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

OTLP (OpenTelemetry Protocol) enables modern, standards-based telemetry with Instana for traces and metrics. The official IBM Instana documentation explains that enabling OTLP support should be done during installation or upgrade viaHelm, using either values set in a YAML file or via the --set command line argument. This method is described as, "To enable OTLP, use Helm with the provided chart and set OTLP values in your values.yaml or with the --set flag." Helm automation allows administrators to easily manage, update, and version-control agent and collector configuration at scale—especially in Kubernetes environments. It is favored because it is compatible with Instana’s operator and dynamic config approaches. Manual edits in settings.hcl or params.yaml are not recommended or officially documented for enabling OTLP streams. Multiple tracers relate to instrumentation and are not for enabling the protocol itself. Using Helm provides a streamlined, repeatable and supported approach – per IBM Instana deployment best practices.

The dashboard permissions model in Instana ensures secure, user-specific management of visual analytics content. IBM confirms: "By default, dashboards created by a user are private and accessible only to their creator; they can be shared explicitly with other users or teams for viewing or editing." This model supports controlled collaboration while maintaining ownership accountability. The owner may later assign permissions within the UI, typically under the Dashboard Sharing and Permissions option, defining read or write privileges per user or group. Default private scoping avoids accidental data exposure yet allows managed distribution in team settings. Public dashboards may be intentionally created as shared artifacts, but sharing must always be a conscious user action. These principles align with enterprise-grade security requirements described in the Permissions section of the dashboards documentation and remain unchanged across Instana versions.

According to IBM Instana Observability (v1.0.307 and earlier), stanctl cluster backup is a built-in utility and command-line tool to back up system state and operational data from an Instana cluster. The verified procedure reads: "stanctl cluster backup saves configuration, operational state, and selected monitoring data into an archive file located in the current working directory." This archive is designed for disaster recovery and migration, containing all crucial files needed for restoring Instana to a consistent state. Disk snapshots (A) are separate and handled by storage appliances. Option B describes pre-backup preparation rather than the actual result. Remote backup (C) operations require remote execution configuration and are not part of the default cluster backup. Thus, D is correct as per documentation, which emphasizes bringing together all cluster backup data in a portable .tar or .zip archive for safe storage or transfer.
