You have an Azure Front Door with a single frontend host Frontend1 and an associated WAF policy Policy1. Policy1 currently redirects requests containing a header value "string1" to https://www.contoso.com/redirect1. You need to add a rule so that requests containing a header value "string2" are redirected to https://www.contoso.com/redirect2. Which three steps should you take? (Choose three.)

To achieve the desired redirection, you need to add a new rule within the existing WAF policy. First, you must "Create a custom rule" because the redirection logic based on a specific header value is not covered by pre-defined managed rules. Next, you will "Add a custom rule to Policy1" as the existing WAF policy is already associated with Frontend1, and you want this new redirection to apply to the same frontend. Finally, you need to "Create an association between the rule/policy and Frontend1" to ensure the newly created custom rule within Policy1 is actively enforced on Frontend1. Creating a new policy or an additional frontend host is unnecessary as the existing setup can be modified. Configuring a managed rule is incorrect because this scenario requires custom logic.
