C1000-189 Exam Dumps : IBM Instana Observability v1.0.277 Administrator – Professional

IBM Instana agents use HTTPS, the industry standard secure protocol, to transmit telemetry data to Instana’s backend servers or clusters. Instana documentation says: "All agent-to-backend traffic is encrypted and transmitted via HTTPS, meeting data confidentiality and compliance requirements." The use of HTTPS prevents unauthorized data interception by using strong TLS encryption on every packet exchanged between agent and backend, regardless of whether the deployment is on-premises or SaaS. FTP, SSH, and NFS are protocols for file transfer, system access, or storage mounting but are never used for telemetry transmission in Instana's architecture. Secure HTTP is essential for privacy by design, is policy-enforced, and supports audit-friendly observability in all supported Instana versions per IBM standards.

Within Instana, action script sensors execute administrative or diagnostic commands in context of the runtime environment that hosts the Instana agent. The current IBM documentation specifies: "Action scripts are executed by the Instana agent process on the monitored host using the permissions and context of that agent." The agent serves as a self-contained runtime capable of executing defined scripts, invoking system-level or application-specific logic safely within its host boundary. This design enhances automation and extensibility while respecting host-level security because the execution does not escalate privileges beyond the agent’s service account. Instana ensures that scripts running within the agent context inherit its environment variables and operational limits, guaranteeing consistency and preventing user-specific execution inconsistencies. Other answer options (service agent, container, or logged-in user) do not reflect the actual architectural control documented by IBM, where the primary host agent controls all action-based script invocations.

Instana’s Synthetic Monitoring module allows administrators to script user journeys and API checks to validate service performance and uptime. According to official IBM documentation, "Synthetic monitoring API scripts use JavaScript as the scripting language for configuring user flows and custom API tests." Instana has designed its synthetic user interface to interpret JavaScript natively which provides powerful, flexible constructs for simulating user interactions, custom API payloads, test logic, and error handling. This ensures broad compatibility with real browser environments and highly customizable synthetic scenarios. Java, Python, and Go are not supported for browser-based or synthetic API scripting in Instana’s synthetic monitors. JavaScript is chosen for its ubiquity and ease of integration with DOM-like and API interaction patterns, supporting the most common web-based automation needs as described in the documentation.
