The Infrastructure map in IBM Instana provides a dynamic and interactive visualization of all monitored systems. Its primary purpose is to offer a high-level overview of the entire infrastructure landscape. A key organizational feature of this map is the grouping of systems by availability zones, which helps in understanding the physical or logical layout and health of the infrastructure at a glance. Users can interact with the map by zooming, panning, and selecting specific hosts or zones to investigate further details and metrics.

A. This is partially correct but incomplete. The map does show relations, but its defining feature is the overview of all systems grouped by zones, which this option omits.

B. The map is dynamic and interactive, reflecting real-time data. A static image would not serve the purpose of live infrastructure monitoring, making this option incorrect.

D. This describes the Application Perspective or Dependency Map, which visualizes the relationships and calls between services, not the underlying infrastructure hosts and zones.

1. IBM Instana Observability Documentation, "Visualizing infrastructure": "The Infrastructure map provides an overview of all monitored systems. It helps you to understand the layout of your system and provides a high-level overview of your infrastructure... The map is organized by zones... The map is interactive. You can zoom, pan, and click on individual systems to see more details." (IBM Documentation, Visualizing infrastructure, Infrastructure map section).
