- A
On-demand self-service
Why wrong: On-demand self-service enables users to provision computing capabilities automatically without requiring human interaction with the service provider. This does not specifically address the ability to access resources from various device types.
- B
Broad network access
Broad network access means that resources are available over the network and can be accessed by standard mechanisms that promote use by heterogeneous client platforms (e.g., mobile phones, tablets, laptops, and workstations). This directly matches the requirement to access cloud resources from a variety of devices.
- C
Resource pooling
Why wrong: Resource pooling refers to the provider's computing resources being pooled to serve multiple customers using a multi-tenant model, with physical and virtual resources dynamically assigned according to consumer demand. It does not relate to device accessibility.
- D
Measured service
Why wrong: Measured service means that cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service. It is about monitoring and billing, not about multi-device access.
Quick Answer
The answer is broad network access. This characteristic of cloud computing is correct because it explicitly describes the ability to access cloud services and manage resources from anywhere using standard network protocols like HTTPS or SSH, across a wide range of heterogeneous client platforms such as laptops, smartphones, and tablets—without requiring any location-specific infrastructure. On the AWS Certified Cloud Practitioner CLF-C02 exam, this concept tests your understanding of the five essential cloud characteristics defined by NIST; a common trap is confusing broad network access with resource pooling or rapid elasticity, but the key differentiator here is the emphasis on universal device and location independence. To remember it, think of the phrase “any device, anywhere, anytime”—if the scenario mentions diverse devices and remote access, broad network access is the characteristic being described.

Correct answer & explanation
Broad network access
The requirement for employees to access cloud applications and manage resources from anywhere using laptops, smartphones, and tablets directly represents broad network access. This essential characteristic means that cloud services are available over standard network protocols (e.g., HTTP/HTTPS, SSH) and can be accessed by heterogeneous client platforms, including mobile devices, workstations, and tablets, without requiring location-specific infrastructure.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'broad network access' with 'on-demand self-service' because both involve user interaction, but the question's emphasis on 'from anywhere using a variety of devices' is a direct match for the NIST definition of broad network access, not the automated provisioning aspect of self-service.
Detailed technical explanation
How to think about this question
Broad network access is defined in 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 (e.g., mobile phones, tablets, laptops, and workstations).' Under the hood, this relies on ubiquitous protocols like TLS 1.2/1.3 for secure transport, RESTful APIs over HTTP/2, and WebSocket for real-time communication, ensuring consistent access regardless of the client's operating system or form factor. A subtle behavior is that while broad network access enables global reach, it also introduces latency variability and dependency on internet connectivity, which is why AWS services like Direct Connect exist for dedicated private access.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A company's IT admin needs to give a contractor read-only access to production logs without sharing account credentials. Using role-based access control (RBAC) and temporary scoped permissions — not a permanent shared password — is the correct pattern. Questions like this test whether you can apply least-privilege access across cloud identity services.

Variation 1. A company's employees access AWS services using the AWS Management Console from their office laptops, the AWS mobile app on their smartphones, and the AWS CLI from their home computers. Which cloud computing characteristic does this illustrate?
easy- A.Rapid elasticity
- B.Resource pooling
- ✓ C.Broad network access
- D.Measured service
Why C: Broad network access is the correct answer because the scenario describes employees accessing AWS services from multiple types of devices (office laptops, smartphones, home computers) using different access methods (AWS Management Console, AWS mobile app, AWS CLI). This directly illustrates the cloud characteristic that resources are available over the network and can be accessed by standard protocols (e.g., HTTPS for the console and mobile app, HTTP/HTTPS for CLI API calls) from a wide range of client platforms, including mobile phones, laptops, and workstations.
