i just took my oracle exam and let me tell you, this exam dumps was a lifesaver! without them, iam not sure i would have passed. the questions were tricky and the answers were obscure, but the exam dumps had everything i needed. i would recommend to anyone looking to pass their oracle exams with flying colors (and a little bit of cheating) lol.

22. if you need to make sure that one computer in your hot-spot network can access the internet without hot-spot authentication, which menu allows you to do this? answer is ip binding and not wall garden. wall garden allows specified websites to be accessed with users authentication to the hotspot
