When using license pools, volume allocations apply to indexers. A license pool is a group of indexers that share a certain amount of daily indexing volume. The license pool specifies how much data each indexer can index per day, as well as which indexes are available for each indexer. Therefore, option A is the correct answer.

Reference:
When creating an HTTP event, the request header must include a token that identifies the HTTP Event Collector (HEC) endpoint. The token is a 32-character hexadecimal string that is generated when the HEC endpoint is created. The token is used to authenticate the request and route the event data to the correct index. Therefore, option B is the correct answer. Reference: Splunk Enterprise Certified Admin | Splunk, [About HTTP Event Collector - Splunk Documentation]
