Free Practice Questions for Zscaler ZDTA Exam

The Microtunnel (M-Tunnel) in Zscaler is designed to create an end-to-end communication channel to internal applications. This tunnel facilitates secure and direct access from the client device to internal corporate applications without exposing the network or requiring traditional VPN infrastructure. The M-Tunnel is part of ZPA’s mechanism to ensure secure, zero-trust access to private resources.

Zscaler Client Connector’s Tunnel 2.0 uses a packet‑filter based tunnel that encapsulates all IP traffic - both TCP and UDP on any port, plus ICMP - to the Zero Trust Exchange

You need at least two App Connectors per data center to ensure high availability and load distribution, so with four data centers the minimum total is eight.

After the Zscaler Client Connector (ZCC) receives a valid SAML response, Zscaler Internet Access (ZIA) takes over to validate the SAML assertion. Upon successful validation, ZIA issues an authentication token that allows the user to access services securely. This centralized validation ensures authentication integrity and enables seamless policy enforcement across Zscaler services.

The “Blocked Countries” feature in Advanced Threat Protection lets you restrict access to web destinations based on their geographic location, preventing connections to any sites hosted in the specified countries.

Zscaler Client Connector’s Tunnel 2.0 encapsulates user traffic in DTLS (or TLS) tunnels to the Zero Trust Exchange, providing both transport security and protocol flexibility before handing off to Zscaler’s inspection and enforcement engines.

Zscaler Platform Services, such as web filtering, advanced threat protection, DLP, and more, operate on decrypted traffic. This decryption is enabled by TLS Inspection, which intercepts SSL/TLS sessions, decrypts the payloads for inspection, and then re‑encrypts the traffic before forwarding to the destination.

Malware Protection for HTTPS traffic relies on the Zero Trust Exchange’s TLS Inspection to decrypt the SSL/TLS stream, enabling the malware‑detection engines to scan payloads against known threat signatures.
