QUESTION NO: 1
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. DNS64+NAT64 (only enables IPv6 terminals to access IPv4 resources) C. NAT444 (only performs IPv4 address translation) D. IPv6 over IPv4 tunnel (only enables communication between IPv6 terminals)

Correct Answer: A

QUESTION NO: 2
In the wide area network IPv6 transition scenario, which of the following technologies can achieve
"smooth interoperability between IPv4 and IPv6 services" and ensure service continuity? (Multiple choice)

A. Directly disable the IPv4 protocol and force all services to switch to IPv6. B. NAT64 (enabling IPv6 terminals to access IPv4 resources) C. Dual-stack technology (the device runs both IPv4 and IPv6 protocol stacks simultaneously) D. IPv6 over IPv4 tunnels (such as GRE tunnels, which encapsulate IPv6 packets for transmission over IPv4 networks) E. Without transition technology, IPv4 and IPv6 terminals cannot communicate with each other .

Correct Answer: B,C,D

QUESTION NO: 3
In Huawei's WAN management platform, which of the following functions can "set threshold alarms for device CPU and memory usage (e.g., alarm when CPU > 80% and memory > 90%) to promptly detect device overload"?

A. Configure compliance checks B. Device hardware resource threshold alarm C. Link quality monitoring and alerts D. Network topology visualization

Correct Answer: B

QUESTION NO: 4
In the OSPF protocol for wide area networks, which of the following is the core information contained in Type 2 LSA (Network LSA)?

A. Prefixes and metrics for external routes within the NSSA area B. Prefix and metric of inter-area summary route C. Prefix and next hop of external routes to the AS D. The DR router ID that generated this LSA and the IDs of all routers in the network.

Correct Answer: D

QUESTION NO: 5
In Huawei's SD-WAN solution, which of the following technologies can "achieve full interconnection communication between multiple branches without manually creating tunnels between each pair of branches"?

A. Direct communication between branches is prohibited; access to headquarters is permitted only. B. Manually creating point-to-point tunnels for each pair of branches is complex to configure. C. SD-WAN Fully Interconnected Automatic Tunneling Technology (Dynamically Discover Branches and Establish Tunnels) D. All inter-branch communication is relayed through headquarters, increasing latency.

Correct Answer: C

QUESTION NO: 6
In a WAN BGP protocol deployment, if it is necessary to "filter out routes with a mask length greater than 24 bits when receiving routes advertised by neighbors", which of the following policies should be configured?

A. Configure BGP neighbor MD5 authentication B. Enable BGP route aggregation to merge routes with a mask length greater than 24 bits. C. Adjust the BGP Local Preference property to reduce the priority of long-mask routes. D. Apply a prefix-list to the BGP neighbor inbound direction to limit the mask length to 24.

Correct Answer: D

QUESTION NO: 7
In a WAN BGP routing policy, which of the following BGP attributes can "control the route selection order within the local AS, with the highest priority route being selected first"?

A. MED B. AS_PATH C. Next Hop D. Local Preference

Correct Answer: D

QUESTION NO: 8
In the OSPF protocol for wide area networks, which type of LSA will the ABR of a "Stub area " publish to the area to guide routers within the area to access external networks?

A. Type 7 LSA (NSSA External Router) B. Type 3 LSA Inter-area summary route C. Type 3 LSA default route (0.0.0.0/0) D. Type 5 LSA (AS External Route)

Correct Answer: C

QUESTION NO: 9
In an MPLS VPN network, which of the following descriptions conforms to the allocation logic of
"VPN label (inner label)"?

A. Assigned by the PE device based on the VPN instance, used to identify the VPN to which the data packet belongs. B. Fixed to a default value, not changing with VPN instance. C. Assigned by the P device according to the backbone network topology, used to identify the forwarding path. D. Assigned by the CE device based on local routing, used to identify the service type.
