Sample Practice Questions

Try these 10 sample questions from the IBM Instana Observability v1.0.277 Administrator - Professional practice bank. Each includes the answer and explanation. Continue with the interactive practice above to review the full question set.

1. 1An organization requires IBM to manage the Instana backend rather than installing it in its own infrastructure. Which deployment option meets this requirement?

   1. A.Instana SaaSCorrect answer: A
   2. B.Self-hosted Standard Edition
   3. C.Self-hosted Custom Edition
   4. D.Self-hosted Classic Edition

   Explanation: IBM describes the deployment as "SaaS: Managed by IBM." The self-hosted editions require a backend in the organization’s own environment.

2. 2When manually downloading an Instana static or dynamic agent package using IBM's documented authenticated download endpoint, which password should be supplied?

   1. A.The Instana agent keyCorrect answer: A
   2. B.The Instana API token
   3. C.The operating system password
   4. D.The Instana UI user password

   Explanation: IBM gives the download credentials as "Password: <agent_key>". This is the agent key used for the package endpoint, not a UI or operating system login.

3. 3On a Linux Instana host agent installed under /opt/instana/agent, which file contains its YAML sensor configuration?

   1. A./opt/instana/agent/etc/org.ops4j.pax.logging.cfg
   2. B./opt/instana/agent/data/log/agent.log
   3. C./opt/instana/agent/etc/instana/configuration.yamlCorrect answer: C
   4. D./etc/systemd/system/instana-agent.service.d/20-resource_limits.conf

   Explanation: IBM lists the agent configuration file as "<instana-agent-dir>/etc/instana/configuration.yaml". With the stated default directory /opt/instana/agent, the full path is /opt/instana/agent/etc/instana/configuration.yaml.

4. 4What should an administrator provide to authenticate an Instana backend API request and control its permitted operations?

   1. A.An agent key rather than an API token
   2. B.An API token without the permission needed for the operation
   3. C.A valid API token with the required permissionsCorrect answer: C
   4. D.An expired API token with the required permissions

   Explanation: IBM says: "To use Instana API, An API token is required." It also instructs administrators to set token permissions according to the required API use.

5. 5When calling the Instana REST API, which base URL should be combined with the API endpoint path?

   1. A.The host agent's backend acceptor endpoint
   2. B.The Prometheus exporter's scrape endpoint
   3. C.The Grafana server's dashboard URL
   4. D.The tenant unit's Instana UI base URLCorrect answer: D

   Explanation: IBM says the API base is the "Tenant unit's base URL, which is also the URL used to access the Instana user interface." The API endpoint path is appended to that base rather than to a monitored host or Grafana URL.

6. 6A team wants IBM to deploy and maintain its Synthetic PoP. What choice matches the 2024 Instana-hosted offering?

   1. A.Managed PoP, deployed and maintained by IBMCorrect answer: A
   2. B.Managed PoP, deployed and maintained by the customer
   3. C.Private PoP, deployed and maintained by IBM
   4. D.Private PoP, deployed and maintained by the customer

   Explanation: IBM says the "Instana-hosted Synthetic PoP is available to relieve customers from the effort and details of PoP deployment and maintenance." Its deployment instructions identify the Managed type; Private is the self-hosted option.

7. 7In IBM's host agent management interface example, how long does an agent log-level change made through the interface remain in effect?

   1. A.5 minutesCorrect answer: A
   2. B.1 minute
   3. C.15 minutes
   4. D.60 minutes

   Explanation: IBM states that changing the log level in that interface "takes effect for only 5 minutes" before it switches back to INFO.

8. 8Which tool does IBM identify for automating cluster deployment and data store installation in most self-hosted Standard Edition deployments?

   1. A.kubectl
   2. B.stanctlCorrect answer: B
   3. C.Helm
   4. D.Terraform

   Explanation: IBM states: "For most deployments, the stanctl tool automates cluster deployment, data store installation, updates and more." The other tools do not answer which tool IBM identifies for this Standard Edition role.

9. 9An administrator deploys an Instana host agent on the infrastructure hosting Instana itself for self-monitoring. Which agent mode does IBM specify for this deployment?

   1. A.APM mode
   2. B.Infrastructure modeCorrect answer: B
   3. C.Disabled mode
   4. D.AWS mode

   Explanation: IBM specifies that any such agent "must be deployed in Infrastructure mode." The condition is self-monitoring the infrastructure on which Instana is installed.

10. 10An administrator adds the documented Docker log collection configuration to the Instana agent configuration file. What does IBM instruct the administrator to do to refresh that change?

    1. A.Restart the Docker service on each monitored host
    2. B.Restart the monitored Docker containers
    3. C.Restart the Instana backend service
    4. D.Restart the Instana Agent serviceCorrect answer: D

    Explanation: In the Docker runtime logs procedure, IBM says: "Restart the Instana Agent service to refresh the changes." The procedure applies to the agent configuration change.
