Test Switch Security and Authentication | Cisco Exam 200-125

D

The correct answer is B. Switch>ssh -v 1 -l admin 10.1.1.1

Secure Shell (SSH) is a protocol that allows for secure communication over an insecure network. It provides encryption and authentication to protect data transmitted over the network. To test whether a switch supports secure connections and strong authentication, we need to use the SSH command with the verbose (v) option and specify the version of SSH to use.

Option A uses the SSH command on a router and specifies SSH version 1 with the verbose option and a username of "admin" to connect to the IP address 10.1.1.1. While this command tests the SSH connection, it does not test whether the switch supports secure connections and strong authentication.

Option B is the correct answer, as it uses the SSH command on a switch and specifies SSH version 1 with the verbose option and a username of "admin" to connect to the IP address 10.1.1.1. This command tests whether the switch supports secure connections and strong authentication.

Option C uses the SSH command on a switch and specifies a username of "admin" to connect to the IP address 10.1.1.1. This command does not test whether the switch supports secure connections and strong authentication.

Option D uses the SSH command on a router and specifies SSH version 2 with the verbose option and a username of "admin" to connect to the IP address 10.1.1.1. While this command tests the SSH connection, it does not test whether the switch supports secure connections and strong authentication.

In summary, option B is the correct answer as it tests whether the switch supports secure connections and strong authentication using the SSH command with the verbose option and specifying the version of SSH to use.
