IBM Instana Observability v1.0.277 Administrator - Professional Sample Questions (Q26-Q31):NEW QUESTION # 26
Which statement accurately describes the use of the agent key?
  • A. It is required only for downloading the license.
  • B. It is used for both downloading Instana artifacts and deploying an instance.
  • C. It is used only for deploying an instance.
  • D. It is not included in the purchase email and must be obtained separately.
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 # 27
Which two steps are performed in preparation for migrating from a self-hosted single-node deployment to a multi-node deployment of Instana?
  • A. On the two new hosts, make sure to check the Kernel parameters.
  • B. On all the three nodes, configure Docker.
  • C. Start the self-hosted Standard Edition on the current host.
  • D. Delete the disks from old host and move them to new host.
  • E. On all the three hosts, configure private IP addresses.
Answer: A,E
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 # 28
Which statement is true about webhook URL authentication?
  • A. Prepend username and password to the hostname URL for authentication.
  • B. Basic authentication is not supported due to security constraints.
  • C. Specification of additional Headers is not supported for authentication.
  • D. Only Authorization HTTP request header is supported.
Answer: A
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 # 29
When installing the Instana host agent on Kubernetes, which option is valid?
  • A. RPM
  • B. Binary
  • C. Operator
  • D. Homebrew
Answer: C
Explanation:
The Instana Operator is the officially recommended and supported method for deploying the Instana host agent on Kubernetes clusters. The IBM Instana Observability documentation states, "The recommended method to install the Instana agent on Kubernetes clusters is via the Instana Operator, which uses Custom Resources to simplify lifecycle management." The Operator pattern in Kubernetes automates not just installation, but also upgrades, configuration, and management of agents across the entire cluster. This ensures security and reliability because the Operator reacts to cluster changes and can self-heal agent deployments. Other install options such as Homebrew, direct binary, or RPM are for traditional VM or bare-metal hosts-not for orchestrated container environments like Kubernetes. Only with the Operator does Instana support automated scaling, configuration through CRDs, and native Kubernetes best practices. Helm charts are also often involved in configuring the Operator, further streamlining agents' deployment in public, private, or hybrid cloud clusters.

NEW QUESTION # 30
What does the stanctl cluster backup do?
  • A. Backup data of a remote Instana host
  • B. Create an archive file in the current directory
  • C. Create a snapshot of the disks
  • D. Prepare the current directory for the backup procedure
Answer: B
Explanation:
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.
