1. What is Hash slot ? Junior A. horizontally partitioning the keyspace across multiple primary nodes so each holds only a subset of the data B. one of 16384 buckets to which every key is mapped, determining which node in a sharded deployment owns that key C. a substring enclosed in braces within a key that forces related keys into the same bucket so multi-key operations work D. migrating ownership of buckets between nodes to rebalance load or accommodate added or removed members
2. Which term means: "one of 16384 buckets to which every key is mapped, determining which node in a sharded deployment owns that key"? Junior A. Sharding B. Hash slot C. MOVED redirection D. Resharding
