A. FALSE

B. TRUE

A. An MCE device creates a routing table for each VPN and binds each VPN instance to it's interfaces

B. Based on the interface for receiving routing information, the MCE determines the origin of the routing information and adds the routing information to the routing table of the corresponding VPN

C. The MCE can connect to multiple VPNs. The MCE solution isolates services of different VPNs while reducing the cost of network devices

D. The MCE has been bound to a VPN. Therefore, no VPN needs to be bound to the PE connected to the MCE

A. The router will send its own IBGP BGP IBGP EBGP neighbor update to its neighbors and neighbors.

B. IBGP Loopback neighbors can pass through the interface to establish a relationship

C. EBGP neighbors are connected to neighbors and must be connected to physical interface addresses.

D. EBGP EBGP-Multi-hop neighbors must be connected. Otherwise, it must be configured

E. The router will send its own EBGP BGP IBGP EBGP neighbor update to its neighbors and neighbors.

F. IBGP IBGP-Multi-hop neighbors must be connected. Otherwise, it must be configured

A. In inter-AS VPN Option A mode, the routes advertised between two ASBRs are common IPv4 routes.

B. In inter-AS VPN Option C solution 2, if only LDP is used to advertise public network labels, three labels need to be used during packet forwarding.

C. In inter-AS VPN Option B mode, an MP-EBGP peer relationship needs to be established between two ASBRs.

D. In inter-AS VPN Option B mode, two ASBR-PEs are interconnected through multiple interfaces (including sub-interfaces), each interface is associated with one VPN, and each ASBR-PE considers the remote device as a CE.

A. Upper data layer

B. Network Department

C. Path record

D. net tail layer

E. Data Road Department Chain Head

A. Forward delay

B. Hold time

C. Root cost

D. Hello time

E. Max Age

A. WRED selectively discards multiple TCP flows to avoid global synchronization.

B. WRED can be used to set different drop thresholds and packet loss ratio for data packets with different priorities.

C. Traffic with low bandwidth is more likely to be discarded than traffic with high bandwidth.

D. When traffic exceeds the minimum threshold, WRED starts to discard all inbound traffic (tail drop).

A. Sparse Mode

B. Source tree

C. Shared tree

D. Dense Mode

E. PIM bidirectional

F. Dense Tree

A. A Type5 route carries a Layer 3 VNI

B. The IP prefix field in a Type5 route can carry either the host IP address or the network segment address

C. A Type5 route carries both Layer 2 and Layer 3 VNIs

D. Type5 route is the IP prefix route
