But what about B) IPSec? It’s secure too.

Not sure about that, I thought IPSec was more common for encryption.

I’m confused about ECC; I know it’s related to encryption, but I don’t think it’s specifically for networking communications like the others.

I feel like I’ve seen a similar question before, and I think VPNs might require some configuration on the endpoints, so I’m leaning towards TLS.

I think it's Transport Layer Security (TLS) because it can encrypt data in transit without needing changes on the endpoints.

TLS seems like the most likely answer since it's a common encryption protocol used in web communications. But I'll double-check the other options just to be sure.

Okay, I think I've got a strategy here. I'll eliminate the options that require configuration on the IoT devices, and then evaluate the remaining choices.

Hmm, I'm a bit confused on the "without requiring any configuration on IoT endpoints" part. I'll have to carefully consider the details of each option.
