1. Question 1

   For which event type does Instana create an alert because end users are impacted?

   AChanges
   

   BIncident
   

   CIssues
   

   DMonitoring issues
   

   Correct answer: B

   Based on IBM Instana documentation review, Incidents are the event type that triggers alerts when end users are impacted. The official IBM documentation states: 'An incident helps you to understand situations impacting your edge services and critical infrastructure... Incidents are created as soon as Instana detects either a key performance indication (KPI) is breached on an edge service, or a critical infrastructure issue.' However, the documentation also clarifies: 'An issue is an event that is triggered if something out of the ordinary happens... An issue by itself does not trigger an alert, Instana simply notes that it happened. Should the service to where this system is connected behave badly, this issue is part of the incident.' Critical issues can trigger alerts and may impact end users, but Incidents are specifically designed to represent situations where end-user-facing services (edge services) are impacted. The answer is B. Incident as the primary event type for end-user impact alerts.

   
   

2. Question 2

   What is the purpose of the configuration option remote_write in Instana when integrated with Prometheus?

   ATo write data to Prometheus
   

   BTo display metrics as either a Prometheus Entity or part of the Process Custom Metrics
   

   CTo configure remote access to Instana
   

   DTo display metrics as only a Prometheus Entity
   

   Correct answer: B

   IBM Instana integrates natively with Prometheus to unify metric ingestion without disrupting existing telemetry setups. The configuration parameter remote_write enables this linkage. The official documentation states: 'The remote_write configuration enables Prometheus to send data to Instana, where those metrics are displayed either as Prometheus entities or merged into process custom metrics.' Instead of storing them only within Prometheus, Instana pulls remote_write relay feeds to create comprehensive, unified metrics views in its dashboard. This approach avoids duplicate monitoring systems and allows alerting across both Prometheus and Instana data seamlessly. The parameter does not configure outbound writing by Instana back into Prometheus---data always flows from Prometheus to Instana in this architecture. This integration respects Prometheus scraping principles yet centralizes analysis within Instana, achieving correlation between imported numerical time-series values and native metrics at the application or process layer.

   
   

3. Question 3

   At which level can AWS agent polling intervals for CloudWatch API be configured?

   AResource group
   

   BRegion
   

   CAccount
   

   DService
   

   Correct answer: B

   AWS monitoring through Instana involves integration with the CloudWatch API to retrieve platform and service metrics. The official IBM Instana Observability documentation affirms that polling intervals for CloudWatch can be set at the Region level. This means an administrator configures how frequently Instana's agent queries CloudWatch within each specified region independently. This level of granularity provides flexibility: for example, mission-critical regions may be monitored more frequently, while others are polled less often to reduce API costs or remain within AWS rate limits. The documentation specifies: 'Instana Agents for AWS can be configured with a polling interval for CloudWatch that is set per Region to customize granularity and resource consumption.' Polling cannot be set at the account, resource group, or individual service level in default configuration. Instana's region-based polling helps balance data accuracy and overhead, especially in global or multi-region deployments. If needed, changes are applied through YAML configuration or UI during AWS agent integration setup.

   
   

4. Question 4

   Which protocol does an agent use to send the data to the backend?

   AHTTPS
   

   BFTP
   

   CSSH
   

   DNFS
   

   Correct answer: A

   IBM Instana agents use HTTPS, the industry standard secure protocol, to transmit telemetry data to Instana's backend servers or clusters. Instana documentation says: 'All agent-to-backend traffic is encrypted and transmitted via HTTPS, meeting data confidentiality and compliance requirements.' The use of HTTPS prevents unauthorized data interception by using strong TLS encryption on every packet exchanged between agent and backend, regardless of whether the deployment is on-premises or SaaS. FTP, SSH, and NFS are protocols for file transfer, system access, or storage mounting but are never used for telemetry transmission in Instana's architecture. Secure HTTP is essential for privacy by design, is policy-enforced, and supports audit-friendly observability in all supported Instana versions per IBM standards.

   
   

5. Question 5

   For Instana Standard Edition, in which file should the salesKey be updated?

   Aconfig.yaml
   

   Blicense.json
   

   Cdownload.pl
   

   DGui.api
   

   Correct answer: B

   Licensing in Instana is controlled by a key called 'salesKey,' which must be placed in the license.json file for Standard Edition. Per IBM Instana Observability documentation, 'The salesKey is part of the license.json file, which must be updated to activate the Instana Standard Edition license.' This file is checked at startup and authorizes agent/server deployment, binding entitlement and features to the account. Instana's licensing model relies on proper key management within license.json for compliance and support tracking. The config.yaml file manages agent technical configuration, not licensing. Download.pl and gui.api files are not associated with salesKey or licensing. Any update to the license must be done within license.json and validated by Instana's backend for activation completeness---this procedure is outlined step-by-step in the installation and onboarding guides.
