IBM C1000-189 Exam Syllabus Topics:
TopicDetails
Topic 1
  • 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.
Topic 2
  • Integration: This section of the exam measures the skills of Integration Engineers and assesses their proficiency in connecting Instana with external monitoring and automation tools. Candidates must demonstrate knowledge of integrating agent-based systems such as Omegamon, ITM, and ITCAM, as well as external platforms like Prometheus and Grafana. The section also includes configuring alert channels, automation actions, and utilizing the Instana REST API to support customized workflows and data visibility.
Topic 3
  • Security and Compliance: This section of the exam measures the skills of IT Security Analysts and focuses on the data protection and compliance aspects of Instana deployment. Candidates must describe and implement data retention policies, plan for regulatory compliance, secure APIs, manage user access, and interpret audit logs. The goal is to ensure secure system configurations that align with organizational and regulatory standards.
Topic 4
  • 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.

IBM Instana Observability v1.0.277 Administrator - Professional Sample Questions (Q10-Q15):NEW QUESTION # 10
Which type of custom resource supports the retention policy settings in the Custom Edition?
  • A. CoreSpec
  • B. ConfigYaml
  • C. UnitProp
  • D. StorageConf
Answer: A
Explanation:
According to the official IBM Instana Observability documentation (v1.0.304), retention policy settings in Custom Edition are NOT configured in a custom resource called "StorageConf." Instead, they are configured as properties within the CoreSpec of the Core custom resource. The documentation explicitly states: "Overwriting the default retention settings is optional and should only be done consciously. These retention setting values are configured as properties in the CoreSpec." The actual configuration looks like this:
text
kind: Core
metadata:
name: instana-core
namespace: instana-core
spec:
properties:
- name: retention.metrics.rollup5
value: "86400"
- name: config.appdata.shortterm.retention.days
value: "7"
- name: config.synthetics.retention.days
value: "60"
The retention policies for infrastructure metrics, application data, and synthetic monitoring are all configured as properties within the Core spec, not in a separate "StorageConf" custom resource. "StorageConf" refers to storage configurations for raw spans (S3, GCS, Azure), not retention policies.

NEW QUESTION # 11
What is required for automatic backend correlation to work given that the EUM agent has been properly set up?
  • A. Exposure of the backend trace id
  • B. Matching application perspective
  • C. The Instana SDK
  • D. Valid HTTPS connection
Answer: A
Explanation:
To successfully achieve automatic correlation between frontend and backend traces, Instana requires backend services to expose a trace identity. The IBM Instana EUM and tracing correlation section confirms: "Automatic backend correlation requires exposure and propagation of the backend trace ID to connect user interaction traces with backend processing traces." When the EUM agent operates in browsers or mobile interfaces, it injects headers containing Trace and Span IDs into subsequent backend HTTP requests. Backend instrumentation must read and propagate these identifiers through service calls so Instana can unify them into a single end-to-end transaction trace. Proper correlation connects a user's session-to-service journey across web, application, and infrastructure layers, a fundamental aspect of Instana's distributed tracing model. Lacking backend trace ID propagation causes separated traces that cannot be linked, even if HTTPS, SDK, or application perspectives are configured correctly. This mechanism remains fully verified in the IBM Instana Observability Tracing Integration Guide.

NEW QUESTION # 12
Which statement is true about webhook URL authentication?
  • A. Basic authentication is not supported due to security constraints.
  • B. Prepend username and password to the hostname URL for authentication.
  • C. Only Authorization HTTP request header is supported.
  • D. Specification of additional Headers is not supported for authentication.
Answer: B
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 # 13
Which two methods can Instana administrators use to create an API token?
  • A. JSON Web tokens
  • B. Sensor-specific API token
  • C. Unit-specific API tokens
  • D. Personal API tokens
  • E. Team API token
Answer: D,E
Explanation:
IBM Instana supports two primary methods for creating API tokens necessary for secure automation and integration: Team API tokens and Personal API tokens. The official documentation states: "API tokens for REST API access can be generated either on a per-user (personal) basis, or at the team level for shared automation use." Personal tokens are created from the user profile menu and scoped to an individual's permissions, supporting traceability and revocation. Team tokens are created under team or group settings and represent organizational integrations or CI/CD pipeline automation. JSON Web Tokens (A) are an industry token standard but not a creation flow in Instana. Unit- or Sensor-specific tokens are not supported (C, D); all automation integrations must use Personal or Team tokens, which are easily managed and rotated via the web UI for improved security hygiene.

NEW QUESTION # 14
When are issues or incidents triggered in Instana while using .Net sensor?
  • A. During regular maintenance
  • B. When a sensor goes offline
  • C. When a user logs in
  • D. Based on failing health signatures or custom metric thresholds
Answer: D
Explanation:
Instana triggers Issues and Incidents based on dynamic health signatures and custom metric thresholds established for .NET applications. The official documentation clarifies: "Issues are generated automatically when health signatures fail or when custom metric thresholds are breached for .NET sensors, indicating performance or reliability degradation." This includes transaction latency, error rates, resource exhaustion, or process failure detection. Health signatures are built-in, algorithmic checks using expected baselines and historical data. Custom thresholds may be established by users for business-specific metrics (e.g., request time or throughput), further enriching early warning detection. Offline sensors or regular maintenance only lead to downtime or muted alerts, not issues/incidents. User logins reflect authentication flow monitoring and do not prompt system-wide issues in Instana's event model unless login failure ties to health impacts.
