tick time is 2000 ms, and initLimit is the config taken into account when establishing a connection to Zookeeper, so the answer is 2000 * 20 = 40000 ms = 40s

COUNT and JOIN don't write to Kafka, just read data.

Wait, are you sure about that? I thought only C does that.

Definitely D! Those queries create new streams/tables.

I thought CREATE TABLE WITH also writes to Kafka?

I'm pretty confident that the correct answer is D, but I might have mixed up some details from similar practice questions.

SHOW STREAMS and EXPLAIN statements definitely don't write to Kafka, but I can't recall if CREATE STREAM WITH does.

I remember practicing with KSQL queries, and I feel like COUNT and JOIN don't actually write to Kafka, but I could be wrong.

I think CREATE STREAM AS SELECT and CREATE TABLE AS SELECT are the ones that write to Kafka, but I'm not entirely sure.

I'm pretty confident that the CREATE STREAM/TABLE AS SELECT statements are the right answers here. Those are the KSQL queries that actually produce new Kafka topics as output. The other options are more for administrative tasks.

Okay, I've got it! The CREATE STREAM AS SELECT and CREATE TABLE AS SELECT statements are the ones that write the results of a KSQL query directly to a Kafka topic. The other options are more for managing and inspecting KSQL, not for writing data.

Hmm, I'm a bit confused on this one. I know KSQL is used for stream processing, but I'm not entirely sure which specific statements actually write to Kafka. I'll have to think this through carefully.

I think the key here is to focus on the KSQL statements that actually write data to Kafka topics. The options with "CREATE STREAM AS SELECT" and "CREATE TABLE AS SELECT" seem like the most likely candidates.

I remember practicing a question similar to this, and I think normalization is about breaking down relations, not rejoining them.

Hmm, I'm not 100% sure about this. I know the GDPR has specific timelines, but I can't quite remember the details. I'll have to review my notes and try to reason through the options carefully.

Okay, let me think this through step-by-step. The key is to focus on the details in the output and match them to the statements.

D) CREATE STREAM AS SELECT and CREATE TABLE AS SELECT - That's the correct answer, I'm sure of it. Now if only I could remember how to spell 'KSQL' on the exam...

I'm going to go with D) CREATE STREAM AS SELECT and CREATE TABLE AS SELECT. It's the only option that mentions actually writing to Kafka, which is what the question is asking about. Unless, of course, the exam writers are trying to pull a fast one on us...

B) SHOW STREAMS and EXPLAIN statements? Really? I doubt those would write anything to Kafka. This exam is trying to trick us!

I'm going with C) CREATE STREAM WITH and CREATE TABLE WITH . Seems like the most straightforward way to create new Kafka topics through KSQL.
DE

Oh, I see. So C) CREATE STREAM WITH and CREATE TABLE WITH are the ones that actually write to Kafka.

No, those queries are used to create streams and tables based on existing topics, not to write to Kafka directly.

I think D) CREATE STREAM AS SELECT and CREATE TABLE AS SELECT also write to Kafka.

That's a good choice. Those queries are indeed used to create new Kafka topics.

D) CREATE STREAM AS SELECT and CREATE TABLE AS SELECT - That's the only way to write to Kafka through KSQL, right? The other options are more for managing and inspecting KSQL objects.
