The new CCNA Security 640-554 exam has come to replace the old CCNA Security 640-553 exam. This exam is new so it will need some time to put up materials for this exam. In the meantime, we create the “Share your (new) CCNA Security Experience” for everyone to share their experience after taking this exam.
Please share with us your experience after taking the CCNA Security 640-554 exam, your materials, the way you learned, your recommendations…
