Internetwork Expert has announced more lab racks coming online in November. Most important is the new time slots which recognise that not every customer lives in America and will suit more customers globally.
I am seriously considering whether to undertake my second CCIE exam by doing the CCIE Security. Since the credit crunch has created a downturn in the market it is the best time to study. I am reviewing the training resources available and deciding which products might be worth purchasing.
