Subnetting is the practice of dividing a given block of addresses into sub-units. This is done to meet organizational, security, and performance needs. In this course, you'll learn the differences between fixed-length subnet masks and variable-length subnet masks. You'll explore how subnet values are calculated and how to use VLSM to subnet a given block address. Finally, you'll learn how VLSM relates to Classless Inter-Domain routing. Address Resolution Protocol is a fundamental protocol that maps an IP address to a target MAC address. In this course, you'll also learn the purpose of address mapping, the characteristics of the ARP cache, and ARP commands. In addition, you'll learn about each of the fields in an ARP message and other ARP capabilities. While the majority of network communications gets done using a one-to-one transmission, some forms of communication are better served using a one-to-man transmission, like a television broadcast. The Internet Protocol supports this one-to-many type of communication with the Internet Group Management Protocol. You'll learn about the uses of multicasting and its main characteristics. You'll also explore the role of IGMP in multicasting and how multicast routing works. This course was originally created by Global Knowledge (GK).

Then you'll discover Wi-Fi concepts such as access points, WLAN controllers, SSIDs, and Wi-Fi channels. Finally, you'll learn about wireless tools, security, authentication, encryption, and performance. This course was originally created by Global Knowledge (GK).

The Analysis tool in HP LoadRunner is used to analyze test result data. Discover how to generate an analysis session with HP LoadRunner 12, how to access graphical representations, and how to create custom graphs and reports.

The PowerShell environment can help you in the management of SQL Server. Learn how to use SQL PowerShell to monitor and handle errors, restore databases from backups, and create SQL audits.

HP LoadRunner is end-to-end load-testing software for system performance measurement under load. Explore performance testing and LoadRunner, including the installation of the software components.

WebLOAD is a load testing tool that can be used to test performance and scalability. During this course, you will explore features that enable successful testing, monitoring, and correlation. Topics in the course include recording, script debugging, parameterization, correlation, test load scenarios and test data collection. Other subjects include customizing and predefining a dashboard, actionable intelligence, application performance management (APM), server monitoring, and root-cause analysis. As you progress, you then learn how to identify WebLOAD's supported web protocols and technologies, including HTML5, SOAP, JSON, Angular, and many others. As a review exercise, you will use WebLOAD to configure a report template, generate a PDF report, list dashboard features, use predefined dashboards for an analysis, and customize a dashboard.

Feedback often gets overlooked in lieu of the pace at which business moves, but organizations ignore the importance of feedback at their own peril. In this course, you'll learn how DevOps thrives by amplifying feedback, beginning with the principles and practices of amplifying feedback and the importance of identifying problems as they occur. Then you'll discover the importance of pushing quality closer to the source, optimizing for downstream workflow, telemetry metrics, monitoring, and alerting, telemetry from an architectural standpoint, and levels of telemetry architecture. Finally, you'll explore the role played by alerting in automation, system monitoring tools and their uses, log aggregation tools, DevOps metrics, how telemetry can be used to anticipate problems, hypothesis-driven deployment, and A/B testing and how it relates to hypothesis-driven development. This course was originally created by Global Knowledge (GK).

New technologies are providing a positive impact on the implementation of DevOps, and no recent technology has been more impactful than virtualization and the cloud. In this course, you'll explore architecture and virtualization in DevOps, beginning with the concept of containerization, how paying attention to architecture can reduce risk in deployments, and the role of microservices in software deployment. Then you'll learn about the strangler pattern and the role it plays in re-architecting, the blue/green deployment pattern as an architectural approach, and how the move in IT towards virtualization and the cloud is enabling the DevOps movement. Finally, you'll discover change review and coordination as it relates to flow optimization and the basic steps for optimizing flow. This course was originally created by Global Knowledge (GK).
