B.the AVG router,replying with a different AVF MAC address each time
C.a random AVF router,based on a GLBP seed hash key
D.only the AVG router that received the ARP request first

B.It will inspect IP packets that are encapsulated in tunnels, such as GRE,LT2P,or PPTP.
C.uRPF is performed within the CEF switching path.

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)?()
A. PG-R3 will receive up to four queries for 192.168.1.0/24, one each from PG-R2, PG-R4, PGR5,and PG-R6.
B. PG-R3 will receive up eight queries for 192.168.1.0/24, one from PG-R2, two from PG-R4,three from PG-R5, and four from PG-R6.
C. PG-R3 will receive one query for 192.168.1.0/24, since the remote routers, PG-R4, PG-R5, and PG-R6, are natural stubs in EIGRP.
D. PG-R3 will not receive any queries from PG-R2, because there are no alternate paths for 192.168.1.0/24.

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?()

Two routers configured to run BGP have been connected to a firewall, one on the inside interface and one on the outside interface.

What is agood first test to see if BGP will work across the firewall?()
