Exam MD-100 topic 4 question 6 discussion

If only all questions are this easy! haha

It's ICMPv4 and not IGMP. Note the G instead of C IGMP is a protocol used by hosts to communicate with multicast routers in order to join or leave multicast groups on a network. It is used to manage multicast traffic on a network, which is traffic that is sent to a group of hosts rather than just one specific destination host.

It's a little confusing, I know. Once and for all, imagine flabezerra and examtopics. flabezerra wants to ping examtopics. flabezerra will send packets and receive response. From this perspective, examtopics was able to RESPOND to flabezerra’s REQUEST because of examtopics own firewall configuration INBOUND Rule > File and Printer Sharing (Echo Request - ICMPv4-IN). Now replace the statement: examtopics needs to ensure that they will RESPOND to ping REQUESTS. Regardless of the default setting for inbound rule for ICMPv4, you need to create, you need to ensure, a rule as the question statement. And the rule to be created must be inbound.

Regras de entrada Quando você instala o sistema operacional Windows pela primeira vez, o Windows Defender Firewall bloqueia todo o tráfego de entrada não solicitado. Para permitir um certo tipo de tráfego de entrada não solicitado, você deve criar uma regra de entrada que descreva esse tráfego. Regras de saída O Windows Defender Firewall permite todo o tráfego de saída, a menos que uma regra o bloqueie. As regras de saída permitem ou negam explicitamente o tráfego originário de um computador que corresponda aos critérios de uma regra. https://learn.microsoft.com/pt-br/training/modules/explore-microsoft-defender/6-explain-windows-defender-firewall-advanced-security

ICMP Inbound is the correct answer! :)

I first thought its outbound role to response to ping requests but i was wrong. Given ans is correct. See here - https://kb.iu.edu/d/aopy or https://www.howtogeek.com/howto/windows-vista/allow-pings-icmp-echo-request-through-your-windows-vista-firewall/
