Why distributed architecture ensures reliability in Kafka - Quick Recap

Recall & Review

beginner

What is distributed architecture in Kafka?

Distributed architecture means Kafka runs on many servers (called brokers) that work together to handle data and traffic.

How does Kafka use replication to improve reliability?

Kafka copies data to multiple brokers (replicas). If one broker fails, others have the data to keep the system working.

Why does having multiple brokers increase Kafka's fault tolerance?

Multiple brokers mean if one goes down, others can take over, so the system keeps running without losing data.

What role does leader election play in Kafka's reliability?

Kafka elects a leader broker for each data partition. If the leader fails, a new leader is chosen automatically to keep data available.

How does distributed architecture help Kafka handle high traffic without failure?

By spreading data and requests across many brokers, Kafka balances load and avoids overload on a single server, improving reliability.

What happens if one Kafka broker fails in a distributed setup?

A Clients must reconnect manually to a new broker

B Other brokers continue serving data without interruption

C Kafka stops working until the broker is fixed

D All data is lost immediately

In Kafka's distributed architecture, other brokers have replicas and continue serving data automatically.

Why does Kafka replicate data across brokers?

A To reduce storage space

B To slow down data processing

C To make data harder to access

D To increase data reliability and availability

Replication ensures data is safe even if some brokers fail, improving reliability.

What is the purpose of leader election in Kafka?

A To choose which broker manages a partition

B To delete old data

C To stop data replication

D To disconnect clients

Leader election assigns one broker to manage writes and reads for a partition, ensuring smooth operation.

How does distributing data across brokers help Kafka handle more users?

A It balances the load so no single broker is overwhelmed

B It makes data harder to find

C It reduces the number of messages sent

D It slows down the system

Load balancing across brokers helps Kafka scale and stay reliable under heavy use.

Which feature of Kafka helps it recover quickly from broker failures?

A Manual restart by admin

B Single broker storage

C Automatic leader election

D No replication

Automatic leader election lets Kafka pick a new leader quickly to keep data available.

Explain how Kafka's distributed architecture ensures reliability.

Think about how copies of data and multiple servers help keep Kafka running even if some parts fail.

Describe the role of replication and leader election in Kafka's reliability.

Focus on how Kafka keeps data safe and available when problems happen.
