Kafka - Monitoring and Operations

Given this command output snippet from Kafka monitoring, what does it indicate?

Partition 0 Leader: 1
Partition 0 ISR: 1,2
Partition 1 Leader: 2
Partition 1 ISR: 2

APartition 1 has no in-sync replicas, risking data loss.

BAll partitions have healthy leaders and in-sync replicas.

CPartition 0 leader is down because ISR is missing.

DKafka cluster has no active brokers.

Step-by-Step Solution

Solution:

Step 1: Understand Leader and ISR meaning
Leader is the broker handling writes; ISR (in-sync replicas) are replicas up to date with leader.
Step 2: Analyze the output
Partition 0 leader is broker 1 with ISR 1 and 2, both in sync. Partition 1 leader is 2 with ISR 2, also in sync.
Final Answer:
All partitions have healthy leaders and in-sync replicas. -> Option B
Quick Check:
Leader and ISR present = healthy partitions [OK]

Quick Trick: Leader and ISR presence means healthy partitions [OK]
