The Red Hat Certified Architect program provides a credential that represents these skills and knowledge. Through a combination of flexible requirements and recommended concentrations, Red Hat is providing a path for professionals to advance their careers and for its subscription customers to find the right architect.

A range of factors can influence the data center you choose. You should consider all of the factors listed in this white paper before deciding where to place your servers.

Unless you know the meanings of the five symbols regularly used in PowerShell, they can obscure the purpose and actions of a PowerShell script. There will always be new cmdlets to decipher. Each new operating system release and application version will include new and useful cmdlets along with new parameters for existing cmdlets. You can't memorize them all, but with the basic knowledge of these particular symbols, you should be well equipped to follow the logic of many scripts.

AWS is an incredibly rich ecosystem of services and tools, some of which have security aspects baked in (like S3 SSE), and others that provide overarching security capabilities (like IAM and VPC) that apply to many services. With regard to data storage, operating system, and applications, security functions largely the same in the cloud or on-premises software. Customers can and should continue to follow best practices that have served them well in their own data centers.

Accessing cloud-based resources, whether they be IaaS/PaaS/SaaS-based, is very convenient. With a browser and Internet connection, you are up and running. No driving to your work office, no need to log into the corporate network. Just open up your web browser and go. This convenience, however, comes with a security risk. All of your business work is conducted over an insecure communication network. Unlike your office network, where the network link between you and the data center is under corporate control and is physically secure, the cloud access link is over the Internet.

In this blog series, we'll get you up to speed on using the key tools listed in the PMBOK® Guide. First up, Work Breakdown Structure (WBS).

It’s not uncommon for different teams to be managing the virtual switch and physical switch configurations. This can make it very difficult to troubleshoot unless each configuration parameter has been gone through manually. There have been enhancements to the vSphere Distributed Switch over the past few years to address these operational challenges.

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.

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.

Complexity has always been a part of projects. But today, globalization, new technologies and changing markets have combined to add to the complexity. Today's projects have more stakeholders, more ambiguity and more politics than ever, and project managers need new tools and approaches to succeed. Join Alexander Stanisic and Michelle Moore of Global Knowledge for an information-packed hour on how to manage the complexity of the 21st-century project.

This paper explains uplink strategies for traffic coming in and out of a Cisco Unified Computing Solution (UCS) chassis. An uplink can be Ethernet, Fibre Channel, or FCoE and is a physical connection on the FI that leaves the UCS domain directed away from the B Chassis.

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).

With ever increasing demands for storage, system administrators often find themselves needing to add new storage to servers. This video provides step-by-step examples of how to partition, format, and mount new storage space using Linux.

A Dynamic Multipoint Virtual Private Network (DMVPN) can be used with other networks like Multiprotocol Label Switching (MPLS), but streaming multicast is accomplished quite well using "Default" and "Data" Multicast Distribution Trees (MDTs) with MPLS.

Cisco Unified Computing Solution (UCS) is a very popular and powerful solution. Cisco continues to provide updated UCS management options for the full range of data center installations.

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).

In many organizations, the Program/Project Management Office (PMO) is viewed as purely a cost center, so it becomes marginalized by additional layers of bureaucracy, oversight and cost. But the essence of the PMO and portfolio management in general is to add value to the organization. So how do organizations reconcile the cost of the PMO versus the value it adds? The short answer is to flip the conversation on its head and talk about the PMO as a revenue driver rather than a cost center. In this hour-long webinar, Global Knowledge PMP-certified senior product manager Daniel Stober will explain how, by focusing on efficiencies gained and reduced waste, you can shift the conversation from the PMO being a necessary evil to the PMO being critical for organizational success.

Young adults unable to find work, employers unable to fill jobs, a recent GAO study that reported substantial declines in telecommunication expertise — there has been a lot of news about the pervasiveness of skills gaps, their causes, the actual impacts and what to do about them. It’s rather confusing, because the term “skills gaps” has been hijacked to politicize an extremely wide range of issues.

Like it or not, Internet of Things (IoT) is upon us. There are a number of factors that will impact its adoption rate, and the inevitable privacy (or lack of) discussions will likely happen sooner than later. This is going to change the world as we know it, in many cases for the better. But we will need to keep an eye on the extent to which it invades our personal lives if it is going to be the positive force it has the potential to be.

While there are differences between the IP Multicast configuration in the IOS and the Nexus OS, the Protocol Independent Multicast (PIM) protocol remains fundamentally the same. If you feel comfortable configuring Multicast in the IOS, you should be able to acclimate fairly easily to the changes in the Nexus OS.

Multicast Sparse Mode and its derivatives are supported in the Nexus OS. This white paper explains how it has been implemented in the Nexus platform to provide optimum performance in both virtual PortChannel and FabricPath environments.

In this hour-long webinar, Global Knowledge instructor and ITIL Expert Michael Scarborough will share his knowledge and expertise on various aspects of incident management and problem management processes. He will help you understand the difference between incidents and problems and between incident and problem management, providing examples from his own experience to drive the concepts home. Michael will also provide an overview of who performs various incident and problem management activities in an organization.

Virtual storage area network (VSAN) and VMware View can offer cost savings and performance benefits compared to traditional SAN implementations for virtual desktop infrastructure (VDI). If you are starting a new desktop virtualization project, it would be wise for you to take the time to explore your options and compare VSAN to other options.

Dynamic Access Control (DAC) in Windows Server 2012 lets you manage access to documents in ways that go beyond classic NTFS (New Technology File System) permissions. For example, if you want to allow a set of users in an office across the country or across the globe read-only access to files relating to the Wind Turbine Project, DAC can do the job.

There are two types of virtual switches available using vSphere, the vSphere Standard Switch and the vSphere Distributed Switch. The vSphere Standard Switch (vSwitch or vSS) resides in and is manually configured and administered on each ESXi host. The vSphere Distributed Switch (dvSwitch or vDS) provides similar functionality but is centralized to vCenter Server and is more featured. This white paper will cover the vDS architecture as well as an overview of many of the different features that are exclusive to the vSphere Distributed Switch.

In many of today’s enterprise data warehouses and decision support teams, data scientists and data visualization specialists have reached near rock star status. This is in large part due to their ability to produce unique, clever and insightful perspectives with company information. These analytical gems often bypass obstacles to explain complex business data. This line of work is both an art and a science, and is generally most effective when the right blend of business intelligence tools are in place.

Through the use of automation, compliance, self-service portal, and standardization, Microsoft's System Center Service Manager can support the best practices found in the Information Technology Infrastructure Library (ITIL®) and the Microsoft Operations Framework (MOF). Service Manager also has built-in processes for Incident and Problem management, Change and Configuration management as well as Asset Lifecycle Management.

Mobile payment systems have solid promise to become the dominant means of financial transactions, but there are some hurdles to overcome. Apple Pay might be the dominant force today, but Google Wallet and others are not far behind. The year 2014 was when digital and mobile payment systems became known to a wide range of the general population, while only techno-enthusiasts were aware of the options in the four to five years prior. Thus, mobile payment systems are not new, but customers and merchants are quickly adopting them now that they have become popular. It still remains your responsibility to thoroughly research any mobile payment option before implementing it. It is your money and you have the burden of ensuring that it has the best protection possible.

Discover how the enhanced performance and reliability of Amazon Aurora will help AWS customers reduce performance bottlenecks in their applications. The relatively low cost of Aurora will tempt many customers to migrate workloads to this implementation of RDS.

Change is no longer an isolated event. In the digital world, professional and personal change is constant. It is the new normal. Today's leaders and teams are asked to handle relentless upheavals, while still being expected to deliver on their short-term goals. To succeed, they must toggle between the often-conflicting priorities of today's profits and tomorrow's growth. Organizational change management has been documented and many approaches exist; the same can be said for personal change. But rarely have organizations holistically thought about how these two drivers of positive change can collectively enable ongoing success. Join Jocelyn Bérard, Global Knowledge Vice President, International Leadership and Business Solutions, and Phil Buckley, Managing Director at Change with Confidence, for this informative hour-long webinar to learn a powerful and practical framework to help you manage organizational and personal change.

Kirsten Lora, our senior product director, discusses how Global Knowledge's Business Transformation Services prepare your employees to support your organizational change.

In this video, instructor Glenn Weadock explains the Windows 7 library concept and how it replaces the traditional "My Documents" user profile folder by adding the Public profile to the user profile.

Times are changing. Attacks are becoming much more sophisticated and hackers are exploiting human vulnerabilities to gain access to enterprise networks and private information. Employees and end users want to help protect your company's sensitive data, we just need to motivate them as to why they should care. By educating your employees on security best practices and current human vulnerabilities, you can take a step forward to ensuring you're not a part of the many organizations that are breached.

Now that we are moving towards IPv6, the logical move would be to also run OSPF for that protocol suite, which makes sense and reduces the learning curve for implementation and support. But, that would mean that you have to run two OSPF processes — one for IPv4 unicast and one for IPv6 unicast. That means two sets of policies have to be applied, including security for OSPF itself. Running OSPFv3 for both IPv4 and IPv6 reduces the number routing protocols and the configuration that goes with that. It makes it easier to implement policy in a consistent way for both protocol suites.

What is PBR? Policy-Based Routin (PBR) is the process of using a route map to match on something more than the destination and then defining the path out of the router based on those conditions. PBR could match on destination only, but typically we would match on more. PBR is considered to be an exception to the RIB and is looked at before examining the RIB.

What’s the difference between high availability and fault tolerance in VMware vSphere? This article elaborates on first configuring high availability and then layer on the fault tolerance capability. Learn more.

Business Continuity and Disaster Recovery (BC/DR) planning is the process of developing the plans, processes and procedures to respond to the range of incidents. We start with understanding the essential functions of an organization, called Business Impact Analysis (BIA). In life, we set the same priorities: protection of family and friends, shelter, food and water and other life-giving essentials.

Amazon Redshift opens up enterprise data warehouse (EDW) capabilities to even the smallest of businesses, yet its costs, security, and flexibility also make it appealing to the largest of enterprises. It allows companies to easily and conveniently scale their EDW needs both up and down, and as a managed service, it allows your team to offload all of the "undifferentiated heavy lifting" of building and maintaining an EDW. Its raw storage costs are about one-fifth to one-tenth of traditional in-house EDW, and AWS has taken great care to ensure its performance is still competitive with those in-house solutions. Before deciding to use Amazon Redshift, however, it's important to understand what it is and is not.

The Microsoft Assessment and Planning (MAP) Toolkit is an free inventory, assessment, and reporting tool from that helps you assess your current IT infrastructure and determine the right Microsoft technologies for your IT needs.

One of the main weapons of organized crime on the Internet is the use of junk email, also called spam. Hackers use spam for a number of purposes such as selling counterfeit products (medicines, particularly) to steal your personal or financial information, or to infect your computer with spyware and malware. This malicious software can then hijack your computer and your Internet connection to help propagate itself.

Public Key Infrastructure (PKI) can become a fairly complex environment and deployment, as it involves multiple components that all need to work together smoothly. Understanding the theory of how it all works will help in building a solid foundation for this complex technology in your organization. Although there is always something new to learn in PKI, this white paper gives you a great overview of the core configuration of your Microsoft CAs.

This white paper explores the native AWS storage solutions, enabling you to deliver applications in the cloud in the most efficient, cost-effective, and secure manner. In terms of storage, it's important to understand the characteristics of each AWS storage option so that you can implement one or more AWS storage services to meet your needs. Often, you'll find that utilizing multiple storage options together will give you the best outcomes.

You will learn how many organizations approach change management as compared to how best practices dictate that change management should work. Global Knowledge instructor and ITIL Expert Michael Scarborough will fill you in on the purpose of change management and the difference between change management and change tickets. He will provide a high-level guide for establishing a change management process that uses real-world examples as its basis.

Cisco provides a wide array of connectivity and isolation tools within the datacenter. This white paper addresses Virtual Routing and Forwarding (VRF), which is a Layer 3 isolation mechanism for routing protocols.

Pen testers beware. Whether you believe you know and understand all the potential legal issues, read on. First of all, a penetration test or “pen test” is a method that’s used to evaluate the security and/or vulnerabilities in a network. This test is normally conducted externally wherein the tester is attempting to hack a network or computer. Breaking into computers and networks is illegal under the Computer Fraud and Abuse Act (CFAA), and depending on your activities and other factors, other federal laws and state laws may be broken.

One of the advantages of vSphere is that you can move a virtual machine from one location to another, across servers, storage locations-even data centers. Physical servers don't have that ability and that can have many implications for disaster recovery, availability, and so forth. This white paper explains why migrations are useful, the methods that vSphere makes available for you to manually move a virtual machine (VM), and how vSphere can automate the process for you in various scenarios.

As I’ve stated before, I like Border Gateway Protocol (BGP). I think it’s an interesting protocol, and yes — it’s complicated, but I guess that part of why I like it. There are a lot of knobs to tweak in BGP, maybe too many, but that’s another post. Anyway, we are now running BGP version 4 and it has had extensions written that support more than just IPv4 unicast routing. We now have IPv4 multicast, IPv6 unicast and multicast, VPNv4, VPNv6, and a few others.

Discover how Network Functions Virtualization (NFV) will revolutionize IT and change the way you think about network connectivity and perhaps even application development. This white paper is written for networking professionals but it may offer valuable insight for those in cross-functional roles such as DevOps, server virtualization, and data center management.

The bad guys just keep getting better! No matter how much patching and tweaking we do, the bad guys' constantly changing tactics and techniques continue harming our networks, stealing and damaging data, and just generally screw things up. What motivates someone to do such terrible things in the first place? How have these hackers changed and improved? What kinds of attacks are popular now and why? In this hour-long webinar, security expert, former hacker and Global Knowledge instructor Phillip D. Shade will provide insight into understanding the latest hacking techniques, what the current threat landscape looks like, and suggested countermeasures to mitigate threats. He will include specific examples of the current threat landscape, including data mining, social engineering cyber threat terminology, man-in-the- middle attacks and Denial of Service (DoS) attacks.

Having options in life is usually a good thing. Do you want a cheeseburger or pizza for lunch? Water or sweet tea? And, if you’re going to take a Microsoft certification exam, do you prefer to take it at a Pearson VUE Authorized Test Center or in the comfort of your own home or office?

Communication in our work and personal life has been dramatically transformed, not only by technology, but also by new practices and habits. At the same time, numerous studies show that communication is one of the top critical skills required to be successful. In fact, because of the way organizations and jobs are evolving, the importance of communication keeps increasing for professionals and leaders. This hour-long complimentary webinar is not about how to maximize your LinkedIn contacts or attract more Twitter followers. Jocelyn Bérard is a psychologist specializing in human performance and will share innovative ways to influence others through communication. He will also help you raise your knowledge and awareness about your personality traits and personal characteristics, how they impact communication and how to use them effectively.The digital age is here and you can't control it. But you can certainly improve and better use the human side of your communication.

Where should you apply the CSS, and why are there two places to apply it? One approach is to pick one of the parameters and apply the permissions there. Quite often, an administrator will pick the phone-level CSS and configure it there so that it applies to all calls made from all lines. The goal is to specify what partitions are allowed to be called. 

For project managers, meeting stakeholder expectations means that you have to know what the expectations are to begin with if you are ever expected to meet them. After expectations have been set, follow up with your stakeholders to ensure that the expectations haven't changed. People change their minds often, so communicate in order to influence their perceptions and expectations. You may be surprised how simple communication and understanding expectations can positively affect your next project.

PowerVM is the virtualization environment for AIX, Linux, and IBM i running on the IBM POWER hardware platform. This white paper provides an overview of PowerVM concepts, architecture, terminology, and capabilities.

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.

For smaller companies, configuring a dial plan to account for variations in dialed numbers is often not a problem. However, companies that are larger and more global in nature encounter a number of issues when designing their dial plan approach.

Michael Scarborough and Ryan Ballmer, co-authors of Global Knowledge ITIL courseware, discuss how to become an ITIL expert.

Most of us have been involved with an e-Learning design project that has not delivered its intended impact. Across organizations, remarkably similar but preventable mistakes are made in the design and development of e-Learning that can frustrate learners, reduce effectiveness and ultimately impede success. Small missteps early in the design process can lead to costly problems in the development and implementation stages. This session will present 5 common mistakes e-Learning professionals make. For each mistake, evidence-based best practices will also be shared to help prevent their occurrence in the future. The evidence-based best practices can serve as a design guide for successful e-Learning projects of all types. Finally, approaches will also be discussed to help organizations integrate evidence-based best practices into their e-Learning design efforts.

Border Gateway Protocol (BGP) is a fascinating protocol because there are a lot of things that can be done with BGP. However, there has always been an issue with BGP, which is convergence (the time the network or protocol takes to accept change). BGP was designed for scale, not speed, so it’s something that we’ve had to tolerate from its inception.

License provisioning has always been a bit of a challenge in the CUCM environment. Prior to CUCM v9.0, licensing was managed on a per-cluster basis with each cluster requiring its own license files that were tied to the media access control (MAC) address of the cluster’s publisher. This approach to license management was limiting in the fact that one cluster might have unused licenses while another cluster may be at its limit and sharing between clusters was not possible.

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.

You are a problem. You are a risk to your employer. The actions you take and the activities you perform at work, online, and even in your personal life put your employer at risk. You need to know how you are a security risk to the organization and what you can do to reduce or eliminate those risks. In this paper, I discuss ten common risky behaviors that typical workers engage in and what you can do to avoid being the weakest link in your company.

Occasionally I am asked to configure the ability to block calls based on Caller ID. Prior to Cisco Unified Communications Manager (CUCM) v8, the only way to block these calls was to configure voice translation rules and profiles on the gateway receiving the calls. This has changed in CUCM v8 with the introduction of an additional parameter in translation patterns: Route Next Hop By Calling Party Number.

In this video, instructor Charles Strother does a quick overview of what is needed to install a Read-Only Domain Controller (RODC) in a Windows Server 2008 environment.

Increased interconnectivity via machine-to-machine (M2M) communications, the IoE, and smart systems holds profound implications for how business trends continue to evolve. In terms of M2M growth, key developments in security will be essential, from the design and manufacture of devices to more robust cloud security and ensuring the integrity of wireless data transmissions. Without these safeguards in place, organizations and industries that rely on M2M will continue to place themselves at risk.

With VMware's recent release of the Horizon Suite (specifically View 6), VMware has taken the performance and usability features and put them all under the Blast moniker. This category of features is grouped from a marketing perspective but will retain their technical terms in the documentation, similar to how the term vSphere encompasses both ESXi and vCenter. Learn about the various features of the components that comprise the Blast family, including a brief discussion of what they are, improvements in version 6, and any notes or requirements for implementation.

Have you ever Googled yourself to see how much of your personal information is online? In many cases it can be pretty scary and include things like your home address, phone number, likes, dislikes, etc. One young man searched for himself and found all of his banking information online. In that case it turned out to be a mistake by a bank employee, exposing the banking information of 86,000 customers.
