A router has learned about a network through static and dynamic routing processes. Which of the following routes will be used to reach network ?A). I [100/8947] via , 00:00:09, Ethernet0B). O [110/1012] via , 00:00:22, Ethernet0C). R [120/1] via , 00:00:17, Ethernet0D). S [1/0] via , 00:00:10, Ethernet031. Refer to the network and routing table entries shown in the graphic. What will happen when a packet destined for network is received by Router A?A). It will be forwarded through interface S1.B). It will be forwarded to the default route.C). It will be directed toward the Internet.D). It will be discarded.32. Which of the following mands can be used to statically configure default routes? (Choose two.)A). ip staticrouteB). ip routeC). ip networkrouteD). ip defaultnetworkE). ip defaultstatic33. Which type of message is generated by a host when the ping mand is entered?A). ICMP echo requestB). ICMP echo replyC). UDP echo requestD). UDP error message34. What happens when an ICMP packet is not deliverable? (Choose two.)A). The packet is dropped.B). An ICMP error message is returned to the original sender.C). An ICMP error message is returned to the original destination.D). An ICMP packet is returned to the nearest router in the path.E). No further ICMP packets are generated as a result of the transaction.35. ACL statements operate in sequential, logical order. If a condition match is true, the rest of the ACL statements are not checked. If all of the ACL statements are unmatched, what happens to the packet?A). The packets will be placed in a buffer and forwarded when the ACL is removed.B). The packets will be sent to the source with an error notification message.C). The implicit permit any statement placed at the end of the list will allow the packets to flow through uninhibited.D). The implicit deny any statement placed at the end of the list will cause the packets to be dropped.36. Which wildcard mask would match the host range for the subnet /26?A). B). C). D). 37. Assuming the ACL in the graphic is correctly applied to an interface, what effect will this ACL have on network traffic?A). Host will be denied ftp access to any destination, but will be permitted all other access.B). All ftp traffic to host will be denied.C). All traffic from that interface will be denied.D). No traffic will be denied because a permit statement does not exist in this ACL.38. A router that has two Ethernet interfaces and one serial interface is configured to route both IP and IPX.
