Watch this recorded webinar as CompTIA’s chief technology evangelist and Global Knowledge’s federal sales director discuss how pentesting has morphed.

Spanning Tree Protocol (STP) is dead, or at least it should be. It’s too slow to converge when there’s a change, and it causes issues with performance because there is only one forwarding path. It was developed in 1985 by Radia Perlman at Digital Equipment Corporation to allow for redundant paths within a Layer 2 topology, which was great in 1985. In fact, it was huge! So much so, that it was later standardized by the IEEE as 802.1D, and we’ve been living with it ever since.

If you are considering career options or have been in the workforce a few years and are seeking a career change, you might want to consider training to become a computer support specialist.
