A public cloud administrator needs to implement a mechanism to monitor the expense of the company's cloud resources. Which of the following options will allow the administrator to execute this task fa

Daily expense reports must be configured and scheduled, and they provide only periodic snapshots rather than continuous visibility, making this a slower and less comprehensive approach.

Custom budget threshold notifications require the administrator to first define thresholds and configure alerting rules, adding setup overhead and providing reactive rather than holistic expense monitoring.

Using an API to collect expense data requires writing, testing, and maintaining custom code, which represents significant development effort and is the slowest option.

Cloud-native financial management tools such as AWS Cost Explorer, Azure Cost Management, or third-party platforms like CloudHealth are purpose-built to aggregate, visualize, and report on cloud spending across all resources. They require minimal configuration to become operational and provide immediate visibility. No custom development or manual processes are needed, satisfying both the speed and minimal-effort requirements.
