Pass the Zscaler Zero Trust Associate ZTCA Questions and answers with ExamsMirror

The correct answer is B . Traditional networks have historically relied on implicit trust because the foundational model of TCP/IP networking is built to enable connectivity , not to establish trust or least-privileged access. Once a user or device is on the network, routing and addressing make it possible to reach other resources unless additional controls are layered on top. This is exactly the legacy pattern that Zero Trust seeks to replace.

Zscaler’s Universal ZTNA guidance explains that legacy approaches connected users to applications by placing them in the same network context or routing domain , whereas Zero Trust decouples the user from the network and allows access only to approved applications. The architecture specifically states that users should access applications without sharing network context with them and that granular, context-based policy should control access instead of implicit network trust.

So the underlying reason is architectural: traditional networking protocols were optimized for reachability and communication, not identity-based trust decisions. That is why implicit trust became common, and why Zero Trust is such a significant shift away from the old model.

The correct answer is A. Over any network with per-access control. In Zero Trust architecture, access is provided to the specific application , not to the underlying network. This is a foundational design principle in Zscaler’s Universal Zero Trust Network Access (ZTNA) guidance. Users can connect from any location and over any network , while policy is enforced per user, per device, per application, and per session . This differs from legacy approaches that first place the user onto the network and then rely on network segmentation or firewall rules to limit access.

Option B is incorrect because establishing a full network-layer connection is characteristic of legacy VPN-based access, which extends network trust and increases lateral movement risk. Option C is also incorrect because Zero Trust is not defined by building a virtual appliance stack in front of applications. Option D includes TLS, which is used in Zscaler architectures, but the key Zero Trust concept being tested is not merely encrypted transport; it is brokered, granular, per-access connectivity without exposing the application to broad network reachability. Therefore, the most accurate answer is A .
