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 .

The correct answer is A . Zscaler’s Zero Trust architecture explicitly states that applications should be inaccessible unless the user is authorized and that the attack surface should remain invisible even to authorized users until policy allows access. The ZPA segmentation guidance says that decoupling the user from network-based access makes applications invisible unless the user is authorized, and the Universal ZTNA guide similarly states that applications should be inaccessible unless the user is authorized.

This means internal applications should not be exposed by default through open inbound listeners or broad network reachability. The Zero Trust model is to keep applications effectively dark to unauthorized initiators and make them available only through the policy-brokered access path. That is more secure than allowing direct access for on-site users, managed devices, or VPN-connected users, because those approaches reintroduce implicit network trust.

Therefore, the correct implementation is to avoid direct exposure of internal applications and allow access only for authorized users through the Zero Trust access model . That aligns directly with ZPA’s goal of no broad network access and no lateral movement.

The correct answer is A. IPSec and GRE. In the Zscaler Internet Access (ZIA) traffic forwarding architecture, branch offices and sites can send traffic to the Zero Trust Exchange through several forwarding methods. The reference architecture explicitly identifies GRE tunnels and IPsec tunnels as supported methods for forwarding traffic from branch routers, SD-WAN devices, and similar site infrastructure to the nearest ZIA Service Edge.

This is different from Client Connector , which is typically used for individual endpoints such as laptops and mobile devices. For fixed locations, edge-based forwarding protocols are preferred because they allow the site’s egress traffic to be securely transported to Zscaler without requiring the endpoint client on every device. The other options are incorrect because Single Sign-On is an identity function, not a traffic forwarding protocol; Security Appliance and Router are device categories, not protocols; and IKEv2 is associated with IPsec negotiation rather than being presented here as the pair of branch forwarding methods in the ZIA architecture. Therefore, the two protocols specifically called out as alternative forwarding methods to Client Connector are IPSec and GRE .
