ATrue
BFalse
On a medium-sized network configured with BGP, two RRs are typically deployed to improved BGP RR reliability. Typically, the cluster IDs of the two RRs are set as the same. Which of the following is the reason for that?
ATo prevent loops.
BTo prevent sub-optimal routes.
CTo prevent memory insufficiency caused by receiving too many routes on RRs.
DTo prevent memory insufficiency caused by receiving too many routes on clients.

On the network shown in the following figure, 802.1X authentication is deployed on GE0/0/1 of SW2. Which of the following statements are correct?
AWhen MAC address-based access control is used, 802.1X clients A and B must be authenticated separately before they can obtain corresponding network access permissions.
BWhen interface-based access control is used, 802.1X client B can use network resources without being authenticated if 802.1X client A is successfully authenticated.
CAssume that SW2 uses MAC address-based access control mode and 802.1X client A passes authentication first. If 802.1X client A goes offline first, then 802.1X client B will still have the corresponding network access permissions because the interface status remains unchanged.
DAssume that SW2 uses the interface-based access control mode and 802.1X client A passes authentication first. If 802.1X client A goes offline first, then 802.1X client B will lose the corresponding network access permissions.
As shown in the figure, Site1 and Site2 need to communicate through a carrier's BGP/MPLS IP VPN. A public network tunnel has been established between PE1 and PE2 (label information is shown in the figure). PE1 has advertised the 192.168.1.0/24 route of Site1 to PE2 through MP-IBGR and route learning is normal. What is the top label in a data packet transmitted on the link P -> PE1 if the packet is sent by Site2 to 192.168.1.0/24 of Site1?
A3

Which of the following statements regarding forwarding equivalence class (FEC) in MPLS are incorrect? (Choose all that apply.)
APackets with the same FEC are processed differently on a MPLS network.
BFECs can be divided flexibly by source IP address destination IP address, source port, destination port, protocol type, VPN, or any combinations of them.
CMPLS classifies packets with the same forwarding processing mode into one FEC.
DOne FEC has only one unique label marker.
The following figure shows the inter-AS MPLS L3VPN Option C (solution 2). ASBR-PE2 is connected to CE3 and runs EBGP. To enable all CEs to communicate with each other, in which of the following address families must peer relationships be enabled in the BGP process of ASBR-PE2? (Choose all that apply.)
AVPNv4 address family
BUnicast BGP address family
CVPN instance unicast address family
DBGP-LS address family
Which of the following statements are correct about the topology shown in the figure? (Choose all that apply.)
APC1 and PC2 have different masks, so they cannot communicate with each other.
BPC1 and PC2 have different masks, but this does not necessarily cause a communication failure.
CPC1 and PC2 are associated with the same BD, so they can communicate with each other.
DPC1 and PC2 are associated with the same BD but have different VNIs, so they cannot communicate with each other.
The RR is critical to the Huawei SD-WAN Solution, and its deployment mode varies based on the scenario. In which of the following modes can an RR be deployed? (Choose all that apply.)
