In Huawei's WAN solution, for the scenario of " high WAN link latency leading to slow database query response", which of the following technologies can "optimize database query performance and reduce response latency"?

• A.Increase the CPU configuration of the database server without optimizing the transmission process.
• B.Execute the query request directly without optimization.
• C.Database query caching (edge node caching of duplicate query results) + query statement optimization
• D.Reduce the frequency of query requests to decrease server load.

• B.There is no difference between a full NSSA region and an NSSA region, only the name is different.
• C.Fully NSSA areas do not receive Type 3 LSA (Inter-area summary routes), while NSSA areas do.
• D.Full NSSA areas only receive Type 1/2 LSA; NSSA areas receive Type 1/2/3/7 LSA.

In Huawei's WAN solution, for "real-time video surveillance (such as 4K surveillance streams) transmitted across regions," which of the following technologies can "reduce bandwidth usage while ensuring surveillance image quality"?

• A.The surveillance video is transmitted at a fixed bitrate without optimization.
• B.Reduce the frame rate of the surveillance video to 10fps, thus reducing smoothness.
• C.265)
• D.H.265+ encoding technology for surveillance video (saving 30% more bandwidth compared to
• E.Reduce the resolution of the surveillance video to 1080P, sacrificing image quality.
