• Router(config)#line vty 0 4

• Router(config-if)#line console 0

• Router(config)#line vty all

Which two of the following are true regarding the distance-vector and link-state routing protocols?

• Link state sends its complete routing table out all active interfaces on periodic time intervals

• Distance vector sends its complete routing table out all active interfaces on periodic time intervals.

• Link state sends updates containing the state of their own links to all routers in the internetwork

• Distance vector sends updates containing the state of their own links to all routers in the internetwork.

Which two of the following commands will place network 10.2.3.0/24 into area 0?

Select all that apply

• router eigrp 10

• router ospf 10

•  network 10.2.3.0 0.0.0.255 area 0

• network 10.0.0.0

Which of the following is an addressing type that is assigned to network interfaces for communications on the physical network segment?

• Router ID

•  Bridge ID

• MAC address

•  IP address

What routing protocol supports unequal cost load-balancing?

• EIGRP

• STP

• OSPF

• RIPv2

Why is VLSM important to modern IP networks?

• Because networks that use the same mask cannot route.

•  Because every subnet must use a different mask to avoid conflicts.

• Because it allows us to uniquely identify each subnet by its mask number

•  Because it allows each subnet in a routed system to be correctly sized for the requirement.

Which command is used to allow everyone in the network in EIGRP?

• Network 255.255.255.240

• Network from all
