There is a network composed by router R1, router R2, router R3 and router R4. The four routers are interconnected by a LAN network. All four routers deploy the basic OSPF. When you are executing the command „display ospf peer” on Router 2, you will find the status between Router2 and Router3 is „2-way”.
So from this output, what conclusion can you draw? (Multiple choice)
A. the router R2 is DR or BDR
B. router R3 is neither DR, nor the BDR
C. router did not form a full adjacency relationship between R2 and R3 router
D. router R2 is not DR
E. the router R4 is DR
auto-negotiation mode is to obtain maximum interface rate and the operating mode, the network administrator will set all Ethernet interface rate of a workgroup switch to 100Mbps, operating mode configured to full-duplex. When a NIC is configured to auto-negotiation of the workstation is connected to the switch, the outcome of consultations is that the interface rate is 100Mbps, the operating mode is half-duplex.
For this phenomenon, which of the following explanation is the most reasonable?
A. At higher port speed and operating mode, the workstation’s network interface card can¡¯t be configured to auto-negotiation
B. port rate negotiation consultations through the initial port to send FLP to negotiate, work mode does not negotiated by FLP
C. when STP in initialization will make the port enter the blocking state, leading to auto-negotiation fails, so the port should be configured to portfast
D. does not configure auto-negotiation on the switch, leading to the swtich can’t send the FLP information to the workstation, thereby causing the work station set its own oerating mode to haIf-duplex
E.problem lies in the workstation’s network card, most due to the workstation NIC drivers too old, leading to the interface on the workstation NIC learning rate and the operating mode switch configuration
Which of the follwing description about BSR/RP mechanism is true? (Multiple choice)
A. PIM-SM domain can have multiple C-BSR, but can only elect a BSR
B. BSR through the received C-RP data packet to collect C-RP information
C. BSR by flooding Bootstrap packets advertised BSR information and C-RP information to all router in PIM-SM domain
D. a C-BSR also can collect C-RP information through received C-RP data packets
What are the key component of NAC?
A. communication agent
B. NAC equipment

As shown, in the configuration of router R3 set ISIS overload bit , which of the following statement is True? (Multiple choice)
A. R3 starts overload state, R1 and R2 will not calculate the R3 generated LSP in SPF tree.
B. R3 LSP will not be able to spread to R1 and R2.
C. R3 direct route because of the overload bit set will be ignored by R1 and R2.
D. R3 imported routes through import-route will not be able to publish.
E. when router memory is insufficient, the system will automatically set the overload flag bit in sent LSP packets, it is irrelevant to whether the user configure the set-overload command.
