Free Practice Questions for Zscaler ZDTA Exam

A primary business risk introduced by legacy firewalls is performance issues. Traditional firewalls are often unable to efficiently handle modern high-volume and encrypted traffic, leading to latency, bottlenecks, and reduced network performance. This negatively impacts user experience and security posture. The study guide points out that legacy firewalls struggle with scalability and speed in today’s cloud-centric environment, making performance a key concern.

Virus scanning in the Zscaler platform is part of its Malware Protection capability, which inspects file content against known virus signatures and behaviors.

Prevent Compromise analyzes device and network telemetry - including security configurations, event logs, and traffic flows - to gauge how well you’re blocking initial intrusion attempts and misconfigurations.

The graph in the Security Alerts section displays the Top 5 Threats by Systems Impacted, highlighting which threats have affected the most endpoints over the selected time period.

When tunnels (GRE/IPSec) are already configured from trusted locations (like branch offices), the recommended 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.

When creating SSL inspection policies, the exception policy for the specific URL category must appear first in the policy list, followed by the more generic "inspect all" policy further down. Zscaler evaluates policies in order, so placing the exception first ensures that traffic matching that category bypasses inspection before the generic policy is applied.

The study guide emphasizes the importance of policy order to ensure correct application of exceptions and general rules.

Zscaler’s IPS engine and Yara‑style content signatures specifically detect and block botnet command‑and‑control traffic, stopping infected hosts from communicating with C2 servers.

Zscaler Bandwidth Control shapes and buffers only the outbound traffic from the user’s device, ensuring smooth egress flow, while inbound and localhost traffic remain unshaped.

The TLS Decryption platform service intercepts and decrypts SSL/TLS sessions, granting Zscaler access to both headers and payloads of encrypted traffic for inspection and policy enforcement.

Zscaler’s short‑lived intermediate CA certificates on the ZIA Service Edges are valid for 14 days and are automatically rotated every 7 days, minimizing the window of exposure even if a private key is compromised.
