Topic #: 4

[All CCDAK Questions]

If I want to send binary data through the REST proxy to topic "test_binary", it needs to be base64 encoded. A consumer connecting directly into the Kafka topic

A'test_binary' will receive

Bbinary data

Cavro data

Djson data

Ebase64 encoded data, it will need to decode it

Show Suggested Answer

Suggested Answer: B

On the producer side, after receiving base64 data, the REST Proxy will convert it into bytes and then send that bytes payload to Kafka. Therefore consumers reading directly from Kafka will receive binary data.

I feel like I might be mixing things up, but I thought avro data was also a possibility. Is that option C?

I practiced a similar question, and I believe the answer is E. The consumer has to decode the base64 before processing it.

I'm not entirely sure, but I remember something about binary data being sent directly without encoding. Could it be option B?

I think the consumer will receive the base64 encoded data, so it will need to decode it, right? That sounds familiar.
