Compared with VPLS, what are the characteristics of EVPN?

• A.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.
• B.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.
• C.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.
• D.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.

Which of the statements about BGP UPDATE message are correct?

• A.One UPDATE message can advertise multiple routes at one time, but the path attributes must be the same.
• B.One UPDATE message can include multiple unreachable routes.
• C.BGP uses Update message to implement routing information updating.
• D.One UPDATE message can advertise multiple routes at one time, and the path attributes can be different.

Which of the following statements regarding DIS election is correct?

• A.When a DIS fails, the backup DIS will take over.
• B.DIS election is configured manually.
• C.The IS-IS router with the highest priority in the whole broadcast network will be elected as the DIS.
• D.When the priority is the same, the router with higher IP address will be elected as the DIS.

Which of the following are the functions of route redistribution?

• A.Import static route into dynamic routing protocols
• B.Share routing information found by different routing protocols
• C.Eliminate route loops
• D.Import routes from RIP into OSPF

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

• A.To allocate unique RD for each VPN.
• B.To allocate unique RT for each VPN.
• C.To use different routing protocols In the backbone network for afferent VPN.
• D.To allocate different LSP for each VPN.
• E.To maintain separate VRF lor different VPN.
