17,in an effort to decrease the size of the routing tables in the TestKing network, summarization is being configured on all routers. where in an EIGRP network is it most appropriate to implement route summarization?
a.at area border routers
b.at autonomous system boundary routers
c.it is done automatically by the DR router in each area
d.manually at any interface of any EIGRP router within the network
e.in backbone area routers
answer:b
18,EIGRP sends hello packets every 5 seconds on high bandwidth links and every 60 seconds on low bandwidth multipoint links. the hold time is typically three times the hello interval. on slow NBMA media, hold time will be 180 seconds
19,EIGRP use the DUAL algorithm, not the Djikstra's algorithm.the Djikstra algorithm is used by distance vector protocols. EIGRP is considered to be a hybrid routing protocol
20,By default, cisco routers will automatically summarize EIGRP routes across major network boundaries. with EIGRP, you can configure a summary aggregate address for a specified interface. if there are any more specific routes in the routing table, EIGRP will advertise the summary address out the interface with a metric equal to the minimum of all more specific routes
21,what action does an EIGRP router take when it cannot find a feasible successor for a network?
a.it examines the routing and neighbor tables for the next best path
b.it transitions from passive to active state for that network and queries its neighbors

d.it transitions from active to passive state for the next network and queries its neighbors
answer:b
22,which of the following statements regarding OSPF and VLSM support are true?

b.summarization can be performed with different prefix lengths throughout the network
c.the use of VLSM enable s truly hierarchical addressing scheme to be developed
d.OSPF's support for VLSM does not compensate for its inability to handle discongiguous subnets
answer:b,c
23,OSPF is considered to be an extremely scalable routing protocol.which of the following would be reasons for this?
a.neighbor adjacencies control distribution of routing protocol updates
b.routing table information does not flood the network until holddown timers have expired
c.the hello protocol is a more effcient means of sending routing updates than table exchange used in RIPv1
d.topological database is maintained with incremental updates, with full exchange occruring only every 30 minutes
answer:a,d
24,with which other routers on an ethernet LAN should the DROTHER routers form OSPF full adjacency?
the DR and BDR only
25,if the dead timer shows that the neighbor relationships have already been established, so the state will be full for all neighbors, and since the OSPF priorities are all set to 1,the router with the highest router ID will be the DR
26,which of the three areas below are valid OSPF area types?

ordinary area(standard area),stub area,totally stubby area,not so stubby area,backbone area(area 0)
27,what does Cisco recommend for those who set up networks with multiple OSPF areas?
a.there should not be more than three areas per route
b.area 0 must be larger than any subsequent OSPF area
c.a router can be a DR or BDR for more than one LAN
d.you should not run more than one instance of the OSPF process on an ABR

29,youa re the administrator of the large TestKing OSPF and area considering dividing it to multiple areas.what are two advantages of configuring multiple OSPF areas?
a.it eliminates the need for a DR or BDR in the OSPF network
b.it eliminates security concerns by segregating portions of the network
c.type 1 and 2 LSAs are confined to a single area, reducing routing overhead
d.area members have smaller topological databases than if the network was one large area, requiring less CPU to derive routes
answer:c,d

44,when configuring routers in a NBMA topology,subinterfaces are typically used. a physical interface can be split into multiple logical interfaces,called subinterfaces,with each subinterface being defined as point-to-multipoint interface. subinterfaces originally were created to better handle issues caused by split horizon over NBMA and distance vector-based routing protocols
