Demo Questions
Question 1
About the OSPF calculating the shortest path tree phase, which of the following description is true?
- A: Stub network segment is calculated in the first stage, router node and transit network segment arecalculated in the second stage
- B: The routing node and Transiti network segment are calculated in the first stage, Stub network segmentis calculated in the second stage
- C: The Stub segment is calculated in the first stage, the routing node is calculated in the second stage
- D: The routing node is calculated in the first stage, the stub network segment is calculated in the secondstage
Question 2
About the description of IGMP Snooping working mechanism, which of the following statement is true?
- A: The Layer 2 switch establishes and maintains the PIM routing table at Layer 2 by continuously monitoring IGMP messages
- B: When IGMP Snooping is not running, multicast messages will be broadcast on the layer 2. After IGMP Snooping is running, the messages will no longer be broadcast on the layer 2, but will be multicast on the layer 2.
- C: If the host sends an IGMP leave message, the switch will add the host to the corresponding multicast table
- D: If a host sends an IGMP host report message, the switch will delete the multicast entry corresponding to the host
Question 3
How many Bytes is the minimum total length of the address in IS-IS?
- A: 2
- B: 8
- C: 20
- D: 16
Question 4
On the VRP platform, when we introduce OSPF routing to ISIS, if COST is not specified, the cost value will be set to 16.
- A: True
- B: False
Question 5
BGPAS_PATH property is a selectable transition property.
- A: True
- B: False
Question 6
Four routers are running IS-S and the adjacency relation has been established, and the level of area number and router are marked as shown, which of the following statements are true?
- A: Both R2 and R3 will have the Level-1's LSP of ATT set
- B: R1 does not have the LSP generated by R4, so R1 can only communicate with R4 through the default route
- C: Both R2 and R3 will have the Level-1's LSP of ATT set
- D: R2 and R3 learn default routes from each other, and there is a routing loop in this network

- B: The packet with source address of 1.1.1.3 matches the third ACL statement rule 2, and the matching rule is deny.
- C: The data packet with the source address of 1.1.1.4 matches the fourth ACL statement rule 3, and the matching rule is allow.
- D: The packet with the source address of 1.1.1.2 matches the second ACL statement rule 1, and the matching rule is allow
Question 9

- A: R1 and R2 can establish adjacency, but cannot complete routing calculations
- B: R1 and R2 can establish adjacency and can complete routing calculations
- C: R1 and 2 cannot establish adjacency, because the network type of the interface is not consistent
- D: R1 and R2 cannot establish adjacency, because OSPF process ID is not consistent
