QUESTIONS
1. What is the primary function of Zscaler Internet Access (ZIA)?
A. To provide on-premises firewall protection
B. To manage endpoint antivirus solutions
C. To deliver cloud-native secure internet and web access for users
D. To replace VPN concentrators for remote desktop sessions
E. To monitor internal server-to-server traffic only
CORRECT ANSWER: C. To deliver cloud-native secure internet and web
access for users
EXPERT RATIONALE: ZIA is Zscaler's cloud-delivered security platform that inspects
all internet-bound traffic inline, providing secure web gateway, firewall, sandboxing, and
DLP capabilities without requiring on-premises appliances.
2. What does ZPA stand for in the Zscaler portfolio?
A. Zscaler Proxy Architecture
,B. Zscaler Private Access
C. Zero Perimeter Application
D. Zscaler Policy Agent
E. Zero Proxy Access
CORRECT ANSWER: B. Zscaler Private Access
EXPERT RATIONALE: ZPA stands for Zscaler Private Access, a cloud-native Zero
Trust Network Access (ZTNA) solution that provides secure access to private
applications without placing users on the network.
3. Which architecture principle does Zscaler's platform primarily follow?
A. Hub-and-spoke network design
B. Castle-and-moat security model
C. Zero Trust Architecture
D. Flat network topology
E. Perimeter-based defense model
CORRECT ANSWER: C. Zero Trust Architecture
EXPERT RATIONALE: Zscaler is built on Zero Trust principles — no user, device, or
application is trusted by default. Every access request is verified based on identity,
context, and policy before granting access.
4. What is the Zscaler Zero Trust Exchange?
A. A physical data center appliance
B. An on-premises proxy server
C. The cloud platform connecting users, devices, and applications securely
D. A legacy VPN replacement tool only
E. A standalone endpoint protection agent
CORRECT ANSWER: C. The cloud platform connecting users, devices, and
applications securely
,EXPERT RATIONALE: The Zscaler Zero Trust Exchange is the core cloud platform that
acts as an intelligent switchboard — connecting users and devices to applications and
data securely without exposing them to the internet.
5. Which of the following best describes a Zscaler Enforcement Node (ZEN)?
A. An agent installed on user endpoints
B. A cloud-based point of presence where traffic is inspected
C. A hardware appliance deployed in customer data centers
D. A DNS resolver node
E. A load balancer for on-premises servers
CORRECT ANSWER: B. A cloud-based point of presence where traffic is
inspected
EXPERT RATIONALE: ZENs are Zscaler's globally distributed cloud nodes where user
traffic is forwarded for full inline inspection including SSL, malware scanning, DLP, and
policy enforcement.
6. What forwarding method sends traffic to ZIA using a lightweight agent on the
endpoint?
A. GRE Tunnel
B. IPSec Tunnel
C. Zscaler Client Connector (formerly Z-App)
D. PAC File forwarding
E. BGP route advertisement
CORRECT ANSWER: C. Zscaler Client Connector (formerly Z-App)
EXPERT RATIONALE: Zscaler Client Connector is an endpoint agent that automatically
forwards traffic to the nearest ZEN for inspection, ensuring consistent policy
enforcement regardless of user location.
7. Which traffic forwarding method is typically used for branch office traffic to
ZIA?
, A. Zscaler Client Connector only
B. Direct internet breakout
C. GRE or IPSec tunnels from the branch router or firewall
D. MPLS to headquarter proxy
E. DNS-based redirection
CORRECT ANSWER: C. GRE or IPSec tunnels from the branch router or
firewall
EXPERT RATIONALE: Branch offices typically forward traffic to ZIA using GRE or
IPSec tunnels configured on local routers or firewalls, allowing all branch traffic to be
inspected in the cloud without needing endpoint agents on every device.
8. What is the purpose of a PAC (Proxy Auto-Configuration) file in a Zscaler
deployment?
A. To authenticate users to Active Directory
B. To configure DNS resolution for Zscaler nodes
C. To instruct browsers to forward web traffic to the Zscaler proxy
D. To assign IP addresses to Zscaler enforcement nodes
E. To encrypt traffic between endpoints
CORRECT ANSWER: C. To instruct browsers to forward web traffic to the
Zscaler proxy
EXPERT RATIONALE: A PAC file is a JavaScript file that tells browsers which proxy
server to use for different traffic destinations. In ZIA deployments, PAC files direct
browser traffic to Zscaler enforcement nodes for inspection.
9. In ZPA, what component is deployed in the data center or cloud to broker
application access?
A. Zscaler Client Connector
B. App Connector
C. ZEN Node
