easy📝 Conceptual Q2 of 15
Kafka - Multi-Datacenter and Replication
What is the main benefit of replicating Kafka data across multiple datacenters?
AIt improves data availability and fault tolerance
BIt makes Kafka run only in one datacenter
CIt guarantees data is lost if one datacenter fails
DIt reduces network traffic between datacenters
Step-by-Step Solution
Solution:

  1. Step 1: Understand replication in Kafka

    Replication copies data to multiple datacenters to protect against failures.

  2. Step 2: Identify the benefit of replication

    Replication improves availability and fault tolerance by having multiple copies.

  3. Final Answer:

    It improves data availability and fault tolerance -> Option A

  4. Quick Check:

    Replication = Availability + Fault tolerance [OK]
Quick Trick: Replication means multiple copies for safety [OK]
Common Mistakes:
MISTAKES
  • Assuming replication causes data loss
  • Thinking replication limits Kafka to one datacenter
  • Believing replication reduces network traffic
