In Huawei's SD-WAN solution, which of the following technologies can "ensure that the VPN tunnel data encryption algorithm between branches and headquarters is the national standard SM4, meeting the compliance requirements of information security level protection"?

• A.Automatically selects the encryption algorithm; it is not possible to manually specify the national standard encryption algorithm.
• B.It consistently uses international encryption algorithms (such as AES) and does not support Chinese national encryption algorithms.
• C.Unencrypted tunnel data, relying solely on MPLS label hiding.
• D.Specify the encryption algorithm as SM4 in the SD-WAN tunnel configuration.

In Huawei's WAN solution, for the scenario where " WAN link bandwidth fluctuations cause file transfers to be sometimes fast and sometimes slow," which of the following technologies can
"smooth the impact of bandwidth fluctuations and stabilize file transfer rates"?

• A.Transfer files only during peak bandwidth periods, pausing at other times.
• B.Lower the priority of file transfers and prioritize other services.
• C.Token bucket-based traffic smoothing technology (controlling file sending rate to avoid sudden rate fluctuations)
• D.Ignore bandwidth fluctuations and transfer files directly.

In Huawei's WAN bandwidth optimization solution, for "cross-regional web browsing traffic (HTTP/HTTPS)," which of the following technologies can "accelerate webpage loading speed and reduce waiting time"?

• A.Edge caching of static web page resources (such as images and JS files cached to edge nodes).
• B.Directly transmit webpage data without any optimization.
• C.Reduce webpage resolution, sacrificing display quality for speed.
• D.Only increase link bandwidth without optimizing web page transmission mechanisms.

In Huawei's SD-WAN solution, which of the following technologies can "enable branch devices to establish IPsec VPN tunnels with headquarters in a NAT environment without manually configuring NAT mapping"?

• A.All branch devices use the same public IP address, and a tunnel is established through port multiplexing.
• B.Disable the address translation function of the NAT device and communicate directly using the public IP address.
• C.Manually configure port forwarding on the NAT device to expose the public IP address of the branch device.
• D.SD-WAN NAT traversal technology (branch actively initiates tunnel connections to headquarters, traversing NAT)

In Huawei's WAN solution, for scenarios with " excessive WAN link latency (such as intercontinental links)," which of the following technologies can "optimize TCP protocol transmission performance and reduce the impact of latency on services"?

• A.Switching to UDP protocol for transmission does not guarantee reliability.
• B.Use the original TCP configuration directly without optimization.
• C.Reduce TCP transmission rate and decrease data transmission volume.
• D.Enable the TCP window expansion option (increase the TCP receive window).
