Which two statements about SA caching are true？（）

Which types of prefixes will a router running BGP most likely advertise to an IBGP peer， assuming it is notconfigured as a route reflector？（）

Spanning Tree Protocol IEEE 802.1 s defines the ability to deploy which of these？（）

What is also called Type 0 authentication in OSPF on Cisco Routers？（）

Based on the output provided in the exhibit， to which address or location will the router forward a packet sent to 192.168.32.1？（）

An expanding company is deploying leased lines between its main site and two remote sites. Thebandwidth of the leased lines is 128kb/s each，terminated on different serial interfaces on the main router.These links are used for combined VOIP and data traffic. The network administrator has implemented a VOIP solution to reduce costs，and has therefore reserved sufficient bandwidth in a low latency queue oneach interface for the VOIP traffic. Users now complain about bad voice quality although no drops areobserved in the low latency queue. What action will likely fix this problem？（）

On the basis of the network provided in the exhibit， all routers are configured to run EIGRP on all links. If the link between PG-R1 and PG-R2 fails， what is the maximum number of queries PG-R3 will receive for 192.168.1.0/24， assuming that all the packets sent during convergence are transmitted once （there are no dropped or retransmitted packets）？（）

Which two statements are true about RED？（）

Which two EIGRP options will limit a query domain？（）

Which three message types are valid PIMv2 message types？（）
