Refer to the exhibit. A network administrator tries to test the connectivity between routers R1 and R2, but the attempt to ping is unsuccessful. Based on the show ip interface brief command outputs, what could be the possible cause of the problem? Interface S0/0/0 on router R1 is shut down. Interface S0/0/0 on router R1 is configured with an incorrect IP address. Interface S0/0/0 on router R2 is administratively down. Interface S0/0/0 on router R2 does not have the clock rate settings configured.

Refer to the exhibit. RouterB is configured properly. The Ethernet interface Fa0/0 of RouterA is configured with the use of the co that are shown. However, a ping from the Fa0/0 interface of RouterA to the Fa0/0 interface of RouterB is unsuccessful. What act should be taken on RouterA to solve this problem? Use the description command on the FastEthernet interface Fa0/0. Configure the clock rate of the FastEthernet interface Fa0/0. Use the no shutdown command on the FastEthernet interface Fa0/0. Reboot the router.Final del formulario

Refer to the exhibit. Host C is able to ping 127.0.0.1 successfully, but is unable to communicate with hosts A and B in the organi What is the likely cause of the problem? Hosts A and B are not on the same subnet as host C.

The IP addresses on the router serial interfaces are wrong. The subnet mask on host C is improperly configured. The FastEthernet interface fa0/0 of router 1 is wrongly configured.Final del formulario

Refer to the exhibit. While configuring a network, a technician wired each end of a Category 5e cable as shown. Which two state are true about this setup? (Choose two.) The cable is suitable for connecting a switch to a router Ethernet port. The cable is suitable for connecting dissimilar types of devices. The cable is unusable and must be rewired. The cable is terminated in a way that the transmit pin is wired to the receive pin. The cable simulates a point-to-point WAN link.Final del formulario

15

Principio del formulario

Refer to the exhibit. The ping 127.0.0.1 command is issued on the local host. What do the ping results indicate? The local host can send packets on the local network. The TCP/IP stack on the local host operates properly. The local host has full connectivity to the default gateway. The local host has full connectivity to the remote network.Final del formulario

Refer to the exhibit. Host A is configured with the correct IP address for the default gateway of the router R1 FastEthernet0/1 inte How will a packet that is sent from host A to host B be handled by the devices on the network? R1 will drop the packet because R1 does not have a specific route in its routing table to the 10.1.1.0/24 network.

R1 will forward the packet to its default gateway, the next hop router R2. R2 will forward the packet to the directly connecte network 10.1.1.0/24.

R1 will forward the packet to its default gateway, the next hop router R2. R2 will drop the packet because it does not have a route to network 10.1.1.0/24.

R1 will forward the packet to its default gateway, the next hop router R2. R2 will drop the packet because it does not have a that is learned by a routing protocol to network 10.1.1.0/24.
