MS-900 Practice Test 5 — 10 Questions

Question 1

A company runs a critical application on-premises but wants to extend capacity to the cloud during peak demand without purchasing additional hardware. Which cloud deployment model best describes this strategy?

Accepted Answer

Hybrid cloud. A hybrid cloud model combines on-premises infrastructure (private cloud) with public cloud resources, enabling a company to 'burst' into the public cloud during peak demand without purchasing additional hardware. This strategy, often called cloud bursting, allows the critical application to run locally under normal conditions and seamlessly extend capacity to a public cloud provider like Azure during spikes.

Answer

Public cloud

Answer

Private cloud

Answer

Multi-cloud

Question 2

A company currently has Microsoft 365 E5 licenses for all users. They need to perform advanced threat hunting using queries across email, endpoints, and identities to investigate a potential security incident. Which of the following capabilities is already included in their existing license?

Accepted Answer

Microsoft 365 Defender (including advanced hunting). Microsoft 365 Defender (formerly Microsoft Threat Protection) includes advanced hunting capabilities that allow security teams to run Kusto Query Language (KQL) queries across email, endpoints, identities, and cloud apps. Since the company already has Microsoft 365 E5 licenses, this capability is included without any additional purchase.

Question 4

A company uses a cloud provider that charges them based solely on the exact number of gigabytes of storage used and the number of virtual machine hours consumed. They can increase or decrease usage at any time without any upfront commitment. Which essential characteristic of cloud computing does this billing model demonstrate?

Accepted Answer

Measured service. The billing model charges based on exact gigabytes of storage used and virtual machine hours consumed, which directly aligns with the 'measured service' characteristic of cloud computing. Measured service means cloud providers meter and bill customers precisely for the resources they consume, often using a pay-as-you-go model. This allows the company to pay only for what they use without upfront commitments, as described in the scenario.

Answer

Rapid elasticity

Answer

Resource pooling

Answer

On-demand self-service

Question 5

A company is preparing for a merger and wants to prevent communication between the Human Resources and Research departments regarding sensitive salary data during the due diligence period. They need a Microsoft Purview solution that can block all email and chat between users in these two groups, as well as prevent file sharing in Teams and SharePoint. Which solution should they configure?

Accepted Answer

Information Barriers. Information Barriers (IB) in Microsoft Purview are specifically designed to prevent communication and collaboration between defined user groups, such as HR and Research, by blocking email, Teams chat, and SharePoint/OneDrive file sharing. This solution enforces policies at the transport and service level, ensuring that sensitive salary data is not inadvertently shared during the merger due diligence period.

Question 6

A company with 40 users needs email, Teams, web Office apps, and cloud file storage but not desktop Office apps. Which option best matches the requirement?

Accepted Answer

Microsoft 365 Business Basic. Microsoft 365 Business Basic provides Exchange Online for email, Teams for collaboration, web versions of Office apps (Word, Excel, PowerPoint), and OneDrive for cloud file storage — all without including desktop Office apps. This plan is designed specifically for organizations that need cloud productivity tools but not locally installed Office applications, matching the 40-user requirement exactly.

Answer

Question 7

A company with 50 users currently has Microsoft 365 Business Basic licenses. They now want to give all users the desktop versions of Office apps and 1 TB of OneDrive storage per user. What is the most cost-effective licensing change?

Accepted Answer

Upgrade all users to Microsoft 365 Business Standard. Microsoft 365 Business Standard includes desktop Office apps, Exchange Online, Teams, and 1 TB OneDrive storage. Upgrading the existing subscriptions to Business Standard is more cost-effective than adding separate Microsoft 365 Apps for Business licenses because the latter does not include additional benefits like Exchange, and upgrading is typically priced per user as an incremental cost.

Answer

Purchase Microsoft 365 Apps for Business licenses for all users

Answer

Upgrade all users to Microsoft 365 Business Premium

Answer

Purchase Microsoft 365 E3 licenses for all users

Question 8

A company is evaluating moving its on-premises infrastructure to a cloud environment. They want a service that provides virtual machines, storage, and networking capabilities while retaining full control over the operating system and applications. Which cloud service model best meets this requirement?

Accepted Answer

Infrastructure as a Service (IaaS). Infrastructure as a Service (IaaS) provides virtualized computing resources, including virtual machines, storage, and networking, over the internet. The customer retains full administrative control over the operating system, applications, and middleware, while the cloud provider manages the underlying physical hardware. This matches the requirement for full OS and application control.

Answer

Software as a Service (SaaS)

Answer

Platform as a Service (PaaS)

Answer

Private Cloud

Question 9

A company uses a cloud storage service that automatically increases its storage capacity without any manual intervention as new files are added. This behavior is an example of which cloud computing characteristic?

Accepted Answer

Rapid elasticity. The scenario describes storage capacity automatically increasing as new files are added, which is the essence of rapid elasticity. This cloud characteristic allows resources to scale out and in automatically, often to the point where the user perceives unlimited capacity, without requiring manual provisioning or intervention.

Question 10

A company wants to provide its employees with access to email, calendar, and document editing tools through a web browser without installing any software. The provider manages all maintenance, updates, and security of the applications. Which cloud service model best describes this scenario?

This scenario describes Software as a Service (SaaS) because the provider delivers fully functional applications—such as email, calendar, and document editing—over the web, with no local installation required. The provider handles all maintenance, updates, and security, which is the defining characteristic of SaaS. Examples include Microsoft 365 (Exchange Online, Outlook, Word Online) and Google Workspace.
