A Cisco Secure Cloud Analytics administrator is setting up a private network monitor sensor to monitor an on-premises environment. Which two pieces of information from the sensor are used to link to…

The private IP address is used within the local network for communication but is not directly used by the cloud portal for linking, as the cloud portal needs to communicate over the public internet.

The unique service key acts as a secure identifier and authentication token, ensuring that the private network monitor sensor can securely register and communicate with the correct Cisco Secure Cloud Analytics portal instance. This key helps to establish trust and link the sensor to the user's account.

An SSL certificate is used for secure communication (encryption and authentication) between the sensor and the cloud portal, but it's part of the secure connection, not the primary pieces of information used *to link* the sensor itself in the sense of unique identification and addressability from the cloud.

The public IP address of the sensor is necessary for the Cisco Secure Cloud Analytics cloud portal to initiate and maintain communication with the on-premises sensor over the internet. This allows the cloud service to reach the sensor to collect data or manage its configuration.

NAT ID is not a standard term used for linking Cisco Secure Cloud Analytics sensors to the portal; while NAT might be involved, "NAT ID" is not the required linking information.
