Zscaler Updated ZDTA Exam Questions and Answers by ivo

Legacy firewalls introduce performance risk because they were designed around centralized perimeter enforcement and hardware capacity limits. Cloud and remote-work traffic creates encrypted, high-volume flows that can overwhelm appliance-based inspection and force inefficient backhauling. Option A (Performance issues) is correct because performance degradation is a real business risk of legacy firewall architecture.

Why the other options are incorrect:

B. Reduced management: Reduced management would be an operational benefit, not a business risk introduced by legacy firewalls.

C. Low costs: Low cost is a benefit claim, while legacy firewall estates usually add hardware, scaling, and maintenance cost.

D. Low licensing support: Licensing support is a commercial concern, not the main architectural risk tested in the legacy-firewall question.

ZDX Score is a normalized digital-experience score used to represent how well a user or application is performing. It is expressed on a 1-to-100 scale, making degraded application, network, and endpoint experience easy to compare across users, locations, and time windows. Option A (1-100) is correct because 1-100 is the ZDX scoring range.

Why the other options are incorrect:

B. 1-10: A 1-10 scale is too coarse for ZDX. ZDX uses a 1-100 score so administrators can see more granular experience changes.

C. 1 - 1000: A 1-1000 scale would imply excessive precision that ZDX does not present. The product score is the simpler 1-100 user-experience scale.

D. 0 - 50: A 0-50 range is not the ZDX scale. ZDX scores are represented on a 1-100 scale.

ZPA Access Policy rules use identity, user/group, device posture, and contextual signals to decide private-application access. Valid criteria are enforcement attributes that ZPA can evaluate, such as group membership, risk score, domain-joined state, and certificate trust. Option B (Yes. Controls for segmentation and conditional access are part of the Access Control Services) is correct because all listed criteria are legitimate policy inputs for ZPA access decisions.

Why the other options are incorrect:

A. No. Access Control Services will only control access to the Internet and cloud applications: Access Control Services are not limited to internet and cloud-app access. They also include segmentation and conditional access patterns that reduce lateral movement.

C. Yes. The Cloud Firewall will detect network segments and provide conditional access: Zscaler Cloud Firewall enforces network-service and application rules for non-web and firewall-controlled traffic.

D. No. The endpoint firewall will detect network segments and steer access: Endpoint firewalls can filter traffic locally on a device. The Zscaler Access Control suite prevents lateral movement through segmentation and conditional access, not by relying on each endpoint firewall.

A URL Filtering Caution action is designed for web-style requests where the user can be warned before proceeding. The supported request methods tested here are Connect, GET, and HEAD, which align with browser-driven web access and HTTPS tunnel establishment. Option A (Connect, Get, Head) is correct because those methods are valid for the Caution action.

Why the other options are incorrect:

B. Options, Delete, Put: OPTIONS, DELETE, and PUT are HTTP methods, but the canonical REST basics in the guide include GET, POST, PUT, and DELETE.

C. Get, Delete, Trace: TRACE is an HTTP diagnostic method and is not part of the standard REST method set emphasized for Zscaler automation.

D. Connect, Post, Put: CONNECT is proxy tunneling behavior. REST API basics focus on resource methods such as GET, POST, PUT, and DELETE.
