|
STP
|
|
What command will display the forward/filter table?
|
show mac address-table
|
|
What is the result of segmenting a network with a bridge (switch)?
|
It increases the number of collision domains ; It makes smaller collision domains
|
|
Which statement describes a spanning-tree network that has converged?
|
All switch and bridge ports are in either the forwarding or blocking state.
|
|
What is the purpose of Spanning Tree protocol in a switched LAN?
|
To prevent switching loops in networks with redundant paths.
|
|
What are the three distinct functions of layer 2 switching that increase available bandwidth on the network? (3)
|
Address learning ; Forwarding and filtering ; Loop Avoidance
|
|
Your switch has a port status LED that is alternating between green and amber. What does this indicate?
|
The port is experiencing errors.
|
|
A switch creates seperate collision domains but one broad cast domain. A router provides a separate broadcast domain. True or False?
|
True, memorize that shit. You fag.
|
|
What does a switch do when a frame is received on an interface and the destination hardware address is unknown or not in the filter table?
|
Floods the network with the frame looking for the device.
|
|
If a switch receives a frame and the source MAC address is not in the MAC address table but the destination address is, what will the switch do with the frame?
|
Add the source address and port to the MAC address table and forward the frame out the destination port.
|
|
If you want to run the new 802.1w on your switches, which of the following would allowing you run this protocol?
|
Switch(config)#spanning-tree mode 802.1w
|
|
In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN?
|
In an improperly implemented redundant topology.
|
|
Which command was used to produce the following output: MEOW?
|
show mac address-table
|
|
If you want to disable STP on a port connected to a server,which command would you use?
|
spanning-tree portfast
|
|
Layer 2 switching provides which of the following? (4)
|
Hardware-based bridging (ASIC) ; Wire speed ; Low latency ; Low cost
|
|
You need to allow one host to be permitted to attach dynamically to each switch interface. Which two commands must you configure on your catalyst switch to meet this policy?
|
Switch(config-if)#switchport port-security maximum 1 ;switch(config-if)#switchport port-security violation shutdown
|
|
You have two switches connected together with two crossover cables for redundancy, and STP is disabled. Which of the following will happen between the switches?
|
Broadcast storms will occur on the switched network.
