Huawei HCIP-Datacom-Campus Network Planning and Deployment V1.5 Sample Questions:

1. In an MPLS VPN network, which of the following descriptions best fits the role of a "P device"?

A) Only forwards packets carrying MPLS labels; does not maintain VPN routing information.
B) Maintain VPN instances and separate VPN routing tables
C) Directly connect the CE device and access the VPN user route.
D) Responsible for routing interactions between CE and PE.

2. In an MPLS VPN network, when a PE device receives a VPNv4 route advertised by another PE device, which of the following operations can "convert the route into an IPv4 route and advertise it to the local CE device"?

A) Configure routing policies on the PE device to export VPNv4 routes to a CE-PE routing protocol (such as OSPF).
B) Enable the MPLS protocol on the CE device to directly receive VPNv4 routes.
C) Configure route translation on the P device to convert VPNv4 routes to IPv4 routes.
D) No configuration required; PE devices automatically convert and advertise routes.

3. In troubleshooting MPLS VPN networks, which of the following tools or commands can help locate the "VPN routing failure" problem? (Multiple choice)

A) Display ip routing-table vpn -instance (to view the VPN instance routing table)
B) Lack of troubleshooting tools, relying on experience-based judgment
C) display mpls lsp (to view the MPLS label forwarding path)
D) Only check device CPU/memory usage, do not check routing and LSP.
E) Ping/ Tracer (test connectivity between CE and PE, and between PE and PE)

4. In a wide area network (WAN) IPv6 transition scenario, if "an enterprise has both IPv4 and IPv6 servers internally and needs to provide services using both protocols to the outside world," which of the following technologies should be used?

A) IPv6 over IPv4 tunnel (IPv6 service only)
B) Disable one of the protocol services and provide access via only one protocol.
C) IPv4/IPv6 dual-stack technology (the outgoing equipment supports both protocols simultaneously, providing services separately).
D) NAT64 (only supports IPv6 terminals accessing IPv4 services)

5. In MPLS VPN network planning, which of the following components are the core elements for building an L3VPN (Layer 3 VPN)? (Multiple choice)

A) PE device (Provider Edge)
B) VLAN segmentation (only used for Layer 2 isolation, unrelated to Layer 3 VPN)
C) CE equipment (Customer Edge)
D) Physical leased line (can build a Layer 3 VPN without MPLS protocol )
E) P equipment (Provider, backbone provider equipment)
