Field note / 22 April 2011
Exam 70 667 notes, part three: service applications
Service applications are easier to remember when they are understood as boundaries and dependencies rather than a list of names.
The middle of a study plan is where the material becomes a list of components. Service applications are a common example. There are many names, several dependencies and a set of proxy relationships that are easy to mix up under pressure.
A better approach is to group them by the problem they solve: identity, search, content, business data and shared services. Then ask what each one needs from the farm and what other services depend on it.
Draw the dependency map
For each service application, record the databases, accounts and endpoints it uses. Note where a proxy is required for a web application to consume it. A diagram with arrows is more useful than a memorised list because it explains why one missing piece can break several features.
Practise creating a small service in a lab, then break one dependency deliberately and observe the error. The recovery path is often more memorable than the happy path, and it maps better to the scenario questions in an exam.
The short list
Checks worth running
- Group services by purpose and dependency.
- Draw the proxy relationship between web applications and services.
- Practise one recovery after deliberately removing a dependency.
The exam rewards a model that can be reasoned with. If you can explain what breaks when a dependency disappears, the names become part of a system rather than a list.
