Question 390
An acceptance check at Copperline Studios has two requirements: (1) identify which router becomes the OSPF DR among two equal-priority routers, and (2) remove a stale configured IPv4 static route without altering newer dynamic routes. Select TWO actions that together satisfy both outcomes.
Explanation
Correct Answers
Correct for outcome (2): Removing the static configuration affects that route, not the unrelated dynamic routing protocol. It complements the first required control.
Correct for outcome (1): Higher router ID wins the DR election priority tie when both are otherwise eligible. The other outcome needs its separate action.
Incorrect Answers
Not selected: Give the backup static route AD higher than OSPF's 110 is for provide a static backup only if an OSPF route to the same prefix disappears. A floating static route loses normally but is installed when the preferred OSPF route is withdrawn. This is outside the two requested outcomes.
Not selected: Look for a route marked O in the IPv4 route table is for recognize a route learned through single-area OSPF in the routing table. Cisco IOS uses an O routing protocol code for ordinary OSPF intra-area routes. This does not provide either of the two specified controls.
Not selected: Configure passive-interface on the relevant OSPF interface is for prevent an interface from sending OSPF hello packets while still advertising its connected network. Passive interfaces suppress OSPF neighbor hello formation while eligible network prefixes remain advertised. This is not one of the two required changes.
