Discussion Questions
Question #1
 ARP: Harangue Resolution Protocol is the system of mapping an IP harangue to a Media Avenue Control. It, accordingly, serves the exercise of translating 32-bit haranguees to MAC haranguees, which are 48-bit and defect versa.
 DHCP: Dynamic Army Configuration Protocol allows the server to charm the aim of collection placed to a network and place them to a peculiar computer as an IP harangue.
 ICMP: Internet Control Message Protocol is truthd by devices on the network to detail whether messages are successfully grasping the magazine. The ICMP helps devices discbalance despatch issues athwart the network.
 SNMP: Simple Network Conduct Protocol truths agents in the catruth of advantage programs to mentor the network’s deportment and commerce and hoard the notification on a conduct notification vile (Rouse, 2019). The programmed advantage is usually loaded on devices such as routers, servers, or hubs.
 DNS: A lordship call serdefect remedy TCP/IP protocols test armys by their IP haranguees. DNS servers render army haranguees instead of giving truthrs the work of memorizing the lordship calls.
Question #2
 Bastion army: A specialized computer that impresss as a gateway from a social to a retired network. It is unprotected to the social network and withextinguished a firewall or among span firewalls as it logs avenue on a agency server (Bittlingmeier and King, 2003).
 DMZ: A subnetwork that faces ostensible to catruth a node that is unprotected to attacks precedently they grasp the deep network. The role of a DMZ is to apppurpose an extra lamina of guard.
 Dual-homed firewall: A technique whereby span network interfaces are placed among a trusted and untrusted network. The firewall is application-based, and its role is to agree safeguard utilitys to untrusted networks.
 Sheltered army: Both a agency server and a router are truthd as safeguard laminas. The role is to catruth a secretive network where the router is the highest to shelter ce disallowed avenue then the agency server impresss as the edifice server’s face purpose.
 Sheltered subnet: The truth of three components that impress as firewalls. Most routers are truthd, and they mould up the interior, manifest, and perimeter components. The role is to exhibit a social interface, buffer, and appenditional subnet.
Question #3
The four deep VPN avenue tunneling protocols are PublicVPN, PPTP, SSTP, and L2TP/IPSec. PPTP is disclosed as Point-to-Point Tunneling Protocol, and it is the easiest manner to truth. It requires singly a password, truthrname, and IP harangue to converge to the urbane servers. The protocol truths TCP ports to spurpose and hold facts athwart the network to the server. However, this manner was phased extinguished due to deep vulnerabilities that were inclined to attacks. There is then the truth of Lamina 2 Tunneling Protocol (L2TP) balance-and-above an Internet Protocol Safeguard (IPSec). This protocol encapsulates and encrypts facts hereafter creating dual safeguard measures ce the facts nature communicated athwart the tunnel. SSTP is disclosed as Guard Socket Tunneling Protocol, and it transmits facts through the SSL, which works in attention with the Transport Lamina Safeguard on the Windows OS (Athow, 2019). Ce the PublicVP, the protocol was familiar of-late, enabling public spring AES 256-bit encryption of facts packets nature communicated balance the network. Truthrs can chosen from a place of cryptographic algorithms, and the manner is attended on any OS.
