SSH encrypts all remote management communications whereas Telnet does not.
SSH sends a clear text message steam which reduces the bandwidth use for management.

Host A remains a member of VLAN 10, because the switch provides dynamic VLAN assignment for the port.
Host A maintains connectivity to all members of VLAN 10, because it is connected to the same physical network.

The switch port is configured for auto duplex and the PC is configured for full duplex. What will commonly cause this problem?
The PC is set to full duplex. The switch port fails to autonegotiate the duplex setting and defaults to half duplex, which causes a duplex mismatch.

The PC and the default gateway have different bandwidth Ethernet ports.
The default gateway is not on the same switch that the PC is.

Router interface Fa0/0 is possibly down.
No routing protocol is configured on Router1.

43. After unpacking a new Linksys WRT300N wireless multifunction device, a user needs to change the default administrator password
    and make other configuration changes. What must the user doto access the device in order to make these changes?

Use a wireless client to associate with the WRT300N and then open a HyperTerminal sssion with the device
Establish a wired connection with the device and then reboot the attached computer to launch the configuration software
***Establish a wired connection from a computer in the same IP subnet as the WRT300N and enter the default IP address of the device into a web browser on the computer
Modify the TCP/IP properties of the computer that is connected to the WRT300N so that the computer and the WRT300N exist on the same network. Then reboot computer to establish a connection

44. 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

45. Which statements correctly describes the function of a Layer 2 switch?

***It performs switching and filtering based on the destination network layer address
    It automatically uses STP to prevent switching loops in redundant topologies
    It uses VTP to allow data from multiple VLANs to travel across a single link
    It routes packets between different LAN segments



46. 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

47. Which statement correctly describes the spanning-tree path cost?

It is calculated based on the total number of switches connected in a loop
It is calculated based on the utilization of all the switches along a given path
***It is calculated based on the bridge priority of the switches along a given path
It is calculated based on the sum of the port cost value, determited by link speed, for each switch port along a given path

48. 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

49. Refer to the exhibit. What is the purpose of the configuration commands that are shown?

to activate port Fa0/10
***to make the port a member of VLAN 30
to activate port security on port Fa0/10
to add VLAN 30 to the trunk that is connected to port Fa0/10

50. Refer to the exhibit. Router R-West and switch S-West1 are connected via a single ethernet cable between the router interface fa0/0 and the switch interface fa0/1. The router and switch have been configured with the commands that are displayed in the exhibit. The network administrator enters the show interfaces trunk command and receives the output as shown. What is the cause of the "not-trunking" status for switch port Fa0/1?

The trunk is established, but no VLANs have been configured to
use it
The router is missing the dynamic trunking protocol statements
necessary to form a trunk
***Because the router does not support Dynamic Trunking Protocol,
the trunk has not been established
The router, the switch, or both must be configured with the
 dynamic desirable option for Dynamic Trunking Protocol to
 establish a trunk
more.
