Huawei HCIP-Datacom-Campus Network Planning and Deployment V1.5 認定 H12-841_V1.5 試験問題:

1. In Huawei's WAN solution, which of the following technologies can "achieve load balancing of traffic in WAN links, while ensuring that traffic automatically switches to other links when one link fails"?

A) Dynamic routing protocols (such as OSPF) + equal-cost routing
B) Manually switch links
C) Static routing with single-link forwarding
D) Relying solely on link aggregation, without configuring a routing protocol.

2. In Huawei's SD-WAN solution, which of the following service optimization strategies can "assign the highest priority to VoIP services to ensure smooth calls"?

A) QoS priority scheduling based on application type (VoIP is the highest)
B) Traffic distribution based on link bandwidth
C) Limit VoIP service bandwidth to avoid consuming excessive resources.
D) All services are forwarded with the same priority.

3. In the wide area network IPv6 transition scenario, which of the following technologies can achieve
"smooth interoperability between IPv4 and IPv6 services" and ensure service continuity? (Multiple choice)

A) Dual-stack technology (the device runs both IPv4 and IPv6 protocol stacks simultaneously)
B) IPv6 over IPv4 tunnels (such as GRE tunnels, which encapsulate IPv6 packets for transmission over IPv4 networks)
C) Directly disable the IPv4 protocol and force all services to switch to IPv6.
D) Without transition technology, IPv4 and IPv6 terminals cannot communicate with each other .
E) NAT64 (enabling IPv6 terminals to access IPv4 resources)

4. In Huawei's WAN solution, which of the following technologies can optimize the transmission experience of "cross-regional video conferencing" and reduce lag and latency? (Multiple choice)

A) Fixed video bitrate, not adjusted according to link status .
B) Video traffic priority scheduling (based on DSCP tag priority forwarding of video data packets)
C) Edge node caching (caching video streams locally to reduce long-distance transmission latency)
D) Dynamic bandwidth adjustment (adjusting video bitrate based on link load)
E) No traffic priority; video and regular data compete for bandwidth.

5. In Huawei's WAN bandwidth management solution, which of the following functions can "limit bandwidth for non-critical services such as P2P downloads and online video to ensure the performance of core services such as ERP and VoIP"?

A) Prioritize bandwidth allocation for non-critical services; allocate bandwidth for core services as needed.
B) Application-type-based bandwidth limiting policy (limiting bandwidth for non-critical services)
C) All services are allocated the same bandwidth without any restrictions.
