Answer: Utilize Amazon ElastiCache for Redis to compute and cache scores for the scoreboard.
The correct answer is B: 'Utilize Amazon ElastiCache for Redis to compute and cache scores for the scoreboard.' Amazon ElastiCache for Redis is well-suited for scenarios requiring real-time leaderboard calculations. It offers in-memory data storage with high performance and low latency, making it ideal for computing and caching the top-10 scores dynamically as players compete. This solution ensures that the scoreboard is updated in near real-time and supports the game's requirement to display scores, pause, and resume with score preservation. Options A and C do not provide the necessary real-time computational capability, and Option D would introduce unnecessary read latency and complexity.
