Communication Systems
Whats a common feature of SD-WAN GRE Tunnels and IPSec Tunnels? -
ANSWERProvide secure communication between different network segments
What are the challenges of extending legacy network and security to the
public cloud? - ANSWERCreating VPCs and VNETs add overhead. Increases
attach surface.

intracloud, multi-cloud, hybrid?
What is the purpose of a GRE tunnel in the ZTE? - ANSWERTo load balance
traffic properly
What two items most accurately describe ZT connectors? - ANSWER1. Access
is granted but never shared at the network layer
2. Independent of anyh network for control or trust
Main advantage of using an SD-WAN vendor to connect ot Zscaler over
tranditional routers? - ANSWEROne-click configuration of the connection.
,What prevents unauthorized SD-WAN router connections to the Zscaler
service? - ANSWERThe partner key
Which tunnel types does Zscaler support between a router and a Zscaler data
center? - ANSWERGRE & IPSEC
T/F - GRE Tunnels should always be deployed in pairs for redundancy? -
ANSWERTrue
Private Service Edge - what's the workflow? - ANSWER1. User Connects to
PSE
2. PSE --> Express Route or VPN to ZPA CC or DC Connector
3. Connector to ZS. cloud to validate
Private Service Edge - how to configure? - ANSWER1. Inbound 443, Unique IP,
CC needs to comm with PSE IP and app conn
