Authentic Zscaler Certification Exam ZTCA Questions Answers

The correct answer is B. False . Zero Trust architecture does not treat identity and context as a one-time, fixed decision. Zscaler’s architecture guidance shows that access is based on ongoing context , including user identity, device posture, location, and other factors that can change over time. For ZIA, policy assignment evaluates the user, device, location, group, and more to determine which policies apply. For ZPA, user access is matched against current conditions such as location, device posture, user group, department, and time of day .

Zscaler documentation also describes reauthentication intervals and session timeout controls, which further shows that identity and authorization are not treated as permanently settled after one decision. In addition, device posture checks can be repeated over time, and a failed posture check can cause a different policy to be applied.

This is fundamental to Zero Trust: trust is continually evaluated , not granted once and assumed valid for an arbitrary period such as 48 hours. Therefore, the statement is false because identity and access context must be revisited as conditions change.

The correct answer is B. False . In Zero Trust architecture, identifying and validating who is making a request is normally handled through enterprise identity systems , not by a government agency. Zscaler’s authentication architecture explains that authentication credentials and identity responses from an Identity Provider (IdP) are the first step in determining which policies should apply. Those responses can include the user’s identity, groups, and department, which are then used in policy enforcement.

ZPA guidance also shows that SAML and SCIM attributes from the identity provider are used to support application access policy. This means the “who” value is typically proven through the organization’s identity stack, such as an IdP, directory service, or integrated authentication platform, not through an external government authority.

While government-issued identity documents may be part of a hiring or registration process in some organizations, that is not how Zero Trust runtime identity verification is generally performed. In practice, the “who” is established through enterprise-controlled authentication and context systems. Therefore, the statement is false.

The correct answer is B . Zscaler’s Zero Trust architecture is designed to provide secure connectivity over any underlying network infrastructure , while granting access only to authorized requests and based on granular policy. The Universal ZTNA architecture states that users can be anywhere, applications can be hosted in any location, and there are no IP dependencies, while granular, context-based policies control application access . It also explains that Zero Trust gives users access without requiring them to share network context or routing domain with the applications they need.

Option A is directionally true, but it is narrower than the broader Zero Trust benefit being tested. Option C is incorrect because Zero Trust does not rely on placing users onto an internal routed network through a gateway. Option D describes the complexity of legacy IP-based controls, not an advantage of Zero Trust. Zscaler documentation further emphasizes that users connect directly to apps, not the network , minimizing attack surface and eliminating lateral movement. Therefore, the strongest and most complete advantage over legacy controls is network-agnostic connectivity that is limited to authorized and compliant requests .
