In an M-LAG, two CE series switches send M-LAG synchronization packets through the peer-link to synchronize information with each other in real time. Which of the following entries need to be included in the M-LAG synchronization packets to ensure that traffic forwarding is not affected if either device fails? (Select All that Apply)

• MAC address entries
• Routing entries
• IGMP entries
• ARP entries

Which of the following statements are true about IP address planning for a DC? (Select All that Apply)

• Service addresses refer to the IP addresses of servers, hosts, and gateways.
• IP addresses with a 24-bit mask are recommended for use as interconnection IP addresses.
• IP addresses must be contiguous. The routes with contiguous IP addresses can be summarized easily on a hierarchical network.
• IP address allocation should be simple and easy to manage, reflect network layers, and simplify network management and network expansion.

In the computing scenario of Huawei CloudFabric Solution, which of the following services are optional for controller interconnection? (Select All that Apply)

• Interconnection with FabricInsight
• Interconnection with the authentication server
• Interconnection with eSight
• Interconnection with the VMM

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?

• No return route is configured on the PE.
• The engineer did not check whether the service loopback interface needs to be configured on the VXLAN network based on the switch model.
• No firewall security policy is configured when host traffic passes through the firewall.
• The MAC address of the NVE interface on the VXLAN network is not manually specified.

How many rollback levels does Huawei's iMaster NCE-Fabric support?

• 3
• 4
• 2
• 1

Which of the following statements are true about a routing design that employs OSPF on the underlay network of a DC? (Select All that Apply)

• Typically, the IP address of Loopback0 is configured as the VTEP IP address and the same IP address is planned for active-active leaf nodes in the same group.
• The network type of spine and leaf nodes can be set to P2P in order to accelerate convergence.
• This routing design is recommended when the DC has more than 300 switches.
• It is recommended that all devices be planned in Area 0.

• STP prevents loops caused by incorrect configurations or connections in an M-LAG.
• TRUE
• FALSE

Linux consists of the user space and kernel space. Which of the following functions are included in the kernel space? (Select All that Apply)

• The NIC driver sends data frames.
• Data encapsulation
• Bit stream transmission
• Data encryption

Which of the following statements is false about centralized gateway deployment using BGP EVPN?

• When configuring a VTEP, you need to create a Layer 2 BD and bind a VNI to the Layer 2 BD.
• A VXLAN tunnel is identified by a pair of VTEP IP addresses and can be established if the local and remote VTEP IP addresses are reachable to each other at Layer 3.
• When BGP EVPN is used to dynamically establish a VXLAN tunnel, the local and remote VTEPs first establish a BGP EVPN peer relationship and then exchange BGP EVPN routes to transmit VNI and VTEP IP address information. A VXLAN tunnel is then dynamically established between them.
• When configuring a VTEP, you need to create an EVPN Instance in the Layer 2 BD and configure an RD for the local EVPN instance. You do not need to configure an RT.

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