Huawei HCIE-Datacom V1.0 認定 H12-891_V1.0 試験問題 (Q315-Q320):

質問 # 315
In the topology shown in the figure. Running the OSPFv3 protocol over the entire network does not produce what type of LSA on R1 without external route introduction?

正解:D


質問 # 316
Regarding BGP route filtering, the following description is wrong?

正解:D


質問 # 317
If a DR needs to be elected between multicast routers running PIM-SM to be responsible for the sending and receiving of source or member multicast data, which one is described correctly below for the DR election rule?

正解:D


質問 # 318
In a VXLAN scenario, which of the following features can be enabled to reduce ARP packet flooding between VTEPs?

正解:A、C、D

解説:
VXLAN networks suffer from ARP flooding because ARP requests are broadcasted across all VTEPs in a Layer 2 domain. To reduce ARP flooding, the following mechanisms can be enabled:
✅ A. Local Proxy ARP
Allows the local VTEP to respond to ARP requests without forwarding them across the VXLAN network.
The VTEP caches MAC-IP mappings and replies directly to ARP requests, reducing unnecessary flooding.
✅ B. ARP Broadcast Suppression
Converts ARP broadcast packets into unicast or multicast packets to minimize network-wide flooding.
✅ C. Host Information Collection
Collects and stores MAC-IP bindings of endpoints, which can be used by proxy ARP to reduce flooding.
❌ D. Port Isolation
Port isolation prevents communication between devices within the same VLAN but does not help reduce ARP flooding between VTEPs.
