select the statement that best describes a broadcast storm.

A Broadcast storm occurs when there are so many broadcast messages on the network that they approach or exceed the network bandwidth..

A switch running STP is a backup bridge. What state is it in?

Blocking

Which of the following statements describe how VLANs effect broadcast traffic within an internetwork?

Devices on the same VLAN have the same subnet address Broadcast traffic is transmitted only within a VLAN Which of the following are true

Which of the following best describes the concept of a VLAN?

Devices on the same network logically grouped as if they were on separate networks

A user reports that network access from her workstation is very slow. The problem does not seem to be affecting any other users. Which of the following conditions is the most likely cause?

Duplex mismatch

You manage a network with multiple switches. You find that your switches are experiencing heavy broadcast storms. Which of the following will help reduce the effects of a broadcast storm?

Enable spanning tree on the switches

You manage a local area network with several switches. A new employee has started today so you connect her workstation to a switch port.Which of the following is the most likely cause of the problem?

Incorrect VLAN assignment

Which of the following statements accurately describes how a modem works? (Select Two.)

It demodulates analog data from a telephone network into digital PC data. It modulates digital data from the PC into analog data and transmits it on a telephone network.

A switch running STP is in the listening state. A message destined for a different network segment arrives at the switch. Which of the following best describes what the switch will do?

It does not record the address or segment information. It does not forward the message

A switch running STP is in a learning state. A message destined for a different network segment arrives at the switch. Which of the following best describes what the switch will do?

It uses the source MAC address and network segment information to build its bridge database, but does not forward the message

Which statements accurately describes port states of both bridges and switches?

Ports in a blocked state still receive BPDUs\ In the learning state the MAC address table can be populated, but frames not forwarded.

Which of the following are advantages of using the Spanning Tree Protocol (STP) in network segmented bridges?

Prevents message loops from forming Identifies the optimal path between network devices. Lets you provide redundancy by using more then one connection between devices, making your network more reliable.

You need to configure spanning tree on a Cisco switch. You'd like to use a protocol that confirms to the 802.1w standards. Which protocol should you use?

Rapid PVST+

A switch receives a frame addressed to the MAC address FF:FF:FF:FF:FF:FF.What will the switch do with the frame?

Send it out all ports except for the port it was received on

Which of the following features dynamically places switch ports in blocking or forwarding states?

Spanning tree

You manage a single subnet with three switches. The switches are connected to provide redundant paths between the switches. Which feature prevents switching loops and ensures there is only a single active patch between any two switches?

Spanning tree

You want to reduce collisions by creating separate collision domains and virtual LANs. Which of the following devices should you choose?

Switch

When configuring VLANs on a switch, what is used to identify VLAN membership of a device?

Switch port

Which of the following connectivity hardware is used to create a VLAN?

Switch.

Which of the following statements accurately describes a VLAN ID?

Switches append a VLAN ID to the header of each frame to identify the virtual network to which it belongs

What problem does the Spanning Tree protocol prevent?

Switching loops from developing when redundant paths are implemented between switches.

Which of the following are true using multiple VLANS on a single switch? select two

The number of broadcast domains increases The number of collision domains remain the same

While viewing the status of the interfaces on a Cisco switch, you see abnormally large of oversized ethernet frames being received on one interface. This interface is connected to a workstation located on the 2nd floor What could be causing this to happen?

The workstation's network board is jabbering

When configuring VLANs on a switch, what type of switch ports are members of all VLANs defined on the switch?

Trunk Ports

You manage a network with two switches. The switches are connected together through their Gigabit Ethernet uplink ports. You define VLAN 1 and VLAN 2 on each switch. A device on the first switch in VLAN 1 needs to communicate with a device on the second switch also in VLAN 1. What should you configure to allow communication between these two devices through the switches?

Trunking

You manage a single subnet with three switches. The switches are connected to provide redundant paths between the switches. Which feature allows the switches to pass VLAN traffic between the switches?

Trunking

You run a small network for your business that has a single router connected to the Internet and a single switch. You keep sensitive documents on a computer that you would like to keep isolated from other computers on the network. Other hosts on the network should not be able to communicate with this computer through the switch, but you still need to access the network through the computer. What should you use for this situation?

VLAN

Which of the following benefits apply only to creating VLANs with switches and not to segmenting the network with regular switches?

You can create multiple broadcast domains.

You manage a network with a single switch. On each switch port, a hub connects multiple devices to the switch. which condition are you most likely to experience on the network ?

collisions

Switches running the STP are in the process of exchanging BPDUs and defining their roles. In what state are the switches?

listening

Which of the following solutions would you implement to eliminate switching loops?

spanning tree
