• A DevOps engineer needs to deploy the Instana host agent on a bare-metal Linux server running RHEL 8. The organization requires all software installations to use the system package manager (yum/dnf). The server has internet access. Which installation method should the engineer use?
• An SRE team deployed the Instana agent as a DaemonSet on their Kubernetes cluster. All agent pods are running and reporting healthy, but pods in the newly created 'billing-service' namespace are not appearing in Instana. What is the most likely cause?
• After deploying the Instana host agent, an administrator sees the agent listed as OFFLINE in the Instana backend. The agent logs show repeated 'Connection refused' errors when attempting to reach the Instana server. What should the administrator investigate first?
• A team lead wants to create an Instana dashboard showing error rate and throughput for three microservices. The dashboard must be visible to all team members but editable only by team leads. What is the correct approach?
• An operations team wants to alert on unusual error rate spikes for any service in their e-commerce application without manually setting thresholds for each of the 40 services individually. Which Instana feature best addresses this requirement?
• A junior SRE created an Instana alert channel configured with the PagerDuty integration, but no incidents are being created in PagerDuty even though high-error-rate alerts are firing in Instana. What is the most likely missing configuration step?
• A product team wants to define a 99.5% availability SLO for their checkout API using a 30-day rolling window in Instana. What must be configured in Instana BEFORE the SLO can be created?
• An SRE team has configured a 99.9% availability SLO on a 28-day rolling window. After two weeks, the Instana SLO dashboard reports the error budget is at 15% remaining. What does this indicate?
• An Instana operator sees multiple simultaneously firing events for high CPU, high memory, and slow response time on the same host in the Events view, but no incident has been created. What is the most likely reason?
• A team deployed a new version of their order-processing service at 14:32. Response times spiked sharply starting at 14:35. Which Instana capability most effectively helps the team correlate the deployment with the performance degradation during investigation?
• A performance engineer needs to find all HTTP calls to the /api/checkout endpoint that took longer than 2 seconds AND returned a 5xx HTTP status code across all services in the last 6 hours. Which Instana capability is best suited for this investigation?
• A company's platform has 50+ microservices. The checkout team wants a focused Instana view showing only the services, calls, and metrics relevant to the checkout flow, without seeing unrelated infrastructure or other teams' services. What should they configure?
• An SRE is investigating latency on the product catalog service. In the Instana Service Map for their Application Perspective, three downstream dependencies are shown with red node indicators. What do these red indicators most likely represent?
• An enterprise using Instana across 12 teams wants to implement tagging so that all monitoring data can be filtered by business unit, environment (prod/staging/dev), and team ownership. Where are custom tags most effectively applied to achieve broad filtering capability?
• A team wants to deploy the Instana host agent as a Docker container to monitor other containers and the underlying host. Which set of volume mounts is required to enable complete host and container monitoring?
• An administrator manages hosts across three data centers: US-East, EU-West, and APAC. They want these locations to appear as distinct groupings in the Instana Infrastructure view. What is the recommended way to configure this organizational structure?
• A service owner needs to present quarterly SLO compliance data to management. The SLO is defined in Instana with a 99.5% target on a 30-day rolling window. What limitation should the service owner be aware of when using Instana's built-in SLO dashboard for this purpose?
• A developer is using Instana Unbounded Analytics to find all MongoDB calls from the 'inventory-service' that took longer than 500ms in the past 24 hours. Which approach should they use?
• After installing the Instana host agent on a Linux server running Apache Tomcat, a junior administrator can see host-level CPU and memory metrics in Instana, but Tomcat-specific metrics (heap usage, thread count, request rate) are not appearing. What is the most likely explanation?
• An operations team's Smart Alert for sudden error rate increases is generating excessive false positives for low-traffic services where a single failed request causes a large percentage spike. How should they tune the Smart Alert to reduce these false positives?
• An Instana operator sees both 'Issues' and 'Incidents' in the Events view and asks a colleague to explain the difference. Which explanation is correct?
• A corporation routes all outbound internet traffic through a corporate HTTP proxy. The Instana host agent is installed but cannot reach the Instana backend. Other tools on the host connect successfully through the proxy. Where should the proxy be configured for the Instana agent?
• A team wants to add a widget to their custom Instana dashboard showing the P99 latency trend for their API gateway service over the last 7 days. Which widget type and data source should they configure?
• An SRE team wants the Instana Kubernetes agent to automatically monitor all pods in current and future namespaces without requiring agent reconfiguration each time a new namespace is created. How should the agent be configured?
• A development team has tagged all services they own with the label 'team:payments' using Instana tags. They want their Application Perspective to dynamically include only services carrying this tag, including services added in the future. How should they configure the Application Perspective scope?
