Huawei HCIE-Data Center Network (Written) V1.0 Sample Questions:

1. 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 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
C) 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

2. With respect to CloudFabric's ZTP scenario, which of the following types of servers does the device get the configuration file from?

A) Syslog server
B) DHCP server
C) Version File Server
D) Intermediate file servers

3. In the Multi-PoD solution of the CloudFabric solution, when the VPC communicates through the wall, which of the following methods does the FW and Service Leaf use to open up the route?

A) Static routes
B) OSPF
C) BGP
D) Policy-based routing

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) 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
C) A heartbeat cable is deployed between the two FWs to check the status of the peer FW and the heartbeat link connectivity
D) 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
