| Hello!
I hope your Monday is half as crazy as mine!
Here's today's question:
Business has started picking up and the time is right to expand. You must use all IP addressing before requestlng more from HQ (Don't you love corporate policies?!?). You only have two networks, 192.168.72.208 /28 and 192.168.72.224 /27, but must connect 3 new sites with numbered P2P circuits, and each site has 3 people and a server in addition to the router (growth is not a factor for this exercise).
Bonus: How many subnets will be left?
Here's the 6/5 question with answer (okay, at least one possible answer:
You have been asked to provide the IP adressing for the new Disaster Recovery site. You have been given 12.27.146.0 /24 from DR Facility Manager, and need to create an Internet DMZ with 20 hosts, a VPN DMZ with 10 hosts, a B2B DMZ with 11 hosts, and a production network with 112 hosts.
Reqs:
10 host net (B2B DMZ)
20 host net (VPN DMZ)
112 host net (Prod)
/25= 126 hosts (did you get that you needed IP Subnet-zero?)
/27= 30 hosts
/28= 14 hosts
B2B DMZ = 12.27.146.16 /28
VPN DMZ = 12.27.146.32 /27
Production net = 12.27.146.128 /25
Bonus - Available for growth: 12.27.146.64 /26
The "Bonus" was provided for info only - it is above the scope of the CCNA exam, but it will be helpful in the real world.
