Question 470
Before accepting a Zscaler configuration change, the team discovers: A user can reach a private web application login page through ZPA but a required backend reporting client connection fails on a separate authorized port. What ongoing operational safeguard should the team adopt?
Explanation
Correct Answer
This safeguard mitigates app segment missing database port: Keep exact destination protocols in app-owner runbooks and retest them following application releases. The risk being controlled is: An application segment and port definition can permit one service while excluding another required protocol on the same destination. A safeguard for an unrelated failure would not address it.
Incorrect Answers
A valid existing security association can mask impending credential expiration until a later renegotiation requires current authentication material. “Monitor tunnel credential expiry and include a rotation test before cryptographic material reaches end of validity” would remedy that alternative situation, but it would not correct the present issue: an application segment and port definition can permit one service while excluding another required protocol on the same destination.
“Include private application entitlement checks in staff transfer and identity provisioning workflows” is the supported response when ZPA access is matched against current identity and group conditions; the new group may not satisfy the application's rule. Here the decisive response is “Keep exact destination protocols in app-owner runbooks and retest them following application releases”, so that different intervention does not meet the stated requirement.
Policy evaluation order can cause the generic allow to win before the more specific restrictive rule is considered. “Require negative category tests whenever global allow rules are added or policy fragments are merged” applies to that other condition. The reported evidence is a user can reach a private web application login page through ZPA but a required backend reporting client connection fails on a separate authorized port; this alternative would address the wrong dependency.
