Conditions for SSH Operation on Cisco IOS Switch

DE

To ensure that SSH operates normally on a Cisco IOS switch, there are certain conditions that must be met.

The correct answers are:

D. The switch must be running a k9 (crypto) IOS image. E. The ip domain-name command must be configured on the switch.

Explanation:

A. IP routing must be enabled on the switch: This is not a requirement for SSH to operate normally. IP routing is a feature that enables the switch to route IP packets between different networks.

B. A console password must be configured on the switch: This is also not a requirement for SSH to operate normally. A console password is used to restrict access to the console port of the switch.

C. Telnet must be disabled on the switch: Telnet is an insecure protocol, and it is recommended to disable it in favor of SSH. However, this is not a requirement for SSH to operate normally.

D. The switch must be running a k9 (crypto) IOS image: This is a requirement for SSH to operate normally. The k9 image includes the cryptographic features required for secure communication using SSH.

E. The ip domain-name command must be configured on the switch: This is also a requirement for SSH to operate normally. The ip domain-name command is used to configure the domain name of the switch, which is used to generate the SSH key pair required for secure communication.

In summary, for SSH to operate normally on a Cisco IOS switch, the switch must be running a k9 IOS image, and the ip domain-name command must be configured on the switch.
