考题
The routers named Testking1 and Testking2 are both configured with RIP only.What will happen in the event of Testking1 receiving a routing update that contains a higher cost path to a network already in its routing table?（）A. The update information will be added to the existing routing table.B. The update information will replace the existing routing table entry.C. The update will be ignored and thus no further action will occur.D. The existing routing table entry will be purged from the routing table and all routers will attempt convergence.
考题
Which two are advantages of static routing when compared to dynamic routing?()
A.Security increases because only the network administrator may change the routing tablesB.Configuration complexity decreases as network size increasesC.Routing updates are automatically sent to neighborsD.Route summarization is compued automatically by the routerE.Routing traffic load is reduced when used in stub network linksF.An efficient algorithm is used to build routing tables,using automatic updatesG.Routing tables adapt automatically to topology changes.
考题
Which two statements are true regarding EIGRP?()
A. Passiveroutes are in the process of being calculated by DUAL.B. EIGRP supports VLSM, route summarization, and routing update authentication.C. EIGRP exchanges full routing table information with neighboring routers with every update.D. If the feasible successor has a higher advertised distance than the successor route, it becomes the primary route.E. A query process is used to discover a replacement for a failed route if a feasible successor is not identified from the current routing information.

考题
Routing convergence time is which of the following？（）A、Time required for a VPN connection to occurB、Time required by protocols to update their forwarding tables after changes have occurredC、Time required for an IDS to detect suspicious softwareD、Time required by switch ports to update their link status and transition to the forwarding state
考题
On AIX systems， where DNS resolution takes precedence over NIS， a particular process needs to resolve names using /etc/hosts first. Which of the following processes is the best way to accomplish this without affecting the rest of the system’s name resolution？（）A、Set the NSORDER environmental variable of the environment which invokes the process to：NSORDER="local，nis，bind"B、Set the NSORDER environmental variable of the environment which invokes the process to： NSORDER="hosts=auth，nis，bind"C、Edit /etc/netsvc.conf to add a line similar to the following： process /full/path/of/process {hosts=local，nis，dns}D、Unset NSORDER environment variable of the environment which invokes the process
