Question 162 of 1,024

Cloud Concepts →easyMultiple ChoiceObjective-mapped

Quick Answer

The answer is broad network access. This is correct because the scenario directly aligns with the NIST definition of broad network access as a core cloud computing characteristic: resources are available over the network and accessed through standard mechanisms like HTTP/HTTPS, enabling use by heterogeneous thin or thick client platforms—here, desktops, laptops, tablets, and smartphones—without any proprietary software or additional configuration. On the AWS Certified Cloud Practitioner CLF-C02 exam, this concept tests your understanding of how cloud services are universally reachable from any internet-connected device using standard browsers, often appearing in scenario-based questions that contrast it with other characteristics like rapid elasticity or measured service. A common trap is confusing broad network access with resource pooling or on-demand self-service; remember that broad network access is specifically about ubiquitous, device-agnostic connectivity over the network. Memory tip: think “any device, any browser, any network” to lock in the definition.

CLF-C02 Cloud Concepts Practice Question

This CLF-C02 practice question tests your understanding of cloud concepts. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 has migrated its customer-facing web application to AWS. The application is deployed on Amazon EC2 instances behind an Application Load Balancer. The company's customers access the application from various devices—desktop computers, laptops, tablets, and smartphones—using standard web browsers without any additional configuration or proprietary software. The ability for customers to reach the application over the internet from any device with a standard browser best demonstrates which essential characteristic of cloud computing?

Clue words in this question

A
On-demand self-service
Why wrong: On-demand self-service allows users to provision computing resources without human interaction. The scenario describes accessing an already-deployed application, not provisioning resources, so this is not the correct characteristic.
B
Broad network access
Broad network access means cloud resources are accessible over the network via standard mechanisms (e.g., HTTPS) from a wide range of devices. The question describes customers using standard web browsers on various devices to reach the application, which is a direct example of broad network access.
C
Resource pooling
Why wrong: Resource pooling refers to the provider's computing resources being pooled to serve multiple consumers, where the customer has no knowledge of the exact physical location. The scenario does not discuss multi-tenancy or location independence, so resource pooling is not the best fit.
D
Rapid elasticity
Why wrong: Rapid elasticity is the ability to automatically scale resources up or down based on demand. The question focuses on access from various devices, not on scaling, so rapid elasticity is not demonstrated here.

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 customers accessing the application from various devices (desktops, laptops, tablets, smartphones) using standard web browsers over the internet without any proprietary software. This directly matches the NIST definition of broad network access: resources are available over the network and accessed through standard mechanisms (e.g., HTTP/HTTPS) that promote use by heterogeneous thin or thick client platforms.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✗
On-demand self-service
Why it's wrong here
On-demand self-service allows users to provision computing resources without human interaction. The scenario describes accessing an already-deployed application, not provisioning resources, so this is not the correct characteristic.

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 distinction is that broad network access is about heterogeneous device reachability via standard protocols, while on-demand self-service is about automated resource provisioning without provider intervention.

Trap categories for this question

Scenario analysis trap
On-demand self-service allows users to provision computing resources without human interaction. The scenario describes accessing an already-deployed application, not provisioning resources, so this is not the correct characteristic.

Detailed technical explanation

How to think about this question

Broad network access relies on standard network protocols such as HTTP/1.1 (RFC 7230), HTTPS (TLS 1.2/1.3), and WebSocket (RFC 6455) to ensure interoperability across diverse client platforms. In practice, this means the Application Load Balancer terminates TLS connections and forwards HTTP/HTTPS traffic to EC2 instances, allowing any device with a standards-compliant browser to connect without client-side plugins or custom VPNs. A subtle behavior is that ALB supports HTTP/2 (RFC 7540) which reduces latency for mobile clients by multiplexing requests over a single TCP connection.

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.
