Which of the following is true of this scenario?
A) This authentication method is more secure than using certificates or Kerberos.

The use of a pre-shared key implies that all clients share the same key (password) to authenticate with the VPN server, making option B correct. Pre-shared keys are simpler to implement than certificates or Kerberos but are considered less secure because the key must be shared and kept secret among all users, creating a single point of failure.
