A worked example

Shown solved, with the whole explanation open: this is what every question here carries.

5-3Security OperationsModerate

A policy caps passwords at twenty characters, and a user's long passphrase is rejected. What should the policy allow?

At least sixty-four charactersCorrect · your answerCorrect. A 64-character minimum ceiling makes room for passphrases.
Exactly twelve charactersA fixed exact length destroys both usability and strength.
Twenty characters, digits onlyRestricting characters weakens rather than strengthens.
Whatever the database column fitsSchema convenience is not a security rationale.

Correct.

Concept

Length is where password strength actually lives, so a policy's ceiling matters as much as its floor: users choosing long passphrases must not be punished for it.

Why A

Maximum password length should be at least 64 characters to allow passphrases, per the guidance aligned with NIST SP 800-63B.
