Question No : 10

In a WAN BGP protocol deployment, if it is necessary to "modify the Local Preference property of a route when receiving routes advertised by neighbors, so that a specific route is selected preferentially", which of the following strategies should be configured?

A.Apply route-policy to the BGP neighbor inbound direction and set the Local Preference value.
B.Configure BGP neighbor MD5 authentication
C.Enable BGP route aggregation, merge routes, and then modify their properties.
D.Apply a prefix-list to filter routes in the outbound direction of BGP neighbors.

정답:

Question No : 11

In Huawei's WAN bandwidth optimization solution, for " office documents (such as Word and Excel) transmitted across regions", which of the following technologies can "reduce the transmission of duplicate files and improve efficiency"?

A.Sort by file size and transfer smaller files first.
B.Duplicate file filtering based on file fingerprints (files that have already been transmitted will not be transmitted again).
C.Transfer all files directly without performing duplicate checks.
D.Compress the file before transmission without changing the number of transmissions.

정답:

Question No : 12

In an MPLS VPN network, after a PE device learns a route from a CE device, which of the following operations can "convert the route into a VPNv4 route and advertise it to other PE devices"?

A.Configure routing policies on the PE device to import CE routes into the BGP VPNv4 address family.
B.Enable the MPLS protocol on the CE device and directly advertise VPNv4 routes.
C.Configure BGP VPNv4 neighbor on the P device to pass routes.

Question No : 13

In Huawei's SD-WAN solution, for the scenario of " simultaneous access of branch dual links (Internet + 5G)", which of the following technologies can "achieve traffic load sharing between the two links, and ensure uninterrupted service when a single link fails"?

A.Use only one link, with the other link as a cold backup (manually switch over in case of failure).
