Which cloud computing characteristic enables consumers to request resources using a service
catalog through a web-based user interface?

A.
On-demand self-service

B.
Broad network access

C.
Metered services

D.
Catalog management

Explanation:
On-Demand Self-Service
A consumer can unilaterally provision computing capabilities, such as server time and network
storage, as needed automatically without requiring human interaction with each service provider.
A cloud service provider publishes a service catalogue, which contains information about all cloud
services available to consumers. The service catalogue includes information about service
attributes, prices, and request processes. Consumers view the service catalogue via a web-based
user interface and use it to request for a service. Consumers can either leverage the “ready-touse” services or change a few service parameters to customize the services.
