Free Practice Questions for Zscaler ZTCA Exam

The correct answer is A. In Zero Trust architecture, verification of both user identity and device context should be applied to any person requesting access to an enterprise-controlled application. That includes employees, contractors, partners, and other third parties. Zscaler’s Universal ZTNA guidance states that Zero Trust gives users access to applications based on granular, context-based policies and that the user can be anywhere while the application can be hosted anywhere. This model is not restricted only to remote employees or only to outside parties.

The central principle is that no category of user receives automatic trust simply because of employment status, device ownership, or location. Instead, every access request must be evaluated using current identity and contextual information. That is why Zero Trust architectures verify not just the individual but also conditions such as device posture, location, group, and other policy-relevant attributes. Restricting this verification only to remote staff, unmanaged devices, or external users would recreate the implicit-trust problem that Zero Trust is meant to eliminate. Therefore, the correct architectural answer is that verification should apply to any person connecting to an enterprise-controlled application.

The correct answer is D . Zscaler’s Zero Trust architecture specifically contrasts modern distributed environments with legacy VPN- and firewall-based designs. The reference architecture explains that users are now remote, applications can be hosted in public cloud, private cloud, or data centers, and access must work across any location. In legacy models, organizations respond by extending IP connectivity outward through VPNs, firewalls, and other network-based controls. That expansion increases the attack surface, preserves broad network trust, and drives network sprawl instead of reducing it.

The same guidance states that Zero Trust gives users access to applications without ever placing them on the network or exposing apps to the internet . This is important because legacy architectures extended the organizational perimeter to end users, allowing lateral movement and increasing risk when users and apps became more distributed. Option A describes a symptom of legacy complexity, but option D captures the broader trend that is causing the sprawl in the first place: cloud migration, remote users, and the continued use of VPN and firewall architectures to maintain connectivity. That is the most accurate Zero Trust answer.
