What Links a Secure Cloud Analytics Private Network Monitor Sensor to the Portal?
Short answer
BD Link the private network monitor sensor to the Secure Cloud Analytics portal using the sensor's unique service key and public IP address.
Question
Key Takeaways
The exam tests which identifiers enroll an on-premises Secure Cloud Analytics sensor with the cloud portal; the trap is choosing the private IP address or NAT ID instead of the public IP address and unique service key.
Linking a Cisco Secure Cloud Analytics private network monitor sensor to the portal requires the sensor's public IP address and unique service key. This page confirms those two identifiers and explains why private IP, SSL certificate, and NAT ID are not used for enrollment.
Common mistake: A common mistake is selecting the private IP address (A), assuming internal reachability identifies the sensor; the portal links through the sensor's public IP address or its unique service key, not its private address.
Expert Analysis
Why the Answer Is Correct
Cisco Secure Cloud Analytics links a private network monitor sensor to the portal by identifying it with its public IP address or, when that address cannot be determined, by manually entering the sensor's unique service key. These two values give the portal a way to map the on-premises sensor to the correct tenant and establish the cloud connection. The public IP is the externally visible address the portal can use, while the service key is the unique enrollment identifier for that sensor. Because the question asks for two pieces of information, both B and D are required.
Why the Other Options Are Wrong
A private IP address (A) is only meaningful inside the local network and cannot identify the sensor to the cloud portal. An SSL certificate (C) supports encrypted transport and trust, but it is not the enrollment or linking value requested here. A NAT ID (E) is not a Secure Cloud Analytics sensor-linking field; NAT may affect addressing, but it is not the portal identifier.
Community Comment Notes
ITVI points readers to Cisco's Sensor Advanced Configuration Guide, and Pierre_Bouvier summarizes the required values as "Unique Service Key / Public IP Address." XBfoundX explains that linking is normally done by identifying the sensor's public IP address and that the unique service key is used when the public IP cannot be determined. The comment consensus aligns with B and D, and the same conclusion follows from Cisco's documented sensor-linking procedure.

Exam Strategy
For this multi-select question, focus on what the cloud portal needs to identify an on-premises sensor: an externally visible address or a unique enrollment key. Do not overcomplicate the decision with certificates or NAT identifiers, and select exactly two answers.

XBfoundX 👍 1Onceasensoris installed, it will need to be linked with your portal. This is done by identifying the sensor's public IP address and entering it into the web portal. If you cannot determine the sensor's public IP address, you can manually link the sensor to your portal using its unique service key. The sensor can connect to the following portals: l https://sensor.ext.obsrvbl.com (US) l https://sensor.eu-prod.obsrvbl.com (EU) l https://sensor.anz-prod.obsrvbl.com (Australia)
