Q6. Which feature allows a device to use a switch port that is configured for half-duplex to access the network?

A. CSMA/CD

B. IGMP

C. port security

D. split horizon

Answer: A

Explanation:

Ethernet began as a local area network technology that provided a half-duplex shared channel for stations connected to coaxial cable segments linked with signal repeaters. In this appendix, we take a detailed look at the half-duplex shared-channel mode of operation, and at the CSMA/CD mechanism that makes it work.

In the original half-duplex mode, the CSMA/CD protocol allows a set of stations to compete for access to a shared Ethernet channel in a fair and equitable manner. The protocolu2021s rules determine the behavior of Ethernet stations, including when they are allowed to transmit a frame onto a shared Ethernet channel, and what to do when a collision occurs. Today, virtually all devices are connected to Ethernet switch ports over full-duplex media, such as twisted-pair cables. On this type of connection, assuming that both devices can support the full-duplex mode of operation and that Auto-Negotiation (AN) is enabled, the AN protocol will automatically select the highest-performance mode of operation supported

by the devices at each end of the link. That will result in full-duplex mode for the vast majority of Ethernet connections with modern interfaces that support full duplex and AN.

Q7. When you configure router# ipnat pool 10.10.10.1 10.10.10.20 255.255.255.0

A. nat pool

B. dynamicnat

C. nat translation

D. dhcp pool

Answer: B

Q8. CORRECT TEXTThere are three locations in a school district of a large city: ROUTER -M, ROUTER -W and ROUTER -U. The network connection between two of these locations has already functioned. Configure the ROUTER -M router IP addresses on the E0 and S0 interfaces so that the E0 receives the first usable subnet while the S0 receives the second usable subnet from the network 192.168.160.0/28. Both interfaces would receive the last available ip address on the proper subnet.

NotE. The OSPF process must be configured to allow interfaces in specific subnets to participate in the routing process.

Answer:

ROUTER-M> enable PassworD. Cisco

ROUTER-M# config t

ROUTER-M(config)# interface e0

ROUTER-M(config-if)# ip address 192.168.160.14 255.255.255.240

ROUTER-M(config-if)# no shutdown

ROUTER -M(config-if)# exit

ROUTER -M(config)# interface s0

ROUTER-M(config-if)# ip address 192.168.160.30 255.255.255.240

ROUTER-M(config-if)# no shutdown

ROUTER-M(config-if)# end

ROUTER-M# copy run start
