In Huawei's SD-WAN solution, which of the following technologies can "achieve dynamic synchronization of routes between branches and the public cloud without manually updating cloud network segment routes"?

• A.Using only the default route pointing to the cloud cannot accurately match the cloud network segment.
• B.Disable routing interaction between the branch and the cloud, and only access cloud resources via the internet.
• C.Cloud routing dynamic synchronization technology (such as automatic synchronization with Huawei Cloud VPC routes)
• D.Manually configure static routes to point to the cloud network segment, and reconfigure them when the cloud network segment changes.

In Huawei's WAN solution, for scenarios with " large fluctuations in WAN link bandwidth," which of the following technologies can "dynamically adjust the transmission rate to adapt to bandwidth changes"?

• A.Adaptive rate adjustment technology (adjusts the rate in real time based on link bandwidth)
• B.Fixed transmission rate, not adjusted with bandwidth.
• C.Reduce the transmission rate to the minimum to ensure uninterrupted transmission.
• D.Transmit data only when bandwidth is sufficient; suspend transmission when bandwidth is insufficient.

In the wide area network IPv6 transition scenario, if "internal IPv4 and IPv6 terminals need to communicate with each other", which of the following technologies should be adopted?

• A.IPv4/IPv6 dual-stack technology (terminals support both protocols simultaneously, enabling direct interoperability).
• B.NAT444 (only performs IPv4 address translation)
• C.DNS64+NAT64 (only enables IPv6 terminals to access IPv4 resources)
• D.IPv6 over IPv4 tunnel (only enables communication between IPv6 terminals)

In the OSPF protocol for wide area networks, what is the main difference between a "full stub area" and a "normal stub area"?

• A.Fully stub areas do not receive Type 3 LSAs (Inter-area summary routes), while regular stub areas do.
• B.Fully stub areas receive Type 5 LSAs (AS external routes), while ordinary stub areas do not.
• C.A fully stub region is no different from a regular stub region, only the configuration is different.
• D.Fully stub regions receive only Type 1/2 LSAs, while ordinary stub regions receive Type 1/2/3 LSAs.

In a WAN BGP protocol deployment, if it is necessary to "modify the AS_PATH attribute of the route and add the local AS number when advertising routes to EBGP neighbors", which of the following strategies should be configured?

• A.Enable BGP route aggregation and merge AS_PATH
• B.Apply a prefix-list to filter routes on the inbound direction of BGP neighbors.
• C.Configure BGP neighbor MD5 authentication
• D.Apply as-path-filter to the outbound direction of BGP neighbors and add the local AS number.
