Question 19 the answer is wrong
wildcard mask should be 0.0.255.255 (inverse of /16), answer 1 is the correct one
correction regarding first reply.. after looking into the netacad course again, the course mentions that some cisco IOS versions translate the subnetmask into a wildcard mask. So if only the 172.16.1.0 network needs to be advertised, it would be a /24 network, therefore answer 3 is the correct one.
If answer 1 would be configured, it would implicate the networks 172.16.0.0 – 172.16.255.255 would be advertised.

Why the R3 router is BDR, if it has not configured ID and no configured a loopback
As I know, elections of a DR are based on the following in order of precedence:
R3 has an equal priority with R1 but its highest IP address is higher than IP address of loopback on R1
Thank you for explanation)
