Question 496 of 1,024

Cloud Concepts →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is broad network access. This scenario perfectly illustrates the cloud characteristic because the sales team can access the CRM application from diverse devices—office desktops, laptops, and personal smartphones—using only standard web browsers and internet connections, without needing proprietary client software or dedicated network links. Broad network access specifically means that cloud resources are available over the network through standard protocols (like HTTP/HTTPS) and can be consumed by a wide range of client platforms, from mobile phones to workstations. On the AWS Certified Cloud Practitioner CLF-C02 exam, this concept tests your ability to distinguish broad network access from other characteristics like resource pooling or measured service; a common trap is confusing it with "on-demand self-service," which focuses on provisioning without human interaction, not device variety. Remember the memory tip: "Broad network access = bring your own browser, any device, anywhere."

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 hosted on AWS. Sales representatives access the application from various devices—office desktops, company-issued laptops, and personal smartphones—using only standard web browsers and internet connections. No special client software or dedicated network connections are required. Which essential characteristic of cloud computing does this scenario best illustrate?

A
On-demand self-service
Why wrong: On-demand self-service refers to a consumer being able to provision computing resources (e.g., servers, storage) automatically without requiring human interaction with the service provider. The scenario describes accessing an existing application, not provisioning new resources, so this is incorrect.
B
Broad network access
Broad network access means capabilities are available over the network and accessed through standard mechanisms from a variety of client devices. The sales team uses multiple device types and standard web browsers, which is a direct example of this characteristic.
C
Resource pooling
Why wrong: Resource pooling is the provider's ability to serve multiple customers from shared physical and virtual resources, dynamically assigned according to demand. The scenario does not illustrate multi-tenancy or resource sharing; it focuses on how users connect to the service.
D
Rapid elasticity
Why wrong: Rapid elasticity refers to the ability to quickly scale resources up and down in response to demand. The scenario does not involve scaling; it simply shows users accessing an application from different devices.

Correct answer & explanation

✓

Broad network access

The scenario describes sales representatives accessing the CRM application from various devices (desktops, laptops, smartphones) using only standard web browsers and internet connections, without requiring special client software or dedicated network connections. This directly illustrates 'broad network access,' which is the ability for resources to be accessed over the network by a wide range of client platforms (e.g., mobile phones, laptops, workstations) using standard protocols (HTTP/HTTPS). The key is that the service is available from anywhere with an internet connection, not limited to a specific location or device type.

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 confuse 'broad network access' with 'on-demand self-service' because both involve user interaction, but the key differentiator is that broad network access focuses on accessibility from multiple device types over standard networks, whereas on-demand self-service is about automated provisioning without provider intervention.

Trap categories for this question

Command / output trap
Rapid elasticity refers to the ability to quickly scale resources up and down in response to demand. The scenario does not involve scaling; it simply shows users accessing an application from different devices.
Scenario analysis trap
On-demand self-service refers to a consumer being able to provision computing resources (e.g., servers, storage) automatically without requiring human interaction with the service provider. The scenario describes accessing an existing application, not provisioning new resources, so this is incorrect.

Detailed technical explanation

How to think about this question

Broad network access is defined in NIST SP 800-145 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).' Under the hood, this relies on standard protocols like HTTPS (port 443) and TLS for secure communication, and often uses RESTful APIs or WebSockets to ensure compatibility across diverse client environments. In a real-world scenario, a salesperson in a hotel using a smartphone's cellular data to access the CRM via a browser exemplifies broad network access, while a VPN requirement would violate this characteristic.

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.

A.On-demand self-service
B.Resource pooling
✓ C.Broad network access
D.Measured service

Why C: 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.
