Question

Which wildcard mask would be used to advertise the 192.168.5.0/27 network as part of an OSPF configuration?

O A. 0.0.0.31
O B. 0.0.0.3
O C. 0.0.0.255
O D. 0.0.0.15

Answer 1

The wildcard mask for a 192.168.5.0/27 network in OSPF configuration is 0.0.0.31, indicating that the last 5 bits of the address can vary.

Step-by-step explanation:

The wildcard mask that would be used to advertise the 192.168.5.0/27 network as part of an OSPF configuration is 0.0.0.31. A wildcard mask is used in networking to specify which bits of an IP address should be considered for matching, with '0's indicating bits that must match and '1's indicating bits that can vary. In this case, a /27 subnet has 32 IP addresses, meaning the last 5 bits of the address can vary, which corresponds to the binary value 00011111. Converting this to decimal gives us the wildcard mask of 0.0.0.31.
