- A
Resource pooling
Why wrong: Incorrect. Resource pooling refers to the provider's computing resources being pooled to serve multiple consumers, with physical and virtual resources dynamically assigned and reassigned. The scenario focuses on how users access the application from various devices, not on multi-tenant resource sharing.
- B
Measured service
Why wrong: Incorrect. Measured service means cloud systems automatically control and optimize resource use by leveraging a metering capability at some level of abstraction appropriate to the type of service. The scenario does not mention usage monitoring or billing granularity.
- C
Broad network access
Correct. Broad network access means capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous client platforms (e.g., mobile phones, tablets, laptops, and workstations). The scenario explicitly describes access from multiple device types over the internet.
- D
Rapid elasticity
Why wrong: Incorrect. Rapid elasticity refers to the ability to scale resources up and down quickly, often automatically. The scenario does not describe scaling behavior; it describes access patterns from different devices.
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 multinational company hosts its customer relationship management (CRM) application on AWS. Sales team members access the CRM from various locations using desktop computers, laptops, tablets, and smartphones. They connect over the internet through standard web browsers. Which essential characteristic of cloud computing does this scenario best illustrate?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue:
"best"Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
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
This scenario best illustrates broad network access because the CRM application is accessed over the internet by sales team members using a variety of devices (desktops, laptops, tablets, smartphones) through standard web browsers. Broad network access is the cloud computing characteristic that defines the ability to access resources via standard protocols (e.g., HTTPS, TLS) from heterogeneous client platforms, which is exactly what is described here.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Incorrect. Rapid elasticity refers to the ability to scale resources up and down quickly, often automatically. The scenario does not describe scaling behavior; it describes access patterns from different devices.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse broad network access with resource pooling because both involve 'many users,' but broad network access is about device and protocol diversity, not shared infrastructure.
Trap categories for this question
Scenario analysis trap
Incorrect. Resource pooling refers to the provider's computing resources being pooled to serve multiple consumers, with physical and virtual resources dynamically assigned and reassigned. The scenario focuses on how users access the application from various devices, not on multi-tenant resource sharing.
Detailed technical explanation
How to think about this question
Broad network access is defined by the NIST SP 800-145 standard 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).' In practice, this relies on protocols like HTTPS (RFC 2818) and WebSocket (RFC 6455) to ensure consistent access across devices. A real-world scenario where this matters is a global sales team using a CRM via a mobile app on 4G and a desktop browser on corporate Wi-Fi, both leveraging the same RESTful API endpoints.
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.
