When an SRX series device receives an ESP packet, what happens?()
A. If the destination address of the outer IP header of the ESP packet matches the IP address of the ingress interface, it willB. If the destination IP address in the outer IP header of ESP does not match the IP address of the ingress interface, it willC.

Traditional IP packet forwarding analyzes the（ ）IP address contained in the network layer header of each packet as the packet travels from its source to its final destination.A router analyzes the destination IP address independently at each hop in the network.Dynamic（ ）protocols or static configuration builds the database needed to analyze the destination IP address（the routing table）.The process of implementing traditional IP routing also is called hop-by-hop destination-based（ ）routing.Although successful，and obviously widely deployed，certain restrictions，which have been realized for some time，exist for this method of packet forwarding that diminish is（请作答此空）.New techniques are therefore required to address and expand the functionality of an IP-based network infrastructure.This first chapter concentrates on identifying these restrictions and presents a new archiecture，known as multiprotocol（ ）switching，that provides solutions some of these restrictions.
A.reliability
B.flexibility
C.stability
D.capability
考题
If an edge Label Switch Router （LSR） is properly configured，which three combinations are possible？（）A、A received IP packet is forwarded based on the IP destination address and the packet is sent as an IP packet.B、An IP destination exists in the IP forwarding table. A received labeled packet is dropped because the label is not found in the LFIB table.C、There is an MPLS label-switched path toward the destination. A received IP packet is dropped because the destination is not found in the IP forwarding table.D、A received IP packet is forwarded based on the IP destination address and the packet is sent as a labeled packet.E、A received labeled IP packet is forwarded based upon both the label and the IP address.F、A received labeled packet is forwarded based on the label. After the label is swapped，the newly labeled packet is sent.
