Free Practice Questions for Zscaler ZDTA Exam

The forwarding mechanism calledZTunnel with Local Proxycreates a loopback address on the machine to forward traffic to the Zscaler cloud. This local proxy intercepts client traffic on the loopback interface and securely forwards it through the Zscaler cloud, providing flexibility and control over traffic forwarding.

Yes, URL Filtering can make use of Cloud Browser Isolation. Specifically,“Isolate”is an available action in URL Filtering policies that enables users to access potentially risky or untrusted websites in an isolated environment, preventing any malicious content from reaching the user’s device.

The study guide explains that integrating Cloud Browser Isolation into URL Filtering enhances security by isolating risky browsing activities directly from policy enforcement points.

TLS Inspection in Zscaler Internet Access secures public internet browsing bycreating intermediate certificates for each client connection. This Man-In-The-Middle approach enables Zscaler to decrypt and inspect encrypted traffic for threats and policy compliance while still maintaining secure connections with the client. The intermediate certificate acts as a trusted entity between the client and the real server during inspection.

Zscaler Identity Threat Detection and Response gathers information about Active Directory (AD) domains primarily byrunning LDAP queries. LDAP queries allow the system to retrieve user and domain information directly and accurately from the AD infrastructure, enabling detection and analysis of identity threats and suspicious activities.

The study guide highlights the use of LDAP queries as a reliable and standard method for accessing AD domain data in this security context.

When tunnels (GRE/IPSec) are already configured from trusted locations (like branch offices), therecommended setting is “Tunnel v2.0” for on-trusted networks and “None” for off-trusted. This ensures that while on a corporate network, the Zscaler Client Connector uses the pre-established tunnels, but falls back to direct or other secure methods (like VPN or ZCC tunnel) when off-trusted. This aligns with Zscaler's best practices for hybrid deployment.

The recommended minimum number of App connectors to ensure resiliency in Zscaler Private Access is2. Having at least two App connectors provides redundancy, so if one connector fails or is unavailable, the other can continue to provide access without interruption. This recommendation is critical to maintaining high availability and fault tolerance for internal application access.

The study guide specifies this minimum to ensure continuity and reliability of application access through ZPA.

ThePAC file used in the Application Profileis the mechanism that identifies the ZIA Service Edge node that the Zscaler Client Connector should connect to. The PAC (Proxy Auto-Configuration) file contains rules that direct client traffic to the appropriate service edge based on IP ranges, location, or other criteria.

The study guide explains that the Application Profile’s PAC file plays a key role in routing client connections to the nearest or optimal ZIA Service Edge node to ensure efficient traffic forwarding and policy enforcement.

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.
