Questions # 66:

In an iNOF network, which of the following information can be transmitted in an iNOF message?

Options:

Interface Error-Down information

Domain configuration information

Host dynamics

Layer 2 VNI information

Expert Solution

Answer

A, B, C

Explanation

Parsing: iNOF packets are TCP-encapsulated packets with TCP port numbers ranging from 10000 to 57999 and 19516 by default , which contains key iNOF information in the Data field of TCP packets. The client can send key iNOF information to the reflector through the iNOF packet, and the reflector summarizes it and then sends it to other clients. Through iNOF messages

The following types of information can be transmitted: Connection information: ▫ The iNOF reflector and the client need to exchange iNOF packets to establish an iNOF connection, similar to TCP connection. ▫ Domain configuration information: In the iNOF system, the device can manage the connected host through the zone, and after the iNOF domain configuration is completed on the iNOF reflector, it will pass through the iNOF The packet sends the domain configuration information to each client. ▫ Host dynamic information: When a new host connects to the client or leaves the client, the host will actively send LLDP packets to the client, and the LLDP will be recorded in the packet The change of neighbor information allows other devices in the iNOF system to perceive the host dynamic information. ▫ Interface Error-Down Information: Interface Error-Down is triggered when the iNOF device is triggered due to a PFC deadlock or a CRC error packet that reaches the alarm threshold After that, the iNOF packet will carry the interface Error-Down information, so that other devices in the iNOF system can quickly sense it and adjust the path information in time. •After the iNOF system is established, all devices in the system can perceive the changes of the access host at the first time, so that the information can be fed back to each intelligent lossless network function, and the relevant configuration can be intelligently adjusted, so that the network can finally achieve low latency, no packet loss, and high throughput performance.

Questions # 67:

In the CloudFabric solution, which of the following is the correct order in which VMs are launched in the computing linkage scenario: (1) Created by the computing administrator

Question # 67

VM;(2) iMaster NCE-Fabric obtains VM on-line information through VMM (3) The network administrator creates the corresponding virtual network through iMaster NCE-Fabric (4) iMaster NCE-Fabric senses the location of the VM and automatically delivers the mapping of VLAN and VNI

Options:

1234

3142

4132

3124

Questions # 68:

In Huawei's CloudFabric solution, in the scenario where the Border Leaf and Service Leaf are separated, what are the correct descriptions of the following principles for traffic orchestration between internal and external networks?

Options:

The controller creates the corresponding tenant VRF and egress VRF on the Border Leaf based on the tenant network and the external network

The route to the external network on the border leaf is delivered by the iMaster NCE-Fabric controller, and only static routes can be delivered to connect with the external network

The controller creates the corresponding tenant VRF and egress VRF on the Service Leaf based on the tenant network and the external network

The backhaul route from the external network to the tenant network needs to be configured by the external network and cannot be delivered by the iMaster NCE-Fabric controller

Expert Solution

Questions # 69:

In a VXLAN network, VTEP1 sends an IRB route with an RT value of 100:1 to VTEP2 VTEP2 will drop the route?

Options:

In VTEP2, the inbound RT of EVPN instances is 100:1, and the inbound RT of IP VPN instances is 200:1

In VTEP2, the inbound RT of EVPN instances is 200:1, and the inbound RT of IP VPN instances is 100:1

In VTEP2, the inbound RT of EVPN instances is 100:1, and the inbound RT of IP VPN instances is 100:1

In VTEP2, the inbound RT of EVPN instances is 200:1, and the inbound RT of IP VPN instances is 200:1
