Zscaler Updated ZDTA Exam Questions and Answers by kylian

Zscaler Access Control Services support Zero Trust by enforcing segmentation and conditional access instead of allowing broad network reach. Preventing lateral movement requires connecting users to specific applications and limiting what they can discover or reach beyond that entitlement. Option B (Access is granted without sharing the network between the originator and the destination application) is correct because segmentation and conditional access are the controls that reduce lateral-movement risk.

Why the other options are incorrect:

A. Trusted network criteria designate the locations of originators which can be trusted: Trusted Network detection decides whether the device is on a known corporate network using signals such as DNS servers, search domains, gateways, or hostname resolution.

C. Cloud firewall policies ensure that only authenticated users are allowed access to destination applications: Zscaler Cloud Firewall enforces network-service and application rules for non-web and firewall-controlled traffic.

D. Connectivity between the originator and the destination application is over IPSec tunnels: IPS inspects traffic inline for exploit signatures and attack patterns, then blocks or resets offending sessions.

Exact Data Match protects structured sensitive data by converting source values into secure hashes before they are used by Zscaler cloud enforcement. The on-premises EDM VM performs indexing locally so raw customer data is not uploaded into the Zscaler cloud. Only hashed values are used for matching. Option B (By using an on-premises VM to index data and only sending hashed values to the cloud) is correct because the VM automates indexing and sends hashed data, not clear sensitive records, to the cloud.

Why the other options are incorrect:

A. By storing sensitive structured data on servers managed by trusted Zscaler staff for enhanced security: Storing raw structured data on Zscaler-managed servers would create unnecessary exposure. EDM avoids this by sending hashed values, not the original data.

C. By requiring customers to manually hash the data and upload it to the cloud: Manual customer hashing is error-prone and not the EDM workflow. The on-premises VM automates hashing/indexing before values are sent to Zscaler.

D. By encrypting sensitive data directly before storing it in the cloud: Encrypting raw sensitive data before cloud storage still implies the data is being stored. EDM avoids that by sending hashes, not the original structured values.

Downloaders are malware whose primary job is to retrieve and install additional payloads. They are frequently used as a first-stage infection because the initial file can be small and then pull ransomware, RATs, infostealers, or other malware after execution. Option C (Downloaders) is correct because a downloader ' s purpose is specifically to deliver other malware.

Why the other options are incorrect:

A. RAT: A remote access trojan gives an attacker interactive control over a compromised host after infection.

B. Maldocs: A malicious document uses macros, embedded objects, or exploit content to run code when opened.

D. Exploitation tool: An exploitation tool attacks a vulnerability. A downloader is the malware type whose purpose is to fetch and install additional malware.

Option A applies least privilege to the east-west workload flow that must remain available. Zscaler explains that microsegmentation uses identity-based, granular policy so each workload communicates only with resources required for its function, while unauthorized communication is blocked. The payroll server should therefore be permitted to reach the database only on TCP 1433, and unrelated servers should have no path to that database. The wiki should also be separated according to its distinct application identity and access requirements. Placing both applications in a broad segment preserves unnecessary reachability and increases the blast radius; IPS signatures do not replace segmentation. A trusted-network condition addresses user context, not server-to-server authorization. Raising a global user-risk threshold likewise does not constrain the compromised payroll workload’s lateral movement. Identity-based service policy directly contains the threat while preserving the required database flow.
