[Solved] Why does Docker Swarm use a Raft consensus algorithm for manager nodes? — Ans: To ensure consistent state and fault tolerance among managers | Docker

Docker - Swarm

Why does Docker Swarm use a Raft consensus algorithm for manager nodes?

ATo encrypt service communication automatically

BTo ensure consistent state and fault tolerance among managers

CTo balance network traffic between worker nodes

DTo speed up container startup times

Step-by-Step Solution

Solution:

Step 1: Understand Raft's purpose
Raft is a consensus algorithm that keeps manager nodes in sync and handles failures.
Step 2: Analyze other options
Raft does not affect container startup speed, network traffic balancing, or encryption.
Final Answer:
To ensure consistent state and fault tolerance among managers -> Option B
Quick Check:
Raft = consensus for manager state consistency [OK]

Quick Trick: Raft keeps managers consistent and fault tolerant [OK]
