What occurs when a PC with the IP address 10.1.1.27/28 needs to communicate with a PC that has IP address 10.1.1.18? (Choose two.)
It sends the frame to its default gateway.
It sends the frame directly to the destination PC.
It uses ARP to get the MAC address of the default gateway.
It uses ARP to get the MAC address of the destination PC.

Which of the following are true when using EUI-64? (Choose two.)
The interface MAC address is used unmodified.
The interface MAC address is used with FFFE added to the middle.
The seventh bit from the left in the MAC address is flipped.

What command is used on a Cisco IOS router to enable SLAAC on an interface?
ipv6 address autoconfig
ipv6 address dhcp
ipv6 address prefix eui-64
ipv6 nd ra suppress
Which of the following are requirements for stateless address autoconfiguration to function? (Choose three.)
The prefix must be /64.
The router must be sending and not suppressing RA messages.
The router must be enabled for IPv6 unicast routing.
The router must be sending RS messages.
Which command is used to enable a router to inform clients that they need to get additional configuration information from a DHCPv6 server?
ipv6 nd ra suppress
ipv6 dhcp relay destination
ipv6 address autoconfig
ipv6 nd other-config-flag
What command enables you to configure a router interface as a DHCPv6 relay agent?

Which two data structures reside at the router’s data plane? (Choose two.)
IP routing table
ARP cache
Forwarding Information Base
Adjacency table
Which command enables you to verify routes in the FIB?
show ip route
show ip arp
show ip cef
show adjacency detail
Which of the following populate a routing protocol’s data structure, such as the EIGRP topology table? (Choose three.)
Updates from a neighbor
Redistributed routes
Interfaces enabled for the routing process
Static routes
Which of the following has the lowest default administrative distance?
OSPF
EIGRP (internal)
RIP
eBGP
What is the default administrative distance of an OSPF intra-area route?
90
110
115
120
Your router has learned about the 10.0.0.0/24 network from EIGRP, OSPF, and IS-IS. What is the administrative distance of the source protocol that the router will install in the routing table to reach 10.0.0.0/24?
90
110
115
120
Your router has learned about the 10.0.0.0/24 network from EIGRP, OSPF, and IS-IS. You need the route learned from IS-IS installed in the routing table. What do you need to do?
Nothing because IS-IS will be installed by default.
Increase the administrative distance of the IS-IS route to 121.
Increase the administrative distance of the EIGRP route to 116.
Reduce the administrative distance of the IS-IS route to 80.
How can you create a floating static route?
Provide the static route with a metric higher than the preferred source of the route.
Provide the static route with a metric lower than the preferred source of the route.
Provide the static route with an AD higher than the preferred source of the route.
Provide the static route with an AD lower than the preferred source of the route.
What occurs when you create an IPv4 static route with an Ethernet interface designated instead of a next-hop IP address?
The router uses ARP to get the MAC address of the directly connected router’s IP address.
The router forwards the packet with the destination MAC address FFFF:FFFF:FFFF.
The router uses ARP to get the MAC address of the IP address in the source of the packet.
The router uses ARP to get the MAC address of the IP address in the destination of the packet.
