MS-900 Describe cloud concepts Practice Test 7 — 15 Questions

Question 1

A tenant administrator is advising a department that wants to use Microsoft 365 and another public cloud provider for different workloads. Cloud concept or benefit best matches this requirement?

Accepted Answer

Multi-cloud. C is correct because multi-cloud refers to using multiple public cloud providers (e.g., Microsoft 365 and another provider like AWS or Google Cloud) for different workloads, which directly matches the requirement. This allows the organization to avoid vendor lock-in, optimize costs, and leverage best-of-breed services across clouds.

Question 2

A business stakeholder asks how Microsoft 365 can help them access cloud resources from laptops, tablets, and phones over the internet. Cloud concept or benefit best matches this requirement?

Accepted Answer

Broad network access. Broad network access is a core NIST cloud computing characteristic that enables resources to be accessed over the network by standard mechanisms (e.g., mobile phones, tablets, laptops, and workstations). This directly matches the stakeholder's requirement for accessing cloud resources from various devices over the internet, as Microsoft 365 leverages HTTPS and standard protocols to provide ubiquitous access.

Question 3

While preparing a Microsoft 365 adoption plan, a consultant is asked to reduce maintenance of power, cooling, and server replacement. Cloud concept or benefit best matches this requirement?

Accepted Answer

Reduced data center management. Reduced data center management is the correct answer because the requirement to reduce maintenance of power, cooling, and server replacement directly maps to the cloud benefit of offloading physical infrastructure responsibilities to the cloud provider. In Microsoft 365, this is realized through the shared responsibility model where Microsoft manages the underlying hardware, facilities, and environmental controls, allowing the organization to focus on application and data management rather than data center operations.

Question 4

A service owner is comparing Microsoft 365 capabilities and needs to understand which security tasks Microsoft handles and which remain with the customer. Cloud concept or benefit best matches this requirement?

Accepted Answer

Shared responsibility model. The shared responsibility model defines which security tasks are handled by Microsoft (e.g., physical security, hypervisor patching) and which remain with the customer (e.g., user access management, data classification). This directly matches the service owner's need to understand the division of security responsibilities in Microsoft 365.

Question 5

During requirements gathering, an IT manager says the organization must keep services available during a hardware failure. Cloud concept or benefit best matches this requirement?

Accepted Answer

High availability. High availability (C) is the correct cloud concept because it directly addresses the requirement to keep services operational during hardware failure. In Microsoft 365, high availability is achieved through redundant infrastructure, such as multiple server instances across different Azure availability zones, and automatic failover mechanisms that ensure service continuity without manual intervention.

Question 6

A company needs a dedicated, private network connection between its on-premises data center and Microsoft's cloud infrastructure to support a hybrid deployment with low latency and high reliability. The connection must not traverse the public internet. Which service should they use?

Accepted Answer

Azure ExpressRoute. Azure ExpressRoute is the correct choice because it provides a dedicated, private network connection from an on-premises data center directly into Microsoft's cloud infrastructure, bypassing the public internet entirely. This ensures low latency, high reliability, and consistent performance for hybrid deployments, as the traffic traverses a private MPLS or Ethernet link rather than the unpredictable internet.

Question 7

A colleague says, 'The public cloud is cheaper because you only pay for the resources you use, like compute hours or storage space.' Which cloud computing characteristic directly supports this pay-as-you-go model?

Accepted Answer

Measured service. Measured service is the cloud computing characteristic that enables a pay-as-you-go model by metering resource usage (e.g., compute hours, storage GB-months, outbound data transfer) and providing transparent billing based on actual consumption. This allows providers like Azure to charge only for what is used, directly supporting the colleague's statement that the public cloud is cheaper because you pay only for resources consumed.

Answer

Rapid elasticity

Answer

Broad network access

Answer

On-demand self-service

Question 8

Which cloud computing characteristic allows a company to access resources like storage and databases from any device with an internet connection without needing to manage the physical infrastructure?

Accepted Answer

Broad network access. Broad network access is the correct answer because it describes the ability to access cloud resources (such as storage and databases) over the network via standard protocols (e.g., HTTP/HTTPS, SMB, NFS) from any device (laptop, smartphone, tablet) with an internet connection, without requiring the customer to manage the underlying physical infrastructure. This characteristic is defined by NIST SP 800-145 as 'capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms.'

Answer

Rapid elasticity

Answer

Measured service

Answer

Resource pooling

Question 9

A cloud provider uses a multi-tenant model where physical and virtual resources are dynamically assigned and reassigned according to consumer demand. This is an example of which cloud computing characteristic?

Accepted Answer

Resource pooling. Resource pooling is the correct answer because the multi-tenant model described involves the cloud provider pooling physical and virtual resources (e.g., compute, storage, network) to serve multiple consumers, with resources dynamically assigned and reassigned based on demand. This is a core characteristic of cloud computing as defined by NIST SP 800-145, where the provider's resources are pooled to achieve economies of scale while maintaining logical isolation between tenants.

Answer

Rapid elasticity

Answer

On-demand self-service

Answer

Measured service

Question 10

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.

Answer

On-demand self-service

Answer

Broad network access

Answer

Resource pooling

Question 11

A company deploys a custom application on a cloud platform where they manage the operating system and runtime environment, but the cloud provider manages the underlying physical infrastructure, storage, and networking. Which cloud service model is being used?

Accepted Answer

Infrastructure as a Service (IaaS). The scenario describes a model where the customer manages the operating system and runtime environment, while the cloud provider handles the physical infrastructure, storage, and networking. This aligns precisely with Infrastructure as a Service (IaaS), as IaaS provides virtualized computing resources (e.g., virtual machines) where the customer retains control over the OS, middleware, and applications, but the provider manages the underlying hardware, hypervisor, and physical network.

Answer

Platform as a Service (PaaS)

Answer

Software as a Service (SaaS)

Answer

Function as a Service (FaaS)

Question 12

A development team uses a cloud service to run applications where the provider manages the runtime environment, operating system, and middleware. The team only writes and uploads code. Which service model are they using?

Accepted Answer

PaaS (Platform as a Service). The scenario describes the team writing and uploading code while the provider manages the runtime environment, operating system, and middleware. This is the defining characteristic of Platform as a Service (PaaS), where the cloud provider abstracts the underlying infrastructure and platform layers, allowing developers to focus solely on application code. In PaaS, the provider handles OS patching, runtime updates, and middleware configuration, which matches the description exactly.

Answer

IaaS (Infrastructure as a Service)

Answer

SaaS (Software as a Service)

Answer

FaaS (Function as a Service)

Question 13

A company uses a cloud service where they pay only for the compute hours their virtual machines run. They can increase or decrease the number of VMs instantly based on demand. Which two cloud computing characteristics are demonstrated? (Choose two.)

Accepted Answer

Rapid elasticity. B is correct because rapid elasticity allows the company to instantly increase or decrease the number of virtual machines based on demand, scaling resources up or down automatically. C is correct because measured service ensures that the company pays only for the compute hours their VMs run, with usage metered and billed accordingly.

Answer

On-demand self-service

Answer

Resource pooling

Question 14

A company is deploying a cloud solution where they have the ability to quickly scale up resources during peak demand and scale down during off-peak hours, paying only for what they use. They also need the provider to automatically manage the underlying platform, including patching the operating system. Which combination of cloud characteristics and service model best describes this scenario?

Accepted Answer

Elasticity and PaaS. The scenario describes elasticity (the ability to scale resources up and down automatically based on demand) and Platform as a Service (PaaS), where the provider manages the underlying platform, including OS patching. Elasticity is a key cloud characteristic that enables dynamic scaling, and PaaS abstracts infrastructure management, aligning perfectly with the requirement for automatic platform maintenance.

Rapid elasticity and SaaS

Answer

Measured service and PaaS

Question 15

A business wants to use a cloud solution where they can scale computing resources up or down automatically based on demand and only pay for what they use. The cloud provider manages the underlying hardware. Which two cloud characteristics are being described? (Choose two.)

Accepted Answer

Elasticity. Elasticity is correct because it describes the ability to automatically scale computing resources up or down based on demand, which is a key characteristic of cloud computing. The scenario explicitly states that resources scale automatically, which aligns with elasticity rather than just the ability to scale (scalability). Measured service is correct because the business pays only for what they use, which is the pay-per-use billing model enabled by metering resource consumption.

Answer

Scalability

Answer

High availability
