Maybe I should generalize my question a little bit?
Reading through groupstudy posts on task interpretation there seems to
be two schools of thought:
School #1:
Do exactly what the task states, nothing more.
School #2:
Look for the implicit requirements of the task and solve for those as well.
What school of thought do those who have passed usually follow?
Here's another example:
Task states to guarantee 25% of bandwidth to web traffic going to server
with IP 99.99.99.99.
Lets say you configure your QOS policy perfectly, but your network doesn't
have reachablilty to that IP (you couldn't get routing working properly for
example).
Considering your hosts cannot reach the web server you cannot reserve
anything, so would you lost points for something like this?
