Answer

Associate with the access point and then open a HyperTerminal session with the access point.

Answer

Physically connect to the access point and then reboot the computer to launch the configuration software.

Answer

From a computer in the same IP subnet as the access point, enter the default IP address of the access point in a web browser.

Answer

Modify the TCP/IP properties of the computer connected to the access point so that it exists on the

Answer

Per VLAN Spanning Tree (PVST)

Answer

Per VLAN Spanning Tree + (PVST+)

Answer

Common Spanning Tree (CST)

Answer

Rapid Spanning Tree Protocol (RSTP)

Answer

Multiple Spanning Tree Protocol (MSTP)

Answer

The PC and the default gateway have different bandwidth Ethernet ports.

Answer

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.

Answer

The switch traffic is exceeding available frame buffers. The result is that frames are being dropped.

Answer

The default gateway is not on the same switch that the PC is.

Answer

AS1 and AS2

Answer

DS1 and DS2

Answer

DS1, DS2, and CS1

Answer

AS1, AS2, DS1, and DS2

Answer

Answer

One of the router subinterfaces is possibly down.

Answer

Available bandwidth is reduced

Answer

MAC addresses are easily spoofed.

Answer

APs are more susceptible to DoS attacks.

Answer

The payload encryption is easily broken.

Answer

Interface FastEthernet3/0/0 is subinterfaced.

Answer

A non-proprietary trunking protocol is in use.

Answer

The configuration is appropriate for a router-on-a-stick network design.

Answer

A shutdown command has been applied to interface FastEthernet3/0/0.

Answer

Interface FastEthernet3/0/0.3 is mapped to the default management VLAN.

Answer

An IP address should be applied to FastEthernet3/0/0 for correct data routing.

Answer

only the management VLAN

Answer

all VLANs except the extended range VLANs

Answer

all VLANs except 1 and 1002-1005

Answer

It propagates VLAN configurations to other switches.

Answer

It restricts broadcast packets to a single VLAN.

Answer

It segments a network into multiple broadcast domains.

Answer

It prevents loops in a switched network with redundant paths.

Answer

The command should have been copy startup-config tftp:backup.cfg.

Answer

A backup configuration from a TFTP server cannot be copied directly into the startup-config.

Answer

The command copy running-config startup-config should be used to save the changes on the switch.

Answer

Downloading to the startup-config requires the switch to be reloaded in order for the configuration to take effect.

Answer

discard the frame

Answer

forward the frame out port 2

Answer

forward the frame out all ports

Answer

forward the frame out all ports except port 3
