easy📝 Conceptual Q1 of 15
Kafka - Multi-Datacenter and Replication
How does deploying Kafka brokers across multiple datacenters contribute to system uptime?
AIt decreases message throughput
BIt reduces the number of topics needed
CIt eliminates the need for replication
DIt prevents total service disruption if one datacenter fails
Step-by-Step Solution
Solution:

  1. Step 1: Understand failure scenarios

    If one datacenter fails, brokers in other datacenters can continue serving requests.

  2. Step 2: Role of multiple datacenters

    Having brokers in multiple locations ensures redundancy and fault tolerance.

  3. Final Answer:

    It prevents total service disruption if one datacenter fails -> Option D

  4. Quick Check:

    Multiple datacenters improve availability by avoiding single points of failure [OK]
Quick Trick: Multiple datacenters avoid single points of failure [OK]
Common Mistakes:
MISTAKES
  • Thinking replication is unnecessary with multiple datacenters
  • Assuming throughput always increases with more datacenters
