The red outlined numbers are called offsets, the offset points to:

• the last message a consumer read from a partition

• the first message a consumer should read when it fetches a new batch of messages

Kafka is a distributed system. The nodes or servers in Kafka are also called :

(a)  

If a topic has a replication factor of 3, what maximum number of brokers can be stopped without impacting the topic availability?

• 1

• 2

• 3

To get acknowledgment of writes to only the partition leader, we need to use the config:

• acks=0

• acks=1

• acks=all

The Kafka Consumer offsets are stored in

• Kafka

• Zookeeper

Kafka messages can never be

• deleted

• added twice

• updated

Kafka guarantees the message order

• within a partition

• within a topic

• no guarantees

Every broker

• Contains all topics and partitions 

• Contains a subset of topics and portions
