MS-900 Cloud Concepts & Microsoft 365 Overview — Questions and Answers
Question 1: What is a key benefit of cloud computing?
- Fixed hardware requirements
- Scalability and flexibility with lower upfront costs (Correct answer)
- Increased physical infrastructure
- Limited resource availability
Correct answer: Scalability and flexibility with lower upfront costs
A key benefit of cloud computing is its inherent scalability and flexibility, allowing users to easily adjust computing resources up or down as demand changes. This model also significantly lowers upfront costs by eliminating the need for large initial investments in hardware and infrastructure, as resources are consumed on a pay-as-you-go basis.
Question 2: Which cloud model delivers software over the internet?
- Infrastructure as a Service (IaaS)
- Platform as a Service (PaaS)
- Software as a Service (SaaS) (Correct answer)
- Network as a Service (NaaS)
Correct answer: Software as a Service (SaaS)
Software as a Service (SaaS) is a cloud computing model where a third-party provider hosts applications and makes them available to customers over the internet. Users access the software via a web browser or client application, without needing to manage the underlying infrastructure, operating systems, or platform components.
Question 3: What is the primary purpose of Microsoft 365?
- Hardware management
- Web hosting services
- Productivity, collaboration, and cloud services (Correct answer)
- Cryptocurrency trading
Correct answer: Productivity, collaboration, and cloud services
The primary purpose of Microsoft 365 is to provide a comprehensive suite of productivity, collaboration, and cloud services. It integrates familiar desktop applications like Word and Excel with cloud-based services such as OneDrive, Exchange Online, and Microsoft Teams, enabling seamless work, communication, and data storage across devices.
Question 4: Which feature helps protect Microsoft 365 users from phishing?
- Outlook Themes
- Microsoft Defender (Correct answer)
- Excel Templates
- PowerPoint Animations
Correct answer: Microsoft Defender
Microsoft Defender, particularly Microsoft Defender for Office 365, is a crucial feature that helps protect users from phishing attacks. It provides advanced threat protection capabilities, including safe attachments and safe links, which scan emails, links, and attachments for malicious content to prevent users from falling victim to phishing schemes.
Question 5: What is Azure Active Directory used for in Microsoft 365?
- Creating documents
- User identity and access management (Correct answer)
- Designing presentations
- Project scheduling
Correct answer: User identity and access management
Azure Active Directory (Azure AD) is Microsoft's cloud-based identity and access management service. In Microsoft 365, it is fundamental for managing user identities, authenticating users, and controlling their access to various services and resources. This ensures that only authorized individuals can access specific applications and data within the Microsoft 365 ecosystem.
Question 6: Which tool allows collaboration in real-time within Microsoft 365?
- Access
- Teams (Correct answer)
- Paint
- Notepad
Correct answer: Teams
Microsoft Teams is specifically designed as a hub for teamwork, enabling real-time collaboration through chat, video conferencing, and shared file editing. Its integrated features allow multiple users to work on documents simultaneously, communicate instantly, and conduct virtual meetings. This makes it the primary tool for dynamic, real-time interaction within Microsoft 365.
Question 7: Which of the following is a benefit of Microsoft 365 subscription model?
- One-time purchase
- Manual updates required
- Automatic updates and feature enhancements (Correct answer)
- Hardware upgrades
Correct answer: Automatic updates and feature enhancements
A key benefit of the Microsoft 365 subscription model is that it includes automatic updates and continuous feature enhancements. Subscribers always have access to the latest versions of applications and services without needing to purchase new software or manually install updates. This ensures users benefit from the newest security features, bug fixes, and productivity tools as soon as they are released.
Question 8: Which Microsoft 365 app is used for document creation?
- Power BI
- Word (Correct answer)
- Teams
- Yammer
Correct answer: Word
Microsoft Word is the industry-standard application within Microsoft 365 specifically designed for creating, editing, and formatting text-based documents. It offers a comprehensive suite of tools for writing reports, letters, resumes, and other professional or personal documents. While other apps have different primary functions, Word is dedicated to document creation.
Question 9: What does the term 'cloud elasticity' refer to?
- Fixed resource allocation
- Scaling resources based on current demand (Correct answer)
- Backup frequency
- Manual configuration changes
Correct answer: Scaling resources based on current demand
Cloud elasticity refers to the ability of cloud computing systems to dynamically scale resources up or down based on current demand. This means that computing power, storage, and network capacity can automatically expand during peak usage and contract during low usage. This flexibility ensures optimal performance and cost efficiency by only consuming resources when needed.
