A team wants a metric that reflects whether a policy can serve admission requests. Which label of the rule info metric carries that?

選択肢

1. The rule execution cause label, because a rule that cannot serve admission requests is only ever executed by a background scan and the cause therefore encodes the readiness indirectly.
2. The policy background mode label, whose true value means the same thing.
3. The policy validation mode label, because a policy that is not ready falls back to audit and the mode therefore reveals the readiness without a dedicated label.
4. The status ready label, whose true value means the policy is able to serve admission requests.
