Question 1110
Lighthouse Medical needs to set an OSPF router ID explicitly to avoid unexpected election. Which implementation directly addresses that objective without replacing it with a different network control?
Explanation
Correct Answer
An explicitly configured 32-bit router ID has priority over automatic loopback/interface selection. This is the control that implements the specified requirement.
Incorrect Answers
Cisco IOS marks configured static routes with S in show ip route. That is not sufficient here: An explicitly configured 32-bit router ID has priority over automatic loopback/interface selection.
Removing the static configuration affects that route, not the unrelated dynamic routing protocol. That is not sufficient here: An explicitly configured 32-bit router ID has priority over automatic loopback/interface selection.
A static route must resolve an eligible next hop or egress path to be usable. That is not sufficient here: An explicitly configured 32-bit router ID has priority over automatic loopback/interface selection.
