Huawei HCIP-Datacom-Advanced Routing & Switching Technology V1.0 Sample Questions:
Question 1
On a BGP/MPLS IP VPN network, VPNv4 routes carry the export RT. Which of the following attributes is used by MP-BGP to carry the export RT?
A. Extended_Community
MP_REACH_NLRI
B. Local_Preference
C. AS Path
Question 2
OSPFv3 packets are encapsulated in IPv6 packets and can be sent in unicast, multicast, or broadcast mode.
A. TRUE
B. FALSE
Question 3
On the OSPF network shown in the figure, the cost values of links are marked, and OSPF IP FRR is enabled on R1. Which of the following statements is false?
A. If the link between R1 and SI is disconnected and you check neighbor information on R1, the neighbor relationship between R1 and R2 will instantly display Down.
B. If the link between R2 and SI is disconnected, R1 recalculates the optimal path to R3 and performs path switching instantly.
C. If the link between R1 and SI is disconnected, Rl recalculates the optimal path to R3 and performs path switching instantly.
D. If the link between R1 and SI is disconnected, R1 directly uses the backup path to forward packets to R3 because FRR is enabled on R1.
Question 4
On an enterprise network shown in the figure, if CE2 is dual-homed to PE2 and PE3 , a routing loop may occur during the exchange of Type 5 LSAs (External LSAs in OSPF) .
To prevent the loop, the route-tag command can be run on PE2 and PE3 .
In this way, if the route tag of the route received by PE3 is the same as that configured locally, the route is ignored.
Is this statement True or False?
A. TRUE
B. FALSE
Question 5
To support the processing and calculation of IPv6 routes, IS-IS adds a new NLPID to TLV 129. The NLPID is an 8-bit field that identifies network layer protocol packets. Which of the following is the NLPID of IPv6?
A. 204
B. 142
C. 232
D. 236
