Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Router 1.1.1.1 is the Designated Router on this segment.

  Why it's wrong here

  In a broadcast multi-access network, the Designated Router is the router that forms full adjacencies with all other routers on the segment. The output identifies the DR as 192.168.1.2, whereas the neighbor with router ID 1.1.1.1 has the interface address 192.168.1.1. Therefore, asserting that 1.1.1.1 is the DR directly contradicts the DR field in the neighbor table, so this option is incorrect.

• ✓

  Router 1.1.1.1 is the Backup Designated Router.

  Why this is correct

  The neighbor entry shows that 1.1.1.1 has an interface address of 192.168.1.1 and is in the FULL state. On the same line, the BDR field lists 192.168.1.1, which means this neighbor occupies the Backup Designated Router role for this multi-access segment. Because the BDR is the router that takes over if the DR fails, and the output explicitly assigns that address to this router, it is correct to conclude that 1.1.1.1 is the BDR.

• ✗

  The neighbor state is 2WAY.

  Why it's wrong here

  The neighbor state in the output is FULL, not 2WAY. The 2WAY state merely confirms that two routers can communicate bidirectionally, but it is not a state where full adjacency exists. Since the neighbor is a BDR, OSPF establishes a full adjacency with it, meaning the state must be FULL, as shown; therefore the claim of 2WAY is unsupported by the output.

• ✗

  The dead timer is 40 seconds.

  Why it's wrong here

  The output shows a dead timer of 34 seconds, which is the time remaining before the router considers the neighbor dead, not the configured OSPF dead interval. While the default dead interval on broadcast networks is often 40 seconds (four times the 10-second hello), the displayed value is the real-time countdown. Thus asserting that the dead timer is 40 seconds confuses the configured interval with the current remaining time, making the statement incorrect.
