Actual exam question from Microsoft's 70-741

Question #: 115
Topic #: 1

You are implementing a new network. The network contains a DHCP server named DHCP1 that runs Windows Server 2016. DHCP1 contains a scope named
Scope1 for the 192.168.0/24 subnet.
Your company has the following policy for allocating IP addresses:
✑ All server addresses must be excluded from DHCP scopes
✑ All client computers must receive IP addresses from Scope1
✑ All Windows servers must have IP addresses in the range of 192.168.0.200 to 192.168.0.240
✑ All other network devices must have IP addresses in the range of 192.168.0.180 to 192.168.0.199
You deploy a print device named Print1.
You need to ensure that Print1 adheres to the policy for allocating IP addresses.
Which command should you use?

A. Add-DhcpServerv4Lease
B. Add-DhcpServerv4ExclusionRange
C. Add-DhcpServerv4Filter
D. Add-DhcpServerv4Reservation

I disagree with the discussion here ... and agree with given answer D. Question states that only Servers need to be in the exlusion range. It also states that "other devices" must have an ip from x.180 - x.199 It does NOT state that clients musst have a address below x.180 So a client with x.185 would be ok. So you only have to make sure the print1 gets an ip adress x.180-x.199 So just add a reservation for the MAC-address of print1 and your ready to go.

Correct Answer: D Explanation: Use Add-DhcpServerv4Reservation to create a reservation for Print1, pick an IP address from range 192.168.0.180 to 192.168.0.199, for example:- Add-DhcpServerv4Reservation -ScopeId 192.168.0.0 -IPAddress 192.68.0.180 -ClientId "F0-DE-F1-7A-00-5E" -Description "Reservation for Print1"

Indeed. The setup here would have a scope with two exclusions. To give a device an IP in one of the excluded ranges would require a reservation.

I was all set to argue in favor of B until I re-read the part about Print1. It definitely helps to make sure you've read the whole question. Don't be like me, folks.

I think D is correct. When you exclude a IP addresses on a scope, DHCP doesn't lease the IP addresses, and you can set the IP manually. When you reserver the IP, DHCP can lease the IP, and you can't set the IP manually. This question says that the policy for allocation IP addresses. Therefore reservation (D) is correct.

I think D is correct. The policies for the print device are as follow. 1)It must get IP for other network devices. 2)It must get IP by DHCP. To solve them you must use reservation(D) so that it can use DHCP and IP address for other network devices. When it must get IP for servers, you must use exclusion(B), which doesn't use DHCP. If it must get IP for servers with DHCP, you don't have no answer in this question.

Aye - answer is correct. You don't want to start setting network printers up with automatically assigned addresses. You either want to set them up with a static IP, or configure a reservation for them - which means the answer here will be D.

Sorry, forgot to add. We have to assume that the printer is one of the 'other network devices', seeing as the servers are taking up a large chunk of the exclusion range, we would then create a reservation for the printer in the 'other device' range. Nowhere in the question does it state about having a new exclusion range for anything else. I mean, setting up another exclusion range WOULD work, but then you would need to create a reservation for it in the new exclusion range anyway lol, or give it a static IP.

thats incorrect that last bit . was tired when i wrote that. you would not need to set up a reservation in an exclusion range. kinda defeats the object!

1. Exclusions are useful for addresses that don't want to participate in DHCP at all eg Servers 2. Reservations are helpful for situations in which you want a client to get the same settings each time they obtain an address eg Particular device like printer

- All Windows servers must be in this range: 192.168.0.200 to 192.168.0.240 (you can make an exclusion from DHCP for that) - All other network and printer must be in this range: 192.168.0.180 to 192.168.0.199 (If you don't reserve an ip for the printer, the printer will receive an IP from DHCP between 192.168.0.1 to 192.168.0.199... so printer doesn't adheres to the policy) if you reserve the ip for the printer, printer adheres to the policy 100%. so answer is: D. Add-DhcpServerv4Reservation PS: Add-DhcpServerv4Lease cmdlet is only supported for DHCP server service that runs on Windows Server® 2012

Answer is D.......................Guys printers on a real network get assigned a static or reserved address for management reasons, and also its efficient for the print driver to use a static TCP/IP socket.

The answer is D. In the question it mentioning "All other network devices must have IP addresses in the range of 192.168.0.180 to 192.168.0.199". The printer is part of the other Device. In this case, the printer will obtain a IP address from the DHCP. You will need to find out the MAC address of the network printer to run the command line: ps:> Add-DhcpServerv4Reservation -ScopeId 192.168.0.0 -IPAddress 192.168.0.200 -ClientId "F0-DE-F1-7A-00-5E" -Description "Reservation for Printer" https://docs.microsoft.com/en-us/powershell/module/dhcpserver/add-dhcpserverv4reservation?view=win10-ps To find out your DHCP ScopeID: Get-DhcpServerv4Scope

"DHCP1 contains a scope named Scope1 for the 192.168.0/24 subnet." 192.168.0.1 - 192.168.0.254 IP lease Exclusion Range for x.180 - x.199 (Other Network devices) exclusion range for x.200 - x.240 (Servers) All clients obtain ip address between 192.168.0.1 - 192.168.0.179. Without reservation printer will obtain next address. YOU NEED RESERVATION BECAUSE QUESTION WANT x.180 - x.199

Answer B. You must create exclusion range because of that All other network devices must have IP addresses in the range of 192.168.0.180 to 192.168.0.199.

"The excluded IP addresses are not leased out by the Dynamic Host Configuration Protocol (DHCP) server service to any DHCP client. The only exception to this is reservation. If an IP address is reserved, the same IP address is leased to the designated client even if it falls in the exclusion range."
