Descrizione:
This course is part of the official Cisco CCNP® curriculum and covers the skills that are required for CCNP certification. Students will learn to monitor and maintain complex, enterprise routed and switched IP networks. Skills include the planning and execution of regular network maintenance, as well as support and troubleshooting using technology-based processes and best practices, in a systematic and ITIL-compliant approach. Extensive labs emphasize hands-on learning and practice to reinforce troubleshooting techniques. The course is appropriate for enterprise network engineers with at least one year of job experience who are ready to advance their skills and work independently on complex network solutions. It is part of the official CCNP curriculum and covers the same skills that are validated in the CCNP certification exams. Cosa si impara Upon completing this course, the learner will be able to meet these overall objectives: Plan and document the most commonly performed maintenance functions in complex enterprise networks Develop a troubleshooting process to identify and resolve problems in complex enterprise networks Select tools that best support specific troubleshooting and maintenance processes in large, complex enterprise networks Practice maintenance procedures and fault resolution in switching based environments Practice maintenance procedures and fault resolution in routing based environments Practice maintenance procedures and fault resolution in a secure infrastructure Practice maintenance procedures and fault resolution problems in a complex environment CONTENUTO DETTAGLIATO: 1. Planning Maintenance for Complex Networks Applying Maintenance Methodologies Models and methodologies commonly used for network maintenance and the benefits that these models bring to an organization Select generalized maintenance models and planning tools that fit your organization Common Maintenance Processes and Procedures Essential network maintenance tasks Advantages of scheduled maintenance Key decision factors that affect change control procedures in order to create procedures that fit the needs of your organization Essential elements of network documentation and their function Plan for efficient disaster recovery Importance of network monitoring and performance measurement as an integral element of a proactive network maintenance strategy Network Maintenance Tools, Applications, and Resources Elements of a basic network maintenance toolkit Tools that support the documentation process and are appropriate to your organization How configuration, software, and hardware resource management software can improve disaster recovery procedures How network monitoring software benefits the maintenance process Metrics that could be used to measure network performance, the performance measurement process, and creating a performance measurement plan that is appropriate to your organization 2. Planning Troubleshooting Processes for Complex Enterprise Networks Lab 2-1 Debrief Applying Troubleshooting Methodologies Fundamental elements of a troubleshooting process Advantages of a structured network troubleshooting method Evaluate and assess common troubleshooting approaches Select a combination of troubleshooting methods that are appropriate to a specific troubleshooting scenario Planning and Implementing Troubleshooting Procedures Fundamental subprocesses of the generic troubleshooting process Formulate correct problem definitions and assign responsibilities Gather information in a structured manner Interpret and analyze the gathered information Isolate a problem through a process of elimination Formulate a hypothesis and evaluate the necessary actions to take after you have formulated a hypothesis Test a hypothesis and roll back if a hypothesis is not confirmed Integrate a solution into the existing network Integrating Troubleshooting into the Network Maintenance Process Evaluate the benefits gained by aligning troubleshooting procedures to network maintenance procedures Create and routinely update documentation as part of the troubleshooting process Identify abnormal network behavior by comparing actual behavior to a baseline created as part of the network maintenance process Implement communication processes that increase the effectiveness of the troubleshooting process Implement change procedures that are flexible enough to support the changes needed during troubleshooting and controlled enough to be integrated into the standard maintenance and documentation procedures 3.
