Refer to the exhibit.

The correct expression isaccessPoints[0].interfaces[1] .macAddress. The JSON object contains a top-level key namedaccessPoints, whose value is an array. Array indexing begins at zero, soaccessPoints[0]selects the first access point object,ap-west-1. Inside that object, theinterfaceskey also contains an array. Therefore,interfaces[1] selects the second interface object, which hasslot: 1,status: "down", andmacAddress: "CC:FA:00:11:22:34". The final selector,.macAddress, returns that MAC address value.

This structure is directly aligned with Cisco automation workflows, where RESTCONF and Catalyst Center APIs exchange structured data in JSON. Cisco documents that Catalyst Center REST API payloads are JSON-formatted, and its example describes JSON as key-value data separated by colons. Cisco also states that Catalyst 9800 RESTCONF uses structured XML or JSON with YANG models for programmatic device access. Option B selectsap-east-2. Option C selects the first interface onap-west-1. Option D references a non-existent second interface onap-east-2.
