Question 550
Two OSPFv2 routers on shared Ethernet Gi0/3 use the same IPv4 subnet, area, and timers. R1 enables message-digest authentication but R2 is configured for no authentication. What is the targeted fix?
Explanation
Correct Answer

That explanation does not distinguish this option. “Enable DHCP snooping on an unrelated VLAN 150” is an alternative action, but it does not by itself establish the outcome required in this case.
