Exam CFR-310 topic 1 question 99 discussion

B. Default credentials Explanation: Many switches come with default login credentials (e.g., "admin" and "password"), which can be easily exploited if not changed, making it a common vulnerability. C. Default protocols Explanation: Some switches may have insecure protocols enabled by default (e.g., Telnet instead of SSH), which can expose the device to attacks if not properly configured. Incorrect Responses: A. Default port state: While port configuration is important, this is less commonly a direct vulnerability compared to default credentials and protocols. D. Default encryption: Switches typically do not come with encryption settings enabled by default, so this is less of a vulnerability focus. E. Default IP address: This can be a concern, but it’s not as critical as default credentials or insecure protocols.
