What will cause a connector to fail to establish a connection with the cloud gateway during the deployment of a new ZTNA Connector in a data center?

Show Suggested Answer Hide Answer
Suggested Answer: B

A ZTNA Connector requires a stable and direct connection to the cloud gateway. When the connector is deployed behind a double NAT (Network Address Translation), it can cause issues with reachability and session establishment because the cloud gateway may not be able to properly identify and communicate with the connector. Double NAT can interfere with secure tunneling, IP address resolution, and authentication mechanisms, leading to connection failures. To resolve this, the connector should be placed in a network segment with a single NAT or a public IP assignment.

Wait, can a double NAT really block a connection? Sounds odd!

High latency? That's a common culprit for sure.

Dynamic IPs shouldn't be an issue if configured right.

I think double NAT is a big problem too.

A misconfigured DNS can definitely cause issues.

High latency (D) could impact performance, but I’m not convinced it would completely prevent a connection from being established.

I'm not entirely sure, but I feel like using a dynamic IP address (C) might cause issues too, especially if it changes frequently.

I think we had a practice question about NAT issues before, and B could definitely be a problem if the connector is behind double NAT.

I remember we discussed how DNS misconfigurations can really mess up connections, so A seems likely.
