You are designing a distributed Snake and Ladder game platform supporting thousands of concurrent games. Which approach best ensures consistent game state across servers?
hard🌍 Real-world Scenario Q9 of Q15
Step-by-Step Solution
Solution:
Step 1: Understand consistency needs
Game state must be consistent to avoid conflicting moves.Step 2: Evaluate approaches
Centralized service with synchronous updates ensures strong consistency.Step 3: Analyze other options
Asynchronous replication risks stale data; single server limits scalability; client storage risks cheating and inconsistency.Final Answer:
Option A -> Option AQuick Check:
Strong consistency requires centralized control [OK]
Quick Trick: Strong consistency -> centralized service [OK]
Common Mistakes:
MISTAKES- Choosing eventual consistency for real-time game
- Ignoring scalability by single server
- Trusting client-side state for authoritative data
Trap Explanation:
PITFALL- Candidates often pick scalable but inconsistent approaches, missing real-time consistency requirements.
Interviewer Note:
CONTEXT- Tests distributed system design and consistency trade-offs
