Zscaler Updated ZDTA Exam Questions and Answers by tamara

Zscaler Zero Trust Automation uses RESTful API architecture. REST aligns with standard HTTP methods such as GET, POST, PUT, and DELETE and is the expected API style for OneAPI and Zscaler automation workflows. Option D (REST) is correct because REST is the API architectural style used.

Why the other options are incorrect:

A. JSON-RPC: JSON-RPC is a remote procedure call style; Zscaler automation APIs are REST-style resources and methods.

B. SOAP: SOAP is an XML-based protocol with envelopes and operations; it is not the REST style used for Zscaler automation.

C. GraphQL: GraphQL lets clients query exactly shaped data through a schema; Zscaler Zero Trust Automation uses REST instead.

The failure is caused by an unstable trusted-network signal, so the trusted definition and associated forwarding decisions must be corrected. Zscaler’s Trusted Network search reference lists default gateway and egress IP among the available criteria. Combining stable campus properties prevents the public DNS-resolver change from intermittently classifying on-campus devices as off-trusted. Zscaler’s Forwarding Profile guidance supports applying different forwarding behavior according to trusted-network status. Option B then makes policy intent explicit: HR and SIP bypass only after the campus match, while the following off-trusted rule forwards those applications for inspection when users roam. PAC fallback or proxy enforcement adds another decision path without repairing detection. Relaxing posture checks does not identify the network and would weaken device controls.

Zscaler DLP separates detection logic from enforcement policy. Dictionaries contain the sensitive-data patterns, keywords, identifiers, regexes, or fingerprinted data that identify protected information. DLP engines use those dictionaries to evaluate content, and DLP rules or policies decide the enforcement action. Option C (DLP dictionaries) is correct because the detection foundation of a DLP engine is the dictionary content it evaluates against traffic or files.

Why the other options are incorrect:

A. DLP Policies: DLP policies are the enforcement layer that selects actions such as block, notify, quarantine, or allow.

B. DLP Rules: DLP rules combine detection conditions and policy logic; they are not the content-pattern library itself.

D. DLP identifiers: DLP identifiers are individual match elements, while the broader engine/dictionary structure does the content detection work.

Data Loss Prevention is the central feature of Zscaler Data Protection. It detects sensitive information using engines, dictionaries, labels, EDM/IDM, and contextual controls, then applies actions such as block, notify, coach, quarantine, or remediate. Option A (Data loss prevention) is correct because DLP is the named core feature for protecting sensitive data.

Why the other options are incorrect:

B. Stopping reconnaissance attacks: Stopping reconnaissance is about hiding attack surface. Data protection addresses exfiltration and accidental data loss.

C. DDoS protection: DDoS protection absorbs or blocks traffic floods. It does not inspect sensitive content leaving through web and cloud channels.

D. Log analysis: Log analysis helps detect and investigate events after collection. DLP use cases prevent the sensitive transfer itself.
