The correct answer is A, B, and D, because they are all items that can be configured in inputs.conf. Inputs.conf is a configuration file that defines how Splunk ingests data from various sources, such as files, directories, network ports, scripts, or modular inputs. A modular input written in Python is a type of input that allows Splunk to ingest data from a custom source using a Python script. A file input monitoring a JSON file is a type of input that allows Splunk to monitor a file or directory for new or updated data in JSON format. An HTTP Event Collector as receiver of data from an app is a type of input that allows Splunk to receive data from an app via HTTP or HTTPS requests. A custom search command written in Python is not an item that can be configured in inputs.conf, but in commands.conf.
