Explanation:

Using the topology view you can quickly see the components that comprise your cluster database environment, such as database instances, listeners, Oracle ASM
instances, hosts, and interfaces.
Note: Enterprise Manager provides a Topology Viewer which is a graphical representation of routing relationships across targets, components and elements. You
can easily determine how requests are routed across components. For example, you can see how requests are routed from Oracle Web Cache, to Oracle HTTP
Server, to a Managed Server, to a data source.
The Topology Viewer allows you to view the relationships between components, nodes, or objects within different Oracle applications.
