A component relationship diagram can be used to establish impact analysis.

A.
True

B.
False

Explanation:

In an upstream relationship, a logical object or component has a dependency on other items inthe
solution. For example, a service running on an application server requires an Active Directory user
accountto be authenticated. The application service must be started after the Active Directory
service. Therefore, theapplication server has an upstream relationship with the Active Directory
service.
In an downstream relationship, a logical object or component does not have a dependency on
other items inthe solution. For example, say that a multisite web server crashes. The web tier
hosting multiple websites willcrash; however, the downstream objects such as the database server
will continue to function. Backendprocesses that are dependent on the downstream objects from
the web servers can continue to function.
