- A
Measured service
Why wrong: Measured service refers to the capability of cloud systems to automatically control and optimize resource usage by metering usage (e.g., storage, processing, bandwidth). This enables pay-as-you-go billing. The scenario does not describe metering or billing, so this is incorrect.
- B
Resource pooling
Why wrong: Resource pooling is the ability to serve multiple customers from the same physical infrastructure, with resources dynamically assigned and reassigned according to demand. The scenario focuses on access from various devices and locations, not on multi-tenancy or infrastructure sharing, so this is incorrect.
- C
Broad network access
Broad network access is a core cloud characteristic that allows resources to be accessed over the network using standard protocols (such as HTTP/HTTPS) from a wide range of client devices (laptops, tablets, smartphones). This aligns directly with the requirement for employees to access applications via standard web browsers from various devices without dedicated hardware or software.
- D
Rapid elasticity
Why wrong: Rapid elasticity is the ability to quickly scale resources up or down, often automatically, to match demand. The scenario does not mention scaling or changing capacity; it focuses on access methods and device diversity, so this is incorrect.
CLF-C02 Cloud Concepts Practice Question
This CLF-C02 practice question tests your understanding of cloud concepts. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 global company has employees who work from various locations and use different devices such as laptops, tablets, and smartphones to access corporate applications. The company plans to migrate its applications to AWS and wants all employees to access these applications directly from the internet using standard web browsers without requiring any dedicated hardware or software at each branch. Which essential characteristic of cloud computing does this scenario BEST demonstrate?
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
The scenario describes employees accessing corporate applications from various devices and locations using only standard web browsers, without dedicated hardware or software. This directly aligns with the cloud computing characteristic of broad network access, which mandates that resources are accessible over the network by standard mechanisms (e.g., HTTPS, TLS 1.2/1.3) from heterogeneous client platforms (laptops, tablets, smartphones). The key is that no site-to-site VPN appliances or thick client software are required—just a browser and an internet connection.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

- ✗
Measured service
Why it's wrong here
Measured service refers to the capability of cloud systems to automatically control and optimize resource usage by metering usage (e.g., storage, processing, bandwidth). This enables pay-as-you-go billing. The scenario does not describe metering or billing, so this is incorrect.
When this WOULD be correct
A question asks: 'A company wants to track and optimize its cloud spending by monitoring resource usage per department. Which cloud characteristic enables this?' Then 'Measured service' is correct because it provides usage metering and billing transparency.
- ✗
Resource pooling
Why it's wrong here
Resource pooling is the ability to serve multiple customers from the same physical infrastructure, with resources dynamically assigned and reassigned according to demand. The scenario focuses on access from various devices and locations, not on multi-tenancy or infrastructure sharing, so this is incorrect.
When this WOULD be correct
A company wants to ensure that its cloud provider can dynamically assign compute resources to different departments based on demand, without the departments needing to know the exact physical location of the resources. This would best demonstrate resource pooling.
- ✓
Broad network access
Why this is correct
Broad network access is a core cloud characteristic that allows resources to be accessed over the network using standard protocols (such as HTTP/HTTPS) from a wide range of client devices (laptops, tablets, smartphones). This aligns directly with the requirement for employees to access applications via standard web browsers from various devices without dedicated hardware or software.

Rapid elasticity
Why it's wrong here
Rapid elasticity is the ability to quickly scale resources up or down, often automatically, to match demand. The scenario does not mention scaling or changing capacity; it focuses on access methods and device diversity, so this is incorrect.
When this WOULD be correct
A company experiences unpredictable spikes in traffic to its e-commerce website during flash sales. The cloud automatically provisions additional servers to handle the load and deprovisions them when traffic subsides. This scenario would best demonstrate rapid elasticity.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CLF-C02 exam frequently reuses these exact scenarios with slightly different constraints.
✓Broad network accessCorrect answer▾
Why this is correct
Broad network access is a core cloud characteristic that allows resources to be accessed over the network using standard protocols (such as HTTP/HTTPS) from a wide range of client devices (laptops, tablets, smartphones). This aligns directly with the requirement for employees to access applications via standard web browsers from various devices without dedicated hardware or software.
✗Measured serviceWrong answer — click to see why▾
Why this is wrong here
The scenario emphasizes accessing applications from any device via standard web browsers without dedicated hardware, which is 'broad network access.' 'Measured service' refers to metering and billing based on usage, not ubiquitous access.
★ When this WOULD be the correct answer
A question asks: 'A company wants to track and optimize its cloud spending by monitoring resource usage per department. Which cloud characteristic enables this?' Then 'Measured service' is correct because it provides usage metering and billing transparency.
Why candidates choose this
Candidates may confuse 'measured service' with any measurable benefit of cloud, such as pay-as-you-go, but the question focuses on access from diverse devices, not cost tracking.
✗Resource poolingWrong answer — click to see why▾
Why this is wrong here
Resource pooling refers to the provider's computing resources being pooled to serve multiple customers, with physical and virtual resources dynamically assigned. This scenario focuses on employees accessing applications from any device via a standard web browser, which demonstrates broad network access, not resource pooling.
★ When this WOULD be the correct answer
A company wants to ensure that its cloud provider can dynamically assign compute resources to different departments based on demand, without the departments needing to know the exact physical location of the resources. This would best demonstrate resource pooling.
Why candidates choose this
Candidates may confuse resource pooling with the idea of sharing resources across many users (employees), but the key here is the access method (web browser from anywhere), not how the provider manages resources behind the scenes.
✗Rapid elasticityWrong answer — click to see why▾
Why this is wrong here
Rapid elasticity refers to the ability to quickly scale resources up or down based on demand, which is not demonstrated in this scenario. The scenario focuses on employees accessing applications from various devices and locations via standard web browsers, which exemplifies broad network access, not elasticity.
★ When this WOULD be the correct answer
A company experiences unpredictable spikes in traffic to its e-commerce website during flash sales. The cloud automatically provisions additional servers to handle the load and deprovisions them when traffic subsides. This scenario would best demonstrate rapid elasticity.
Why candidates choose this
Candidates may confuse the ability to access resources from anywhere (broad network access) with the ability to scale resources quickly (rapid elasticity), especially when the scenario involves many users and devices, which might imply varying demand.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse 'broad network access' with 'resource pooling' because both involve multi-device scenarios, but broad network access is specifically about the accessibility of services over the internet using standard protocols, not about how resources are shared among tenants.
Trap categories for this question
Scenario analysis trap
Measured service refers to the capability of cloud systems to automatically control and optimize resource usage by metering usage (e.g., storage, processing, bandwidth). This enables pay-as-you-go billing. The scenario does not describe metering or billing, so this is incorrect.
Detailed technical explanation
How to think about this question
Broad network access is defined in 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 means AWS services like Amazon S3, API Gateway, and CloudFront expose HTTPS endpoints (port 443) that any modern browser can reach, eliminating the need for proprietary VPN clients or leased-line hardware. A subtle behavior is that while broad network access enables internet-based connectivity, it does not guarantee low latency or high throughput—those depend on the underlying network path and AWS edge locations.
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.
