Huawei HCIE-Carrier IP (Written) Sample Questions:
As shown in the figure. CE 1 and CE 3 belong to VPN-A, and CE 2 CE 2 4 belong to VPN-B VPN-target VPN-A is 111:1 and that of VPN-B is 222:2 users on different VPNs are not allowed to access each other. Configuration principles are as follows:
On the backbone network VPNs are not connected to a CE, VPN instance need to be configured on the PE, and an interface on the PE for connecting to the CE must be bounded to a VPN instance. After binding an interface to a VPN instance, you must configure the IP address of the interface Between PEs, IS-IS is configured for PE interworking. MPLS basic capabilities and MPLS LDP are configured for MPLS LSP establishment, and MP-IBGP is configured for VPN route exchange.
How to enable CE 1 to learn routes from AS 64430?
- A. Import BGP routes in IS-IS process 200
- B. Import BGP routes in IS-IS process 100
- C. Import IS-IS 100 routes in IS-IS process 100
- D. Import IS-IS 200 routes in IS-IS process 100
Correct Answer: B 🗳️

- A. No strict requirement
- B. Bearer network delay variation +100 ms, allowed maximum delay variation +200 ms
- C. Bearer network delay variation = 10 ms. Allowed maximum delay variation =20ms

As shown in the figure, RTA, RTB, and RTC use the OSPF protocol. The default cost value is used for links, and unicast routes converge on the entire network. The Loopback 0 interface is set to configure RTC as the RP or BSR. The SPT switching threshold uses the default value on RTB. The receiver joins the multicast group 225.1.1.1. The multicast source sends multicast data to the destination address 225.1.1.1. Which interface is the inbound interface in the (10.1.1.1, 225.1.1.1) entry on RTB?
- A. Ethernet 1/0/1
- B. Ethernet 2/0/0
- C. Ethernet 1/0/0
- D. Null
Correct Answer: C 🗳️
About the merits and demerits of inter-AS VPN-IPv4 Option B using MP-EBGP between ASBRs, which statement is true?
- A. An ASBR is required to store all VPN routes, which challenges the performance of the ASBR.
- B. The inter-AS scheme in Option B is an inherent feature of VPN.
- C. An ASBR does not store VPN routes but sends them out as label data.
- D. VRFs matching PEs must be configured on the ASBR.
Correct Answer: A 🗳️
