Which of the following is a valid password for the Oracle Analytics Cloud administrator?

In Oracle Analytics Cloud, passwords typically need to adhere to specific complexity requirements to ensure security. A strong password often includes a combination of uppercase letters, lowercase letters, numbers, and special characters.

The option chosen, "my-(password11#)", meets these criteria effectively. It contains lowercase letters, numbers, and special characters (the hyphen and the hashtag), creating a sufficient level of complexity.

To elaborate, the inclusion of both letters and numbers, alongside special characters, ensures that the password is resistant to brute-force attacks. Moreover, the use of a common word patterns alongside complexity features aligns well with security best practices.

In contrast, the other options either lack the necessary complexity or contain components that may not be permitted based on usual password policies. For example, some might not allow certain special characters or require a minimum number of numeric digits. Each password policy can vary, but based on the complexity and structural requirements, option C is the strongest and thus considered a valid password for the Oracle Analytics Cloud administrator.
