A device connects to the Zero Trust Exchange with missing antivirus telemetry and an unverified...

Answer B is correct. Missing antivirus telemetry and an unverified client certificate mean the device does not satisfy the required posture profile. Under the stated leading-practice design, the session should not receive ordinary application access. A policy can instead direct the user to an isolated browser experience, limiting interaction and preventing sensitive data from reaching the endpoint until the posture requirements are met. ZPA Access Policies can use posture profiles as criteria, while Isolation Policy provides controlled access to eligible private web applications. Corporate Wi-Fi is only network context and must not override failed device verification. The identity provider establishes user identity, but it does not resolve missing endpoint security evidence. Administrators should also log the failed posture conditions for remediation and investigation. See Zscaler’s Isolation Policy overview and Access Policy configuration.
