Huawei HCIE-Routing&Switching (Written)(Huawei Certified ICT Expert-Routing & Switching) Sample Questions:
Question 1
Which of the following description is wrong about the VPNv4 address?
A. The VPNv4 address has a total of 12 bytes, including an 8-word route identifier RD (Route Distinguisher) and a 4-byte IPv4 address prefix.
B. By default, the PE does not perform vpn-target filtering on the received VPNv4 routes.
C. Before the local PE advertises the VPNv4 route learned from the site directly connected to itself to other PEs, it sets the Target attribute for these routes and advertises it as a BGP extended community attribute along with the route.
D. When BGP advertises reachable and unreachable VPNv4 routes, it carries the RD attribute.

A. False
B. True
Question 4
If you run PIM-SM on a multicast network, you need to construct a multicast forwarding tree between the multicast source and the receiver for the receiver to receive multicast data, so the following descriptions are about the constructed multicast forwarding tree, which are the correct options? (Multiple Choice)
A. The SPT tree is constructed between the RP and the receiver.
B. The RTP tree is constructed between the RP and the receiver.
C. The SPT tree is constructed between the multicast source and the RP.
D. The RPT tree is constructed between the multicast source and the RP.
Question 5
If there is no zoning, which of the following statements are correct about the link state routing protocol? (Multiple Choice)
A. Each router learns routing entries from the updated routing information and adds them to the routing table.
B. Each router establishes a routing domain topology.
C. Routers in the entire routing domain have the same LSDB
D. The router sends all link state information from the neighbor to all other neighbors to ensure that the data in the database is synchronized.
E. Routers in the same routing domain may repeatedly receive the same link state information.
