• An enterprise architect is designing an Instana self-hosted deployment and needs to understand data storage responsibilities across backend components. Which backend component is primarily responsible for storing long-term infrastructure metrics data in the Instana platform?
• During Instana architecture planning, a solutions architect must document the data flow from monitoring agents to backend datastores for a compliance review. What is the primary role of Apache Kafka in the Instana backend architecture?
• A financial services company requires high availability for their Instana deployment with no single point of failure. When planning the Elasticsearch cluster for production, what is the minimum number of Elasticsearch nodes required to achieve a quorum-based fault-tolerant configuration?
• A platform engineering team is sizing a Cassandra cluster for an Instana self-hosted deployment monitoring 300 hosts. According to Instana sizing guidelines, which factor most directly determines the disk capacity required for the Cassandra cluster?
• An Instana administrator is documenting all backend architecture components for a security compliance audit and must explain each component's function. What is the primary function of Apache Zookeeper in the Instana backend infrastructure?
• A managed service provider wants to offer Instana-based monitoring to 10 enterprise customers. Each customer requires complete data isolation, a separate user directory, and independent RBAC configurations. Which deployment architecture should the Instana architect recommend?
• A DevOps team is planning capacity for their Instana self-hosted deployment and needs to understand trace data storage. In modern Instana deployments (version 1.0.277+), what is the default trace data retention period and which backend component serves as the primary trace data store?
• An operations team is sizing long-term storage for an Instana deployment and must understand how metric data is stored over time. Which statement correctly describes how Instana handles infrastructure metric granularity and retention?
• An enterprise with 2,500 hosts spread across 8 data centers plans to deploy Instana agents. The architect is concerned about network bandwidth consumption and excessive direct connections to the central Instana backend over WAN links. Which deployment pattern should be incorporated into the agent deployment plan?
• An Instana administrator is planning a major version upgrade for their self-hosted deployment. To minimize compatibility issues and service disruption, what is the recommended sequence for upgrading Instana components?

• A company runs Instana agents across three geographic regions: US-East, EU-West, and APAC. The operations team needs to scope infrastructure dashboards and alert policies by region and ensure logical grouping of monitored infrastructure. How should the agent deployment plan address this requirement?
• A company is migrating its monitoring platform from Dynatrace to Instana across 800 production hosts. The operations team has a hard requirement that there must be no monitoring blackout during the migration period. Which migration planning approach best ensures continuous observability throughout the transition?
• A procurement team is evaluating Instana licensing costs for an environment containing 300 physical servers, 400 virtual machines, and 2,000 Docker containers distributed across those VMs. How are Instana host unit entitlements correctly calculated for this environment?
• During an architecture planning review, a stakeholder questions why ClickHouse is included in the Instana backend stack when Cassandra already handles data storage. What is the primary purpose of ClickHouse in the Instana backend?
• An architect is performing initial capacity planning for a new Instana self-hosted deployment that will monitor 1,000 hosts at peak load. Which resource type most commonly becomes the primary performance bottleneck and should be provisioned most generously in the Cassandra cluster at this scale?
