Which component is involved in connecting from PSE to ZPA CC or DC Connector?

The correct answer involves the use of Express Route or VPN, which are both critical components for establishing a secure connection between the Private Service Edge (PSE) and the Zscaler Private Access (ZPA) Control or Data Connector.

When organizations deploy Zscaler, they often require secure and reliable connections from their internal networks to Zscaler’s cloud services. Express Route and VPN are commonly utilized to meet this requirement by creating private or encrypted connections, providing a safe pathway for sensitive data and applications to traverse.

Express Route is a service that enables direct connectivity to Zscaler's cloud, bypassing the public internet and ensuring higher performance and reliability. VPN provides encrypted access over the internet, making it suitable for securely connecting remote users or devices to Zscaler services without exposing data to potential interception.

In contrast, while options such as a direct Internet connection, public IP routing schemes, or local proxy servers may offer connectivity options, they do not inherently provide the necessary security and reliability features that Express Route or VPN offers in this context. These alternatives lack the focused design for secure communication that a VPN or Express Route provides, which is crucial in environments requiring stringent data protection and seamless access.
