NO.32 A broker in the Kafka cluster is currently acting as the Controller.
Which statement is correct?

It can have topic partitions.

It is given precedence for replication to and from replica followers.

All consumers are allowed to fetch messages only from this server.

It is responsible for sending leader information to all producers.

The Controller broker is a regular broker that also takes on additional responsibilities for managing cluster metadata, such as leader elections and partition assignments. It still hosts topic partitions and participates in replication like any other broker.

NO.33 Your Kafka cluster has four brokers. The topic t1 on the cluster has two partitions, and it has a replication factor of three. You create a Consumer Group with four consumers, which subscribes to t1.
In the scenario above, how many Controllers are in the Kafka cluster?

One

two

three

Four

In a Kafka cluster, only one broker acts as the Controller at any given time. The Controller is responsible for managing cluster metadata, such as partition leadership and broker status. Even if the cluster has multiple brokers (in this case, four), only one is elected as the Controller, and others serve as regular brokers. If the current Controller fails, another broker is automatically elected to take its place.

NO.34 Which statements are correct about partitions? (Choose two.)

A partition in Kafka will be represented by a single segment on a disk.

A partition is comprised of one or more segments on a disk.

All partition segments reside in a single directory on a broker disk.

A partition size is determined after the largest segment on a disk.

NO.35 What is the relationship between topics and partitions? (Choose two.)

Atopic always has one partition.

Atopic may have more than one partition.

A partition is always linked to a single topic.

A partition may have more than one topic.

There is no relationship between topics and partitions.

Kafka topics are split into one or more partitions to enable parallelism and scalability.
Each partition belongs to exactly one topic; it cannot span multiple topics.

NO.36 By default, what do Kafka broker network connections have?

No encryption, no authentication and no authorization

Encryption, but no authentication or authorization

No encryption, no authorization, but have authentication

Encryption and authentication, but no authorization

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.

NO.37 When using Kafka ACLs, when is the resource authorization checked?

Each time the resource is accessed.

The initial time the resource is accessed.

Each time the resource is accessed within the configured authorization interval.

When the client connection is first established.

Kafka ACLs (Access Control Lists) perform authorization checks every time a client attempts to access a resource (e.g., topic, consumer group). This ensures continuous enforcement of permissions, not just at connection time or intervals. This approach provides fine-grained security, preventing unauthorized actions at any time during a session.

NO.38 Which technology can be used to perform event stream processing? (Choose two.)

Confluent Schema Registry

Apache Kafka Streams

Confluent ksqlDB

Confluent Replicator

Kafka Streams is a client library for building real-time applications that process and analyze data stored in Kafka.
ksqlDB enables event stream processing using SQL-like queries, allowing real-time transformation and analysis of Kafka topics.

NO.39 Where are Apache Kafka Access Control Lists stored’?

Broker

ZooKeeper

Schema Registry

Connect

In Apache Kafka (open-source), Access Control Lists (ACLs) are stored in ZooKeeper. Kafka brokers retrieve and enforce ACLs from ZooKeeper at runtime.

NO.40 Kafka Connect is running on a two node cluster in distributed mode. The connector is a source connector that pulls data from Postgres tables (users/payment/orders), writes to topics with two partitions, and with replication factor two. The development team notices that the data is lagging behind.
What should be done to reduce the data lag*?
The Connector definition is listed below:
{
“name”: “confluent-postgresql-source”,
“connector class”: “PostgresSource”,
“topic.prefix”: “postgresql_”,
& nbsp;& nbsp;& nbsp;…
“db.name”: “postgres”,
“table.whitelist”: “users.payment.orders”,
“timestamp.column.name”: “created_at”,
“output.data format”: “JSON”,
“db.timezone”: “UTC”,
“tasks.max”: “1”
}

Increase the number of Connect Nodes.

Increase the number of Connect Tasks (tasks max value).

Increase the number of partitions.

Increase the replication factor and increase the number of Connect Tasks.

The connector is currently configured with “tasks.max”: “1”, which means only one task is handling all tables (users, payment, orders). This can create a bottleneck and lead to lag. Increasing tasks.max allows Kafka Connect to parallelize work across multiple tasks, which can pull data from different tables concurrently and reduce lag.

NO.41 What are benefits to gracefully shutting down brokers? (Choose two.)

It will sync all its logs to disk to avoid needing to do any log recovery when it restarts.

It will migrate any partitions the server is the leader for to other replicas prior to shutting down.

It will automatically re-elect leaders on restart.

It will balance the partitions across brokers before restarting.

A graceful shutdown ensures that logs are flushed to disk, minimizing recovery time during restart.
Kafka performs controlled leader migration during a graceful shutdown to avoid disruption and ensure availability.

NO.42 Which model does Kafka use for consumers?

Push

Publish

Pull

Enrollment

Kafka uses a pull model for consumers, where consumers poll the broker to retrieve messages at their own pace. This model gives consumers more control over flow and backpressure, improving scalability and reliability.

NO.43 A company is setting up a log ingestion use case where they will consume logs from numerous systems. The company wants to tune Kafka for the utmost throughput.
In this scenario, what acknowledgment setting makes the most sense?

acks=0

acks=1

acks=all

acks=undefined

acks=0 provides the highest throughput because the producer does not wait for any acknowledgment from the broker. This minimizes latency and maximizes performance.
However, it comes at the cost of no durability guarantees – messages may be lost if the broker fails before writing them. This setting is suitable when throughput is critical and occasional data loss is acceptable, such as in some log ingestion use cases where logs are also stored elsewhere.

NO.44 What are important factors in sizing a ksqlDB cluster? (Choose three.)

Data Schema

Number of Queries

Number of Partitions

Data Encryption

Topic Data Retention

The complexity of the schema (number of fields, data types, etc.) affects processing and memory usage.
Each ksqlDB persistent query consumes resources (CPU, memory), so more queries require more capacity.
More partitions increase parallelism, but also resource usage, especially in scaling and state management.

NO.45 Which option is a valid Kafka Topic cleanup policy? (Choose two.)

delete

default

compact

cleanup

The delete policy deletes old log segments when they exceed the retention period or size.
The compact policy retains only the latest record for each key, enabling efficient key-based storage.

NO.46 Multiple clients are sharing a Kafka cluster.
As an administrator, how would you ensure that Kafka resources are distributed fairly to all clients?

Quotas

Consumer Groups

Rebalancing

ACLs

Kafka quotas allow administrators to control and limit the rate of data production and consumption per client (producer/consumer), ensuring fair use of broker resources among multiple clients.

NO.47 Which connector type takes data from a topic and sends it to an external data system?

Sink Connector

Source Connector

Streams Connector

SvsIog Connector

A Sink Connector reads data from a Kafka topic and writes it to an external data system, such as a database, file system, or cloud service.
