You want to make sure that key business in the network HW get high priority. 
which field does IP Precedence of data packets based on to set? 
A. All the 8 bit of ToS field 
B. the first 4, 5 and 6 bit in ToS field 
C. three least significant bits in ToS field 
D. three most significant bits in ToS field 
Answer: D

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

A running OSPF router is connected to Area 0 and Area 1. You will configure Area 1 to stub area. 
which kind does LSA only in the Area 1 internal operate? 
A. Class 7 LSA 
B. Class 1 LSA and Class 2 LSA 
C. Class 1 LSA,Class 2 LSA and Class 5 LSA 
D. Class 3 LSA and Class 4 LSA 
E. Class 1 LSA, Class 2 LSA and Class 3 LSA 
Answer: E

Which of the following information does STP based on to calculate path cost? 
A. interface bandwidth 
B. interface delay 
C. interface bandwidth and delay 
D. hops 
E. bridge priority 
Answer: A

The SPF algorithm, which of the following description is correct? (Multiple choice) 
A. SPF algorithm also called Djkstra algorithm 
B. SPF algorithm only uses in the first time to calculate the shortest path tree 
C. When router calculate the shortest path tree, with itself as the root to build SPF tree 
D. when router calculate the shortest path tree, with its target segment as the root to build SPF tree 
E. HW router default OSPF reference bandwidth is 10^9/BW 
Answer: ABC

To configure AAA, you first need to define the RADIUS server, RADIUS server defined manner as follows: 
[Huawei] radius-server template EXAM

[Huawei-radius-EXAM] radius-server authentication 10.7.66.66 1812 
[Huawei-radius-EXAM] radius-server authorization 10.7.66.66 1812 
[Huawei-radius-EXAM] radius-server accounting 10.7.66.66 1813 
[Huawei-radius-EXAM] radius-server retransmit 2 
A. True 
B. False 
Answer: B

When MPLS network carrying IP packets, TTL will be how to deal with? (Please choose 2 correct answers) 
A. MPLS label head TTL is set to 255 
B. In the direction of the boundary of LSR, IP packet TTL is copied into the TTL field of MPLS 
C. MPLS label header TTL is set to 0 
D. In the direction of the boundary of LSR to disable the TTL 
E. In the MPLS domain, TTL can not be disabled
