CLF-C02 Cloud Concepts Practice Question
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?
⚠ Common exam trap
It's easy for candidates to 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.
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.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Resource pooling
Why it's wrong here
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.
When this WOULD be correct
A question describing a cloud provider dynamically assigning compute and storage resources to serve multiple customers from a shared infrastructure, where customers have no control over the physical location of resources, would make resource pooling the correct answer.
- ✗
Measured service
Why it's wrong here
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.
When this WOULD be correct
A company uses AWS and receives a monthly bill based on the amount of storage consumed, number of API calls, and data transfer. This scenario would illustrate measured service, as usage is monitored and billed accordingly.
- ✓
Broad network access
Why this is correct
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.
- ✗
Rapid elasticity
Why it's wrong here
Rapid elasticity is incorrect because it specifically refers to the ability to automatically and dynamically scale computing resources up or down to match fluctuating demand, often triggered by metrics like CPU utilization or request counts. The scenario only describes employees accessing a customer relationship application from multiple device types (mobile, tablet, laptop) over the internet — a fixed access pattern, not a scaling behavior. No mention of sudden workload spikes, automatic provisioning, or resource release appears, so this characteristic is not illustrated.
When this WOULD be correct
A question describing a company that experiences sudden spikes in traffic, such as an e-commerce site during a flash sale, and needs to automatically add or remove compute instances to handle the load, would make rapid elasticity the correct answer.
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
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.
✗Resource poolingWrong answer — click to see why▾
Why this is wrong here
Resource pooling refers to serving multiple customers from shared physical resources, but the scenario emphasizes access from various devices and locations, not multi-tenancy or resource sharing.
★ When this WOULD be the correct answer
A question describing a cloud provider dynamically assigning compute and storage resources to serve multiple customers from a shared infrastructure, where customers have no control over the physical location of resources, would make resource pooling the correct answer.
Why candidates choose this
Candidates may confuse 'broad network access' with 'resource pooling' because both involve multiple users accessing shared resources, but the key here is the variety of access methods, not the pooling of resources.
✗Measured serviceWrong answer — click to see why▾
Why this is wrong here
The scenario describes access from various devices and locations via standard web browsers, which exemplifies broad network access, not measured service. Measured service involves metering and billing based on usage, which is not highlighted here.
★ When this WOULD be the correct answer
A company uses AWS and receives a monthly bill based on the amount of storage consumed, number of API calls, and data transfer. This scenario would illustrate measured service, as usage is monitored and billed accordingly.
Why candidates choose this
Candidates may confuse any cloud characteristic with measured service because they know AWS charges for usage, but the question focuses on access capability, not billing or metering.
✗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, but the scenario describes access from various devices and locations, not scaling of resources.
★ When this WOULD be the correct answer
A question describing a company that experiences sudden spikes in traffic, such as an e-commerce site during a flash sale, and needs to automatically add or remove compute instances to handle the load, would make rapid elasticity the correct answer.
Why candidates choose this
Candidates may confuse the ability to access from many devices with the cloud's ability to scale elastically, or they may think that multiple users imply dynamic resource allocation.
