft 365 meets global regulatory and security standards (Correct answer)
- To provide free legal advice to customers
- To replace the need for internal IT security teams
Correct answer: To demonstrate that Microsoft 365 meets global regulatory and security standards
Microsoft's trust center communicates the compliance certifications and security practices that help organizations meet regulatory requirements when using Microsoft 365.
Question 6: Which scenario best illustrates the 'measured service' characteristic of cloud computing?
- A company receives a fixed bill regardless of how many emails it sends
- A company is charged based on the exact number of gigabytes of storage and compute hours used each month (Correct answer)
- A company must estimate usage annually and pay upfront
- A company pays a flat fee per user with no usage tracking
Correct answer: A company is charged based on the exact number of gigabytes of storage and compute hours used each month
Measured service means cloud usage is monitored, controlled, and reported, and customers pay based on actual consumption metrics.
Question 7: When Microsoft 365 automatically fails over to a secondary data center during an outage, this demonstrates which cloud benefit?
- Elasticity
- Disaster recovery / business continuity (Correct answer)
- On-demand self-service
- Consumption-based billing
Correct answer: Disaster recovery / business continuity
Automatic failover to a secondary site is a disaster recovery and business continuity capability that keeps services running during an outage.
