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. Apply as-path-filter to the outbound direction of BGP neighbors and add the local AS number.
• D. Configure BGP neighbor MD5 authentication

In the deployment of the OSPF protocol in a wide area network, what is the core function of the
"ASBR (Autonomous System Border Router)"?

• A. Connect OSPF Autonomous Systems with other Autonomous Systems and pass external routes from the AS.
• B. Generate a Type 2 LSA to describe router information within the network.
• C. Connect different OSPF areas and pass inter-area routes.
• D. Generate a Type 3 LSA to describe the summarized routes between areas.

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

In Huawei's SD-WAN solution, for the scenario of " multi-tenant sharing SD-WAN network", which of the following technologies can "ensure that the service traffic and configuration of different tenants are completely isolated"?

• A. Create a separate SD-WAN tenant instance (with independent routing and bandwidth) for each tenant.
• B. Tenants share the same configuration template and bandwidth resources.
• C. Filtering tenant traffic only via ACL, without configuring isolation.
• D. All tenants use the same VPN instance, with services differentiated by IP address.

In an MPLS VPN network, when a PE device forwards data packets to a CE device, if the PE device fails to remove the inner VPN label, which of the following problems will occur?

• A. The CE device cannot recognize the tag and discards the data packet.
• B. The PE device automatically re-labels and then forwards the data.
• C. Data packets are forwarded to the CE device normally, without affecting services.
• D. The P device is unable to forward data packets (missing public network label).
