Network administrators are reporting that switches are taking a very long time to execute commands. Based on the configuration below, what is the most likely cause of the issue?

Explanation
The configuration shows two TACACS+ servers (10.1.1.1 and 10.1.1.2) with fail-through enabled. If the primary TACACS+ server (10.1.1.1) is unreachable, the switch waits for a timeout before trying the secondary server. This delay causes commands to take a very long time to execute, as each authentication attempt has to fail on the primary before moving on.
