Salesforce Marketing cloud recently announced the retirement of the TLS 1.0 based connections effective early August this year, and they published a Knowledge Article with useful information and some guidelines for the matter, but in that article they talk about integrations with the API (REST/SOAP) but not with the SDKs (even though, that's just a wrapper of the afore mentioned).

I'm using the FuelSDK-Java to integrate my backend with Salesforce Marketing Cloud and i would like to check which TLS protocol it is using to connect with.

How/where can I check that?

Is not the Fuel-SDK what we should look at but the JDK version we are using.

Java 8 use TLS1.2 as default for connections, and i double checked it with wireshark while doing request to SFMC using the fuel-sdk for java.
