MS-900 Describe cloud concepts Practice Question
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?
⚠ Common exam trap
Many exam-takers confuse 'broad network access' with 'resource pooling' because both involve multi-device scenarios, but resource pooling is about the provider's internal multi-tenant architecture, not the customer's ability to connect from any device.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
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 analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rapid elasticity
Why it's wrong here
Rapid elasticity enables resources to be provisioned and released automatically, scaling out or in based on real-time demand. This characteristic helps handle workload spikes and performance fluctuations, but it does not address how users connect from different geographic locations or devices. The scenario described is about universal device access, which is purely a network capability.
- ✗
Measured service
Why it's wrong here
Measured service allows cloud providers to meter resource usage, such as processing power, storage, and bandwidth, and bill customers accordingly. This metering capability enables cost transparency and usage optimization, but it has no bearing on whether users can reach cloud services from various devices. Accessibility from anywhere is a function of network reachability, not consumption-based billing.
- ✓
Broad network access
Why this is correct
Broad network access is the cloud characteristic that makes resources available over the network through standard protocols, allowing access from laptops, mobile phones, and other devices with internet connectivity. This ensures that employees can securely connect to corporate applications and data from any location, fulfilling the need described in the question. It is one of the essential NIST-defined characteristics of cloud computing, distinct from scaling or metering.
- ✗
Resource pooling
Why it's wrong here
Resource pooling involves the provider serving multiple customers from shared physical and virtual resources using a multi-tenant model. This pooling provides economies of scale and allows dynamic assignment of resources, but it does not define the mechanism by which users access those resources. Accessing a company's cloud services from various devices is unrelated to how infrastructure is shared; it is governed by broad network access.

Same concept, more angles
4 more ways this is tested on MS-900
These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. 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?
medium- A.Sensitivity labels
- B.Microsoft Planner
- C.Data Loss Prevention (DLP)
- ✓ D.Broad network access
Why D: 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.
Variation 2. A business needs staff to access Microsoft 365 services from different locations using only an internet connection. Which cloud benefit is being used?
easy- A.Capital expenditure spending
- B.Manual provisioning
- ✓ C.Broad network access
- D.Server virtualization only
Why C: Broad network access is a core characteristic of cloud computing defined by NIST SP 800-145. It means that resources are available over the network and can be accessed by standard client platforms (e.g., laptops, tablets, smartphones) using only an internet connection, without requiring a dedicated private link or on-premises hardware. In this scenario, staff accessing Microsoft 365 from different locations via the internet directly demonstrates broad network access.
Variation 3. A marketing manager can access the company's cloud resources from her laptop at home, her tablet while traveling, and her smartphone. Which essential characteristic of cloud computing does this describe?
easy- A.Resource pooling
- B.Scalability
- ✓ C.Broad network access
- D.Measured service
Why C: Broad network access means cloud resources can be accessed over standard network protocols (e.g., HTTPS, TLS) from a wide range of client devices, such as laptops, tablets, and smartphones. The scenario explicitly describes access from multiple device types and locations, which is the defining characteristic of broad network access as per NIST SP 800-145.
Variation 4. A cloud user can access their files from a work desktop, a personal laptop at home, and a mobile phone while traveling. Which essential characteristic of cloud computing does this scenario best illustrate?
easy- A.On-demand self-service
- ✓ B.Broad network access
- C.Resource pooling
- D.Rapid elasticity
Why B: Broad network access is the correct answer because it describes the ability to access cloud resources from diverse client platforms (work desktop, personal laptop, mobile phone) over the network using standard protocols such as HTTPS, SSH, or VPN. This characteristic ensures that services are available from any location with internet connectivity, not just from a single device or network.
