ZTCA Exam Dumps : Zscaler Zero Trust Cyber Associate

The correct answer is C . Zscaler’s reference architectures consistently describe the Zero Trust Exchange as a globally distributed inline cloud platform operating across more than 150 data centers worldwide . The Traffic Forwarding in ZIA reference architecture states that Zscaler has deployed ZIA Service Edge devices in 150+ data centers around the world , allowing users to connect to the nearest service edge for policy enforcement, TLS/SSL inspection, firewalling, and other security services. This design removes the need for centralized backhauling and supports consistent security regardless of user location.

The option mentioning “limited core sites” is incorrect because the Zscaler model is specifically designed to avoid relying on a small number of centralized inspection points. The option about “few high-traffic regions” is also incorrect for the same reason. In addition, Zscaler architecture supports private service edge deployment models for organizations that require local processing in private environments, extending the Zero Trust Exchange model beyond public cloud service edges. Therefore, the only accurate architecture-aligned answer is that Zscaler provides scalable inspection at 150+ public locations and in private locations where needed .

In Zero Trust architecture, policy enforcement is conditional and context-based , not limited to a simple binary allow-or-block model. Zscaler’s reference architectures explain that policy is evaluated using the full user context, including identity, device posture, location, group membership, and other conditions. Access decisions are therefore based on whether specific policy conditions are true, rather than only on static network attributes such as source IP address. For example, the same authenticated user may be allowed access from a managed device at headquarters but denied from an airport, even with the same credentials.

Zscaler documentation also shows that Zero Trust policy can go beyond simple pass or deny outcomes by applying additional controls . In DNS Security and Control, requests can be allowed, blocked, or modified. In ZIA policy development, Cloud App controls allow more granular outcomes than standard allow/block, such as restricting specific actions, applying quotas, or controlling what a user can do inside an application. This reflects the Zero Trust principle that enforcement is adaptive, granular, and tied to business and security context rather than network location alone.

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.
