（A）It pops the MPLS label and forwards the packet to the next IP router.

（B）It forwards the packet to the next LSR without altering the MPLS label.

（C）It pushes a new MPLS label and forwards the packet to the next LSR.

（D）It swaps the MPLS label and forwards the packet to the next LSR.

（A）Each VPRN service maintains a separate VPN routing and forwarding instance to separate customer routing information.

（B）You cannot have overlapping IP addresses. The service provider must ensure that its customers are all using discrete IP address space.

（C）A VPRN will ignore IP addressing information and use MAC addressing instead which are always unique.

（D）A VPRN will translate customer IP addresses to a private addressing scheme administered by the service provider.

（A）IS-IS

（C）Ethernet

（D）OSPF

（E）BGP

（A）9 broadcast domains, 3 collision domains.

（B）1 broadcast domain, 9 collision domains.

（C）3 broadcast domains, 9 collision domains.

（D）3 broadcast domains, 3 collision domains.

（A）A device that receives and retransmits a signal out its ports, but does not do any Layer 2 analysis of the data.

（B）A device that receives a signal and based on the Layer 3 destination address, makes a decision on which ports the signal should be retransmitted.

（C）A passive device simply used to connect two or more cables. Does not generate or amplify any signals.

（D）A device that receives a signal and based on the Layer 2 destination address, makes a decision on which ports the signal should be retransmitted.

（A）208.40.224.65 - 208.40.224.78

（B）208.40.224.17 - 208.40.224.30

（A）To provide an address that refers to a specific group of devices in a network.

（B）To provide an address that refers to a group of devices having the same IP address in different Layer 2 domains.

（C）To provide an address that refers to a single device on a given subnetwork.

（D）To provide an address that refers to all the IP devices in a given subnetwork.

（A）Real-time audio application such as VoIP.

（B）Telnet.

（C）Web browser.

（D）Email application.

（B）It should connect to at least one other PE router.

（C）It is not aware of the VPN services provided by the service provider.

（D）It resides on the customer premises.

（A）Unicast.

（B）Multicast.

（C）Broadcast.

（D）Anycast.

（A）Explicitly defines the next hop based on operator input.

（B）Can only be used for routing within an autonomous system.

（C）Uses a hop-count metric to determine the best route to a network.

（D）Responds in real time to network failures.

（A）Ethernet

（B）FTP

（C）TCP

（D）IP

（A）An autonomous system is a network or group of networks operating under one administrative authority.

（B）An autonomous system is another term for the collection of routers that make up the Internet

（C）An autonomous system is a loosely defined term that can refer to any organization that has a connection to the Internet.

（D）An autonomous system is a network or group of networks from many organizations running different IGP routing protocols, but all running BGP.

（A）Digital Equipment Corporation.

（B）Apple Computer.

（C）DEC-Intel-Xerox.

（D）Intel Corporation.

（E）IBM.

（A）False

（B）True

（A）R3 discards the LSA received from R2 and sends a copy of the LSA from its link state base to R2.

（B）R3 installs the LSA received from R2 in its link state database and floods a copy to its neighbors.

（C）R3 installs the LSA received from R2 in its link state database, sends an ACK to R2, and floods a copy to its neighbors.

（D）R3 discards the LSA received from R2 and sends an ACK to R2.

（A）The MDA converts data from its incoming physical format into an internal format and provides some minimal buffering.

（B）The MDA contains the flexible fast path complex used for forwarding data.

（C）The MDA buffers data and applies Quality of Service (QoS) to classify and treat the data appropriately.

（D）Excess data is discarded by the MDA and the remaining data forwarded for QoS processing.
