A.
2. network 172.16.0.0
auto-summary
B.

E.
1. ip route 172.0.0.0 255.0.0.0 172.16.1.1
F.
2. aggregate-address 172.0.0.9 mask 255.0.0.0
Explanation:
1. 1 E, conditional static route disappears when the link to 172.16.1.1 disappears
2. 2B, correct network command, correct mask, will not advertise when link goes down.Wrong answer
1. A wrong mask need /8 this defaults to /16
2. C This is unconditional
3. D This is an unconditional floating static route
4. F should be 172.0.0.0 not 172.0.0.9
