Zscaler Updated ZDTA Exam Questions and Answers by addison

ZIA Malware Protection is an inline security control that blocks malicious files or objects detected through signatures, reputation, and threat-intelligence checks. The policy action must stop the malicious transfer rather than simply route, isolate, or change TLS behavior. Option A (Malware protection) is correct because Block is the malware policy action that prevents the identified malicious content from reaching the user.

Why the other options are incorrect:

B. File reputation: File reputation checks whether an object is known good or bad. The question’s answer is about the behavior-analysis control for unknown files.

C. SHA-256 hashing: SHA-256 hashing is a cryptographic integrity/hash function. It does not execute a suspicious file or observe behavior the way Cloud Sandbox does.

D. Site reputation: Site reputation scores web destinations. It does not detonate or analyze the file itself.

ZDX application scoring aggregates the user experience observed during the selected time period. The tested calculation uses each user's lowest experienced value for that application, then averages those lowest values across the users who accessed it. This prevents a brief severe degradation from being hidden by otherwise healthy samples. Option A (Zscaler takes all the users that accessed the application for the selected time period and finds the lowest value each user would have experienced for the application. The lowest values for each user are added together and divided by the number of users) is correct because it describes the user-based lowest-value aggregation model.

Why the other options are incorrect:

B. Zscaler considers a single user that accessed the application for the selected time period and finds the lowest value that user would have experienced for the application. The lowest values for that user are added together and divided by the number of all users in the organization: This only considers one user, then divides by all users, which would distort the application score. ZDX computes the app score from all users who accessed the app in the selected period.

C. Zscaler takes sample set of users that accessed the application for the selected time period and finds the lowest value each user would have experienced for the application. The lowest values for each user are added together and divided by the number of sample set of users: A sample set could miss users with poor experience. The tested ZDX calculation uses all users who accessed the application, then averages their lowest experienced values.

D. Zscaler takes the lowest value for each application for a set of users, for time intervals based on the selected time range. The application with the lowest value represents your applications score for that time interval: This shifts the calculation from users to applications. ZDX application score is based on users’ lowest experience for that application, not on picking the lowest application across a set.

A ZDX custom application of type Network measures network-path and application reachability metrics, not local storage performance. Metrics such as server response time, ZDX Score, and gateway information are aligned to network/application experience. Disk I/O is an endpoint hardware metric and is not produced by a network-type custom application probe. Option D (Disk I/O) is correct because Disk I/O is outside the network probe metric set.

Why the other options are incorrect:

A. Server Response Time: Server Response Time measures how long the destination application takes to respond to a probe or request.

B. ZDX Score: ZDX Score summarizes user experience for an application, location, or user from measured telemetry.

C. Client Gateway IP Address: Client Gateway IP identifies the gateway or egress point seen from the client path.

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.
