Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Broad network access

  Why it's wrong here

  Broad network access describes the ability to access cloud services over the network using standard protocols (e.g., HTTPS, SSH) from heterogeneous client platforms such as laptops, mobile phones, and workstations. While this characteristic is essential for any cloud deployment, it focuses purely on the transport and accessibility layer—not on the mechanism by which a user independently provisions computational resources. The question asks about a characteristic that enables a user to provision resources automatically, which is a distinct capability separate from mere network reachability.

• ✗

  Measured service

  Why it's wrong here

  Measured service is the cloud characteristic that meters resource usage (compute, storage, bandwidth, and active user accounts) to provide transparency for both the provider and consumer. It enables pay-per-use billing and optimization, but it does not, by itself, allow a user to request or spin up new resources without provider involvement. The act of provisioning is a separate, user-triggered action; metering only happens after resources are allocated and consumed.

• ✗

  Resource pooling

  Why it's wrong here

  Resource pooling allows a cloud provider to serve multiple consumers from shared physical and virtual resources that can be dynamically assigned and reassigned according to demand. This multi-tenancy model improves economies of scale but is fundamentally an infrastructure-level architectural characteristic. It does not give the user the direct ability to self-provision; rather, it enables the provider to manage and allocate resources behind the scenes, which is distinct from the user-facing, on-demand provisioning capability.

• ✓

  On-demand self-service

  Why this is correct

  On-demand self-service is the cloud characteristic that lets a user directly provision and configure computing resources—such as virtual machines, storage, and applications—through a web portal or API, without requiring manual approval or interaction with the provider's staff. This unmediated, automated provisioning is the fundamental enabler of the question's described action, as it gives the user immediate control over resource creation and scaling. It is the defining feature that differentiates cloud computing from traditional IT procurement, where human intervention and long lead times are common.
