By default, what do Kafka broker network connections have?

Show Suggested Answer Hide Answer
Suggested Answer: A

By default, Kafka brokers use the PLAINTEXT protocol for network communication. This means:

No encryption -- data is sent in plain text.

No authentication -- any client can connect without verifying identity.

No authorization -- there are no access control checks by default.

Security features like TLS, SASL, and ACLs must be explicitly configured.

I remember something about default settings allowing plaintext connections unless specified otherwise.

I think Kafka broker connections are secured by default, but I'm not entirely sure if that's true for all configurations.

I'm drawing a blank on the default for Kafka broker network connections. I know Kafka has a lot of moving parts, so I'll need to carefully consider the different network-related settings it has.

The default for Kafka broker network connections? I'm pretty confident it has to do with the protocol or port they use, but I can't recall the specifics off the top of my head. I'll have to think it through step-by-step.

Okay, for Kafka broker network connections, the default is probably something related to security or authentication. I'll need to review my notes on Kafka configuration to be sure.

Hmm, I know Kafka has a lot of settings and configurations, so the default for network connections could be anything. I'll need to think this through carefully.

I think Kafka broker network connections have some kind of default configuration, but I'm not totally sure what that would be.
