A server administrator is given the hash of an account password that needs to be synchronized across all servers. Which of the following will allow the server administrator to configure the account…

The `/etc/passwd` file stores user account information but does not store the password hash directly; it typically has an 'x' in the password field, indicating the hash is in `/etc/shadow`.

The `passwd` command is used by users or root to change passwords, but it computes and stores the hash from a plaintext input, it does not accept a pre-computed hash.

The `/etc/shadow` file is where Linux systems securely store user password hashes along with other password-related information. Directly editing this file is the method to manually insert or change a password hash, assuming proper permissions and hash format.

The `usermod` command is used to modify user account details, including setting an initial password, but it also takes a plaintext password that it hashes, or refers to the `/etc/shadow` file indirectly, and does not accept a raw hash.
