質問 # 15
An AOS-CX switch has this admin user account configured on it:
netadmin in the operators group.
You have configured these commands on an AOS-CX switch:
tacacs-server host cp.example.com key plaintext &12xl,powmay7855
aaa authentication login ssh group tacacs local
aaa authentication allow-fail-through
A user accesses the switch with SSH and logs in as netadmin with the correct password. When the switch sends a TACACS+ request to the ClearPass server at cp.example.com, the server does not send a response.
Authentication times out.
What happens?
- A. The user is logged in and allowed to enter auditor commands only.
- B. The user is not allowed to log in.
- C. The user is logged in and granted operator access.
- D. The user is logged in and granted administrators access.
正解：C
解説：
Comprehensive Detailed Explanation
The configuration includes the command aaa authentication allow-fail-through, which specifies that if the TACACS+ server fails to respond (e.g., times out), the switch will proceed to the next authentication method in the sequence, which is local. In this scenario:
* The switch first attempts to authenticate the user against the TACACS+ server.
* When the TACACS+ server fails to respond, the switch falls back to local authentication.
* The user netadmin is a local account configured on the switch and belongs to the operators group.
* As a result, the user is successfully authenticated locally and is granted operator level access.

質問 # 16 
The exhibit shows the 802.1X-related settings for Windows domain clients. What should admins change to make the settings follow best security practices?
- A. Clear the check box for using simple certificate selection and select the desired certificate manually.
- B. Select the desired Trusted Root Certificate Authority and select the check box next to "Don't prompt users."
- C. Specify at least two server names under the "Connect to these servers" field.
- D. Under the "Connect to these servers" field, use a wildcard in the server name.
正解：C
解説：
To follow best security practices for 802.1X authentication settings in Windows domain clients:
* Specify at least two server names under "Connect to these servers":
* Admins should explicitly list trusted RADIUS server names (e.g., radius.example.com) to prevent the client from connecting to unauthorized or rogue servers.
* This mitigates man-in-the-middle (MITM) attacks where an attacker attempts to present their own RADIUS server.
* Select the desired Trusted Root Certificate Authority and "Don't prompt users":
* Select the Trusted Root CA that issued the RADIUS server's certificate. This ensures clients validate the correct server certificate during the EAP-TLS/PEAP authentication process.
* Enabling "Don't prompt users" ensures end users are not confused or tricked into accepting certificates from untrusted servers.
* Why the other options are incorrect:
* Option C: Incorrect. Wildcards in server names (e.g., *.example.com) weaken security and allow broader matching, increasing the risk of rogue servers.
* Option D: Incorrect. Clearing "Use simple certificate selection" requires users to select certificates manually, which can lead to errors and usability issues. Simple certificate selection is recommended when properly configured.
Recommended Settings for Best Security Practices:
* Server Validation: Specify the exact RADIUS server names in the "Connect to these servers" field.
* Root CA Validation: Ensure only the correct Trusted Root Certificate Authority is selected.
* User Prompts: Enable "Don't prompt users" to enforce automatic and secure authentication without user intervention.
