Trust Exchange (ZTE) Questions with Correct Answers & Detailed
Rationales
Section 1: Zero Trust Exchange & Architecture
1. What is a common feature of SD-WAN GRE tunnels and IPSec
tunnels?
A. They provide application-layer encryption only
B. They provide secure communication between network segments
C. They replace firewalls
D. They eliminate routing requirements
Correct Answer: B
Rationale: Both GRE and IPSec tunnels enable secure communication
between distributed network segments. IPSec encrypts traffic, while
GRE encapsulates traffic and can be paired with IPSec for security.
2. What are the challenges of extending legacy network and security
to the public cloud?
A. Reduced attack surface
B. Increased simplicity
C. Creating VPCs/VNETs adds overhead and increases attack surface
D. Automatic encryption
,Correct Answer: C
Rationale: Extending legacy infrastructure to cloud environments
increases complexity and expands the attack surface due to added
VPCs, routing, and security controls.
3. What are use cases for Zero Trust Cloud?
A. Only intranet access
B. Workload to internet, intracloud, multi-cloud, hybrid
environments
C. Email encryption only
D. DNS filtering only
Correct Answer: B
Rationale: Zero Trust Cloud supports workload-to-internet,
intracloud, multi-cloud, and hybrid connectivity using identity-
based access.
4. What is the purpose of a GRE tunnel in Zero Trust Exchange
deployments?
A. Encrypt traffic
B. Load balance traffic properly
C. Replace IPS
D. Disable firewall inspection
,Correct Answer: B
Rationale: GRE tunnels help distribute traffic efficiently across
multiple paths and are commonly deployed in pairs for redundancy.
5. Which tunnel types does Zscaler support between a router and a
data center?
A. MPLS and BGP
B. SSL and TLS
C. GRE and IPSec
D. SSH and FTP
Correct Answer: C
Rationale: Zscaler supports GRE and IPSec tunnels for router-to-
cloud connectivity.
6. True or False: GRE tunnels should always be deployed in pairs for
redundancy.
Correct Answer: True
Rationale: Deploying GRE tunnels in pairs ensures failover and high
availability.
Section 2: Private & Virtual Service Edge
, 7. Which platforms support Virtual Service Edge (VSE)?
A. ESXi, Hyper-V, AWS, Azure, GCP
B. Linux only
C. Cisco IOS only
D. Physical appliance only
Correct Answer: A
Rationale: VSE supports hypervisors and major cloud platforms for
flexible deployment.
8. What performance can be expected from VSE during SSL
inspection?
A. 100 Mbps
B. 300 Mbps
C. 600 Mbps
D. 2 Gbps
Correct Answer: C
Rationale: Typical SSL inspection performance for VSE is
approximately 600 Mbps.
9. What are the two deployment options for a Physical Service Edge?
A. Inline and Transparent
B. Single-arm and Dual-arm
C. GRE and IPSec
D. Static and Dynamic
