CLF-C02 Cloud Concepts Practice Question
A company has deployed a customer relationship management (CRM) application on AWS. Sales representatives use the application from their office laptops, company-issued tablets, and personal smartphones. They access the application securely through a web browser using HTTPS from any location, including client sites and home offices. This capability is an example of which essential characteristic of cloud computing?
⚠ Common exam trap
It's easy for candidates to confuse broad network access with rapid elasticity because both involve 'access from anywhere' or 'scalability,' but the key distinction is that broad network access is about device and protocol heterogeneity, not automatic scaling.
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
Broad network access is the correct answer because the scenario describes the ability to access the CRM application from various devices (laptops, tablets, smartphones) over the network using standard protocols (HTTPS). This aligns with the NIST definition of broad network access, which states that capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Rapid elasticity
Why it's wrong here
Rapid elasticity refers to the ability to automatically scale resources up or down based on demand, such as adding EC2 instances during traffic spikes. The scenario does not involve scaling; it focuses on ubiquitous access from different devices and locations.
When this WOULD be correct
A question describing a CRM application that automatically adds or removes compute capacity in response to fluctuating user load, such as during a sales campaign, would make rapid elasticity the correct answer.
- ✗
Measured service
Why it's wrong here
Measured service refers to the cloud provider's ability to monitor, meter, and bill customers for their exact resource consumption, typically on a pay-as-you-go basis. The scenario describes sales representatives connecting to the CRM application from various devices and locations, which illustrates ubiquitous network access rather than usage-based metering. While AWS does employ measured service for billing, it is not the characteristic being demonstrated here.
When this WOULD be correct
A question describing a cloud provider that charges based on the amount of storage consumed or the number of API calls made, and the provider monitors and reports usage for billing purposes, would make 'Measured service' the correct answer.
- ✓
Broad network access
Why this is correct
Broad network access enables cloud resources to be accessed over the network via standard protocols (e.g., HTTPS) from a wide range of client devices such as laptops, tablets, and smartphones. The sales representatives accessing the CRM application from multiple device types and locations directly demonstrates this characteristic.
- ✗
Resource pooling
Why it's wrong here
Resource pooling means that the provider's computing resources are pooled to serve multiple customers using a multi-tenant model, with physical and virtual resources dynamically assigned. The scenario does not mention multi-tenancy or resource sharing; it focuses on user access methods.
When this WOULD be correct
A question describing a scenario where multiple customers share the same physical infrastructure, with resources dynamically allocated and reallocated based on demand, and the customer has no control over the exact location of the resources (e.g., 'A company uses a public cloud where its virtual machines run on shared hardware without knowing the physical server location').
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 enables cloud resources to be accessed over the network via standard protocols (e.g., HTTPS) from a wide range of client devices such as laptops, tablets, and smartphones. The sales representatives accessing the CRM application from multiple device types and locations directly demonstrates this characteristic.
✗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, not to accessing the application from multiple device types and locations over HTTPS.
★ When this WOULD be the correct answer
A question describing a CRM application that automatically adds or removes compute capacity in response to fluctuating user load, such as during a sales campaign, would make rapid elasticity the correct answer.
Why candidates choose this
Candidates may confuse the ability to access from many devices with the concept of scaling, or they might think 'elastic' refers to flexible access rather than resource provisioning.
✗Measured serviceWrong answer — click to see why▾
Why this is wrong here
Measured service refers to the capability of cloud systems to automatically control and optimize resource usage by metering it, which is not demonstrated by the scenario of accessing a CRM application from various devices and locations via HTTPS.
★ When this WOULD be the correct answer
A question describing a cloud provider that charges based on the amount of storage consumed or the number of API calls made, and the provider monitors and reports usage for billing purposes, would make 'Measured service' the correct answer.
Why candidates choose this
Candidates may confuse the ability to access services from anywhere with the idea that usage is being measured or metered, especially since HTTPS access implies some form of tracking or logging.
✗Resource poolingWrong answer — click to see why▾
Why this is wrong here
Resource pooling refers to the provider's multi-tenant model where computing resources are pooled to serve multiple customers, with physical and virtual resources dynamically assigned. The question describes access from various devices and locations, which is about network access, not resource pooling.
★ When this WOULD be the correct answer
A question describing a scenario where multiple customers share the same physical infrastructure, with resources dynamically allocated and reallocated based on demand, and the customer has no control over the exact location of the resources (e.g., 'A company uses a public cloud where its virtual machines run on shared hardware without knowing the physical server location').
Why candidates choose this
Candidates may confuse 'broad network access' with 'resource pooling' because both involve multiple users and devices, but resource pooling focuses on the provider's infrastructure sharing, not the user's ability to access from anywhere.

These questions test the same concept from different angles. Work through them to make sure you can recognise it however the exam phrases it.
Variation 1. 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?
easy- A.Resource pooling
- B.Measured service
- ✓ C.Broad network access
- D.Rapid elasticity
Why C: 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.
