An administrator is configuring single-area OSPF on a router. One of the networks that must be advertised is 192.168.0.0 255.255.252.0. What wildcard mask would the administrator use in the OSPF network statement?
- 0.0.0.127
- 0.0.0.31
- 0.0.3.255
- 0.0.0.63
Explanation: To determine the correct wildcard mask for an OSPF network statement, you subtract the subnet mask from 255.255.255.255. In this scenario, subtracting the subnet mask of 255.255.252.0 from 255.255.255.255 results in 0.0.3.255.
