True

False

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.

NO.25 The OF election mechanism avoids network resource waste caused by repeated traffic received by CE1 from two PEs. Which of the following NIRI Is used to implement this feature?

Ethernet Auto-Discovery route

MAC advertisement route

Inclusive Multicast Route

Ethernet Segment Route

NO.26 Which of the following statements about traffic policy In CBQ configuration ate correct?

Traffic policy nesting means one QoS policy contains another QoS policy, the behavior of the parent policy Is a sub-policy.

Traffic policy is used to bind traffic classifier with traffic behavior.

Traffic policy can be nested infinitely.

The traffic policy applied to some interface can not be deleted.

NO.27 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.

NO.28 Which of the following MPLS TE components is used to set up tunnel?

Path calculation

Information distribution

Packet forwarding

Signaling

NO.29 The PPPoE Session Stage is a complete PPP procedure.

True

False

NO.30 Which of the following statements regarding DIS election is correct?

When the priority is the same, the router with higher IP address will be elected as the DIS.

When a DIS fails, the backup DIS will take over.

The IS-IS router with the highest priority in the whole broadcast network will be elected as the DIS.

DIS election is configured manually.

NO.31 Which of the following statements regarding DIS election is correct?

When the priority is the same, the router with higher IP address will be elected as the DIS.

When a DIS fails, the backup DIS will take over.

The IS-IS router with the highest priority in the whole broadcast network will be elected as the DIS.

DIS election is configured manually.

NO.32 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.

NO.33 Which of the following statements about LAN switch is correct?

LAN switch is transparent for user, it does not modify the data field of the forwarded frame.

LAN switch can still operate normally even when loop exists.

LAN switch can detect loop according to the contents of the packet.

LAN switch can modify the data field of the forwarded frame when necessary.

NO.34 PIM-SM relies on particular unicast routing protocol for RPF check.

True

False

NO.35 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.

NO.36 Which of the following statements are correct?

Both TE FRR and VPN FRR are used to protect tunnels, and therefore they can replace each other.

After VPN FRR is deployed, the end-to-end service convergence time is shorter than 1 second.

TE FRR Implements quick traffic switchovers if a PE becomes faulty.

VPN FRR implements quick traffic switchovers if a PE becomes faulty.

NO.37 What are the main features of the SDN controller?

Centralized networking

Separating the Data Plane and Control Plane

Upgrading Routing Protocols

Open interface
