Zscaler Updated ZTCA Exam Questions and Answers by isla-mae

The correct answer is A . In Zero Trust architecture, enforcement is not limited to a simple allow-or-block outcome. Zscaler’s architecture model supports conditional access controls that let the user proceed while reducing exposure to risk. This is why controls such as isolation are important. Zscaler’s TLS/SSL inspection reference architecture lists browser isolation among the protections enabled by traffic inspection, allowing access to proceed while isolating risky web activity from the endpoint. That matches the idea of allowing access without directly exposing the initiator to the destination’s full risk.

The “steer” concept also fits Zero Trust control logic because traffic can be directed through the most appropriate enforcement path or protective service edge as part of policy execution. By contrast, physical quarantine is a coarse legacy-style response, time-based access does not directly reduce destination risk, and block would deny access entirely rather than allow it safely. In Zero Trust, the better outcome is to preserve business access while applying the right protective control. Therefore, the best answer is Conditionally allow with Isolate and, if needed, Steer .

The correct answer is A . Historically, before modern Zero Trust models were adopted, the normal way to connect a user to an application or service was to place both within a shared network context . This did not always require the exact same subnet, but it did require some level of common routable network connectivity. Legacy architectures assumed that once the user was on the trusted network, or extended into it through technologies such as VPN, they could reach the destination across that network.

Zero Trust architecture changes this assumption. Zscaler’s architectural guidance emphasizes that users should gain access to applications without sharing network context or routing domain with those applications. That is one of the most important distinctions between legacy network-centric security and Zero Trust. The user no longer needs broad network reachability just to get to a specific service. Option B is too narrow because shared access historically did not always mean the same subnet. Options C and D are clearly incorrect. Therefore, the best answer is that initiators and destinations historically shared a network , because legacy connectivity depended on routed network access rather than identity-based, per-application brokerage.

The correct answer is C . In Zscaler’s Zero Trust architecture, the recommended goal is to inspect as much traffic as possible , especially encrypted traffic, because inspection enables key protections such as malware detection, sandboxing, intrusion prevention system (IPS), browser isolation, Data Loss Prevention (DLP), cloud app controls, tenancy restrictions, and file type controls. The TLS/SSL inspection reference architecture explicitly states that organizations should strive for 100% of traffic to be inspected and that Zscaler strongly recommends this as the starting point.

At the same time, the same guidance also confirms that exceptions can exist. It says bypasses may be required for regulatory, vendor, or contractual reasons, and that bypasses should be used only in extreme circumstances . Examples include certificate-pinned applications, some Microsoft 365 flows, and certain regulated destinations. That means the platform should be able to inspect any application or destination , but the enterprise decides where inspection is ultimately enforced. Therefore, the best answer is not “always inspect with no exceptions,” but rather that full inspection is strongly recommended while allowing enterprise-controlled exceptions when justified.
