Question 9

Refer to the exhibit.

This graph represents the number of requests waiting for a response across various tiers. With load being generated at a constantly increasing rate, which tier is the bottleneck and why?

Options:

A.

The Web tier is the bottleneck because it has the most open requests waiting for a response.

B.

The DB tier is the bottleneck because it is the lowest tier that is clearly not handling requests in time.

C.

The App tier is the bottleneck because it is the first tier not handling the same number of requests as the tier above it.

The Web tier is the bottleneck because at an Offered Load of 300, there are still 50 requests waiting from the Web tier, and it never recovers. The lower tiers do not get the requests passed to them because the Web tier is not processing fast enough.

E.

The App tier is the bottleneck because the DB tier is handling everything the App tier sends it.

It is best to instrument at the application tier, since it sits between the web and database tiers.
