Is it true that Splunk Cloud does not support UDP?

The correct response is that Splunk Cloud does not support UDP, making the statement true. Splunk Cloud is designed to prioritize security, scalability, and reliability, which influence its data ingestion methods. UDP, being a connectionless protocol, does not guarantee the delivery of packets and poses a risk for data loss and integrity. This is fundamentally at odds with the expectations for data reliability in cloud environments, where ensuring data is received accurately and consistently is crucial.

In contrast, TCP is the protocol of choice within Splunk Cloud, providing connection-oriented communication that allows for reliable data transmission. This means that when deploying Splunk in the cloud, users must use alternative methods for data ingestion that do not involve UDP, thus ensuring high availability and data fidelity.

The other options, such as user settings, region-specific restrictions, or the notion that UDP is partially supported, are not accurate as Splunk Cloud maintains a firm stance on not incorporating UDP in its supported ingestion methods.
