ZDTA Zscaler Digital Transformation Administrator Questions and Answers

A Watering Hole Attack targets users by compromising a website or service that is commonly visited by the intended victims. The attacker injects malicious content such as malicious JavaScript or malware into the website, so when the user visits the site, their system gets infected. This attack relies on the trust users have in popular or legitimate websites and exploits it by turning those sites into infection vectors.

Pre-existing Compromise refers to attacks where the target environment is already compromised before the attack is recognized, but it does not specifically describe malicious content injected intopopular websites. Phishing Attack involves deceiving users to click malicious links or reveal credentials, not compromising websites directly. Exploit Kits are automated tools that scan for vulnerabilities and deliver exploits but are not characterized by the use of commonly used websites hosting malicious scripts.

The study guide clearly explains Watering Hole Attacks as a method where attackers infect trusted websites frequented by target users to deliver malicious payloads.

The forwarding mechanism calledZTunnel with Local Proxycreates a loopback address on the machine to forward traffic to the Zscaler cloud. This local proxy intercepts client traffic on the loopback interface and securely forwards it through the Zscaler cloud, providing flexibility and control over traffic forwarding.

In API architecture, an Endpoint is defined as a URL or URI that provides access to a specific resource or service within the API. It acts as a point of interaction where clients send requests and receive responses. This is a standard definition across API implementations, including Zscaler's API framework, where each endpoint represents a distinct function or data resource accessible via the API.

Option A refers to physical devices, which are not considered endpoints in API terms. Option C describes network infrastructure components but not API endpoints. Option D describes an API gateway, which manages API traffic but is not itself an endpoint.

This explanation is consistent with the Zscaler Digital Transformation study guide’s section on Integration and APIs, which clarifies that API endpoints are URLs pointing to specific resources or services within the API framework.

Certificate pinning prevents SSL interception by validating a server’s certificate against known values. When ZIA performs SSL inspection, it substitutes the certificate with one signed by Zscaler’s CA. This causes the handshake to fail for pinned applications. To troubleshoot, an administrator shouldreview SSL logs to identify handshake failures, which indicate certificate pinning issues. Logs will show the TLS negotiation details, including any disruptions.

Inline Data Protection is the process of inspecting data as it transits the network in real time, enforcing policies that prevent sensitive data from being leaked or transmitted improperly. Blocking the attachment of a sensitive document in webmail represents inline data protection because it intercepts and controls data transmission at the network level, stopping sensitive content before it leaves the organization.

Preventing copying to a USB drive is endpoint control and does not happen inline in network traffic. Preventing sharing in OneDrive is cloud access security broker (CASB) activity, often done through API integrations, not inline network control. Analyzing M365 tenant security is an audit or advisory activity, not real-time inline protection.

Therefore, the correct example of inline data protection in Zscaler's cloud security services is blocking the attachment of a sensitive document in webmail.

The Zscaler Client Connector provides the authentication token to the Zscaler Client Connector Portal toenable the portal to register the user’s device and pass the registration to Zscaler Internet Access. This registration process is crucial for device posture assessment and policy enforcement, ensuring that only registered and compliant devices receive appropriate access.

DLP Rulesuse Boolean logic to define complex conditions and combinations for detecting sensitive data. This allows the creation of granular policies that can combine multiple identifiers and dictionaries with AND, OR, and NOT operators to accurately match sensitive content.

Browser Isolationenables secure access to potentially malicious or untrusted websites by rendering web pages in a remote containerized environment. This isolates any harmful content away from the user’s device, ensuring safe browsing without compromising endpoint security. This approach is especially effective for unknown or risky URLs where traditional content filtering might be insufficient.

AZIA Sublocationis defined as a subsection of a corporate Location that is used to separate different types of traffic, such as traffic from employees versus guest traffic. This segmentation allows granular application of policies and better control over different user groups within the same corporate location. Sublocations help in organizing and managing traffic flows for better policy enforcement and reporting.

Tenant Restrictionis the ZIA feature that enforces access control policies to prevent access to certain SaaS applications from unmanaged or non-compliant devices. This ensures that only authorized and managed devices can access sensitive corporate SaaS resources, enhancing security posture.

The study guide highlights Tenant Restriction as an essential control for enforcing device compliance in SaaS access policies.

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

One of the four essential steps of a cyber attack is tofind the attack surface. This step involves identifying vulnerabilities, entry points, and targets within an organization’s network or systems that can be exploited by attackers.

The study guide outlines this as a critical phase in the cyber kill chain, where attackers map out potential avenues for compromise.

After the Zscaler Client Connector (ZCC) receives a valid SAML response,Zscaler Internet Access (ZIA)takes over to validate the SAML assertion. Upon successful validation, ZIA issues an authentication token that allows the user to access services securely. This centralized validation ensures authentication integrity and enables seamless policy enforcement across Zscaler services.

When a ZDX custom application is configured with the type set to'Network', the administratorwill not get Disk I/O metricsfor users. Disk I/O metrics relate to local client device performance and are not part of network-type application probes which focus on network latency, server response, and other network-centric measurements.

The study guide notes that Disk I/O is part of endpoint-level monitoring and is not collected by network-type probes, unlike metrics such as Server Response Time or ZDX Score which are network related.

Valid criteria for Access Policy Rules in ZPA includeGroup 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.
