Zscaler Updated ZDTA Exam Questions and Answers by everlyn

For a deployment using both ZIA and ZPA, the cleanest authentication model is SAML for both services. A shared SAML IdP gives consistent identity, attributes, and group context for internet/SaaS access and private-application access. Option C (Configure Authentication using SAML on both ZIA and ZPA) is correct because using SAML on both ZIA and ZPA provides unified authentication.

Why the other options are incorrect:

A. Use forms Authentication in ZPA and SAML in ZIA: SAML provides browser-based federation by carrying signed assertions from the identity provider to the service provider.

B. Use forms Authentication in ZIA and SAML in ZPA: SAML provides browser-based federation by carrying signed assertions from the identity provider to the service provider.

D. Use forms Authentication for both ZIA and ZPA: Forms authentication is an application-login method. ZIA and ZPA authentication should be based on the supported identity integration model in the scenario, not generic forms auth.

Client Connector automatically checks for software updates on a recurring schedule so endpoint agents remain current without manual user action. The tested default software-update interval is two hours. Option C (Every 2 hours) is correct because the automatic software-update check occurs every two hours.

Why the other options are incorrect:

A. Every 6 hours: Six hours would delay client software update checks beyond the default cadence. Zscaler Client Connector checks the software update policy every two hours.

B. Every 12 hours: Twelve hours is far too slow for the default software update policy check. The default interval is two hours.

D. Every 24 hours: Twenty-four hours would mean only a daily update-policy check. ZCC checks software update policy much more frequently: every two hours.

Advanced Threat Protection defends users from malicious active content, phishing, exploit behavior, C2 callbacks, and risky web destinations. It works as part of ZIA's inline security stack, often alongside TLS inspection, Cloud Sandbox, DNS security, IPS, and URL categorization. Option A (Cloud App Control) is correct because malicious active content is the security object ATP is designed to detect and block.

Why the other options are incorrect:

B. URL Filtering: URL Filtering controls web destinations by category, URL, risk, and action such as allow, block, caution, or isolate.

C. Advanced Threat Protection: Advanced Threat Protection blocks malicious active content and related threats. The question is asking for the policy feature named by the configured category, which is not ATP here.

D. Mobile Malware Protection: Mobile Malware Protection focuses on mobile-device malware. The tested ZIA feature is broader web/cloud enforcement rather than mobile-only protection.

Alert Rules can come from Zscaler's ThreatLabZ predefined detections or from customer-defined logic. This lets organizations combine vendor threat intelligence with tenant-specific alerting requirements. Option A (ThreatLabZ pre-defined and customer defined) is correct because the two alert-rule types are ThreatLabZ predefined and customer defined.

Why the other options are incorrect:

B. Snort defined and 3rd party defined: A third-party PageRisk feed would be externally sourced reputation; the Zscaler answer is its own multi-data web-page algorithm.

C. ThreatLabZ pre-defined and 3rd party defined: A third-party PageRisk feed would be externally sourced reputation; the Zscaler answer is its own multi-data web-page algorithm.

D. Customer defined and 3rd party defined: A third-party PageRisk feed would be externally sourced reputation; the Zscaler answer is its own multi-data web-page algorithm.
