Zscaler ZS-DTA Online Questions & Answers

• Question 91:

  Which types of Botnet Protection are supplied by Advanced Threat Protection?

  A. Malicious file downloads, Command traffic (sending / receiving), Data exfiltration
  B. Connections to known C&C servers, Command traffic (sending / receiving), Unknown C&C using AI /ML
  C. Connections to known C&C servers, Detection of phishing sites, Access to spam sites
  D. Vulnerabilities in web server applications, Unknown C&C using AI/ML, Vulnerable ActiveX controls
  B. Connections to known C&C servers, Command traffic (sending / receiving), Unknown C&C using AI /ML

  ---

  Explanation

  Advanced Threat Protection provides botnet protection by monitoring connections to known Command and Control (C&C) servers, inspecting command traffic (sending and receiving), and detecting unknown C&C servers using AI/ML techniques. This comprehensive approach helps in identifying and blocking botnet activities effectively.

  The study guide details these mechanisms as key elements of the botnet protection feature set in ATP.

• Question 92:

  What is the recommended default rule for the cloud-gen firewall configuration when deploying a new ZIA tenant?

  A. Block all traffic
  B. Permit all traffic
  C. Disable the firewall
  D. Allow only web traffic (ports 80/443)
  B. Permit all traffic

  ---

  Explanation

  The recommended initial configuration for a new ZIA tenant is to permit all traffic in the cloud-gen firewall.

  This ensures that legitimate traffic is not unintentionally blocked during early deployment and policy tuning, allowing administrators to gradually introduce granular controls as visibility improves.

• Question 93:

  What does Zscaler Advanced Firewall support that Zscaler Standard Firewall does not?

  A. Destination NAT
  B. FQDN Filtering with wildcard
  C. DNS Dashboards, Insights and Logs
  D. DNS Tunnel and DNS Application Control
  D. DNS Tunnel and DNS Application Control

  ---

  Explanation

  Zscaler Advanced Firewall supports DNS Tunnel and DNS Application Control, capabilities that are not available in the Standard Firewall. This enhances detection and control of DNS-based threats and allows granular enforcement over DNS queries and responses to prevent data exfiltration and command and control activities.

• Question 94:

  What is the scale used to represent a users Zscaler Digital Experience (ZDX) score?

  A. 1-100
  B. 1-10
  C. 1 - 1000
  D. 0 - 50
  A. 1-100

  ---

  Explanation

  The ZDX Score is calculated on a scale from 1 (worst) to 100 (best), where lower values indicate poorer digital experience and higher values indicate optimal performance.

• Question 95:

  Administrators handle sensitive configuration, while ordinary users access protected services.

  How should administrative sign-on be governed?

  A. Administrative sign-on should use the same unrestricted policy as ordinary users
  B. Administrative sign-on should use a dedicated policy with stronger controls
  C. Administrative sign-on should bypass the identity provider during business hours
  D. Administrative sign-on should rely on a shared local credential
  B. Administrative sign-on should use a dedicated policy with stronger controls

  ---

  Explanation

  Privileged access warrants a dedicated sign-on policy with controls appropriate to administrative risk. Shared credentials and broad bypasses reduce accountability and protection.

• Question 96:

  The Security Alerts section of the Alerts dashboard has a graph showing what information?

  A. Top 5 Malware Programs Detected
  B. Top 5 Viruses by Region
  C. Top 5 Threats by Systems Impacted
  D. Top 5 Unified Threat Yara Options
  C. Top 5 Threats by Systems Impacted

  ---

  Explanation

  The graph in the Security Alerts section displays the Top 5 Threats by Systems Impacted, highlighting which threats have affected the most endpoints over the selected time period.

• Question 97:

  What does TLS Inspection for Zscaler Internet Access secure public internet browsing with?

  A. Storing connection streams for future customer review.
  B. Removing certificates and reconnecting client connection using HTTP.
  C. Intermediate certificates are created for each client connection.
  D. Logging which clients receive the original webserver certificate.
  C. Intermediate certificates are created for each client connection.

  ---

  Explanation

  TLS Inspection in Zscaler Internet Access secures public internet browsing by creating intermediate certificates for each client connection. This Man-In-The-Middle approach enables Zscaler to decrypt and inspect encrypted traffic for threats and policy compliance while still maintaining secure connections with the client. The intermediate certificate acts as a trusted entity between the client and the real server during inspection.

• Question 98:

  An organization has more than one ZIA instance, each on different clouds. The organization is using the same login domain for both and upon login users are given this menu in ZCC asking which cloud they would like to join.

  What steps could an Administrator take to avoid having this menu appear?

  A. Customize an MSI version of the ZCC file specifying the USERDOMAIN variable.
  B. Customize an MSI version of the ZCC file specifying the CLOUDNAME variable.
  C. Federate the login domain between two different IDP instances.
  D. Create only one SAML integration with the desired ZIA instance.
  B. Customize an MSI version of the ZCC file specifying the CLOUDNAME variable.

  ---

  Explanation

  To avoid prompting users with a cloud selection menu in the Zscaler Client Connector (ZCC), administrators should customize the MSI installation package with the CLOUDNAME parameter. This setting ensures the ZCC automatically connects to the correct ZIA cloud instance without user intervention. The CLOUDNAME corresponds to the designated cloud name for the organization's ZIA tenant, effectively bypassing the prompt. This is outlined under Zscaler's deployment and configuration instructions for ZCC.

• Question 99:

  Fundamental capabilities needed by other services within the Zscaler Zero Trust Exchange are provided by which of these?

  A. Access Control Services
  B. Digital Experience Monitoring
  C. Cyber Security Services
  D. Platform Services
  D. Platform Services

  ---

  Explanation

  Platform Services provide the fundamental capabilities needed by other services within the Zscaler Zero Trust Exchange. These services include core functions such as identity management, policy management, logging, reporting, and API integrations that underpin and support the other service modules. The study guide clarifies that Platform Services form the backbone of the Zscaler Zero Trust Exchange, enabling seamless interoperability and foundational support for security and access services.

• Question 100:

  What is the recommended minimum number of App connectors needed to ensure resiliency?

  A. 2
  B. 6
  C. 4
  D. 3
  A. 2

  ---

  Explanation

  The recommended minimum number of App connectors to ensure resiliency in Zscaler Private Access is. 2 Having at least two App connectors provides redundancy, so if one connector fails or is unavailable, the other can continue to provide access without interruption. This recommendation is critical to maintaining high availability and fault tolerance for internal application access. The study guide specifies this minimum to ensure continuity and reliability of application access through ZPA.
