R1, R2, R3, and R4 run IS-IS, and the DIS priorities of their interfaces are shown in the following figure. If all these devices are started simultaneously, will be elected as the DIS. (Enter the device name, for example, R1.)

Correct Answer:

R4
* DIS Election in IS-IS:
* In IS-IS, the Designated Intermediate System (DIS) is elected on broadcast networks to reduce the number of LSAs exchanged and maintain the LSDB.
* The DIS is elected based on priority:
* The router with the highest priority is elected as the DIS.
* If priorities are equal, the System ID is used as a tie-breaker, and the router with the highest System ID becomes the DIS.
* HCIP-Datacom-Core Technology Training Material (IS-IS DIS Election Mechanism).
Given DIS Priorities:
R1: Priority = 10
R2: Priority = 20
R3: Priority = 30
R4: Priority = 40
R4 has the highest DIS priority of 40, which makes it the clear choice for DIS election.
Scenario Details:
Since all devices are started simultaneously, the DIS election process will follow the priorities without requiring a tie-breaker (System ID).
Conclusion:
The device with the highest DIS priority is R4, and it will be elected as the DIS.
