Exam 70-741 topic 1 question 122 discussion

Actual exam question from Microsoft's 70-741

Question #: 122
Topic #: 1

You are deploying a small network that has 30 client computers. The network uses the 192.168.1.0/24 address space. All computers obtain IP configurations from a DHCP server named Server1.
You install a server named Server2 that runs Windows Server 2016. Server2 has two network adapters named Internal and Internet. Internet connects to an
Internet Service Provider (ISP) and obtains the 131.107.0.10 IP address. Internal connects to the internal network and is configured to use the 192.168.1.250 IP address.
You need to provide Internet connectivity for the client computers.
What should you do?

A. On Server2, select the Internet and Internal network adapters and bridge the connections. From the DHCP console on Server1, authorize Server2.
B. On Server1, stop the DHCP server. On the Internal network adapter on Server 2, enable Internet Connection Sharing (ICS).
C. On Server2 run the New-NetNat Name NAT1 -InternalIPInterfaceAddressPrefix 192.168.1.0/24 cmdlet. Configure Server1 to provide the 003 Router option of 131.107.0.10.
D. Install the Routing role service on Server2 and configure the NAT routing protocol. Configure Server1 to provide the 003 Router option of 192.168.1.250.

Option D is correct. The clients need to get the information where to look for the new configured NAT server on the internal network. "Configure Server1 to provide the 003 Router option of 192.168.1.250."

D is correct answer because you need to provide router option that client computer can connect in which they will will 192.168.1.250 as a default gateway, the NAT will translate 192.168.1.250 to 131.107.0.10 which is the external IP address from the Service provider.

I think D is correct anwser. Common questions, including this quesiton are as follow. Net solution has two types method. 1)You use New-NetNAT**** cmdlet. >>Q152 in topic 1 2)You use RAS and NAT in RAS. >>Q122 in topic 1

Purely because this is a 70-741 question, and inside 70-741 we are supposed to know about NAT'ing... I am going with D. B does not seem viable, seeing as it stops the DHCP server. C provides the completely wrong gateway address. A is also a no.

D is correct. Option C is missing that the Routing role is needed for NAT and that the Default Gateway must on the Internal network for the clients.

The focus should especially be on the "default gateway being on the internal network for the clients.

"Server2 has two network adapters named Internal and Internet." indicates it is a good server for implementing NAT for clients behind it to access Internet. 250 NAT clients then must send packets to NAT Server's private interface 192.168.1.250 first, therefore Answer B - configuring 192.168.1.250 as all NAT client's default gateway address is correct.

ICS can provide NAT for clients behind it to access the Internet, but doesn't provide the features that the Routing role does. So the answer should be D.

Answer is D. It's not B since you'd have to stop the DHCP server and the clients need it. It's not C because the 003 Router option is the external address and it should be the internal one.

MS questions... bleh ICS will provide nat/dhcp(thats why we stop DHCP) https://docs.microsoft.com/en-us/troubleshoot/windows-server/networking/set-up-internet-connection-sharing This is less secure in my opinion, also less features So I go also with D, implement routing/nat

Ill correct myself, reading Topic 2 Question #4 , I noticed On the >>>>Internal network adapter<<<< on Server2 -> so if it would state on the "internet" adapter, then this would be a viable answer; So I yet again for D 'implement routing/nat' :)
