HashiCorp Certified: Vault Associate (002) — Question 1

How many Shamir’s key shares are required to unseal a Vault instance?

Answer options

• A. All key shares
• B. A quorum of key shares
• C. One or more keys
• D. The threshold number of key shares

Correct answer: D

Explanation

The correct answer is D, as Shamir's Secret Sharing requires a specific threshold number of key shares to successfully reconstruct the secret. Options A and C are incorrect because they do not specify the necessary threshold, while option B could imply a variable number that may not meet the requirement.
