Q18. How does MPLS BGP VPN handle the problem of address overlapping of different VPN sites?

To use different routing protocols In the backbone network for afferent VPN.

To maintain separate VRF lor different VPN.

To allocate unique RT for each VPN.

To allocate different LSP for each VPN.

To allocate unique RD for each VPN.

Q19. There are two MAC address learning modes in the VPLS: unqualified and qualified. In qualified mode, all VLANs are processed by the same VSI and they share the same broadcast domain or MAC address space.

True

False

Q20. Which of the following statements about CAR are correct?

CAR uses token bucket mechanism to measure traffic and allocate bandwidth.

CAR can be used for incoming interface and outgoing interface.

CAR and queue scheduling cannot be used at the same time because of confliction.

CAR can be used to limit the rate of the specific type of traffic.

Q21. BGP Is an exterior gateway protocol which runs among ASs. It focuses on routes control and selection of optimal routes rather than discovery and calculation of routes.

True

False

Q22. EVPN-VXLAN uses EVPN as the control plane and exchanges BGP EVPN routes between VTEPs to implement automatic V7EP discovery and host Information advertisement. This prevents unnecessary data traffic flooding.

True

False

Q23. Which of the following statements about layer 2 LAN switch are incorrect?

LAN switch will modify the data link layer header of the packet and then forward it.

LAN switch can learn Mac address automatically.

LAN switch operates at data link layer.

LAN switch will modify the network layer header of the packet and then forward it.

Q24. LDP uses Initialization message to negotiate LDP parameters with the peer.

True

False

Q25. When router receives two instances of one LSA at the same time, it will first compare LS age, If same ,Uien compare LS Sequence number.

True

False

Q26. In BGP4+, both the NUU field and next-hop attribute can be expressed with an IPv6 address and prefix.

True

False

Q27. Which of the following is not a feature of Segment Routing?

Uses the source routing technology to provide fast interaction between the network and upper-layer applications.

Segment Routing is a connection-oriented technology that maintains the connection status.

By extending existing protocols (such as IGP), the existing network can be smoothly evolved.

In addition, the centralized control mode of the controller and the distribution control mode of the forwarder are supported, and the balance between centralized control and distributed control is provided.

Q28. Which of the following statements about the priority of zone in the Eudemon are correct?

The priority of the Trust zone is 80

The priority of the Untrust zone is 15

The priority of the DMZ is 50

The priority of the Local zone is 100

Q29. The VRRP advertfse-lnterval is 2s, preempt mode is enabled, Delay Time is 3s, then which of the following is the Master_Down_Interval time?

Q30. Compared with VPLS, what are the characteristics of EVPN?

EVPN needs to be configured to be in full connection state on all PEs on the carrier’s backbone network.
That is, PWs must be set up between any two PEs.

By using the EVPN technology, PB on the carrier’s backbone network do not need to establish full connections, which greatly reduces the network complexity and reduces the number of signaling messages.

EVPN enables a device to implement load balancing among multiple EVPN routes with the same destination MAC address but different next hops when managing MAC addresses.

The PE learns the local and remote MAC addresses and their IP addresses through ARP and MAC address advertisement routes, and caches the information locally to prevent ARP request packets from being broadcast to other PEs and reduce network resource consumption.

Q31. The IGMP snooping configuration is as follows:
#
vlan batch 3
#
igmp-snooping enable
#
vlan 3
igmp-snooping enable
#
interface GigabitEthernet1/0/1
port hybrid tagged vlan 3
I2-multicast static-group group-address 225.1.1.1 to 225.1.1.3 vlan 3
#
interface GigabitEthernet3/0/1
port hybrid tagged vlan 3
igmp-snooplng static-router-port vlan 3
Which of the following statements are correct?

The device connected to GE 1/0/1 can receive multicast traffic only for the multicast groups 225.1.1.1 to 225.1.1.3. because static multicast groups are configured on GE 1/0/1.

The device connected to GE 1/0/1 can send Report messages to receive multicast data ‘or multicast groups outside the 225.1.1.1 to 225.1-1.3 range.

IGMP snooping has been enabled on the switch.

The device connected to GE 3/0/1 Is a multicast router.

Q32. The Session ID of PPPoE could be changed during the whole Session Stage.

True

False

Q33. Compared with VPLS, what are the characteristics of EVPN?

EVPN needs to be configured to be in full connection state on all PEs on the carrier’s backbone network. That is, PWs must be set up between any two PEs.

EVPN enables a device to implement load balancing among multiple EVPN routes with the same destination MAC address but different next hops when managing MAC addresses.

Q34. Which of the following statements regarding IP address 224.0.0.1 are correct?

It represents all the hosts and routers.

It represents all the routers.

It is a private IP address.

It is a multicast IP address.

Q35. Which of the following statements regarding the description of MPLS are correct?

Egress LER forwards packets based on IP routing table.

Core LSR forwards packets based on label.

Ingress LER forwards packets based on label.

Core LSR forwards packets based on IP routing table.

Q36. When configuring Diff-Serv in QoS, the edge router on Diff-Serv network classify packets according to its source address, destination address or other parameters, assigning different IP precedence for different packets, while other routers classify packets according to IP precedence.

True

False

Q37. Assuming that a router which only supports IP Precedence receives a packet marked with DSCP, which of the following statements is correct?

The last three bits of DSCP are set to 101.

Eight levels of AF in DSCP are mapped into eight levels of IP Precedence.

The first three bits of DSCP are mapped into three bits of IP Precedence.

All 8 bits of TOS are set to zero.

Q38. Which of the following statements disobey the basic principle of area division?

If the ISP runs OSPF protocol in the whole province network, then one city can be taken as one area.

In the network, there are some sub networks such as 110.1.1.0/24,110.1.2.0/24,110.1.3.0/24, 120.1.1.0/24,120.1.2.0/24 ,120.1.3.0/24.Then all the routers belonging to 110 network can be configured in one area.

One network maybe includes high-end, mid-end and low-end routers. Generally, all of these routers will be in same area.

Make all routers with larger routing-table into one area.

Q39. The VRRP advertfse-lnterval is 2s, preempt mode is enabled, Delay Time is 3s, then which of the following is the Master_Down_Interval time?

Q40. If Adjacency Segment + Node Segment is used together, the entire path can be forced to include an adjacency and load balancing. This mode is called loose path.

True

False
