最新的 JNCIS-ENT JN0-351 免費考試真題 (Q88-Q93):

問題 #88
Exhibit

Referring to the exhibit, which statement is correct?

答案：B

解題說明：
In a Rapid Spanning Tree Protocol (RSTP) topology, the root bridge is determined by the switch with the lowest bridge priority value 1 2 . If all switches have the same priority, then the root bridge is assigned to the switch whose MAC address's hex value is the lowest 2 . The default bridge priority value is 32768 3 2 .
However, without the actual exhibit, it's difficult to definitively determine which device is the root bridge. But based on the options provided, if we assume that the local device has a lower bridge priority or a lower MAC address than other devices in the network, then it could be considered as the root bridge for this RSTP topology 4 5 .


問題 #89
Which statement is correct about GRE tunnels?

答案：B


問題 #90
Exhibit.

Why is this OSPF adjacency remaining in this state?

答案：A

解題說明：
The exhibit shows the output of the command , which displays information about the OSPF neighbors on a router1.
The output shows that the OSPF neighbor with the address 172.26.1.1 and the interface ge-0/0/3.0 is in the Exstart state1.
The Exstart state is the fourth state in the OSPF neighbor formation process, after Down, Init, and
2-Way states2. In this state, the OSPF neighbors establish a master-slave relationship and exchange database description (DBD) packets, which contain summaries of their link-state databases2.
The most common reason for OSPF neighbors to be stuck in the Exstart state is an MTU mismatch between the interfaces3. MTU stands for maximum transmission unit, which is the largest size of a packet that can be transmitted on a network segment4. If the MTU values of two OSPF neighbors are different, theymay not be able to exchange DBD packets successfully, as some packets may be dropped or fragmented due to their size exceeding the MTU limit3.
To solve this problem, you need to ensure that the MTU values of both OSPF neighbors are the same or compatible. You can use the command show interfaces to display the MTU value of an interface5. You can also use the command ping with the do-not-fragment option to test the MTU size between two routers. You can change the MTU value of an interface by using the command set interfaces interface-name mtu mtu-value in configuration mode5.


問題 #91
Referring to the exhibit, the local router should have an IS-IS adjacency with a neighboring router, but the adjacency never establishes correctly.

What should you do to solve the problem?

答案：A


問題 #92
You want to prevent rogue BPDUs from lab devices reaching the internal through the Lab_Switch device.

Referring to the exhibit, what should be done to accomplish this task?

答案：C


問題 #93
