It may be NDA violation for anybody to answer your question Definitely you need to know what these technologies are and how to configure them.
Thanks for your reply, the reason I want to know because the book didn't talk too much about it, it was a brief definition with simple example. the author however mentioned that (for example EEM) is a huge topic that can not be covered in this book.
That got me wondering shuold I do more research to learn these and if so, how much should I learn.
If somebody goes to the exam without knowing BGP, I am sure you would say, mate don't bother taking the exam, because its an important subject.
thanks for your reply again.
There are core topics you would know. They are IGPs, BGP, VLANs etc. Without knowing them you will fail core task and therefore loose many points because you will not complete not only core tasks but all others too. For example, IP multicast tasks are based on IP unicast routing and you need IGP to be set correctly for it. So by failing 1-2 core tasks you obviously fail the entire exam.
All other topics are secondary. They are not so much critical. Theoretically you may fail many of them and pass the entire exam. All topics you mentioned are secondary as I can see. By failing NetFlow you probably loose only 2-3 points.
But Secondary doesn't mean Simple. OER/PfR, EEM, SLA etc. are rather complex and really huge.
Thanks for the explanation, you are a star, that has made a lot clearer to me.
