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

1. In a wide area network (WAN) IPv6 transition scenario, if "an enterprise needs to publish IPv6 services to the outside world, and the outside world only supports IPv4 access", which of the following technologies should be adopted?

A) NAT46 (translates external IPv4 addresses into internal IPv6 addresses to enable access)
B) IPv4/IPv6 dual-stack technology (requires external IPv6 support)
C) DNS64+NAT64 (only enables internal IPv6 to access external IPv4)
D) IPv6 over IPv4 tunnel (only allows access from IPv6 terminals)

2. In Huawei's SD-WAN solution, which of the following technologies can "automatically re-establish a VPN tunnel with headquarters after a branch device changes its public IP address, without manual intervention"?

A) SD-WAN Dynamic IP Adaptation Technology (Automatically detects changes in public IP address and re-initiates tunnel connection)
B) Manually reconfigure VPN tunnel parameters and update the public IP address.
C) Fixed public IP address for branch offices; dynamic changes are not supported.
D) Disable the VPN tunnel automatic reconnection function; manual triggering is required.

3. In an MPLS VPN network, which of the following failures will cause "MPLS LSPs between PE devices to fail to be established, and VPN data to fail to be forwarded"?

A) OSPF neighbor between PE and CE is established normally.
B) BGP VPNv4 neighbors are established normally between PE devices.
C) The routing protocol on the CE device is configured correctly.
D) MPLS LSR-ID is not configured on the PE device.

4. In Huawei's WAN solution, for the scenario of "frequent brief interruptions in WAN links", which of the following technologies can "reduce the impact of interruptions on services and achieve rapid service recovery"?

A) Ignore the link interruption and do nothing.
B) Switchover is triggered based on the default timeout of the routing protocol (e.g., OSPF dead timeout of 40 seconds).
C) Fast rerouting technology based on BFD (millisecond-level switch to backup path in case of interruption)
D) All services use a single link, with no backup path.

5. In Huawei's WAN bandwidth optimization solution, for "incremental data backup of databases transmitted across regions," which of the following technologies can "transmit only newly added or changed data blocks, reducing the amount of data transmitted"?

A) Transfer complete database backup files, without distinguishing between incremental and full backups.
B) Compress the complete backup file before transferring it; this will not reduce the number of data blocks.
C) Reduce the frequency of incremental data transmission and transmit it all at once after accumulation.
D) Database incremental backup data block-level transfer technology (transfers only changed data blocks)
