ZDTE Zscaler Digital Transformation Engineer Free Practice Exam Questions (2026 Updated)

In Zscaler, the Endpoint DLP report is specifically designed to give security teams visibility into how end users interact with sensitive data on their endpoints (laptops, desktops, etc.). This report aggregates activity such as copying, saving, printing, uploading, or otherwise handling sensitive content that is detected and classified by Zscaler Endpoint DLP. It focuses on data risk rather than just malware or traffic volumes, so it shows which files, users, and devices are involved in policy matches, along with the context of each event.

Unlike a generic malware or data usage report, the Endpoint DLP report is tightly aligned with DLP policies and data classifications you configure (such as PII, financial data, source code, or custom patterns). This allows you to quickly see which policies are triggering on endpoints, which channels or applications are most frequently involved, and where to fine-tune rules or add additional controls. Because it is endpoint-focused, it covers scenarios even when users are off the corporate network, giving a unified view across inline and endpoint DLP enforcement. For exam purposes, this is why Endpoint DLP report is the correct answer.

===========

Zscaler Internet Access (ZIA) supports regional processing requirements through the concept of subclouds. A subcloud is defined as a subset of ZIA Public Service Edges (and optionally Private Service Edges) that operate as full-featured secure internet gateways inspecting all web traffic. ZIA administrators can create a custom pool of data centers (Public Service Edges) that are constrained to a specific geography and then associate locations or tunnels with that subcloud. This ensures that user traffic forwarded to ZIA is only terminated and inspected within that defined regional pool, helping satisfy data-residency and regulatory mandates

By contrast, Zscaler’s default behavior is to use geo-IP and DNS to send traffic to the nearest available Public Service Edge globally, which may violate regional-processing rules (making option D unsuitable in a compliance-driven scenario) Bypassing ZIA (option A) or deploying local VPNs (option C) would undermine the Zero Trust model and remove ZIA’s inline security controls. Therefore, configuring a subcloud that includes only Public Service Edges in the mandated region is the architecturally correct and exam-aligned method to keep inspection within a specific geography.

===========

The ZDTE study content groups Private Service Edge under Advanced Platform Services, explaining that PSEs host the same Zero Trust Exchange policy and inspection engines, but run as customer-managed service edges inside data centers or large offices. They are designed to give on-premises users a “local on-ramp” to ZIA and ZPA services while still enforcing full zero-trust policy.

The documentation emphasizes that PSEs do not replace App Connectors for ZPA; connectors are still required to establish inside-out application connectivity. Nor do PSEs remove the need for ZTNA policies—those policies remain central and are simply enforced closer to the user. Encryption is also preserved end-to-end; there is no “unencrypted fast path” described in the reference architecture.

Instead, the primary benefit highlighted is performance and user experience: by enforcing ZIA/ZPA policies at a local PSE rather than a distant public service edge, organizations reduce round-trip latency and keep traffic on optimal paths while maintaining identical security and access controls.

A subcloud in Zscaler is defined as a subset of ZIA Public Service Edges (data centers) that you group together and associate with specific locations or traffic. Conceptually, it is a logical “pool” of preferred Public Service Edges. When a user or site is mapped to a given subcloud, their traffic is steered only to that selected subset of Service Edges instead of any available data center in the wider cloud.

The main benefit of this design is control and predictability: you can guarantee that web traffic is forwarded to your preferred ZIA Public Service Edges, which is critical when you must keep egress IPs stable for SaaS allow-lists, regulatory requirements, or local data-residency mandates. Subclouds also help with operational resilience, because you can temporarily exclude problematic data centers from a subcloud without changing overall forwarding methods, ensuring continuity while still using your defined group of Service Edges. They do not increase the number of Service Edges, replace ZIA Public Service Edges, or directly affect IP geolocation precision. Therefore, option C correctly captures the primary benefit expected in the ZDTE/EDU-202 context.

===========

Zscaler positions global peering as a core part of delivering low-latency, high-performance access to SaaS and internet destinations. In Zscaler architecture and Microsoft 365 best-practices material, Zscaler explicitly states that it operates an open peering policy, meaning it is willing to peer with any content or service provider that meets standard technical requirements.

Training content used for ZDTE further emphasizes that Zscaler peers broadly with major ISPs, cloud providers, and internet exchanges to minimize hops and improve user experience. Flashcard material summarizing the architecture notes directly that Zscaler’s peering stance is an “open peering policy,” allowing anyone to request connectivity into the Zero Trust Exchange.

Options suggesting Zscaler refuses new peers, restricts to a small list, or has no defined policy contradict this documented approach and would undermine its ability to optimize traffic paths globally. Because the official guidance clearly describes peering as open and inclusive of any qualified provider, the correct choice is that Zscaler has an open peering policy and will peer with any content or service provider.

Zscaler provides specialized Log Streaming Services to export logs from the Zero Trust Exchange into external SIEM or log-analytics platforms for long-term storage and advanced analysis. For Zscaler Private Access (ZPA), the Log Streaming Service (LSS) forwards user activity, user status, App Connector metrics, and other diagnostic logs to a log receiver, which is typically a SIEM, syslog collector, or similar downstream system. Zscaler documentation notes that customers use LSS specifically to store logs beyond the default cloud retention period and to support external analytics and compliance use cases.

On the ZIA side, Nanolog Streaming Service (NSS) fulfills a similar purpose, streaming web and firewall logs from the Zscaler Nanolog cluster into SIEM solutions. Together, these streaming services give organizations centralized visibility and long-term retention while keeping the Zscaler cloud optimized for inline inspection and near-term reporting.

Role-Based Access Control (RBAC) governs who can view or manage configurations, not how logs are exported. The Zero Trust Exchange query or insights interfaces are used for in-portal searching and visualization, and “Log Recovery Service” is not the Zscaler term used for SIEM integration in ZDTE materials. Therefore, Log Streaming Services is the correct answer because it is the named mechanism for streaming Zscaler logs to external SIEM platforms for long-term storage.

===========

Zscaler’s multi-tier cloud architecture is separated into distinct planes: the control plane, enforcement plane, and logging plane. The control plane is implemented by the Central Authority and is described in Zscaler architecture material as the “brains” of the platform, responsible for policy definition, administration, orchestration, and the admin UI. Crucially, this same layer also exposes the API interfaces that automation tools and scripts use. In architecture slides, the control plane is explicitly associated with “Admin UI” and “API,” showing that all administrative programmability terminates there.

The enforcement plane (Public/Private Service Edges) is focused on inspecting and enforcing policy on user traffic, while the logging plane is dedicated to storing and streaming Nanolog data to SIEM or analytics tools. Neither of these planes provides administrative configuration APIs. Study content for the ZDTE exam reinforces that the API infrastructure enables programmatic access to configure the Zero Trust Exchange and is part of the central management layer, not the traffic or logging tiers.

Therefore, when an administrator makes API calls, they are communicating with the Control Plane.

Zscaler’s Shadow IT and Data Discovery capabilities are delivered primarily through its multimode CASB and data protection services. Shadow IT Discovery automatically identifies unsanctioned cloud applications in use and evaluates them across a large set of risk attributes (for example, security controls, compliance posture, data handling, and business continuity).

Updated Zscaler training and exam content for the Digital Transformation Engineer track describes a significantly expanded cloud app catalog, allowing visibility into up to 100,000 applications and evaluation across approximately 200 risk attributes. This scale is necessary to cover the rapidly growing SaaS ecosystem and to give security teams the granularity needed to distinguish between low-risk and high-risk services.

Earlier public materials referenced smaller catalogs (for example, 8,500 apps with 25 attributes), but the current exam-aligned figures reflect the evolution of Zscaler’s data protection and Shadow IT intelligence. Options A, B, and C therefore underrepresent the scope of Zscaler’s catalog and risk model. In the context of the ZDTE curriculum, the correct pairing is 100K apps and 200 risk attributes, which best matches how Zscaler positions its Shadow IT and Data Discovery capabilities for broad visibility and fine-grained risk analysis.

Zscaler OneAPI is designed as a unified, modern API layer that exposes core objects and workflows from ZIA, ZPA, and Zscaler Client Connector in a consistent way. In the Digital Transformation Engineer and Zero Trust Automation material, common and recommended use cases focus on automating tasks that are frequently repeated, error-prone, or need to scale across large environments.

For ZPA, a typical automation scenario is the creation and lifecycle management of App Connectors and App Connector Groups. These components provide the inside-out connectivity from private applications to the Zscaler cloud. Using OneAPI, administrators can programmatically create, update, and organize App Connector Groups, allowing infrastructure-as-code style deployment and rapid scaling of private access environments.

On the endpoint side, OneAPI also integrates with Zscaler Client Connector and identity-related services to enroll or update device information programmatically. This enables workflows such as onboarding new devices, synchronizing device attributes from external systems, and tying device identity to access policy without manual portal operations.

By contrast, installing “antivirus features” in ZCC or “accessing ZDX Copilot” are not highlighted as core OneAPI automation use cases in the referenced curriculum, which makes option B the correct choice.

===========

Zscaler Private Access (ZPA) uses the Log Streaming Service (LSS) to deliver ZPA logs (such as user activity and connector/authentication logs) to external SIEM and analytics platforms. LSS relies on a ZPA App Connector as the local relay between the ZPA service and the downstream log receiver. If network connectivity between ZPA and the local App Connector is interrupted, log delivery may be temporarily disrupted.

According to Zscaler integration guidance, when connectivity between ZPA and the local App Connectors is restored, LSS can retransmit up to 15 minutes of previously undelivered log data, although this retransmission is not guaranteed in all circumstances. This limited replay window is designed to provide reasonable resilience for short outages without requiring large local storage on the connector.

The 15-minute buffer applies specifically to ZPA log streaming scenarios and is distinct from longer-term log retention in Zscaler’s logging cluster or external SIEM. Options A, C, and D overstate the supported replay duration and do not match Zscaler’s documented behavior. To minimize log gaps beyond this 15-minute window, Zscaler recommends resilient network paths for App Connectors and careful monitoring of connector health so that LSS can operate continuously.

===========

Zscaler design guidance for GRE connectivity emphasizes three key principles: terminate GRE on border (edge) devices, avoid NAT on GRE source addresses, and scale bandwidth by using multiple tunnels. In Zscaler documentation and engineering training, each GRE tunnel is typically sized for up to about 1 Gbps of throughput. For a 2 Gbps requirement, customers are advised to deploy at least two primary GRE tunnels, with two additional backup tunnels for redundancy and failover.

These tunnels should terminate on border routers that own public IP addresses, ensuring optimal routing and simplifying troubleshooting. Zscaler specifically recommends that the public source IPs used for GRE must not be translated by NAT, because the Zscaler cloud must see the original, registered public IP to associate tunnels with the correct organization and enforce policy. Enabling NAT on GRE traffic can break tunnel establishment and lead to asymmetric or unpredictable routing.

Using internal routers introduces extra hops and complexity and often requires NAT or policy-based routing, which goes against recommended best practices. Similarly, any architecture with NAT enabled on GRE traffic conflicts with Zscaler’s published requirements. Therefore, the ideal and recommended design for 2 Gbps via GRE is two primary and two backup GRE tunnels from border routers with NAT disabled.

The Domain Joined posture element in ZPA evaluates whether a device belongs to a specific Active Directory domain. ZPA performs this evaluation using the device’s local posture signals, either through the Zscaler Client Connector posture engine or through the browser-based posture evaluation framework used in ZPA Browser Access. When a user connects via Browser Access, ZPA can still determine domain membership by inspecting the allowed browser posture attributes provided by the endpoint, enabling device-based Zero Trust controls without requiring a full Client Connector installation.

Linux endpoints do not support domain-joined posture verification, making option A incorrect. Domain join validation is performed at the device level, not through the Identity Provider, because IdPs validate users, not device domain status, eliminating option D. ZPA’s posture configuration allows you to define multiple domains within a single posture profile, so creating a second posture profile is unnecessary, making option C incorrect.

Therefore, the correct statement is that ZPA Browser Access can determine whether the device is joined to the specified domain, which aligns with the expected behavior of the domain-joined posture element.

In Zscaler 3rd-Party App Governance documentation, the App Inventory is where administrators view and manage all discovered third-party apps, add-ons, and extensions. The “Classifying Apps” help article defines the available states: Unclassified, Sanctioned, Reviewing, and Unsanctioned. Crucially, it notes that Unclassified is the default state for any new application before an administrator evaluates it.

“Sanctioned” is used once the organization has explicitly approved an app for use; “Unsanctioned” is used when an app is not allowed; and “Reviewing” indicates it is under investigation. Those labels are the result of governance decisions applied after discovery.

ZDTE study materials on SaaS and app governance mirror this behavior: newly discovered apps enter the inventory without an explicit decision, allowing security teams to triage risk, review permissions, and only then mark them as sanctioned or unsanctioned. Because the default state for a new entry is explicitly documented as Unclassified, the correct answer is D. Unclassified.

In a typical enterprise authentication setup, Zscaler functions as the Service Provider (SP) within the SAML authentication framework. This aligns with Zscaler’s architectural principle that identity verification is delegated to an external authoritative Identity Provider (IdP) such as Azure AD, Okta, Ping, or ADFS. Zscaler does not authenticate user credentials directly. Instead, it relies on the IdP to validate the user and then deliver a signed SAML assertion back to Zscaler.

When a user attempts to access the Zscaler service, the authentication request is redirected to the enterprise IdP. The IdP performs credential verification and returns a SAML assertion containing the authenticated user identity and associated attributes. Zscaler, acting as the SP, consumes and validates this assertion, then maps the identity to its internal user records or SCIM-synchronized directory objects. This identity becomes the basis for all ZIA/ZPA policy evaluation, including URL filtering, CASB controls, DLP policies, firewall rules, and access-control enforcement.

Since Zscaler depends on the IdP for primary identity verification and only consumes assertions, Zscaler’s role is clearly defined as the Service Provider in a standard authentication configuration.
