Network and Systems Administrator Technical Training

Identify two paths for learners—job seekers and those developing skills—and preview two videos on hands-on setup, the job-seeking focus, and growing within your admin role.

Explore the OSI seven layers and how ISO standards govern device interoperability, from application traffic to physical cabling, via encapsulation and de-encapsulation.

Learn to capture and analyze network traffic with Wireshark, compare TCP and UDP behavior, apply filters, read IP and MAC layers, and understand denial of service basics.

Take a quick check to ensure you practice with Wireshark on your virtual system, build home labs, and replicate demos to gain hands-on experience as a network and systems administrator.

Learn how to provision a brand-new Cisco router or switch using a console cable, connect a laptop via RJ-45 to DB-9, and use terminal software to access the device.

Capture and analyze IPv4 headers with Wireshark, select a specific network interface card, and learn TCP and UDP protocol numbers, plus SPAN and RSPAN concepts for remote monitoring.

Explain the difference between class ranges and RFC 1918 private addresses, and how private IPs, public IPs, DHCP, NAT, and VPNs enable communication in home and enterprise networks.

Explore the DHCP process (discover, offer, request, acknowledgement) and how a DHCP server assigns IP addresses to hosts, with UDP ports 67/68 and broadcast 255.255.255.255, and the relevance of DHCP snooping.

Explore how a DHCP server with two NICs assigns IPs from separate subnets, one per NIC, and how APIPA addresses in the 169.254.x.x range appear.

Install and configure a dhcp server to automatically assign ip addresses to hosts, reducing administrative overhead. Verify dynamic ip allocations in a practice lab environment.

Install and configure a dhcp server to automatically assign ip addresses to hosts on the network. Create and activate a 192.168.0.0/24 scope with a default gateway, then verify allocation.

Explore how DNS resolves domain names to IP addresses via host files, routers, and resolvers, with root servers, top-level domains, and common records such as A, AAAA, and CNAME.

Install and configure an internal dns server and a secondary dns server for high availability, translating hostnames to ip addresses and managing dns records in a windows lab.

Learn how ipv4 addresses identify each host by combining network id and host id in a 32-bit dotted decimal address, and examine ipv4 header fields, ttl, and fragmentation basics.

Master essential Windows Server services, including DNS name resolution, host file mapping, Wins, and DHCP, plus Active Directory concepts for domain structures and group policy.

Identify storage technologies and architectures, including RAID, NAS, SAN, and iSCSI, and manage disks, partitions, volumes, and file systems with hot spares and fault tolerance.

Configure a static IP address and the preferred DNS server, then verify with ipconfig /all and ping the domain controller.

Carry out practice lab tasks by installing Active Directory Domain Services using PowerShell commands, copying and pasting commands from the content viewer, and monitoring progress in server manager.

Promote this machine as an additional domain controller using the command line, then verify completion after system restart and complete the replica domain controller setup.

Configure Active Directory sites and subnets to enable inter-site replication by creating a new site named America-HQ and adding subnets 192.168.0.0/24 and 192.168.1.0/24 associated with the site.

Create an inter-site IP site link and configure its schedule to manage Active Directory replication, then move a domain controller to the appropriate site using Active Directory Sites and Services.

Monitor and troubleshoot Active Directory replication using PowerShell and repadmin. Execute manual replication of AD DS data through Active Directory sites and services.

Manage Windows user and group accounts using Active Directory and local groups, assign permissions and group policy, and understand domain versus local administrator roles.
