Final answer:
The DCM/DFA Trafficking and Reporting API allows users to upload conversions and customize reporting but does not handle downloading data transfer log files or customizing verification alerts.
Step-by-step explanation:
The DCM/DFA Trafficking and Reporting API can directly accomplish two specific tasks from the options provided. The API, which stands for DoubleClick Campaign Manager/DoubleClick for Advertisers, is designed to support campaign management and reporting at scale. One of its capabilities includes the option to upload conversions, which is essential for digital marketing and advertising campaigns.
Another feature is to customize reporting, allowing users to pull various reports based on their specifications and requirements. However, it does not natively handle tasks like downloading data transfer log files or customizing verification alerts; these might require additional tools or services.
