We can insert multiple documents in bulk using which of the following operations:

Question

Options

• AinitializeUnorderedBulk
• BinitializeUnorderedBulkOp
• CinitializeBulk
• DinitializeBulkOp

• A
  3% (1)
• B
  94% (34)
• D
  3% (1)

Explanation

initializeUnorderedBulkOp() is the correct MongoDB shell method for initializing a bulk write operation that processes documents in any order, allowing multiple inserts (and other write operations) to be batched and executed together. Option A (initializeUnorderedBulk) is wrong because it's missing the Op suffix - this exact suffix is required and is part of the official API name. Options C and D (initializeBulk / initializeBulkOp) are fabricated; MongoDB's bulk API only exposes initializeUnorderedBulkOp() and its counterpart initializeOrderedBulkOp(), so neither prefix-only variant exists.

Memory tip: Think "Un-Op" - Unordered Operation - the full word Op must be present, and you need both the ordering qualifier (Unordered) and the operation suffix (Op) to spell out the real method name.
