Infrastructure Security

Question Image

Refer to the exhibit. A network administrator logs in to the router with TACACS+ username and password credentials, but cannot execute any privileged commands.

Which action resolves this issue?

  • A Configure the username from a local database
  • B Configure TACACS+ synchronization with the Active Directory admin group
  • C Configure an authorized IP address for this user to access this router
  • D Configure full access for the username from TACACS+ server
Explanation

TACACS+ performs authentication and authorization separately. A successful login with a failed authorization response means the account is authenticated but is not authorized for privileged EXEC or command access. Assigning full access (appropriate privilege and command authorization) to the username on the TACACS+ server permits the privileged commands.
