When using SSH keys for CLI authentication for firewall administration, which method is used for authorization?
A . Local
B. LDAP
C. Kerberos
D. Radius

Answer: A

Explanation:

When using SSH keys for CLI authentication for firewall administration, the method used for authorization is local. This is described in the Palo Alto Networks PCNSE Study Guide in Chapter 4: Authentication and Authorization, under the section "CLI Authentication with SSH Keys":

"SSH keys use public key cryptography to authenticate users, but they do not provide a mechanism for authorization. Therefore, when using SSH keys for CLI authentication, authorization is always performed locally on the firewall."
