Confluent CCDAK Exam - Topic 1 Question 51 Discussion

Actual exam question for Confluent's CCDAK exam

Question #: 51
Topic #: 1

You are using JDBC source connector to copy data from 3 tables to three Kafka topics. There is one connector created with max.tasks equal to 2 deployed on a cluster of 3 workers. How many tasks are launched?

Show Suggested Answer

Suggested Answer: A

Since Confluent 5.4.0, Avro 1.9.1 is used. Since default value was added to enum complex type , the schema resolution changed from:

(<1.9.1) if both are enums:** if the writer's symbol is not present in the reader's enum, then an error is signalled. **(>=1.9.1) if both are enums:

if the writer's symbol is not present in the reader's enum and the reader has a default value, then that value is used, otherwise an error is signalled.

I’m surprised it’s not more with 3 workers!

I think it’s 2 too, makes sense.

Wait, why not 3? There are 3 tables!

Totally agree, max.tasks limits it.

Only 2 tasks will be launched.

Wait, could it be that the number of tasks is limited by the number of tables too? I feel like I need to double-check that.

I practiced a similar question where the number of tasks was equal to the max.tasks, so I’m leaning towards 2 as the answer.

I'm not entirely sure, but I remember something about tasks being distributed across workers. Does that mean we could have fewer tasks than workers?

I think the max.tasks setting determines how many tasks can run, so it should be 2, right?

I'm pretty confident that the answer is 2 tasks launched. The max.tasks setting limits the number of tasks, and with 3 workers, the connector will launch up to 2 tasks.

Okay, let me break this down step-by-step. We have 1 connector with max.tasks=2, and 3 workers. So the number of tasks launched should be the minimum of those two values, which is 2.

Hmm, I'm a bit confused about how the max.tasks setting interacts with the number of workers. I'll need to review the JDBC source connector documentation to make sure I understand this properly.

This seems straightforward. I'll think through the max.tasks setting and the number of workers to determine the number of tasks launched.

I'm feeling pretty confident about this one. The index level that limits the logical operators is IndexNone, so I'll select option A.

Hmm, this is a tricky one. I'm a little unsure about the exact order of the steps in the Procure to Pay cycle. I'll need to think this through carefully.

I remember DMVPN being flexible for dynamic tunnel creation, but I'm not sure if it supports multicast effectively.

I feel like the scatter plot option could help us see relationships, but both scatter and histograms might give different perspectives.

This seems like a straightforward question. I think the key is to identify services that can handle session state data in a highly available way.

Wait, so the connector is deployed on a cluster of 3 workers, but the max.tasks is set to 2? That's like putting a Ferrari engine in a Prius, what's the point?
