IBM Instana Observability v1.0.277 Administrator - Professional Sample Questions (Q22-Q27):NEW QUESTION # 22
How can the configuration parameters be changed when installing Synthetics via Helm?
  • A. By modifying the default Helm chart directly
  • B. By passing values through environment variables only
  • C. By specifying values with the --set flag or providing a YAML file with the -f flag
  • D. By using the --config flag to specify a configuration file
Answer: C
Explanation:
IBM Instana Observability supports deploying and managing components like Synthetic PoPs and monitoring collectors through Helm charts in Kubernetes environments. The official documentation explicitly states: "To customize the configuration of Instana Synthetics deployments using Helm, specify values either directly with the --set flag or via a configuration file passed with the -f flag during the Helm install or upgrade command." This approach aligns with Kubernetes best practices by maintaining immutable packaged charts while permitting flexible, environment-specific configurations through overrides. The --set parameter allows single-line value changes from the command line (for example, setting API keys or namespace values), whereas using a YAML file provides structure for multi-parameter updates and offers version control capability. IBM warns against manual edits in default Helm charts or direct environment-based configurations as these can be overwritten during automation or chart upgrades. Following Helm's configuration model ensures predictable, replicable deployments consistent with declarative infrastructure management-an integral philosophy behind the Instana operator ecosystem. The combination of -f and --set enables a scalable and consistent way to customize Synthetics installation across clusters.

NEW QUESTION # 23
Which HTTP header is automatically collected?
  • A. Instana-id
  • B. x-client-id
  • C. X-Instana-Service
  • D. Instana-probe
Answer: C
Explanation:
Instana traces and analyzes every request. Services and endpoints are automatically discovered, and relationships between services, endpoints, and your infrastructure are autocorrelated and stored in our Dynamic Graph.
Based on the data that is collected from tracers and sensors, KPIs are calculated for calls, latency, and erroneous calls. KPIs help you discover the health of every individual service and then the health of your entire infrastructure.
Services are a part of application monitoring and provide a logical view of your system. Services are derived from infrastructure entities such as hosts, containers, and processes. Incoming calls are correlated to infrastructure entities and enriched with infrastructure data; for example, the Kubernetes pod label or SpringBoot application name. After this infrastructure-linking processing step, a service mapping step maps the enriched calls to generate a service name per call based on a set of rules. Instana comes with an extensive set of predefined rules to generate the best possible service name for you automatically. To fine-tune the service mapping, you can create your own custom rules, see customize service mapping.

NEW QUESTION # 24
Which two steps are performed in preparation for migrating from a self-hosted single-node deployment to a multi-node deployment of Instana?
  • A. Delete the disks from old host and move them to new host.
  • B. Start the self-hosted Standard Edition on the current host.
  • C. On all the three hosts, configure private IP addresses.
  • D. On the two new hosts, make sure to check the Kernel parameters.
  • E. On all the three nodes, configure Docker.
Answer: C,D
Explanation:
IBM's migration process for Instana specifies steps requisite for a successful transition from single-node to multi-node deployment. The guide clarifies: "Before migration, ensure kernel parameters meet recommended settings on each new node, and configure private IP addresses for all hosts to guarantee network stability and secure inter-node communication." Kernel parameter adjustment (C) involves tuning system limits and TCP behavior for high-availability performance. Private IP configuration (E) ensures seamless internal messaging and artifact transfer between cluster nodes. Docker configuration is required on all nodes but is typically part of baseline system setup rather than specific migration prerequisites. Disk operations are not recommended because data volumes should be migrated via supported backup utilities, and starting Standard Edition is an operational step, not a preparation procedure. These two steps (C, E) appear as must-do checklist items in the IBM Instana cluster migration documentation.

NEW QUESTION # 25
Which statement accurately describes the use of the agent key?
  • A. It is not included in the purchase email and must be obtained separately.
  • B. It is used for both downloading Instana artifacts and deploying an instance.
  • C. It is required only for downloading the license.
  • D. It is used only for deploying an instance.
Answer: B
Explanation:
The IBM Instana Observability product architecture uses a security credential called an agent key for authentication and authorization in both installation and deployment operations. The documentation explicitly affirms: "The agent key must be used for downloading Instana installation artifacts from IBM repositories as well as for deploying agents to connect to the backend." This binding ensures entitlement enforcement and integrity of data transfer. The key, distributed through official IBM entitlement channels or purchase confirmation emails, validates the customer's licensed environment. During deployment, the same key is included in configuration files or environment variables so that each agent securely authenticates to its assigned backend instance. This unified mechanism simplifies lifecycle management while maintaining strong license controls. The key is never generated manually nor limited to licensing download alone-its dual purpose makes it critical in both provisioning and operations stages.

NEW QUESTION # 26
What is Instana's custom built software that is designed to monitor a specified technology?
  • A. Sensor
  • B. Profiling
  • C. Service
  • D. Tracer
Answer: A
Explanation:
Instana uses Sensors as specialized software components embedded within its agents to monitor and extract telemetry from various supported technologies. The verified documentation states: "Sensors are built-in modules that detect, identify, and monitor specific technologies such as databases, servers, run-times, and messaging systems." These components ensure that the agent collects targeted metrics, events, and traces optimized for individual stacks like MySQL, Kafka, or Java. When deployed, the Instana agent automatically discovers technologies running in the environment and loads corresponding Sensors dynamically, requiring minimal user configuration. Tracers handle transaction propagation, Profiling covers code-level performance, and Service is a higher abstraction in application topology-not individual monitoring logic. The Sensor concept remains core to Instana's automatic discovery and observability architecture as validated in IBM's architectural reference sections.
