IBM C1000-189 Exam Syllabus Topics:
TopicDetails
Topic 1
  • Operations: This section of the exam measures the skills of Application Monitoring Specialists and covers daily operational tasks for managing Instana environments. It includes configuring website and application monitoring, handling synthetic monitoring, and creating incidents, issues, and alerts. Candidates will analyze infrastructure performance, set maintenance windows, and design custom dashboards. They are also expected to interpret golden signals, evaluate alerts, use analytics, and perform backup or restore operations to maintain optimal system performance.
Topic 2
  • Configuration: This section of the exam measures the skills of DevOps Administrators and evaluates their ability to configure and optimize Instana operational settings. It involves setting up business process monitoring, configuring both cloud and serverless agents, and defining agent proxy parameters. Candidates will learn to implement various technologies and sensors, manage OpenTelemetry integrations, set up smart alerts, create service naming rules, and define custom SLIs and payloads for alert channels. Managing licenses and ensuring proper configuration of alerts and notifications are also key components of this domain.
Topic 3
  • Troubleshooting: This section of the exam measures the skills of System Support Engineers and focuses on resolving technical and operational issues in Instana. It includes configuring log levels, collecting logs for debugging, and identifying connectivity issues between agents and the backend. Candidates will troubleshoot installation failures, diagnose communication problems, and apply corrective measures to ensure consistent Instana performance and stability across environments.

IBM Instana Observability v1.0.277 Administrator - Professional Sample Questions (Q29-Q34):NEW QUESTION # 29
Which statement is true about webhook URL authentication?
Answer: D
Explanation:
According to IBM Instana's integration documentation, webhook notifications support Basic Authentication by embedding the username and password into the URL as part of the standard format (https://user:password@hostname/path). The exact extract from IBM states: "For webhooks requiring basic authentication, username and password must be specified by prepending these values to the webhook hostname in the URL." This approach is supported by most HTTP libraries and ensures ease of integration with third-party endpoints. Instana also allows other advanced authentication mechanisms for webhooks, but this is the documented approach for standard Basic Auth scenarios. Additional header configuration (B) is possible but not required for basic authentication, and option D is incorrect as Basic Auth is explicitly supported (and documented). Limiting to only the Authorization header (C) oversimplifies the supported authentication workflows.

NEW QUESTION # 30
Which protocol does an agent use to send the data to the backend?
Answer: B
Explanation:
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.

NEW QUESTION # 31
In Instana Standard Edition, which statement is true about the migration from a single-node deployment to a multi-node deployment?
Answer: C
Explanation:
IBM's deployment guidance notes a clear difference between demo and production-type installations. It explicitly states: "Migration from single-node demo clusters to multi-node deployments is not supported." Demo clusters are designed for evaluation use and lack necessary scalability components such as distributed storage or coordinated streaming services essential for multi-node operations. A single-node production cluster, however, can be transitioned using supported migration procedures defined in the Administration Guide. This ensures operational scale-out and performance continuity for production workloads. Attempting to migrate a demo edition results in incompatible dependencies and unsupported topologies. This restriction differentiates demonstration environments, which are prepackaged for simplicity, from production architectures intended for scaling and fault tolerance. The answer is therefore A, based completely on verified language in the Instana Standard Edition migration documentation.

NEW QUESTION # 32
By default, which rate limit is applied to Instana API calls for per hour usage?
Answer: D
Explanation:
Instana sets API rate limits to ensure fair resource usage and platform stability across accounts. According to the IBM Instana Observability documentation, "The default rate limit for the Instana REST API is 5,000 calls per hour per account." This policy is enforced automatically; when an account's API activity reaches the limit, further requests are temporarily blocked until the next hour begins. This guards against accidental overload as well as malicious consumption, and is fundamental for multi-tenant operation. Organizations may request increases for large-scale use cases, but 5,000 per hour is the standard value pre-configured for all accounts. Instana recommends that automation and integrations are engineered to respect this quota, using exponential backoff and batching if needed. Values such as 10,000, 6,000, or 1,000 are not defaults, and modifying them requires special support intervention.

NEW QUESTION # 33
What happens when multiple agent configuration files are created and put alongside the main configuration.yaml?
Answer: B
Explanation:
IBM Instana Observability's agent supports modularized configuration through multiple YAML configuration fragments within its configuration directory. As described in the documentation: "When multiple configuration files exist alongside the main configuration.yaml, the agent reads each in alphabetical order and applies configurations sequentially." This mechanism supports composable and layered configuration management, allowing base settings in configuration.yaml to be overridden or extended by secondary fragments. The key design principle is deterministic merge order-guaranteeing predictable configuration hierarchies across deployments. This method improves maintainability in large environments by facilitating separation of sensitive and technology-specific settings while maintaining a consistent merge process. IBM warns not to name multiple files with overlapping keys unless intentional overrides are desired. The merge is additive and case-sensitive, processed lexicographically, providing administrators both flexibility and traceability for troubleshooting and auditing. There is no error generated when multiple files are present; rather, Instana agent gracefully integrates them during initialization, a behavior that promotes advanced configuration modularity for complex deployments.
