Which one should I take? 640-553 or 640-554?

Just noticed that the last day to take 640-553 is September.
I am wondering if i am interested in getting the CCNA Security, which exam should I take?
Option1. Prepare and Take the 640-553 before September
Option2. Prepare the new one: 640-554
In addition, If I decide to take 640-553, will it becomes invalid in my Cisco status after September?
Thanks.

If you feel you can pass the 553 before the expiration date then study away and give it a shot!

Eg. any new technology is only available in 554 only, but not 553?

If you are only just starting out however, I'd say go for the 554, I went through some simulators and could answer most questions based on the 553 syllabus - however I haven't had much exposure to CCP.
