ZDTA Dumps with Practice Exam Questions Answers

For a new cloud-gen firewall configuration, a default block posture is the safer baseline. Administrators should explicitly permit required business traffic and preserve required Zscaler service rules instead of leaving a broad default allow that weakens least-privilege design. Option A (Block all traffic) is correct because block all traffic is the recommended default-deny stance.

Why the other options are incorrect:

B. Permit all traffic: Permit-all firewall posture lets unexpected services leave the network until later rules stop them.

C. Disable the firewall: Disabling the firewall removes the enforcement layer instead of creating a safe default rule set.

D. Allow only web traffic (ports 80/443): Allowing only ports 80/443 would ignore valid non-web business traffic that may need explicit firewall rules.

Option C tests both the observed behavior and the controls needed to see it. Zscaler notes that attackers use SSL/TLS to conceal data exfiltration and command-and-control traffic, making decryption and inspec tion necessary for visibility. The Web Insights filters distinguish TLS-inspected from uninspected transactions, so the team can confirm whether suspicious outbound flows were actually decrypted. ZIA threat and DLP evidence should be correlated with ZPA user-activity fields to identify unusual private-application access by the same user or device. The team should then verify that DLP and botnet policies covered those decrypted sessions and review any exceptions. Option B examines only part of the evidence. Raising firewall severity changes labeling rather than validating protection, while broad Sandbox reanalysis focuses on downloaded files and does not confirm encrypted egress coverage. Correlation plus policy validation reveals the actual control gap.

Tamper proofing prevents users or malware from disabling or altering Client Connector after installation. The installer must include the explicit anti-tampering flag to activate that protection during deployment. Option D (--enableAntiTampering) is correct because --enableAntiTampering is the command-line parameter for this control.

Why the other options are incorrect:

A. --secureInstall: --secureInstall sounds like a hardening flag, but the ZCC installer parameter for tamper proofing is --enableAntiTampering.

B. --antiTamper: Anti-tampering prevents local users from disabling or removing Client Connector protections.

C. --disableTampering: Anti-tampering prevents local users from disabling or removing Client Connector protections.

Encrypted traffic must be decrypted before platform services can inspect headers, payloads, files, and content for policy enforcement. TLS Decryption is the Zscaler platform service that converts encrypted sessions into inspectable traffic inside the proxy architecture, then re-encrypts the traffic after policy decisions are applied. Option B (TLS Decryption) is correct because visibility into encrypted communications depends on TLS Inspection/Decryption, not on the downstream policy module itself.

Why the other options are incorrect:

A. Policy Framework: Policy Framework decides what action to take. TLS Inspection is the feature that first makes encrypted traffic visible for those policies.

C. Reporting and Logging: Reporting and logging record what happened. They cannot inspect encrypted payloads unless TLS Inspection has already exposed the content.

D. Device Posture: Device Posture evaluates endpoint health. It does not decrypt traffic or provide visibility into HTTPS payloads.

Z-Tunnel with Local Proxy creates a local loopback proxy on the endpoint. Applications send traffic to that loopback listener, and Client Connector then forwards the traffic toward Zscaler according to profile and policy. Option C (ZTunnel with Local Proxy) is correct because the loopback address behavior is specific to ZTunnel with Local Proxy.

Why the other options are incorrect:

A. Enforced PAC mode: Enforced PAC pushes proxy rules to the system or browser. The loopback forwarding behavior is specifically Tunnel with Local Proxy.

B. ZTunnel - Packet Filter Based: Z-Tunnel is Client Connector tunneling used to steer endpoint traffic to the Zscaler cloud.

D. ZTunnel - Route Based: Z-Tunnel is Client Connector tunneling used to steer endpoint traffic to the Zscaler cloud.
