IT Infrastructure and Operations Course

By the end of this course, you should be able to:

• Explain common network types and characteristics, and compare the functions of each OSI model layer.
• Configure a basic SOHO network and apply CompTIA’s troubleshooting methodology to diagnose and resolve connectivity issues.
• Summarize Ethernet standards and differentiate copper vs. fiber-optic cabling and connector types.
• Plan rack-based physical installations for server rooms/datacenters and deploy and troubleshoot Ethernet cabling.
• Deploy networking devices and explain common network interfaces.
• Configure common Ethernet switching features and troubleshoot transceiver and switching issues.
• Explain IPv4 and IPv6 addressing schemes and IPv4 forwarding.
• Configure IP networks and subnets, test host IP configurations using appropriate tools, and troubleshoot IP networks and hosts.
• Compare and contrast core routing concepts, including dynamic routing principles.
• Install and troubleshoot routers, and explain tiered switching architecture and VLAN implementation.
• Compare and contrast transport protocols and use command-line tools to scan and validate network ports.
• Explain network addressing and name resolution services, and configure and troubleshoot DHCP and DNS.
• Explain the importance of time synchronization and the role of NTP, and describe common network services (web, file/print, database, email, and voice).
• Explain how high availability is provisioned using redundancy and load balancing.
• Explain the purpose of configuration and change management documentation, and use discovery/monitoring and event management tools to identify assets and maintain network availability.
• Use packet analysis and traffic metrics to troubleshoot network performance issues.
• Explain common security concepts, including how to distinguish risk, vulnerability, threat, and exploit.
• Summarize common attack types and their network impact, and explain the importance of audits and regulatory compliance.
• Explain identity and access management concepts and differentiate authentication and directory management protocols/standards.
• Implement defense-in-depth controls by enforcing device compliance and applying security rules (e.g., ACLs and content filtering) to manage network traffic.
• Explain the importance of network segmentation, including the use of trusted and untrusted zones.
• Describe the security implications of IoT/IIoT and explain the importance of physical security controls.
• Summarize key wireless standards and capabilities.
• Install, configure, and troubleshoot secure wireless networks.
• Summarize WAN provider and Internet access types for enterprise connectivity.
• Compare and contrast VPN topologies and protocols, and explain remote host access and management methods.
• Explain data center and storage network architectures and summarize core cloud concepts.
• Summarize how software, coding/automation, and Zero Trust principles are applied in modern network environments.
