What are two default password requirements on Junos devices? (Choose two.)

On Junos devices, one of the default password requirements is that the password must be at least six characters in length. This ensures a minimum level of complexity and security, as shorter passwords are generally easier to guess or crack. Setting a minimum length helps protect the device from unauthorized access by requiring users to create passwords that are more robust and challenging to compromise.

Additionally, another requirement that aligns with best practices for creating secure passwords is that they must use alphanumeric character classes. This means that passwords should include both letters and numbers, which increases complexity and enhances the security of the password. By incorporating different types of characters, it becomes more difficult for attackers to guess the password, as they have to consider a larger set of possible combinations.

In summary, a minimum length of six characters and the use of alphanumeric character classes are fundamental requirements that contribute to the security posture of Junos devices.
