MS-900 Describe cloud concepts Practice Test 8 — 15 Questions

Question 1

WideWorldImporters (WWI) is a retail company with 2,000 employees using Microsoft 365 Business Premium. They have a mix of Windows 10 and Windows 11 devices managed by Microsoft Intune. WWI wants to deploy a new line-of-business (LOB) app to all devices. The app is a Win32 app packaged as an .intunewin file. The IT administrator needs to ensure the app is installed automatically on all devices within 24 hours. Which deployment method should the administrator use?

Choose an answer to begin — your selection is scored in the full session.

Accepted Answer

Add the app as a required deployment for all devices. Intune’s required deployment assignment for Win32 apps automatically installs the app on all targeted devices without user intervention. Intune checks in within its default refresh cycle (approximately 8 hours), ensuring installation within 24 hours. Option A is incorrect because available deployment requires users to initiate installation from the Company Portal, which does not guarantee automatic installation. Option B (in your options list, option B is actually 'Add the app as an available deployment...') is incorrect for the same reason – an available deployment relies on user action. Option D is incorrect because Microsoft Store for Business is designed for store-based apps, not for custom line-of-business Win32 apps packaged as .intunewin files. Azure AD Application Proxy (listed as option A) is for publishing on-premises web apps externally, not for device app deployment.

Answer

Use Azure AD Application Proxy to publish the app

Answer

Add the app as an available deployment for all users

Answer

Publish the app to Microsoft Store for Business and sync with Intune

Question 2

Adatum Corporation is a small business with 50 employees. They use Microsoft 365 Business Basic and SharePoint Online for document management. Employees frequently share files with external partners via email attachments. The CEO wants to reduce the risk of data leaks and ensure that shared files are protected even after they are sent. Which Microsoft 365 solution should Adatum implement?

Accepted Answer

Microsoft Purview Message Encryption. Microsoft Purview Message Encryption allows users to encrypt emails and attachments, and can enforce restrictions such as preventing forwarding or printing, thus protecting data even after it is sent. Option A is wrong because SharePoint external sharing settings control access to SharePoint content, not email attachments. Option B is wrong because Data Loss Prevention (DLP) policies can detect and prevent sharing of sensitive information, but they do not automatically protect attachments after they have been sent. Option C is wrong because sensitivity labels can classify and protect data, but they require manual application and may not automatically encrypt attachments in transit.

Answer

SharePoint external sharing settings

Answer

Data Loss Prevention (DLP) policies

Answer

Sensitivity labels

Question 3

A company's CFO is pleased that they only pay for the compute and storage resources consumed each month, with no upfront hardware costs. This billing model is a direct result of which cloud computing characteristic?

Accepted Answer

Measured service. The CFO's observation that the company only pays for consumed compute and storage resources with no upfront hardware costs directly reflects the 'measured service' characteristic of cloud computing. Measured service means cloud providers meter resource usage (e.g., CPU hours, GB-months of storage) and bill based on actual consumption, typically using a pay-as-you-go model. This eliminates the need for capital expenditure on hardware, as costs are operational and tied to usage metrics.

Answer

On-demand self-service

Answer

Broad network access

Answer

Resource pooling

Question 4

A startup wants to focus only on developing and deploying its application code without managing underlying servers or operating systems. Which cloud service model best fits this need?

Accepted Answer

Platform as a Service (PaaS). Platform as a Service (PaaS) is the correct choice because it abstracts the underlying infrastructure, including servers, operating systems, and runtime environments, allowing the startup to focus solely on developing and deploying application code. With PaaS, the cloud provider manages the OS patching, hardware scaling, and middleware, while the customer only manages the application and data. This directly matches the requirement of not managing servers or operating systems.

Answer

Infrastructure as a Service (IaaS)

Answer

Software as a Service (SaaS)

Answer

On-premises deployment

Question 5

A cloud provider offers virtual machines, but customers must install, configure, and maintain the operating system and applications. Which cloud service model does this describe?

Accepted Answer

IaaS (Infrastructure as a Service). This scenario describes Infrastructure as a Service (IaaS), where the cloud provider supplies virtualized computing resources such as virtual machines, storage, and networking, but the customer retains full control over the operating system, middleware, and applications. In IaaS, the provider manages only the physical infrastructure (hypervisor, servers, storage, and network), while the customer is responsible for OS installation, configuration, patching, and application management. This aligns directly with the question's description of customer-managed OS and applications on provider-hosted VMs.
