This course guides you through the Common Body of Knowledge (CBK) recommended by the International Information Systems Security...

Overview/Description This course takes a closer look at the main enabling technologies and core components that allow clouds to function. While the cloud is not necessarily dependant on virtualization, it's widely accepted that any competitive cloud will utilize it. Infrastructural and network connectivity considerations of the modern datacenter are greatly influenced by the requirements of the cloud. Datacenter infrastructure and components must be designed to address security, scalability, disaster recovery, and redundant high-speed connectivity needed to provide a successful cloud service...

Overview/Description Troubleshooting skills are required by everyone who has responsibility for a network. The complexities of modern enterprise networks means that there is a vast array of devices, software, and infrastructure components that have the potential for failure - therefore causing a loss of connectivity on the network. This course describes the different networking problems and issues that can arise, as well as how they can be addressed. This course prepares the learner for the CompTIA Network+ 2012 certification exam N10-005. Network+ is sometimes referred to as N+ or Net+....

Overview/Description The choice of network media depends on a number of factors. Speed and bandwidth requirements and budgets are probably the two main considerations, although the site itself can play a part. In new construction, for example, it may make sense to install the more expensive fiber optic media rather than incurring the cost of an upgrade down the road. Upgrades to older sites can be expensive and may not even be possible in some cases. This course describes the different available network media, including twisted pair cable, coaxial cable, fiber optic cable, and wireless media...
