Pass the Zscaler Digital Transformation Administrator ZDTA Questions and answers with ValidTests

In API architecture, an Endpoint is defined as a URL or URI that provides access to a specific resource or service within the API. It acts as a point of interaction where clients send requests and receive responses. This is a standard definition across API implementations, including Zscaler's API framework, where each endpoint represents a distinct function or data resource accessible via the API.

Option A refers to physical devices, which are not considered endpoints in API terms. Option C describes network infrastructure components but not API endpoints. Option D describes an API gateway, which manages API traffic but is not itself an endpoint.

This explanation is consistent with the Zscaler Digital Transformation study guide’s section on Integration and APIs, which clarifies that API endpoints are URLs pointing to specific resources or services within the API framework.

ZscalerAdvanced FirewallsupportsDNS Tunnel and DNS Application Control, capabilities that are not available in the Standard Firewall. This enhances detection and control of DNS-based threats and allows granular enforcement over DNS queries and responses to prevent data exfiltration and command and control activities.

Secure Socket Tunneling Protocol (SSTP)is not supported as a tunnel type by Zscaler. Zscaler supports GRE, HTTP Connect tunnels, and its own proprietary Microtunnels for traffic forwarding and secure connectivity, but SSTP is not among the supported tunnel protocols.

When SSL Inspection is enabled and a user accesses a private application through Zscaler, the user will see aZscaler generated MITM (Man-In-The-Middle) Certificateon their browser session. Zscaler intercepts and decrypts SSL/TLS traffic at the Service Edge and then re-encrypts it before forwarding it to the client, presenting its own certificate to maintain the security of the connection while enabling inspection.

This allows Zscaler to inspect encrypted traffic for threats and policy enforcement transparently without exposing the original server’s certificate. The study guide clarifies this mechanism under SSL Inspection details.

Tenant Restrictionis the ZIA feature that enforces access control policies to prevent access to certain SaaS applications from unmanaged or non-compliant devices. This ensures that only authorized and managed devices can access sensitive corporate SaaS resources, enhancing security posture.

The study guide highlights Tenant Restriction as an essential control for enforcing device compliance in SaaS access policies.

The Cloud Firewall includesDeep Packet Inspection (DPI)capabilities that detect protocol evasion techniques where applications try to communicate over non-standard ports to bypass firewall controls. Once detected, the traffic is sent to the appropriate inspection engines for further handling and mitigation. This ensures that evasive traffic does not bypass security controls.

When theZscaler Office 365 One Click Ruleis enabled,Office 365 traffic is exempted from SSL inspection and other web policiesto optimize performance and user experience. This rule simplifies policy configuration by automatically identifying and excluding Office 365 cloud traffic from inspection, reducing latency and avoiding potential conflicts with Office 365 services.

The study guide clarifies that this rule helps balance security with seamless cloud application usage.

Zscaler uses a proprietary technology calledZscaler PageRiskto calculate risk attributes dynamically for websites. PageRisk assesses the risk level of a website based on a variety of dynamic factors, including the site's content, reputation, and behavior, helping to identify potentially harmful or suspicious sites in real time.

This dynamic risk scoring allows Zscaler to enforce security policies more effectively, blocking or allowing access based on calculated risk rather than static lists alone. The study guide specifies that PageRisk is integral to the platform's adaptive security posture and URL filtering capabilities .

TheForwarding Profilein Zscaler defines thefallback methods and behavior when a DTLS tunnel cannot be established. This profile governs how traffic should be forwarded if the preferred DTLS (Datagram Transport Layer Security) tunnel fails, ensuring continuity by falling back to alternative methods such as TLS or other configured options. It is critical to maintaining secure and resilient connectivity paths for traffic forwarding.

The study guide clarifies that this forwarding profile specifically addresses DTLS fallback behavior to maintain session reliability.

The preferred method for authentication to access Zscaler's oneAPI isOpenID Connect (OIDC). OIDC is an identity layer on top of the OAuth 2.0 protocol and provides a modern, secure, and scalable way to authenticate users and services interacting with the API.

The study guide notes that OIDC supports flexible and secure authentication, making it the recommended choice for API access management within Zscaler’s platform.
