1. What is the primary role of the Zscaler Private Service Edge (PSE)?
To provide localized policy enforcement and inspection for private apps and
internet access when cloud connectivity is restricted.
2. Which component determines traffic routing decisions for Zscaler Client
Connector?
Zscaler Central Authority (CA) based on client location, DNS, and policy.
3. Which Zscaler feature improves performance when using a local Service Edge?
DNS resolution closest to the Service Edge and GRE/IPsec tunneling from edge
routers.
4. What does the provisioning key do in a Private Service Edge deployment?
Registers and authenticates the Service Edge with Zscaler cloud during
bootstrapping.
5. Why is EM2 used in VSE deployments?
It handles load-balanced traffic between the internal proxy and external users.
,6. What does the Partner Key prevent in SD-WAN integrations?
Unauthorized devices or routers from establishing tunnels with Zscaler
Enforcement Nodes.
7. What are the benefits of deploying a Virtual Service Edge (VSE)?
Flexible deployment in hypervisors and public clouds; ideal for air-gapped or
regulatory environments.
8. What is the maximum throughput expected on SSL-inspected traffic through a
Virtual Service Edge?
600 Mbps
9. What component performs traffic policy enforcement in the Zscaler Zero Trust
Exchange?
Zscaler Enforcement Node (ZEN)
10. What must be enabled in an SD-WAN router to route internet-bound traffic
to Zscaler?
GRE/IPSec tunneling and a valid forwarding policy to ZENs or Service Edges
11. What happens if both GRE tunnels from a branch fail?
Traffic may fall back to a secondary method (e.g., PAC-based proxy or tunnel-
less fallback), depending on configuration.
12. Which tool is used to monitor health status and logs of a PSE or VSE
instance?
Zscaler Admin Portal > Administration > Service Edges
,13. What distinguishes a PSE from a VSE in terms of use case?
PSE is physical/on-prem; VSE is virtual and cloud-hosted for agile deployments.
14. What is the use of the Service Edge Group in configuration?
To logically group PSE/VSEs by region or function for easier policy and routing
control.
15. What cloud providers support VSE deployment?
AWS, Azure, GCP, VMware ESXi, and Hyper-V
Scenario 1: Branch traffic is not reaching Zscaler via GRE tunnel
Symptoms:
• Users at a branch office cannot access the internet.
• Traffic is supposed to route through a GRE tunnel to Zscaler.
• Zscaler dashboard shows no traffic logs from that location.
Checklist:
Confirm GRE tunnel configuration (destination IP, source IP, MTU).
Verify tunnel status on branch router.
Check if Partner Key is configured and matches in Zscaler portal.
Ensure firewall rules allow GRE (protocol 47).
Use traceroute or ping to test reachability of the ZEN.
Scenario 2: Zscaler Client Connector fails to connect users to Private Apps
Symptoms:
, • Client Connector is online, but users cannot access internal applications
(ZPA).
• DNS resolution is working, but connections time out.
Checklist:
Check App Connector health status in the ZPA portal.
Verify the App Segment includes the app’s FQDN or IP and is mapped to the
right connector group.
Ensure the connector has outbound access to Zscaler Cloud (ports 443, TLS).
Check ZPA Access Policies and ensure correct identity group is allowed.
Run ZPA Diagnostic Toolkit from the user’s machine.
Scenario 3: High latency reported from VSE-deployed region
Symptoms:
• Users routed to a Virtual Service Edge (VSE) are reporting slow browsing.
• Latency appears high in ZDX.
Checklist:
Check VSE system health (CPU, memory, SSL queue length).
Verify EM2 is correctly routing load-balanced traffic.
Run iperf test between users and VSE.
Ensure the virtual host’s underlying infrastructure (e.g., AWS EC2 or Azure
VM) meets Zscaler’s minimum requirements.
Review SSL inspection settings—disable temporarily to isolate issue.
Scenario 4: SD-WAN router fails to establish IPSec tunnel to ZEN
Symptoms:
• IPSec tunnel fails to establish after router replacement.
