H12-841_V1.5 · Question #232
For the "branch multi-link access" scenario, which of the following functions of Huawei's SD-WAN solution can achieve load balancing and redundancy backup of the links? (Multiple choice)
The correct answer is A. Traffic sharing based on bandwidth ratio (e.g., Internet links handle 70% of the traffic, MPLS links B. Link health checks (such as ICMP ping, TCP probes to monitor link status in real time) C. Rapid link failure switching (detecting failures in milliseconds and switching to backup links). See the full explanation below for the reasoning.

For the "branch multi-link access" scenario, which of the following functions of Huawei's SD-WAN solution can achieve load balancing and redundancy backup of the links? (Multiple choice)
Options
- ATraffic sharing based on bandwidth ratio (e.g., Internet links handle 70% of the traffic, MPLS links
- BLink health checks (such as ICMP ping, TCP probes to monitor link status in real time)
- CRapid link failure switching (detecting failures in milliseconds and switching to backup links)
- DAll traffic flows through a single link, with other links left idle as cold backups.
- ENo link health check; manual link switching is required after a failure .
