Response
At the end of Step 19
in “Configuring a Centos Network Interface Manually With the Network Service,” you are asked to resolve the addresses for three different names that all result in the same IP address. Which version would you find most useful? Explain why.
For me, simple is almost always better; therefore, I would probably say the, “host cserver” option would be the most useful for me. It is the simplest and doesn’t require knowing the IP address.

Explain why it is not necessary to create an inbound rule on the internal 192.168.12.10 Windows server so that it can receive the response (ICMP echo reply) from the internal 192.168.12.11 Windows server.
Both machines are on the same LAN; therefore, there are both already mapped.
Explain the advantages and disadvantages of having the firewall disabled at startup in the Linux operating system.
Advantages of having the firewall disabled at startup in Linux:
Ease of Configuration: It can be easier to configure network services without a firewall.
Performance: There might be a slight increase in network performance due to the elimination of packet inspection.
Disadvantages:
Security Risk: Without a firewall, your system is exposed to various threats from the internet.
Vulnerability: Malicious users can exploit open ports and gain
unauthorized access to the system.
