Training involves the true use of corporate resources – encompassing time, people and cost – to prepare employees to perform and contribute to the organization. While learning is a process, in the world of sales training that process must be accelerated. There’s a very simple reason for that: When salespeople are training, they aren’t selling. With sales training having the most visible link to the company’s financials, it’s imperative for salespeople to leave training ready to sell.

Last week in my post Low Tech Solutions to Survive a High-Tech World, I shared some common sense ways to avoid identity theft from a workshop at AFCEA’s West13 conference lead by Jeff Moulton, principal research associate at the Georgia Tech Research Institute. This week I’m going to share the second part of his workshop, “Seven Habits of Highly Secure People.”

Most network professionals have a high degree of awareness of the principles of Virtual Local Area Networks (VLANs) and the importance of trunk links use to carry this data between switches. The underlying theory involved is at the foundation of most certification courses, various Cisco Press books, and even in breakout sessions at many conferences. While the proverbial “big picture” of the process is straightforward enough to the initiated, some of the nuances can become somewhat vague. Dynamic Trunking Protocol (DTP) and its predecessor, Dynamic Interswitch Link (DISL), are used to automatically negotiate the establishment of a trunk, but the many options and settings can become more confusing than helpful.
