Zscaler ZDTA Dumps Questions Answers

Layered defense forces attackers to defeat multiple controls, raising operational cost, time, and chance of detection. Zscaler's architecture layers identity, connectivity, TLS inspection, ATP, sandboxing, DLP, segmentation, and analytics rather than relying on one appliance or single signature set. Option A (Layered defense increases costs to attackers to operate) is correct because layered defense increases attacker cost and decreases attacker efficiency.

Why the other options are incorrect:

B. Layered defense from multiple vendor solutions easily share attacker data: Multiple-vendor layering often creates tool silos and inconsistent telemetry. Zscaler’s point is that integrated controls share context in one platform.

C. Layered defense ensures attackers are prevented eventually: “Eventually prevented” is not a security design. Integrated zero trust tries to break the attack chain early and consistently, not hope one layer catches it later.

D. Layered defense with multiple endpoint agents protects from attackers: Stacking endpoint agents can increase conflict and operational overhead. Zscaler’s model reduces reliance on agent sprawl by enforcing policy in the exchange.

When migrating from an on-premises proxy to Tunnel Mode, leaving legacy browser or system proxy settings in place can create loops or conflicting forwarding paths. Best practice is to enforce no proxy configuration so Client Connector owns traffic steering cleanly through the configured tunnel. Option B (Enforce no Proxy Configuration) is correct because Tunnel Mode should not depend on legacy proxy auto-configuration.

Why the other options are incorrect:

A. Execute a GPO update to retrieve the proxy settings from AD: A GPO can push Windows settings, but using it to reapply old proxy configuration works against Tunnel Mode best practice.

C. Use Web Proxy Auto Discovery (WPAD) to auto-configure the proxy: WPAD auto-discovers proxy settings; it can accidentally preserve legacy proxy behavior during a tunnel-mode migration.

D. Use an automatic configuration script (forwarding PAC file): A PAC file tells the client or browser which proxy path to use for matching destinations.

Trusted Network Detection relies on observable network signals from the endpoint. Hostname/IP resolution, DNS server, and DNS search domain are valid criteria because they indicate whether the device is attached to a known corporate network. Option C (Hostname/IP, DNS Server and DNS Search Domain) is correct because it lists supported trusted-network criteria.

Why the other options are incorrect:

A. DNS Server, DHCP Server and Hostname/IP: DNS Server criteria identify a trusted network by checking whether the endpoint sees expected internal resolver addresses.

B. DHCP Server, DNS Search Domain and Hostname/IP: DNS Search Domain is a trusted-network signal because corporate networks commonly push recognizable suffixes to endpoints.

D. Hostname/IP, DNS Search Domain and DHCP Server: DNS Search Domain is a trusted-network signal because corporate networks commonly push recognizable suffixes to endpoints.
