Refer to the exhibit. Examine the partial configuration and the routing table excerpt. Which
routes would be redistributed into OSPF area 1?
Select the best response.
A.
10.10.10.16/28 only
B.
10.10.10.16/28 and 10.10.10.64/26
C.
10.10.10.16/28, 10.10.10.64/26, and 172.16.10.0/24
D.
10.10.10.64/26 only
The answer should be B, I just labbed this up.
10.10.10.16/28 is in the EIGRP topology table because of the network command, so it will be advertised.

Nice one Brian!
While in real world you would be correct, in cisco exams, a rather special rules and laws exist 🙂 as you can see, the 10.10.10.16/28 in exhibition is labeled as C, where as in the real world that would not be the case, so just watch out for tricks like that 🙂
So what are you trying to say.
I did it, and I had the same result as Brian
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.10.0 is directly connected, FastEthernet0/1
10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
O E2 10.10.10.16/28 [110/20] via 172.16.10.1, 00:00:00, FastEthernet0/1
O E2 10.10.10.64/26 [110/20] via 172.16.10.1, 00:00:00, FastEthernet0/1
