NO.54 In a WAN BGP protocol deployment, if it is necessary to “modify the Next Hop attribute of the route to the directly connected address of that neighbor when advertising a route to a specific EBGP neighbor”, which of the following strategies should be configured?

Apply the next-hop-local strategy in the outbound direction of BGP neighbors.

Configure BGP neighbor MD5 authentication

Adjust the Local Preference property of the BGP route.

Enable BGP route aggregation, merge routes, and then publish them.

NO.55 In Huawei’s SD-WAN solution, for the scenario of “VPN communication between multiple branches”, which of the following technologies can “achieve direct communication between branches without the need for headquarters relay”?

All inter-branch communication is relayed through headquarters, increasing latency.

SD-WAN inter-branch full interconnection tunnel technology (dynamically establishing direct connection tunnels between branches)

Only branch offices are allowed to access headquarters; direct communication between branches is prohibited.

Manually creating point-to-point tunnels for each pair of branches is complex to configure.

NO.56 In a wide area network (WAN) BGP protocol deployment, if it is necessary to “set the MED attribute of the route to a specific value when advertising routes to EBGP neighbors, thus affecting the neighbor’s route selection “, which of the following strategies should be configured?

Apply route-policy in the outbound direction of BGP neighbors and set the MED value.

Configure BGP neighbor MD5 authentication

Enable BGP route aggregation, merge routes, and then modify the MED.

Apply a prefix-list to filter routes on the inbound direction of BGP neighbors.

NO.57 In a WAN BGP protocol deployment, if it is necessary to “control the range of routes advertised by the local AS to its neighbors, and only advertise routes to specific network segments”, which of the following policies should be configured?

BGP Neighbor MD5 Authentication

BGP route aggregation

BGP route filtering (e.g., prefix-list)

Adjust BGP Local Preference properties

NO.58 In the WAN BGP protocol, if “route reflectors are configured between IBGP neighbors, but no clients are configured for the reflectors”, which of the following problems will this cause?

The route reflector cannot pass reflected routes to non-client neighbors.

IBGP neighbor relationships cannot be established.

The route reflector cannot receive routes from the client’s neighbors.

The route reflector automatically treats all neighbors as clients, reflecting routes normally.

NO.59 In an MPLS VPN network, which of the following configurations is a necessary condition for “PE devices and CE devices to exchange routes via OSPF”?

Enable the OSPF protocol under the VPN instance on the PE device and establish a neighbor relationship with the CE device.

Configure the OSPF protocol on the P device to transmit routes between the PE and CE.

Enable the MPLS protocol on the CE device and support OSPF label forwarding.

Disable the BGP VPNv4 address family on the PE device and use only OSPF.

NO.60 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?

Apply as-path-filter to the outbound direction of BGP neighbors and add the local AS number.

Configure BGP neighbor MD5 authentication

Enable BGP route aggregation and merge AS_PATH

Apply a prefix-list to filter routes on the inbound direction of BGP neighbors.

NO.61 In an MPLS VPN network, if “a VPN instance’s routing table on the PE device lacks routes advertised by the CE device,” which of the following troubleshooting steps should be performed first?

Check the BGP VPNv4 neighbor status between the PE and other PE devices.

Check if the routing protocol between the PE and CE devices is normal (e.g., OSPF neighbor status).

Check if the MPLS LSP is established on the P device.

Check if the CE equipment has any hardware malfunctions.

NO.62 (Refer to the following route queried using a command on the VTEP. Which of the following statements about the route are true?)
[VTEP] display bgp evpn all routing-table mac-route 0:48:b0d5-9dc7-3c41:32:172.16.1.173 BGP local router ID : 1.1.1.1 Local AS number : 100 Total routes of Route Distinguisher(1:3): 1 BGP routing table entry information of 0:48:b0d5-9dc7-3c41:32:172.16.1.173:

This is an IRB Type 2 route.

This is an ARP Type 2 route.

The VPN instance whose IRT is 0:2 or 0:3 can learn the host route information contained in the route.

This route contains the RT and EVPN Router’s MAC Extended Community attribute.

NO.63 In Huawei’s WAN solution, for “collaborative office files (such as shared documents) transmitted across regions,” which of the following technologies can “reduce file synchronization latency and improve collaboration efficiency”?

Reduce the frequency and number of file synchronizations.

Only increase link bandwidth without optimizing the synchronization mechanism.
