The router's interface IP is 192.168.0.100/24 # which belongs to the subnet 192.168.0.0-192.168.0.255.
However, 192.168.0.100 is already assigned to the router. So, this IP must be excluded from the DHCP pool to avoid conflicts.
* C offers two valid ranges excluding .100:# 192.168.0.1-192.168.0.99# 192.168.0.101-192.168.0.254 Let's evaluate other options:
* A. 192.168.0.1-192.168.0.255 ##Includes broadcast (.255) and router IP (.100) # Invalid
* B. 192.169.0.1-192.169.0.254 ##Completely wrong subnet
* D. 192.168.0.1-192.168.0.14 ##Valid but unnecessarily small
MTCNA DHCP Chapter - Address Pools:
"Make sure the pool does not include the router's IP or the network's broadcast address. Common errors involve overlapping pools." Rene Meneses MTCNA Guide - DHCP Configuration:
"Exclude the router's own IP from the range. Use address pools below and above the assigned IP." Terry Combs Notes - DHCP Pool Tips:
"Split the pool to avoid assigning the interface IP to clients. Also avoid .0 and .255."
