Study Notes

IPsec and Network Protocols

Encapsulating Security Payload (ESP): Provides both authentication and encryption in IPsec.
Firewalls filter traffic primarily based on protocols and ports.

Network Connections

Use full duplex connections for simultaneous data transmission on network adapters connecting to switches.
T1 line offers a maximum throughput of 1.544 Mbps.

VPN and Leased Lines

Site-to-Site VPNs are ideal for connecting two companies collaborating on a project.
Examples of leased lines include DSL.

Wireless Standards

802.11ac routers are compatible with 802.11n (300 Mbps at 2.4/5 GHz) and 802.11a (54 Mbps at 5 GHz).

Wireless Networking Tools

A wireless bridge connects different wireless networks, such as 802.11a, 802.11g, and 802.11n.

Network Topologies

Ring topology connects computers in a circular layout.
Mesh topology connects every computer directly to every other computer.
Switch creates separate collision domains, allowing full duplex operations without collisions.

Server Roles and Network Cables

Remote Access role on Windows Server 2016 enables routing.
Single-mode fiber cables support the longest signal distances.

IP Addressing and Subnetting

Use ipconfig /all to find a computer's MAC address.
For 750 computers, a Class B IP address is recommended.
A Class C network's subnet mask for 192.168.1.0 is 255.255.255.0.

IPv6 and Network Addresses

Implement a multicast address for distributing packets to a group of IPv6 interfaces.
The local loopback address in IPv6 is ::1.

Name Resolution

LMHOSTS file resolves NetBIOS names to IP addresses.

VPNs and Security Protocols

A VPN creates a private tunnel over public networks.
Several tunneling protocols include PPTP, L2TP, and SSTP.

Ethernet and Port Specifications

Ethernet operates on Layer 1 of the OSI model.
Cat5 supports speeds of 100 Mbps, while Cat5e supports 1 Gbps.
Unsecured websites typically use port 80, while secured ones use port 443.

Classful Addressing

Class A example IP: 100.100.1.1; Class B example IP: 170.100.1.5; Class C example IP: 198.126.1.55; Class D example IP: 244.0.0.2.

DNS and IP Configuration Commands

AAAA records map hostnames to IPv6 addresses.
Commands related to IP address management include:
- ipconfig /release to delete an IP address.
- ipconfig /renew to acquire an IP address from DHCP.
- ipconfig /displaydns to show DNS cache.
- ipconfig /flushdns to purged DNS cache.

Tracing and Network Statistics

tracert is used to trace the path of IP packets across a network.
Use pathping to find packet loss statistics.
netstat -a displays all listening and established ports, while netstat -p tcp shows info for TCP connections.

Routing Protocols

RIP routing uses hop counts for route calculation, with a maximum of 15 hops.
