7. When configuring MPLS VPNI, the administrator configured the command: interface GigabitEthernet0/0/0 ip binding vpn-instance VPN1 Interface GigabitEthernet0/0/1 ip binding vpn-instance VPN2. Which of the following description is wrong?

This configuration command is usually configured on the PE device

The function of this command is to bind the G0/0/1 and G0/0\/2 interfaces on the PE device to the VPN instance assigned to the customer network

After an interface on the device is bound to a VPN instance, the interface becomes a private network interface, and a private network address can be configured and a private network routing protocol can be run.

If you unbind the device from the interface and the VPN instance, it will not automatically clear the IPv4 or IPv6 configuration under the interface bound to the VPN instance.

RADIUS automatic detection of users

Accounting server address and port

Shared-key

Question 13 of 25

14. Different virtual machines can use the VTEP tunnel established by vswitchi to communicate with VXLAN. Then the communication process of VXLAN is: 1 The source VTEP encapsulates the ARP broadcast sent by the source VM into a multicast packet and sends it to the L3 network. 2 After receiving the multicast packet, the destination VTEP learns the mapping relationship between the source VM and VTEP, and forwards the multicast packet to the local VM. 3 Local unicast response. 4 The destination VTEP encapsulates the Vxlan tunnel, establishes a mapping table and encapsulates it, and then unicasts it to the source VTEP. 5 The source VTEP receives the response and establishes the mapping relationship between the target VM and the target VEP, removes the tunnel and forwards it to the source VM. 6 The source VM and the target VM communicate unicast packets through the tunnel.

Question 14 of 25

15. ASPF (Application Specific Packet Filter) is a packet filter based on the application layer. It checks the application layer protocol information and monitors the linked application layer protocol status, and implements a special security mechanism through the Server Map table. Which of the following statement about ASPF and Server map table is wrong?

ASPF monitors messages during communication

ASPF dynamically creates and deletes filtering rules

ASPF dynamically allows multi-channel protocol data to pass through the Servermap table

The five-tuple Server-map entry implements a similar function to the session table

Question 15 of 25

16. In the MPLS network, the switch will assign the description of the label assignment method, which of the following is correct?

It can be up to the downstream SR to decide to assign a label to a specific FEC

Downstream on demand DoD (downstream on demand) refers to a specific FEC

The downstream self-allocated label method refers to a specific FEC

The label distribution methods used by upstream LSR and downstream LSR with label distribution adjacencies can be consistent

Question 16 of 25

17. The main technical schools of SDN advocate that SDN adopts a layered open architecture. Which technical advocates and defines centralized architecture and Openflow?

ETSI

ONF

ITU

Question 17 of 25

18. The dynamic IP address assigned to the client by the DHCP server. Usually there is a certain rental period, which of the following description of the rental period is wrong?

The lease renewal timer is 50% of the total lease period. When the "lease renewal timer" expires, the DHCP client must renew the IP address

The rebinding timer is 87.5% of the total lease period

If the "rebinding timer" expires, but the client has not received a response from the server, it will always send a DHCP REQUEST message to the DHCP server that has previously assigned an IP address until the total lease expires.

If the client receives a DHCP NAK message within the lease period, the client will immediately stop using this IP address and return to the initialization state, and re-apply for a new IP address

Question 18 of 25

19. Regarding the description of OSPF's neighbor relationship failure, which of the following statements is false?

Stalling in ExStart state may be due to MTU mismatch between neighboring routers

Stalling in the lnit state indicates that the router has received the neighbor's Hello packet, but the Hello packet does not contain the OSPF Router ID of the router

The two router databases are synchronized, and an error occurs in the SPF calculation. It must be because the router ID is duplicated

For a pair of DR Others on an Ethernet link
