Refer to the exhibit． Which WAN protocol is being used? [*] ATM HDLC Frame Relay PPP

Which command can be a router to verify the layer 3 path to a host? traceroute address tracert address ssh address telnet address

Which command reveals the last method used to powercycle a router? show reload show boot show running-config show version

On corporate network, hosts on the same VLAN can communicate with each other, but they are unable to communicate with hosts on different VLANs． What is needed to allow communication between the VLANs? a router with subinterfaces configured on the physical interface that is connected to the switch a router with an IP address on the physical interface connected to the switch a switch with an access link that is configured between the switches a switch with a trunk link that is configured between the switches

A cisco router is booting and has just completed the POST process．It is now ready to find and load an IOSimage．what function does the router perform next? It checks the configuration register It attempts to boot from a TFTP server It loads the first image file in flash memory It inspects the configuration file in NVRAM for boot instructions

Which of these represents an IPv6 link-local address? FE08::280e:611:a:f14f:3d69 FE81::280f:512b:e14f:3d69 FE80::380e:611a:e14f:3d69 FEFE:0345:5f1b::e14d:3d69

Wich command can you use to manually assign a static IPV6 address to a router interface? ipv6 address PREFIX_1::1/64 ipv6 autoconfig 2001:db8:2222:7272::72/64 ipv6 autoconfig ipv6 address 2001:db8:2222:7272::72/64

Which parameter can be tuned to affect the selection of a static route as a backup．when a dynamic protocol is also being used? link bandwidth hop count link cost administrative distance link delay

Refer to the exhibit．The Lakside Company has the internetwork in the exhibit．The administrator would like to reduce the size of routing table on the Central router．Which partial routing table entry in the Central route represents a route summary that represents the vlans in Phoenix but no additional subnets? [*] 10．0．0．0/22 is subnetted,1 subnets D 10．4．0．0[90/20514560] via 10．2．0．2,6w0d,serial0/1 10．0．0．0/28 is subnetted,1 subnets D 10．2．0．0[90/20514560] via 10．2．0．2,6w0d,serial0/1 10．0．0．0/22 is subnetted,1 subnets D 10．0．0．0[90/20514560] via 10．2．0．2,6w0d,serial0/1 10．0．0．0/30 is subnetted,1 subnets D 10．2．2．0[90/20514560] via 10．2．0．2,6w0d,serial0/1 10．0．0．0/28 is subnetted,1 subnets D 10．4．4．0[90/20514560] via 10．2．0．2,6w0d,serial0/1
