This is how I read it..
First Question is that the computer is connected to the 192.168.15.0 network , relay agents and network devices will ensure the computer gets a 192.168.15.xx address..
Second question
Creation of scope 2 – startrange 11 endrange 200 = 189
Reconfigure Scopeid 192.168.15.0 – startrange 11 endrange 230 = 219
Exclusion Scopeid 192.168.15.0 – startrange 21 endrange 30 = 9
219 -9 = 210

They say that the computer is not connected to network 192.168.10.x, but 192.168.15.x
7th code line:
Set-DhcpServerv4OptionValue -Dnsserver 192.168.15.150 -Router 192.168.15.1 -ScopeId 192.168.15.0

The 172. DNS is only for that reserved IP from the second line.
The 192 scope ID is what applied to all other addresses in that scope.

MAC Address AABBCCDDEEFF is from reserved IP 192.168.10.15
Set-DhcpServerv4OptionValue -DnsServer 172.16.1.250 -ReservedIP 192.168.10.15
from above, the DnsServer 172.16.1.250 is set for 192.168.10.15
Answer: 172.16.1.250
******************************************************************
Set-DhcpServerv4Scope -ScopeId 192.168.15.0 -StartRange 192.168.15.11 -EndRange 192.168.15.230
Scope range is 11-230 = 220
then an exclusion from 192.168.15.21 to 192.168.15.30 = 10
DHCP Scope for 192.168.15.0 is 220(range)-10(exclusion)
answer is 220-10 = 210 available addresses for lease
