Question 1 of 107
Exam JN0-351: Question 1 - Image 1
Referring to the exhibit, which router will become the OSPF BDR if all routers are powered on at the same time?
Answer

Suggested Answer

The suggested answer is C.

In OSPF, the election of the Backup Designated Router (BDR) is determined by priority first, and in case of a tie, the Router ID (RID). R1 is excluded from becoming either the DR or BDR since its priority is set to 0. This leaves R2, R3, and R4 in consideration. R2 has a priority of 100, which is lower than the priority of R3 and R4 (both 128). Between R3 and R4, both having the same highest priority, the router with the highest RID will become the Designated Router (DR). R4 has a higher RID (10.10.10.4) than R3 (10.10.10.3), so R4 becomes the DR and R3 becomes the BDR.

Answer

Suggested Answer

The suggested answer is B, C.

BFD (Bidirectional Forwarding Detection) is typically used with routing protocols to ensure rapid detection of faults. Among the given options, BGP and OSPF are known to support BFD for expedited fault detection. RSTP (Rapid Spanning Tree Protocol), LACP (Link Aggregation Control Protocol), and FTP (File Transfer Protocol) do not support BFD.

Question 4 of 107
Which statement is correct about graceful Routing Engine switchover (GRES)?
Answer

Suggested Answer

The suggested answer is C.

When combined with Nonstop Routing (NSR), graceful Routing Engine switchover (GRES) ensures that routing information is preserved and the new master Routing Engine does not need to restart the Routing Protocol Daemon (rpd). This allows for minimal disruption in network operations during a switch.
