That depends on their configurations. For example: While it makes very good sense to include redundant physical links in a network, connecting switches in loops, without taking the appropriate measures, will cause havoc on a network. Without the correct measures, a switch floods broadcast frames out all of its ports, causing serious problems for the network devices. The main problem is a broadcast storm where broadcast frames are flooded through every switch until all available bandwidth is used and all network devices have more inbound frames than they can process.
The Cisco UCS is truly a “unified” architecture that integrates three major datacenter technologies into a single, coherent system: Computing Network Storage Instead of being simply the next generation of blade servers, the Cisco UCS is an innovative architecture designed from scratch to be highly scalable, efficient, and powerful with one-third less infrastructure than traditional blade servers.
“Twisted Pair” is another way to identify a network cabling solution that’s also called Unshielded Twisted Pair (UTP) and was invented by Alexander Graham Bell in 1881. Indoor business telephone applications use them in 25-pair bundles. In homes, they were down to four wires, but in networking we use them in 8-wire cables. By twisting the pairs at different rates (twists per foot), cable manufacturers can reduce the electromagnetic pulses coming from the cable while improving the cable’s ability to reject common electronic noise from the environment.
It’s common knowledge that earning an AWS certification is a great way to qualify your experience in the eyes of your peers and employer and to increase your organization’s proficiency with AWS-based applications. However, there is another benefit that has not be quantified until now. Results from the 2015 IT Skills and Salary Survey conducted by Global Knowledge and Windows IT Pro revealed that the average pay of four AWS certifications exceeded $100,000. While there is no guarantee that a certification equals a six-figure salary, it certainly couldn’t hurt.
