7. In EVPN, Type 5 routes are used only by hosts on a VXLAN network to access external networks.

8. In the VPC interworking scenario, traffic is checked and filtered only by the firewall in the source or destination VPC.

9. Both M-LAG and stacking technologies can overcome the disadvantages of traditional DCNs.

However, M-LAG is a better choice to ensure 24/7 service continuity.

10. An enterprise builds a DC and deploys iMaster NCE-Fabric to automatically deliver network configurations. After the engineer manually deploys the underlay network and delivers overlay network configurations through iMaster NCE-Fabric, it is found that tenant hosts cannot access external networks.

Which of the following is not a possible cause of this fault?

A. No return route is configured on the PE.

B. The engineer did not check whether the service loopback interface needs to be configured on the VXLAN network based on the switch model.

C. No firewall security policy is configured when host traffic passes through the firewall.

D. The MAC address of the NVE interface on the VXLAN network is not manually specified.

A. Device

B. Protocol

C. Service

D. Application

E. Configuration

12. A vNIC can transmit data only in bit stream mode.

13. 1.Which of the following is not an advantage of link aggregation on CE series switches?

14. A hypervisor virtualizes the following physical resources: memory, and input/output (I/O) resources. (Enter the acronym in uppercase letters.)

15. In the CloudFabric Solution, SecoManager and iMaster NCE-Fabric are deployed independently. After SecoManager is installed, it needs to be manually interconnected with iMaster NCE-Fabric.

B. Service provisioning

C. O&M and monitoring

D. Change optimization

17. A VXLAN tunnel is identified by a pair of VTEP IP addresses. During VXLAN tunnel establishment, the local and remote VTEPs attempt to obtain each other's IP addresses. If the VTEP IP addresses are reachable to each other at Layer 3, a VXLAN tunnel can be established.

18. M-LAG configuration consistency check classifies device configurations into key configurations (Type

1) and common configurations (Type 2). This check can be performed in strict or loose mode based on the processing mode when key configurations are inconsistent.

Which of the following statements is false about M-LAG configuration consistency check?
