You have just configured and enabled the Cisco IOS Firewall feature set from a remote location using the Cisco Router and Security Device Manager (SDM) Firewall wizard. You later want to double-check your configuration using Cisco SDM. However, you find that you can no longer connect to the Cisco IOS Firewall using Cisco SDM.
What is the probable cause of this failure?
A.
You must additionally specify the Cisco SDM management port number to gain access when the configuration has been applied.
B.
You have not generated an RSA key pair between the host and device to allow secure access via Cisco SDM.
C.
You have been locked out via access lists that have been applied to the router as a result of your Cisco SDM configuration.
D.
You must specify the host IP address of Cisco SDM in the Configuration panel for allowed management connections.
