Answer: 
192.168.10.25
210
Can you explain why you think this is the right answer, rather than just putting it down here? Here is what I think is the right answer:
192.168.15.250 – The computer with the MAC address is trying to connect to the network 192.168.15:- which has the DNS server attached 192.168.15.250, which comes from the command Set-DhcpServerv4Optionvalue -DnsServer 192.168.15.250 -Router 192.168.15.1 -ScopeId 192.168.15.0. The reservation on the MAC address is for the 192.168.10 network.
210 – A little bit of simple math here to find out the number of available addresses. The server scope is adjusted so the range is from 11 to 230. Including the border numbers, that is 220 available addresses. The exclusion command then excludes the addresses 21 to 30, which is a total of 10 addresses (including the borders).
Thus, 220 – 10 = 210 available addresses.
the question is tricky
192.168.15.250 because PC with mac: AABBCCDDEEFF connects to 192.168.15.0/24 subnet but reservation is on the different subnet 192.168.10.0/24
Scope and exclusion ranges include borders, so:
11 to 230 = 220 addresses
21 to 30 = 10 addresses
220 – 10 = 210
Disagree gents.
DNS server is set to 172.16.1.250 for the reserved IP of 192.168.10.15

EXAMPLE 3
This example sets the option values for DNS server, WINS server, DNS domain, router, and WPAD for reserved IP address 10.10.10.5.
Windows PowerShell
PS C:\> Set-DhcpServerv4OptionValue -ComputerName dhcpserver.contoso.com -ReservedIP 10.10.10.5 -DnsServer 192.168.1.2 -WinsServer 192.168.1.3 -DnsDomain contoso.com -Router 192.168.1.1 -Wpad http://proxy.contoso.com/wpad.dat
I think the answer is right.
There is two scopes configured on the server. The reservation is set on the first scope, 192.168.10 and the DNS Server 172.16.1.250 is set for the reserved IP 192.168.10.15, which is a reservation in scope id 192.168.10
The question is what would IP address the client that has MAC AABBCCDDEEFF will get when this client is connected to a network segment that requests an IP address from Scope “192.168.15”?
The answer is that it will get an IP address from “192.168.15” scope and the DHCP options, including the DNS server configured for “192.168.15” scope. The DNS server configured for “192.168.15” scope is 192.168.15.250
So the answer is correct, DNS server 192.168.15.250
Wouldn’t the number of leases available actually be 254 instead of 210?
The subnet listed is the /24 subnet.
11111111.11111111.11111111.00000000 = 255.255.255.0
2^8=256-2=254
no thats the potential number of leases available, not the number of addresses set by the commands shown
