Question

QUESTION 29 Drag and Drop Question: Refer to the exhibit. A system administrator has installed a Linux-based alarm system in their home that can execute a Bash shell script when an intruder is detected. The task is to complete the script by dragging the correct code snippets from the left onto the item numbers on the right that match the missing sections in the exhibit. Not all code snippets are used. The specific exhibit (script/code with numbered placeholders `<item 1>` to `<item 5>`) for this drag-and-drop task is not provided in the current context. Available options for dragging (from the Answer Area on page 5): `application/xml`, `application/json`, `/rooms`, `name`, `title`, `userName`, `/memberships`, `personEmail`, `/members`, `/spaces`.

Explanation

This question tests the ability to complete a Bash shell script that uses the Cisco Webex (formerly Spark) REST API to send an automated alert when a home alarm system detects an intruder. It requires matching correct API endpoints, field names, and HTTP content-type headers to the correct placeholders in the script.

Approach. The script makes HTTP requests via curl to the Cisco Webex REST API. The correct content-type header is application/json (not application/xml) because Webex's API exclusively uses JSON payloads. To create a notification room, the endpoint is /rooms (or /spaces - Webex uses both, but /rooms is the canonical v1 endpoint). To add a recipient to that room, the endpoint is /memberships, and the recipient is identified using the personEmail field. The room's display name uses the title field in the JSON body. These five pieces - application/json, /rooms, title, /memberships, and personEmail - are the correct selections for items 1–5 respectively.

Concept tested. Integration of REST API calls (Cisco Webex API) into a Bash automation script - specifically correct HTTP Content-Type headers, Webex API endpoint paths (/rooms, /memberships), and JSON field names (title, personEmail) used to programmatically create a space and notify a user upon an alarm event.

Reference. Cisco Webex REST API documentation (https://developer.webex.com/docs/api/v1/rooms and /memberships); CompTIA CyberOps Associate / Cisco CyberOps Associate (CBROPS 200-201) - automation and scripting with REST APIs.
