For the "cloud access optimization" scenario, which of the following technologies in Huawei's SD- WAN solution can enable "fast access to public cloud (such as AWS, Huawei Cloud) resources by branches"? (Multiple choice)

• A.Cloud dedicated line connection (such as SD-WAN and direct connection to public cloud, reducing transit latency)
• B.All cloud access is relayed through headquarters, increasing transmission latency.
• C.Cloud routing optimization (automatically learns public cloud network segments, avoiding manual configuration of static routes)
• D.Manually configuring a large number of static routes is complex to maintain .
• E.Edge nodes connect to the nearest cloud node (select the cloud access point closest to the branch).

In Huawei's WAN bandwidth optimization solution, for "cross-regional transmission of office collaboration tool traffic (such as Lark, DingTalk)," which of the following technologies can
"optimize collaborative data transmission and reduce file transfer latency"?
