IBM Certified Instana Observability v1.0.277 Administrator - Professional · 47 questions

• An administrator is deploying Instana agents across a fleet of RHEL 8 servers. The team wants agents to receive automatic updates whenever Instana releases new sensor versions. Which package should the administrator install?
• A DevOps engineer is installing the Instana agent on Ubuntu 22.04 LTS. During repository configuration, they must ensure the APT package manager can authenticate packages from the Instana repository. What must be added to trust the Instana APT repository?
• After installing the Instana host agent on Windows Server 2022, the administrator notices the agent cannot collect several system-level performance metrics. The agent service started without errors. What is the most likely cause?
• An administrator needs to deploy the Instana host agent on an IBM AIX 7.2 server to monitor a critical financial application. The administrator is experienced with Linux RPM installations but has not set up Instana on AIX before. Which installation approach is supported for AIX?
• A Kubernetes administrator is deploying the Instana agent as a DaemonSet using the standard Instana deployment manifests. A Kubernetes Secret named instana-agent-secret has been created containing the agent key, but agent pods fail to authenticate with the backend. The DaemonSet references the Secret correctly by name. What is the expected data field name within the Secret for the agent key?
• A platform engineer is deploying the Instana Kubernetes agent using the official Instana Helm chart. The deployment requires a corporate proxy configuration and a non-default on-premises backend endpoint. Which Helm command syntax correctly applies a custom values file to override chart defaults?
• An administrator has deployed the Instana Operator on a Kubernetes cluster and created an InstanaAgent custom resource. Agent pods start but immediately fail to connect to the on-premises Instana backend. The CR spec has the correct agent key configured. Which CR spec field must be set to specify the Instana backend hostname?
• When deploying the Instana agent DaemonSet on Red Hat OpenShift 4.x, all agent pods immediately fail with a forbidden error citing a security context violation. The DaemonSet requires host-level access to collect infrastructure metrics. What is the correct remediation?
• An administrator running the Instana agent as a Docker container reports that no host processes appear in the Instana UI even though the container is running and all other infrastructure metrics are visible. Which Docker run flag must be added to enable host process visibility?
• An organization plans to deploy Instana Standard Edition on-premises to monitor a 500-host production environment. The infrastructure team must size the backend server correctly before procurement. Which hardware configuration represents an appropriate baseline for this deployment scale?
• An enterprise deploying Instana Custom Edition wants to separate data storage from processing components to enable independent scaling. Which backend components can be placed on dedicated servers separate from the main processing nodes in a Custom Edition deployment?
• A system administrator is evaluating the resource impact of deploying the Instana host agent on latency-sensitive production servers running financial transaction processing. The server team requests the expected CPU overhead of the Instana agent under normal operation. What is the correct characterization?
• An administrator is preparing to install the Instana host agent on a server where a Java 8 runtime is required by the deployed application. The team is concerned that Instana may conflict with the existing Java environment or require a version upgrade. How does the Instana agent handle its Java runtime dependency?
• A network engineer is creating firewall rules to allow Instana host agents in an isolated production network segment to communicate with an on-premises Instana backend server. Which TCP port must be permitted for outbound traffic from agent hosts to the backend?
• In an Instana Custom Edition deployment, the Cassandra data store cluster runs on a dedicated network segment separate from the Instana backend processing nodes. The network team must define firewall rules between these segments to enable backend operation. Which rule is required?
• An Instana host agent deployed in a corporate network cannot reach the on-premises backend because all outbound HTTPS traffic must pass through an authenticated proxy server. The agent is installed on Linux. Where must the proxy configuration be specified to ensure the agent routes its traffic correctly?
• An organization deploys Instana with an on-premises backend whose TLS certificate is signed by an internal corporate Certificate Authority not trusted by default. Instana agents are failing to connect with a certificate verification error. Network connectivity to the backend is confirmed. What is the correct remediation?
• An operations team wants Instana agents to automatically update to the latest available version but only within an approved maintenance window from 2:00 AM to 4:00 AM local time. They want to avoid manually modifying files on individual servers. What is the recommended approach to configure this schedule?
• A change management team requires that production Instana agents remain on the currently approved version and must not auto-update until a new version passes UAT review. Agents are installed as instana-agent-dynamic across 200 Linux servers. What is the most operationally efficient centralized approach to enforce this?
• An administrator installs the Instana host agent on a new Linux server. After 15 minutes the host does not appear in the Instana UI. The agent service is confirmed running, network connectivity to the backend on port 443 is verified, and the configuration.yaml shows the correct backend host and port. What is the most likely reason the agent is absent from the UI?
• An infrastructure team is preparing to upgrade an on-premises Instana Standard Edition backend from version 275 to version 277. The Instana administrator must identify the most critical step to complete before executing the Instana update command on the backend server. What must be done first?
