Refer to the exhibit. Router R4 is configured correctly with default OSPF values. A network engineer configured R7 for OSPF. R7 must not be elected as a DR for the segment between R4-R7. The adjacency between R4 and R7 failed to form. Which configuration resolves the issue?
To ensure that Router R7 is not elected as a DR, the OSPF priority must be set to 0, as a router with an OSPF priority of 0 is ineligible for the DR/BDR election. The configuration should also maintain the default OSPF hello and dead intervals (10 and 40 seconds respectively), which it does. Additionally, setting the network type to broadcast is appropriate for a FastEthernet network. Therefore, the correct configuration is to set the OSPF priority to 0, ensure the hello interval is 10, the dead interval is 40, and to set the network type to broadcast.
C is correct because the default value of OSPF hello and death interval are 10 and 40. ip ospf priority must be 0.
Answer: C "R7 must !! not !! be elected as a DR" -> A neighbor with priority 0 is considered ineligible for DR election. The default values are 10 seconds for the hello time, and 40 seconds for the dead time. The usual rule of thumb with OSPF is to keep the dead time value four times the hello interval. However, this is not a strict rule.
"R7 must !! not !! be elected as a DR" A neighbor with priority 0 is considered ineligible for DR election. So i agree with bk989 comment.
B makes more sense as a result
An OSPF priority of 0 keeps a router from being DR/BDR. Default priority is 1 and priority value of 255 makes. everything else about C is correct save for the priority value
What are the answers? The images are corrupted!!!
the only possibility is C or D as it sets ospf priority to 0. Then choose between broadcast or non-broadcast. fastethert interfaces are usually broadcast (by default) so if we do se it to non-broadcast then the other side better hopefully be non-broadcast also. And finally the timers 10 40 match for broadcast (assuming the other side is broadcast). However D would also work if the other side of the link didn't have default ospf fastethernet settings. Best answer is C.
