Huawei HCIE-Data Center Network (Written) V1.0 Sample Questions:
1. Which of the following components does calico consist?
A) BGP client
B) Route Reflector
C) Felix
D) etcd
2. In the Multi-Site scenario of a CloudFabric solution, what are the correct items in the following description of Layer 2 interoperability?
A) In practice, different sites have their own independent VNI space, so VXLAN tunnels inside different sites are likely to use different VNI C. Layer 2 interconnection is supported in two modes: local VNI and mapped VNI
B) In local VNI mode, the local VNI of the local Fabric GW is used as the outbound VXLAN packet to encapsulate VXLAN packets to the VNI
C) In the mapped VNI mode, the Fabric GW at both ends uses BGP EVPN to negotiate a mapped VNI, and all packets sent to the peer end are routed using the mapped VNI VXLAN packing
3. In the Huawei CloudFabric data central network, if the VPC subnet is communicated through the iMasterNCEFabric agency, which of the following configurations will be delivered by the controller to the physical device?
A) Create a gateway VBDIF port and associate the VRF
B) Create a Layer 2 sub-interface and associate it with the corresponding BD
C) Create a VRF for the VPC
D) Create a BD and associate L2VNI
4. In a CloudFabric solution, the fault detection and fault-tolerant design of the firewall includes ?().
A) Link fault: If any link on the edge leaf of the FW primary connection fails, the M-lag member port goes down, and the double homing becomes single homing, which does not affect the forwarding of FW primary traffic
B) It is recommended that each FW and service be connected in a single-arm mode, and the upstream and downstream logical ports fail at the same time, resulting in higher failover performance
C) A heartbeat cable is deployed between the two FWs to check the status of the peer FW and the heartbeat link connectivity
D) FW fault: After the FW is switched over to the primary/standby, the FW sends a free ARP packet to trigger the refresh of the forwarding entries on the switch and direct the traffic to the FW standby
5. IN THE CLOUDFABRIC SOLUTION, WHEN USING MDC TO ROW AWS HAS A CLOUD NETWORK, IGWS IN THE AWS TYPE WILL BE PROJECTED AS WHICH OF THE FOLLOWING OPTIONS? ?
A) External Gateways
B) IGW routing table
C) TransitRouter
D) Logic Router
