Cleared my SANS GCIA 503 on 19 March 2016. I went through Sans On demand Course-503 before giving the Test.Sans provide you 2 mock tests when you register for the exam. The Mock tests will give you a deep inside on how the actual exam will be like.
How to clear?
1) The Materials provided by Sans is enough to clear the exam. But you have to very clear wit the concept. Go through the book atleast 3/4 Times and get familiar with it. Indexing will help only when you are clear with the concept in the book
2) Go through the Exercises provided in the Work book. It is a must.. You may feel it unnecessary but I am repeating it is a must.
3) Be handy with the frame headers in the ********** and Packet decoding, which I felt will be the deciding factor in your exam
4) The mock test will be near in pattern with the real exam, So prepare well and give the mock test , the Questions wont repeat in the real test but pattern and concept of the questions in the real exam will be hovering around the one in the mock test
5) And last thing prepare well in advance it is not like , you come out of a blue and decide to write the exam in 7/10 days. Give time to it, have patience and prepare thoroughly then decide to give the real exam.
All the best.. and get Certified...
