How do you measure the experience and knowledge of an IT professional? One way is through certifications. Earning any certification is a notable achievement, though not all certifications carry the same perceived worth.

No matter which IT field you're working in, there are several skills that are useful for every IT professional to know. Here, seven experienced IT professionals working in the networking, programming, project management, and security fields, share what they believe a...

Look back at the some of the highest paying IT certifications of 2020.

The question of how a project manager working in a functional or matrix organizational structure gets team members to perform is asked in almost every project management class I have taught.

In this series, we are looking at six things that can trip up project managers. We’ve covered the hazards of overcommitting, how to provide feedback, the importance of taking responsibility, staying focused, and what leading from the front can actually look like. Finally, we’ll take a look at handling team input.

This Certification Prep Guide provides an overview of the current Project Management Professional (PMP)® certification and offers helpful tips that you can use when preparing for your PMP certification exam.

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.

This paper proposes a unifying model for project plans. A distinction will be made between the outputs of project planning and the project plan itself. The significance of this distinction is to allow projects of all types to be described at a high level, in a common language, regardless of the type of analysis used to develop the plan.

The CCNAX - CCNA Routing and Switching Boot Camp is a great option to obtain Cisco Routing and Switching skills while pursuing the CCNA Routing and Switching certification. 

The term "life cycle" implies two things: that a process is perpetual and that the sequence of events is obligatory or uni-directional. There is no beginning or end to a life cycle and the sequence of events cannot change. A seed cannot go directly to being a mature plant nor revert back to the blossom stage.

Project procurement activities are often managed by specialists. By this I mean that the procurement department takes over responsibility for purchasing and contract management from the project manager. As a result of this separation of responsibilities, the steps and stages of procurement are often poorly understood by PMs. In this and the next few blog submissions, I will attempt to shed light on procurement activities and relate these activities to the PMI PMBOK.

The tools described in this white paper are essential PM tools. Tools that will best be used, regardless of the project, are the WBS, communication model, and the precedence diagram. The other tools will be needed depending on the project.

I attended a meeting this week with a customer of mine and a potential new vendor. The new vendor was there to pitch his configuration and setup service offerings for a specific ITSM toolset. My customer has already had one bad experience with an ITSM tool configuration vendor who promised one thing and delivered much less. He ended up with a tool that’s minimally used and not configured to match his business needs. He’s looking for a vendor that can understand his business needs and priorities and quickly help him get his tool configured and working in a short time frame. Then the topic of standard changes came up. My customer asked for examples of standard changes. The vendor responded, “Server reboots are an example of standard changes.”

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicating ideas as well as creating new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.

Diane Teare, Global Knowledge's Cisco Course Director, discusses the advantages to taking our CCNA Boot Camp.

Projects are a social endeavor. Traditional project management approaches have shied away from the social advantages a more agile project environment brings. By nature, we are storytelling, pattern seeking and social people. We need colocation to shine truly in a project environment.

The process of learning how to subnet IP addresses begins with understanding binary numbers and decimal conversions along with the basic structure of IPv4 addresses. This paper focuses on the mathematics of binary numbering and IP address structure.

ITIL® 4 Foundation Bridge is a new Global Knowledge course that addresses the specific needs of professionals who have already achieved the ITIL v3 Foundation certification and wish to upgrade to ITIL 4.

In support of software-defined networking, Cisco has introduced several products to strengthen networks and meet the increased demand for flexible and cost-efficient solutions. The Cisco SDN solution in the data center is ACI. Outside the data center the primary Cisco solution is DNA.

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.

Often, we don't have time to learn the reasons behind the standards we use. But learning what instigated a standard goes a long way toward not only understanding its importance, but also more easily and effectively applying it in your workplace. In this hour-long webinar, Global Knowledge instructor Keith Sorn will discuss common networking standards and explain how they were determined and why they are relevant. He will fill you in on things like why it's important to use proper color-coding standards when making cable and why the length limitations on wired cable are essential. He will also explain new standards, such as power over fiber.

This paper covers the configuration of IP Multicast with Multiprotocol Label Switching (MPLS) including the basics of Multicast with the Group Encrypted Transport VPN (GETVPN).

Depending on the switch vendor, the exact steps will vary on how to set up and configure VLANs on a switch. For the network design shown, the general process for setting up VLANs on the switch is:

For us wireless folks that aren’t stellar routing and switching guys, one of the most daunting network tasks is integrating our WLAN infrastructure with the existing wired infrastructure and its services. Understanding wired design topics is pretty fundamental to installing or managing any network, so it really should be on our priority list to spruce up those skills. To give you a nudge on your journey, let’s talk about DHCP for wireless clients.

While Apple has created many fine things, they were yet to be created themselves when Xerox PARC scientists created Media Access Control addresses. These MAC addresses are 48 bits or 6 bytes long, so they are also known as MAC-48 or EUI-48. EUI stands for Extended Unique Identifier. It is written in hexadecimal characters as shown below:

Wi-Fi networks have been misunderstood by much of the IT community since their inception. Even the reasons for this misunderstanding are kind of hard to understand. The result has been that myths about 802.11 (better known as Wi-Fi) networks have grown almost as fast as the technology itself. In this web seminar, we'll examine 11 common Wi-Fi myths and explore ways to use correct information to make your networks scalable, secure and satisfying for your users.

The 2021 revised and updated version CISSP (Certified Information System Security Practitioner) certification exam will be released on May 1, 2021. This new version of the popular CISSP exam will include a modest revision and re-organization of previously included topics, but will integrate a significant number of new topics.

A local area network (LAN) provides a path of communication, allowing the delivery of packets of data, voice, or video originating from the sender (logical source address) to the receiver (logical destination address). Ethernet is the most common LAN used. As you start to learn about networking, remember that communication and the movement of large numbers, whether it is people, cars, mail, or network traffic, have a commonality. Everything you know and use in your daily life can be compared to the way traffic moves.

The OSI model is a conceptual tool used to discuss and describe network functions. The use of a standard reference model is essential to communicate ideas as well as create new technologies. It is a good idea to be familiar with the OSI model, the features assigned to each layer, and examples of common protocols or technologies associated with the OSI layers.

Introducing new talent to an established organization can be difficult for many reasons. Seasoned employees may view the incoming new hires as "too green" or as not having the required skills to contribute in a meaningful way. They may worry about having to "waste time" teaching the newbies things that they should already know or get aggravated when the new employees are not familiar with "the way we do things around here." Additionally, it is difficult to know if the right new hires are being put into the right positions for their interests, abilities and talents. After all, a resume and an interview can only tell a hiring manager so much about the person they are bringing on board, and often talented employees are simply being put into a role that is not a good fit.

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.

Every manager wants to get the most out of every employee and maximize team cohesion and efficiency. Making your team members feel as if they are being heard, understood, and acknowledged is critical to any management strategy. Actively listening to team members’ thoughts, ideas, and challenges drives employee engagement and satisfaction, which drives better results. View the slide deck>>

The driver behind 802.11n is MIMO, or multiple input multiple output. This video explains how MIMO works to double your channel speed by sending two or more data streams over the same channel.

In this hour-long webinar, Global Knowledge instructor and PMP-certified project management expert Daniel Stober will look beyond the triple constraint model and focus on the true essence of project success: stakeholder satisfaction. Many project managers (PMs) fall into the familiar habit of managing based on the constraints of time, cost and scope. While all of these are important, managing them effectively doesn't guarantee project success if the PM fails to conduct proper stakeholder management. To manage stakeholders effectively, the PM has to set expectations. Once expectations are set, the PM must influence the perception of project performance with the stakeholder. Tune in as Dan explores methods you can use to accomplish that goal.

Good global project managers develop their own competencies, and those of their team members. We can use technology to bridge distance, but also focus on the human aspects of culture, work habits, management style, English as a mandated language, communication, and uncertainty. Perform a self-assessment and assess your team members, then look for on-the-job and other improvement opportunities. A good way to learn more about how to overcome these challenges is to become involved in the international community.
