Exam 70-741 topic 1 question 66 discussion

In my opinion, filter cannot be used because it is used to prevent clients on server level, but this question is saying to prevent clients on scope level. So, the only option is DHCP policy. Answer is C

https://blogs.technet.microsoft.com/teamdhcp/2012/09/15/scope-level-link-layer-filtering-using-dhcp-policies-in-windows-server-2012/ The question mentions that you have a scope for 75 computers, but doesn't say it's the only scope on the server. The question states that you need to make it so only those 75 systems can get an IP from that "scope" not from the server as a whole. Using a policy on the scope can accomplish this while still allowing the rest of the server to function normally.

You can create a filter on the scope, but the option presented is to create a DHCP Filter so we have to assume it was meant for the entire server, not just the scope. The question is asking you to limit unknowns MACs from getting an IP only from the scope, which is why we create the Scope policy.

Filters can't be applied to scopes. Policies can.

I think that C is correct. My understands are follow. Since C says "a DHCP policy for the scope", it apply for only one scope. Since B says "a DHCP filter", it apply for a DHCP server, which is a group of scopes.

The answer is C without a doubt. Why? Filters are SERVER level. The question clearly defines 'scope'. You cannot set Filters on a scope level, but you CAN set policies on a scope level. C is correct

C is correct. You must use a DHCP Policy for the Scope. You can specify MAC address as a condition in the scope. If you apply a DHCP Filter it will apply to the whole server and ALL scopes. This question is about restricting access to one scope.

C. Create a DHCP policy for the scope.

You should configure a DHCP policy "if" condition, based on the MAC addresses of all clients. Using the "AND" operator selected, adding them in the policy list.

Key thing is what Microsoft wants from us with these question...we would have to try this in a lab..

The question states: You need to ensure that only the 75 Windows 10 computers can obtain a lease from the scope. A filter won't do the job unless you enter 75 mac addresses from the Window 10 computers. You need a policy specing control by the 75 - Windows 10 OS.

there are only 75 Computer, we can can use the filter to filter the MAC address, so I think B is correct answer https://www.dtonias.com/configure-dhcp-server-2016-filters/

noppy is right, can not read anything into the question except what is given.

This type of question continues to confuse me. In my home lab, I am able to filter by mac address using either a policy, or a filter. both seem to work. I am not sure the version of OS will even matter, both filter and a policy will use the mac addresses to filter on as a condition.

You have to use a DHCP Filter (on the server level). DHCP policies are only used for providing options for a set of devices based on specified conditions (server or scope level). https://docs.microsoft.com/en-us/powershell/module/dhcpserver/set-dhcpserverv4policy?view=win10-ps https://docs.microsoft.com/en-us/powershell/module/dhcpserver/add-dhcpserverv4filter?view=win10-ps
