Did you typo above? 184-191, with 185-190 usable.
Answer: C
C 7
Selected Answer: C
Simple way to view it:
/29 = 8 IPs, 182-191, 190 is the last Assignable IP on that Subnet, so /29 is chosen because it is the Longest Prefix route INCLUSIVE of the IP address. And the next hop IP for that is C. 192.168.7.35

Leaving out all the description about load-balancing traffic, etc etc... the bottom line is what is the next hop of address 172.16.1.190? Answer is C.192.168.7.35.
How I got it?
/29 subnet(/32 minus /29 equals to 3 subnet bits)
Now take 2 to the power of 3 youll have 8 subnets and for host just minus 2 which is 6 hosts(for network & broadcast subnet ID, ITS A MUST)
So, in the network address 172.16.1.184....starting address is 172.16.1.185 all the way to 172.16.1.191 thus the 172.16.1.190 host is able to be allocated to this network ID(172.16.1.184). That's how you'll get your answer. Good Luck to all.
