What is the valid shard range for an object DN?
The correct answer is D. 1-32. Option D (1-32) is correct because object DNs (Distinguished Names) use a sharding scheme that spans exactly 32 shards, numbered starting from 1, giving a valid range of 1 through 32.

Explanation
Option D (1-32) is correct because object DNs (Distinguished Names) use a sharding scheme that spans exactly 32 shards, numbered starting from 1, giving a valid range of 1 through 32. This range reflects the system's design for distributing objects across shards for load balancing and scalability.
Why the distractors are wrong:
- A (1-64): Doubles the actual maximum; 64 shards would over-provision beyond the defined architecture.
- B (1-16): Halves the actual maximum; while it starts correctly at 1, it underrepresents the full shard space.
- C (0-15): Wrong on both ends - shards are 1-indexed (not 0-indexed), and 15 is well below the actual upper bound of 32.
Memory tip: Think "1 to 32 - shards start at 1 (never zero, they're not array indices) and max at 32 (a power of 2 that fits neatly in 5 bits)." The key traps are C's zero-based thinking and A's tendency to double the correct answer - anchor on 32 as the ceiling.
