ZDTA Zscaler Digital Transformation Administrator Free Practice Exam Questions (2025 Updated)

Z-Tunnel 2.0 upgrades over 1.0 by carrying all ports and protocols through the Cloud Firewall for inspection - rather than being limited to just HTTP/HTTPS - ensuring full visibility and control.

Administrators can build custom dictionaries by defining the exact keywords, phrases, or regex patterns that reflect their organization’s sensitive data. Zscaler then uses these dictionaries in its data‑in‑motion policies to accurately identify and block or protect matching content.

Zscaler Client Connector automatically checks for software updates every 2 hours by default.

SCIM (System for Cross‑domain Identity Management) is the open standard API designed for automated provisioning and ongoing synchronization of users’ attributes, such as group and department, between identity providers and service platforms.

The feature that allows Zscaler to apply URL filtering even when a Cloud App control policy explicitly permits a transaction is called Allow Cascading. This feature ensures that even if a cloud application is permitted by the Cloud App control policy, the URL filtering policy can still be enforced. This is useful in cases where granular URL control is needed on top of cloud app permissions, providing layered security controls.

The study guide clearly explains that Allow Cascading enables URL filtering policies to cascade or take precedence and thus still inspect and potentially block URLs even if the cloud app is allowed by policy. This allows administrators to fine-tune access and ensure additional inspection layers on web traffic .

To avoid prompting users with a cloud selection menu in the Zscaler Client Connector (ZCC), administrators should customize the MSI installation package with the CLOUDNAME parameter. This setting ensures the ZCC automatically connects to the correct ZIA cloud instance without user intervention. The CLOUDNAME corresponds to the designated cloud name for the organization’s ZIA tenant, effectively bypassing the prompt. This is outlined under Zscaler's deployment and configuration instructions for ZCC.

Imported MIP labels are applied as matching criteria within a custom DLP Policy, letting ZIA inspect data in motion and enforce actions (block, quarantine, notify) based on the sensitivity label assigned by Microsoft Information Protection.

The preferred method for authentication to access Zscaler's oneAPI is OpenID Connect (OIDC). OIDC is an identity layer on top of the OAuth 2.0 protocol and provides a modern, secure, and scalable way to authenticate users and services interacting with the API.

The study guide notes that OIDC supports flexible and secure authentication, making it the recommended choice for API access management within Zscaler’s platform.

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.

Valid criteria for Access Policy Rules in ZPA include Group Membership, ZIA Risk Score, Domain Joined, and Certificate Trust. These attributes allow granular policy decisions based on user identity, device posture, and risk context.

Options including password are invalid as passwords are not used as policy criteria; similarly, SNI and Branch Connector Group are more relevant to other controls. The study guide lists these user and device attributes explicitly as policy criteria within ZPA access policies.

Zero Trust is achieved by granting users application‑level access without ever placing them on the same network as the destination, ensuring users can reach only the specific app and never the underlying network.

Data Protection provides comprehensive Data Loss Prevention (DLP) capabilities, inspecting content in motion to identify, block, or encrypt sensitive information based on policy.

Zscaler Advanced Firewall supports DNS Tunnel and DNS Application Control, capabilities that are not available in the Standard Firewall. This enhances detection and control of DNS-based threats and allows granular enforcement over DNS queries and responses to prevent data exfiltration and command and control activities.

Downloaders are a specific type of malware whose primary purpose is to download and install other malicious software onto a victim's machine. Unlike standalone threats, downloaders typically establish initial access and then retrieve payloads like ransomware, trojans, or spyware from a command and control server. Their role in the malware chain is fundamental for multi-stage attacks.

The on-premises VM in the Enterprise Data Management (EDM) process primarily locally analyzes cloud transactions for potential Personally Identifiable Information (PII) exfiltration. This allows organizations to detect and prevent sensitive data leaving their environment by inspecting cloud interactions close to their premises.

The study guide highlights that the VM acts as a local control point in the EDM workflow, ensuring sensitive data protection during cloud transactions.
