Question 1A network engineer must configure the router R1 GigabitEthemetl/1 interface to connectto the router R2 GigabitEthemetl/1 interface. For the configuration to be applied theengineer must compress the address 2001:0db8:0000:0000:0500:000a:400F:583B. Whichcommand must be issued on the interface?•A. ipv6 address 2001 db8:0::500:a:4F:583B.B. ipv6 address 2001::db8:0000::500:a:400F:583B•C. ipv6 address 2001:db8::500:a:400F:583Bcorrect•D. ipv6 address 2001:0db8::5:a:4F:583BQuestion 2Which switch technology establishes a network connection immediately when it is pluggedin?•A. PortFastcorrect•B. BackboneFast•C. UplinkFast•D. BPDU guardExplanationPortfast is often configured on switch ports that connect to hosts. Interfaces with Portfast enabled willgo to forwarding state immediately without passing the listening and learning state. Therefore it cansave about 30 to 45 seconds to transition through these states.UplinkFast is a Cisco specific feature that improves the convergence time of the Spanning-TreeProtocol (STP) in the event of the failure of an uplink.Question 3A user configured OSPF in a single area between two routers. A serial interface connectingR1 and R2 is running encapsulation PPP. By default which OSPF network type is seen onthis interface when the user types show ip ospf interface on R1 or R2?•A. point-to-multipoint•B. point-to-pointcorrect•C. broadcast•D. non-broadcastExplanationThe default OSPF network type for HDLC and PPP on Serial link is point-to-point (while the defaultOSPF network type for Ethernet link is Broadcast).Question 4What is the default behavior of a Layer 2 switch when a frame with an unknown destinationMAC address is received?
