- A
On-demand self-service
Why wrong: On-demand self-service refers to a consumer's ability to provision computing capabilities automatically without requiring human interaction with each service provider. The scenario does not describe provisioning or automation; it describes access to an existing application from various devices.
- B
Resource pooling
Why wrong: Resource pooling means that the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with physical and virtual resources dynamically assigned. The scenario focuses on device access, not multi-tenancy or resource sharing.
- C
Broad network access
This is correct. Broad network access is the ability to access cloud services over the network using standard protocols (e.g., HTTP/HTTPS) from a variety of client devices such as laptops, tablets, and smartphones. The sales team accessing the CRM from different devices via the internet is a textbook example.
- D
Measured service
Why wrong: Measured service means that cloud systems automatically control and optimize resource use by leveraging a metering capability. While the CRM provider likely tracks usage, the scenario emphasizes access from diverse devices, not metering or billing.
CLF-C02 Cloud Concepts Practice Question
This CLF-C02 practice question tests your understanding of cloud concepts. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company's sales team uses a cloud-based CRM application. Sales representatives access the CRM from their laptops in the office, from tablets at customer sites, and from their smartphones while traveling, all over the internet. The application works consistently across all devices without requiring any custom client software on each device. Which essential characteristic of cloud computing does this scenario BEST demonstrate?

Correct answer & explanation
Broad network access
The scenario describes sales representatives accessing the CRM application from laptops, tablets, and smartphones over the internet without needing custom client software. This directly illustrates broad network access, which is the cloud computing characteristic that resources are available over the network and can be accessed by standard mechanisms (e.g., HTTPS, REST APIs) from a wide range of heterogeneous client platforms (e.g., mobile phones, tablets, laptops). The consistent experience across devices without custom software is the hallmark of broad network access.
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 often confuse broad network access with on-demand self-service because both involve user interaction, but broad network access specifically focuses on the variety of client platforms and network-based accessibility, not the ability to self-provision resources.

Detailed technical explanation
How to think about this question
Broad network access is defined in NIST SP 800-145 and relies on standard network protocols such as HTTP/HTTPS (RFC 7230), WebSockets (RFC 6455), or RESTful APIs to ensure interoperability across diverse client platforms. Under the hood, this characteristic often requires the cloud service to expose endpoints that are reachable over public or private networks using TLS 1.2/1.3, and the client devices must support these standard protocols without proprietary plugins. In real-world scenarios, a CRM accessed via a mobile browser on 4G LTE and a desktop browser on a corporate LAN both use the same HTTPS requests, demonstrating broad network access in action.
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.
