Missing leading slash making path relative

Including spaces in directory names

The log directory path must be an absolute path without spaces.

💡 Hint

Common Mistakes

Setting replication factor higher than number of brokers

Using 1 partition which limits parallelism

Common default settings are 3 partitions and replication factor of 2 for fault tolerance.

5fill in blank

hard

Fill all three blanks to configure the broker's advertised listeners and log retention time.

Kafka

advertised.listeners=[1]
listener.security.protocol.map=[2]
log.retention.hours=[3]

Drag options to blanks, or click blank then click option'

APLAINTEXT://broker1:9092

BPLAINTEXT:PLAINTEXT

C168

DSSL

Attempts:

💡 Hint

Common Mistakes

Using only hostname without protocol in advertised.listeners

Setting retention time too low or too high without reason

The advertised listener must include protocol and address, the protocol map defines security, and retention is in hours (168 = 7 days).
