[Full-Version] 2026 New CCDAK Actual Exam Dumps, Confluent Practice Test [Q48-Q66]

Q48. Your application is consuming from a topic configured with a deserializer.
It needs to be resilient to badly formatted records (“poison pills”). You surround the poll() call with a try/catch for RecordDeserializationException.
You need to log the bad record, skip it, and continue processing.
Which action should you take in the catch block?

Q49. Which two statements are correct when assigning partitions to the consumers in a consumer group using the assign() API?
(Select two.)

Q50. You want to connect with username and password to a secured Kafka cluster that has SSL encryption.
Which properties must your client include?

Q51. A consumer wants to read messages from partitions 0 and 1 of a topic topic1. Code snippet is shown below.
consumer.subscribe(Arrays.asList(“topic1”));
List<TopicPartition> pc = new ArrayList<>();
pc.add(new PartitionTopic(“topic1”, 0));
pc.add(new PartitionTopic(“topic1”, 1));
consumer.assign(pc);

Q52. What is true about replicas ?

Q53. Select all the way for one consumer to subscribe simultaneously to the following topics – topic.history, topic.
sports, topic.politics? (select two)

Q54. You create a producer that writes messages about bank account transactions from tens of thousands of different customers into a topic.
* Your consumers must process these messages with low latency and minimize consumer lag
* Processing takes ~6x longer than producing
* Transactions for each bank account must be processedin orderWhich strategy should you use?

Q55. What are two examples of performance metrics?
(Select two.)

Q56. Which of the following is not an Avro primitive type?

Q57. You create a topic named loT-Data with 10 partitions and replication factor of three.
A producer sends 1 MB messages compressed with Gzip.
Which two statements are true in this scenario?
(Select two.)

Q58. You are experiencing low throughput from a Java producer. You monitor the Kafka metrics and notice that the metrics for that producer show low I/O thread ratio and low I/O thread wait ratio.
What is most likely the cause of the slow producer performance?

Q59. Which tool can you use to modify the replication factor of an existing topic?

Q60. An application is consuming messages from Kafka. You observe partitions being frequently reassigned to the consumer group from the application logs.
Which factors may be contributing to this? (Choose 2.)

Q61. When using the Confluent Kafka Distribution, where does the schema registry reside?

Q62. When running a ksqlDB for connectors, what does the IF NOT EXISTS clause do?

Q63. A stream processing application is tracking the user activity of online shopping carts. The application tracks items added to the cart, items removed from the cart, and items ordered from the cart throughout the day for each user.
You need to capture the data to identify possible periods of user inactivity.
Which type of Kafka Streams window should you use?

Q64. A consumer wants to read messages from a specific partition of a topic. How can this be achieved?

Q65. Which actions will trigger partition rebalance for a consumer group? (select three)

Q66. A consumer has auto.offset.reset=latest, and the topic partition currently has data for offsets going from 45 to
2311. The consumer group never committed offsets for the topic before. Where will the consumer read from?
