MTA: Networking Fundamentals - Exam: Microsoft 98-366

Explore local area networks, wide area networks, and VPN concepts within MTA networking fundamentals, including network topologies, wireless, and wireless security.

Explore what a network is, a group of two or more connected computer systems, covering end devices, clients, servers, firewalls and routers in LAN and WAN contexts.

Identify how internet, intranet, and extranet differ and why DMZs and VPNs enable secure external access. Learn how firewalls protect the internal network and support remote work and file sharing.

Learn how virtual private networks create secure tunnels over the internet to connect remote users and sites, using IPsec and encryption for site-to-site and remote access VPNs.

Explore local area networks by examining Mac addresses, loopback interfaces, and switches like the HP 2510, and preview IP addresses, VLAN basics, and subnetting essentials.

Explore local area networks and vlan concepts, comparing wired and wireless connections, with a vlan 27 example to isolate the HR server from engineers, and discuss reliability and range considerations.

Learn how wide area networks connect multiple local area networks through routers and VPN tunnels, using internet services from ISPs to link offices globally.

Explore wireless networking fundamentals, from 802.11 standards and real-world speeds to SSIDs, 2.4/5 GHz frequencies, channel bandwidth, and security with WPA2 and 802.1X.

Examine network topologies, focusing on star and mesh designs, including physical and logical diagrams, to understand redundancy and how spanning tree prevents loops.

Explore network infrastructures, including Lan, Wan, and VPNs, and learn why VPNs are important in real-world networks.

Explore core network hardware, including switches, routers, and access points, and see how these devices work while understanding how a router operates and what a MAC address means.

Explore why switches matter in networks by comparing layer two, three, and four switches, detailing collision domains and VLANs, and managing ports and uplinks via CLI and web interfaces.

Explore the main differences between hubs and switches, including collision domains and half-duplex speeds, and introduce VLANs, trunks, and tagged ports.

Explore how routers connect local area networks to form wide area networks, and compare static routing with dynamic routing using routing tables to determine the best path.

Learn how an access point connects wireless devices to a router over ethernet, sharing a LAN subnet, with WPA2 security, five gigahertz operation, and a named SSID.

Explore utm firewalls and network security, including stateful inspection, ips modules, and antivirus features. Understand how these devices act as edge routers with vpn, licenses, and rules for remote access.

Compare cable and wireless solutions to show why cable networks are preferred. Explore twisted pair, fiber optic, shielded vs unshielded cables, RJ-45, RJ-11, and EMI considerations.

Build a real home network to learn networking by setting up a VoIP router, servers, firewalls, core and access switches, and VMware to explore protocols and services.

Explore core network hardware such as routers, switches, access points, and firewalls, emphasizing security, then preview upcoming coverage of services and protocols.

Master OSI model concepts and essential network services by exploring subnetting, DNS, and DHCP, supported by two lectures, a document, and a quiz.

Explore OSI model and its seven layers, focusing on the top three—application, presentation, and session—with DNS, Telnet, DHCP, and web servers as examples, and groundwork for layers four to two.

Explore the transport layer of the osi model, comparing tcp and udp, and highlight port numbers, common services, and netstat usage for inspecting ipv4/ipv6 connections.

Explore IPv4 concepts including IP addresses, subnet masks, network addresses, and subnetting with examples like 255.255.255.0 and 192.168.1.7 vs 192.168.1.130, plus dhcp, apipa 169.254, private ranges, and nat.

Master subnetting basics with a practical IPv4 example, converting a /24 to a /27 with five subnets, and calculating networks, increments, and usable addresses.

Practice subnetting with more examples and questions, calculate broadcast and network addresses, and identify usable IP addresses in ranges like 192.168.1.6/29, using the increment and binary table.

Discover IPv6 fundamentals, including 128-bit addresses, unicast, anycast, and multicast, and absence of broadcast, while noting that IPv6 is not backwards compatible with IPv4 and can be tunneled with IPv4.

Learn how DNS translates domain names into IP addresses, including domain name servers, A and CNAME records, and the role of host files in name resolution.

Explore dhcp and ipsec in networking services, including server discovery, scopes, exclusions, and default gateway and dns settings. Learn how ike, esp, and rh secure vpn tunnels.

Explore TCP/IP and OSI models, compare their layers, and learn how the top three TCP/IP layers map to application, network, and data link/physical, to prepare for the MTA exam.

Explore network services and protocols, including ACI subnetting, DNS, DHCP, TCP, and IP, and understand how these concepts apply to roles in network engineering and support.

Learn to install Prtg in a VirtualBox lab, configure sensors for Windows server monitoring (CPU, memory, disk, uptime, RDP, Hyper-V, HTTP), and build network maps with live graphs.
