Which of the following description about IBGP neighbor EBGP neighbor is true? (Multiple choice)
A. router will sent the BGP updates learning from its IBGP neighbor to their other IBGP neighbor and EBGP neighbor
B. router will sent the BGP updates learning from its EBGP neighbor to their other IBGP neighbor and EBGP neighbor
C. IBGP neighbor must be directly connected. Otherwise, IBGP-Multi-hop must be configured
D. EBGP neighbor must be directly connected. Otherwise, EBGP-Multi-hop must be configured

Answer: BDE
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
Answer: D
In shared network,Which mechanism is used by PIM-SM to prevent repeat traffic?
A. Register mechanism
B. BSR/RP mechanism
C. Assert mechanism
D. Join/Prune mechanism
Answer: C

C. OSPF stub area allows route redistribution, but totally stub area does not allow importing routes
D. When the route is introduced into the OSPF complete stub area, the route entries will turn to Class five LSA
E. When the route is introduced into the OSPF complete stub area, the route entries will turn to Class Seven LSA
Answer: E

A. switch and terminal by 10/100/1000Base-T Ethernet link connected, and the working mode of the switch and terminal is half duplex
B. in most of the environment all have such False
C. working mode on 1000Base-LX/LH link don't match

Answer: D
You're troubleshooting frame relay interface serial 0 on HW router. When the interface is up and quickly enters the down state. You use the command display interface, see LMI status message of interface serial has been sent but not received.
So what causes the problem occur?
A. Receive too much error message on the link
B. Frame Relay Imi-type configuration error
C. Subinterface number exceeds the limits of the IDB
D. DCD configuration errors on the frame relay line
E. Ends of keepalive configuration error
Answer: B
A company from a carrier rented a 1Mbps CIR frame relay special line, recent stability is not good, frequent oscillation, network administrators found in the configuration of router parameters forgot to configure CIR parameters, after fixing the problem, the line will restore stability.
A. True
B. False
Answer: B
To configure AAA, you first need to define the RADIUS server, RADIUS server defined manner as follows:
