1. NYEDGE1(config)#ipv6 router igrp 1 2. NYEDGE1(config-rtr)#no shutdown 3. NYEDGE1(config-rtr)#int Gi0/0 4. NYEDGE1(config-if)#ipv6 enable 5. NYEDGE1(config-if)#ipv6 eigrp 1
Sequence the steps required to configure router NYEDGE1 for EIGRP with IPv6 and to advertise routes for interface Gi0/0.
Predictability and Easy to configure
Static routing has both benefits and drawbacks when compared to dynamic routing. What are the main benefits of static routing? - Predictability - Easy to configure - Redundancy - Scalability
Show IP route 172.14.0.2
Suppose you configured a static route for 172.14.0.2 and now want to verify that the route is in the routing table. What command is used to view the routes in the routing table? - do ping 172.14.0.2 - ip route 172.14.0.2.255.255.255.0 - ping route 172.14.0.2 - show ip route 172.14.0.2
MAC address of router 2
A packet is traveling from ComputerA to ServerB. What is the source MAC address of the packet as it moves from router R2 to router R3?
Ping
A static route was recently added to your router's routing table. You want to confirm that the IP address for the new static route is reachable. What command would you use to test this? - dig - nslookup - ip route - ping
ipv6 unicast-routing
IPv6 routing is not enabled on routers by default. What command is used to enable IPv6? - ipv6 address - show ip route - ipv6 unnumbered - ipv6 unicast-routing
A floating static rout with an administrative distance higher than the routing protocol configured
Suppose you have concerns of a routing protocol failure on a serial link. What can you implement as a backup route if a failure were to occur in the routing table and would only show in the routing table upon a failure? - A floating static rout with an administrative distance equal to the routing protocol configured - A floating static rout with an administrative distance higher than the routing protocol configured - A floating static rout with an extended ping functionality to work with the routing protocol configured - A floating static rout with an administrative distance lower than the routing protocol configured
0.0.0.0
What address is assigned to the default route in IPv4? - 0.0.0.0 - 255.255.255.255 - 127.0.0.1 - 10.10.10.10
traceroute-ipv6
What command allows you to check the route taken by packets across an IPv6 network? - show ipv6 route - traceroute-ipv6 - ping-ipv6 - show ipv6 traffic

ip route
What command is used to define an explicit path between routers when route information is missing from the routing table? - ip address - debug - show interface - ip route
ipv6 unicast-routing
What command would you use to enable IPv6 routing on your Cisco router? - enable unicast-routing - ipv6 unicast-routing - no ipv6 unicast-routing - enable ipv6
Only the dynamic route
What is displayed in the routing table if a floating static route has been configured and a dynamic route to a destination is also available? - Only the dynamic route - Both the dynamic route and the static route but the dynamic route has an asterisk - Both the dynamic route and the static route are displayed normally - Only the static route
ARP
What is the name of the process that resolves the destination IP address to a MAC address? - ARP - DNS - Routing table - Ping
Longest match
When a router has routes to the same destination, what technique is used first to determine what route to take? - Longest match - Administrative distance - Routing protocol metric - Source IP address
Longest Match
When a router has routes to the same destination, what technique is used first to determine what route to take? - Source IP address - Administrative distance - Routing protocol metric - Longest match
ipv6 route 2001:AC:10:10::1/128 2001:C0:A8:10::3
Which command would you use to configure a house route in IPv6 to next hop address 2001:C0:A8:10::3? - ipv6 route 2001:AC:10:10::1/64 2001:C0:A8:10::3 - ipv6 route 2001:AC:10:10::1/128 2001:C0:A8:10::3 - ipv6 route 2001:AC:10:10::1/128 2001:AC:10:10::1/128 - ip route 2001:AC:10:10::1 2001:c0:a8:10::3

Routing Table
Which feature allows the router to know where to forward a packet it receives? - CDP - ARP table - Routing Table - MAC table
Set the administrative distance higher than 90
