2.The typical firewall consists of two packet filters and a(an)(68).A．routerB．bridgeC．applicationD．server

3.Which two packet attributes contribute to the identification of a session? ()(Choose two.)A. destination portB. TTLC. IP optionsD. protocol number

4.阅读下面的短文，回答问题 [When an IP packet arrives at a router, generally the router looks at the destination address of the packet, and forwards the packet to one of its network interfaces. The forwarding decision is usually done by looking up the destination address from another data structure called a forwarding table. The forwarding table is created by the router using the routing table and possible routing policies existing in the router. The router then creates a table where it lists which networks are accessible through which of the router’s network interfaces. An IP router looks at every IP packet individually and does the forwarding decision on a packet-by-packet basis. If something changes in the router’s routing table, a packet can take a different route from a preceding packet even if it has the same destination.] From the paragraph above，we can see that the router （ ） a forwarding table according to the routing table and possible routing policies existing in the router. When an IP packet arrives at a router, the （ ） part of packet is normally checked by the router. An IP router checks every IP Packet individually and makes the forwarding decision based on （ ）.A．is generating B．generate C．is generated D．generates A．forwarding table B．network interfaces C．routing policies D．destination address A．the destination address and network interfaces B．forwarding table and network interfaces C．the destination address and forward table D．routing policies and routing table

    ●We have already covered the topic of network addresses. The first(71) in a block (in classes A,B,and C) defines the network address. In classes A,B,and C,if the hostid is all ls, the address is called a direct broadcast address. It is used by a (72) to send a packet to all hosts in a specific network. All hosts will accept a packet having this type of destination address. Note that this address can be used only as a (73)address in an lP packet. Note also that this special address also reduces the number of available hostid for each netid in classes A,B,and C.

    In classes A,B,and C,an address with all Is for the netid and hostid (32 bits) defines a( 74) address in the current network.A host that wants to send a message to every other host can use this address as a destination address in an IP packet.
