Refer to the exhibit. A network administrator has configured a network after subnetting the network number 192.168.0.0/28. Workstation 1 is not able to communicate with Workstation 2. What is the cause of this loss in communications?

Workstation 1 and Workstation 2 are on the same subnet.

The serial connections are using addresses from the LAN subnets.

Workstation 1 is not on the same network that the Router 1 LAN interface is on.

If routers are used in the network, IP addresses do not need to be subnetted.

1. How does a router decide where the contents of a received frame should be forwarded?

by matching destination IP addresses with networks in the routing table

by matching the destination IP address with IP addresses listed in the ARP table

by matching the destination MAC address with MAC addresses listed in the CAM table

by forwarding the frame to all interfaces except the interface on which the frame was received

 

2. Which device would add security to a network by not forwarding broadcasts?

hub

router

switch

Refer to the exhibit. Which two statements are correct in reference to the output shown? (Choose two.)

The LAN segment is subnetted to allow 254 subnets.

The DNS server for this host is on the same subnet as the host.

The host automatically obtained the IP addresses 192.168.1.100.

The host received the IP address from a DHCP-enabled device on the local LAN segment.

The host is assigned an address of 00-50-8D-F1-EA-8D by the administrator.

1. How does 1000BASE-T use the UTP wire pairs to accomplish transmission?

two pairs are used to transmit and two pairs are used to receive

one pair is used to transmit, one pair is used to receive, one pair is used for clocking, and one pair is used for error correction

all four pairs are used in parallel by both hosts to transmit and receive simultaneously

two pairs of wires are used as in 10BASE-T and 100BASE-TX
