ccna 3 final exam version 1 part 3

31. Refer to the exhibit. An administrator documented the output of a CAM table from an Ethernet switch as shown. What action will the switch take when it receives the frame shown at the bottom of the exhibit?
discard the frame.
forward the frame out port 2.
forward the frame out port 3.
forward the frame out all ports.
forward the frame out all ports except port 3.
add station 00-00-3D-1F-11-05 to port 2 in the forwarding table.

32. Refer to the exhibit. The network administrator wants to configure Switch1 to allow SSH connections and prohibit Telnet connections. How should the network administrator change the displayed confoguration to satisfy the requirement?
Use SSH version 1.
Reconfigure the RSA key.
Configure SSH on a different line.
Modify the transport input comm.and.

33. Refer to the exhibit. The switches have been configured as shown. The hosts that are connected to switch 101-2FL are not able to communicate with the hosts in their corresponding VLANs that are connected to switch 101-3FL. What should be done to fix the problem?
Configure port Fa0/2 on switch 101-3FL as a static trunk link.
Introduce a Layer 3 device or a switch with Layer 3 capability into the topology.
Utilize the switchport trunk allowed vlan all command on switch 101-3FL to permit the VLAN traffic.
Apply IP addresses that are in the same subnet to the interfaces that are used to connect switches 101-2FL and 101-3FL.

34. Refer to the exhibit. Switch SW-A is to be used as temporary replacement for another switch in the VTP Student domain. What two pieces of information are indicated from the exhibited output?(Choose two).
The other switches in the domain can be running either VTP versin 1 or 2.
There is a risk that the switch may cause incorrect VLAN information to be sent through the domain.
VTP will block frame forwarding on at least one redundant trunk port that is configured on this switch.
VLAN configuration changes made on this switch will be sent to other devices in the VTP domain.
This switch will update its VLAN configuration when VLAN changes are made on a VTP server in the same domain.

35. After listening for the presence of a signal on the network media, host A and C transmit data at the same time. In what two ways do the hosts respond to this situation?(Choose two)
The hosts transmit a jam signal to ensure that all hosts on the network are aware that a collision has occured.
Because they are operating in full-duplex mode, the hosts resume listening for traffic in preparation for sending future messages.
Because the hub will temporarily block traffic from one of the hosts, that host will be allowed to transmit once the wire is clear.
Hosts A and C are assigned shorter backoff values to provide them priority to access the media for retransmission.
After the backoff eriod of a host, the host checks to determine if the line is idle before retransmitting.

36. Refer to the exhibit. Which switch will be elected as the root bridge of the spanning tree topology?
Cat-A
Cat-B
Cat-C
Cat-D

37. Which two statements describe Spanning Tree Protocol?(Choose two)
It only used at Layer 2.
It is configured on routers.
It eliminates Layer 2 loops in network topologies.
It limits the number of valid MAC addresses allowed on a port.
It allows VLAN information to propagate to other switches in the network.

38. Which two statements are corect about wireless infrastructure components?(Choose two).
An AP converts the TCP/IP data packets from their 802.11 frame encapsulation format to the 802.3 Ethernet frame format on the wired Ethernet network.
A wireless AP does not require any physical connection to allow wireless clients to access the Internet.
An AP is a layer 2 device, similar to a switch, that provides dediated bandwidth to each connected wireless host.
Collisions do not occur between wireless NICs and APs.
The wireless router performs the roles of AP and router.

39. Refer to the exhibit. A new host needs to be connected to VLAN3. Which IP address should be assigned to this new host?
192.168.1.22/28
192.168.1.31/28
192.168.1.32/28
192.168.1.52/28
192.168.1.63/28

40. A new switch is to be added to an existing network in a remote office. The network administrator does not want the technicians in the remote office to be able to add new VLANs to the switch,but the switch should receive VLAN updates from the VTP domain. Which two steps must be performed to configure VTP on the new switch to meet these conditions?(Choose two.).
Configure an IP address on the new switch.
Configure the existing VTP domain on the new switch.
Configure all ports of both switches to access mode.
Configure the new switch as a VTP client
Enable VTP pruning.

41. Refer to the exhibit. How is port Gi1/1 on SwT-A functioning in the spanning-tree topology?
It is sending and receiving data frames
It is receiving BPDUs, but not sending data frames
It is participating in the election process by forwarding the BPDUs it receives

42. Refer to the exhibit. Sw-T has been configured with a single trunking interface. Which VLANs will be allowed across the trunk?
Only VLAN 1 will be allowed across the trunk.
All configured VLANs will be allowed across the trunk.
Only the native VLAN wil be allowed across the trunk.
Only the the management and native VLANs will be allowed across the trunk.
Only VLANs that are configured on the VTP server in the domain will be allowed across the trunk.

43. Refer to the exhibit.Router RA receives a packet with a source address of 192.168.1.65 and destination address of 192.168.1.161. What will the router do with this packet?
The router will drop the packet.
The router will forward the packet out interface FastEthernet 0/1.1.
The router will forward the packet out interface FastEthernet 0/1.2.
The router will forward the packet out interface FastEthernet 0/1.3.
The router will forward the packet out interface FastEthernet 0/1.2 and interface FastEthernet 0/1.3.

44. Refer to the exhibit. How will switch S2 manage traffic coming from host PC1?
S2 will drop the traffic, unless it is management traffic.
S2 will tag the frame with VLAN ID 99 when it forwards it over the trunk link.
S2 will leave the traffic untagged when it forwards it over a trunk link.
S2 will tag the traffic with the highest VLAN ID value when it forwards it over the trunk link.

45. What is the purpose of VLAN trunking?
It improves network performance by reducing broadcast traffic.
It select the best path to transmit data in a switched network.
It carries the traffic of multiple VLANs through a single link.
It avoids spanning tree loops in a switched network.
