On this page
This lesson matters because many Kafka admin questions are really cluster-state questions in disguise. The exam wants you to know which broker role or partition state is actually responsible for what you are seeing.
Cluster-role chooser
If the stem is mostly about…
Strongest first focus
metadata leadership and cluster state changes
controller behavior
write target for one partition
leader replica
replica catch-up health
follower state and ISR membership
scaling read or write work
partitions and replication design
What the exam is really testing
If the code or scenario shows…
Strong reading
controller instability
cluster coordination is under test
lagging followers
replication health is under test
more consumers than parallel work
partition count may be the constraint
leadership movement
partition availability and safety are under test
Common traps
Trap
Better rule
