The traditional network engineering model of configuring one device at a time simply doesn’t scale to the growing needs of today’s network. Cisco's intent-based networks and software-defined networking solutions will enable your organization to meet the demands of network programmability and automation. The result will be greater network agility to support new applications while complying with increasing security needs.
This certification and exam guide discusses the various ITIL® certifications and what they might mean to you, your organization, and your career, as well as provide important test-taking tips for the ITIL certification exams. ITIL certifications help individuals validate their ability to demonstrate skills from a foundational to a mastery level of IT service management. ITIL certification can often be a key differentiator in the marketplace as well.
Take your VMware vSphere training to the next level—set up your own training lab environment. This paper is broken down into three major sections: the hardware required, the VMware Workstation configuration, and installing vSphere and vCenter (vC).
The process of subnetting is both a mathematical process and a network design process. Mathematics drives how subnets are calculated, identified, and assigned. The network design and requirements of the organization drive how many subnets are needed and how many hosts an individual subnet needs to support. Binary basics and IPv4 address structure were covered in part one of this two-part paper.
The methods we have used in the past to secure our networks won’t work for tomorrow’s networks. Cloud-based applications and multi-tenant environments require greater scalability, agility and control. Software-defined networking (SDN), such as that provided by VMware NSX, can deliver a new platform that transforms networking and provides for much more specific control of the security of your data and networked applications. In this white paper, author Bill Ferguson describes the microsegmentation of security and illustrates how you can use NSX to provide security that works on today’s and tomorrow’s networks.
What path you decide to take to earn your Cisco Certified Network Associate (CCNA) Routing and Switching certification will depend on a number of factors including your availability, willingness to work long hours and your ability to absorb a lot of information in a short period of time. This white paper includes self-assessments and training recommendations to help you figure out if taking the CCNAX Routing and Switching Boot Camp or taking two separate ICND1 and ICND2 courses is the best fit for you.
With the release of vSphere 6, there are big changes that allow for zero downtime with data access and recovery. The new features enable live migrations across long distances with enhanced vMotion features, datastore backup capabilities around Fault Tolerance upgrades and a new Content Library. These advances help you keep up to date with the latest in server virtualization.
When properly utilized, VLANs and trunks provide flexibility, stability and ease of troubleshooting. This paper provides technical details about VLANs and trunks, along with design options at a basic to intermediate level. Recommendations and commands are included throughout.
Switches play a vital role in moving data from one device to another. Specifically, switches greatly improve network performance, compared to hubs, by providing dedicated bandwidth to each end device, supporting full-duplex connectivity, utilizing the MAC address table to make forwarding decisions, and utilizing ASICs and CAM tables to increase the rate at which frames can be processed.
The first big push toward implementation of IPv6 was mobile devices. Now, one of the driving forces is the Internet of Things. As the name implies, this means everything, including machine to machine communication (M2M).
