1 Bandwidth can be conserved by reducing the periodic distribution of Link State Packets (LSPs) so regular updates are exchanged only at some specified time interval. Why is it passible to do this without causing the convergence time to increase dramatically? A Sequence number can be used on LSPs B Time stamps can be included in the LSPs C Network topology changes trigger immediate LSP updates D Each router's entire routing table can be passed to neighboring routers
2 When setting up RIP routing on a Cisco router.the network command contains no information about the subnets connected to the route ,only the class A,B,and C network addresses.Where does the router get this information?
A This information is not used. RIP updates for all subnets are sent to each subnet B The touter "learns" which subnets are connected to each interface as the routing tables are populated C If subnetting is used,the information must be entered for each router interface with the ip subnet command. D The ip address command with IP addresses and subnet masks allows RIP to determine which subnets are connected to this router
3 What are the disadvantages fo connection-oriented network communications compared to connectionless service?(2个答案) A Static-path selection B Dynamic-path selection C Data throughput is not guaranteed D Static reservation of network resources E Packert may arrive at their destination out of order
