answer
Send it out all ports except for the port it was received on.
question
Which of the following are reasons to configure VLANs on a switch as opposed to using switches without VLANs? (Select two.)
answer
Increased security Increased number of broadcast domains
question
Which of the following benefits apply only to creating VLANs with switches and not to segmenting the network with regular switches?
answer
You can create multiple broadcast domains.
question
How many broadcast domains are there in the network shown? http://i.imgur.com/wmOfVie.png
answer
2
question
Which of the following statements describe how VLANs affect broadcast traffic within an internetwork? (Select two.)
answer
Devices on the same VLAN have the same subnet address. Broadcast traffic is transmitted only within a VLAN.
question
Which of the following are true regarding using multiple VLANs on a single switch? (Select two.)
answer
The number of broadcast domains increases. The number of collision domains remains the same.
question
Which of the following best describes the composition of the frame as it travels from A to B?
answer
Computer A sends a normal frame. The first switch appends a VLAN ID to the frame. The second switch removes the VLAN ID before forwarding it to Computer B.
question
Which of the following statements accurately describes a VLAN ID?
answer
Switches append a VLAN ID to the header of each frame to identify the virtual network to which it belongs.
question
A virtual LAN can be created using which of the following?
answer
Switch
question
Which of the following devices should you choose?
answer
Switch
question
Which of the following best describes the concept of a VLAN?
answer
Devices on the same network logically grouped as if they were on the same network.
question
When configuring VLANs on a switch, what is used to identify VLAN membership of a device?
answer
Switch port
question
What should you configure so that the two devices can communicate?
answer
Routing
question
Which of the following technologies should you use to logically isolate the networks?
answer
VLANs
question
Which feature allows the switches to pass VLAN traffic between the switches?
answer
Trunking
question
What should you configure to allow communication between these two devices through the switches?
answer
Trunking
question
When configuring VLANs on a switch, what type of switch ports are members of all VLANs defined on the switch?
answer
Trunk ports
question
When configuring VLANs on a switch, what type of switch ports are members of all VLANs defined on the switch?
answer
Trunk ports
question
Which of the following features dynamically places switch ports in blocking or forwarding states?
answer
Spanning tree
question
Which feature should your switch support?
answer
Spanning tree
question
What problem does the Spanning Tree Protocol prevent?
answer
Switching loops from developing when redundant paths are implemented between switches.
question
Which of the following are advantages of using the Spanning Tree Protocol (STP) in network segmented bridges? (Select three.)
answer
Lets you provide redundancy by using more than one connection between devices, making your network more reliable. Identifies the optimal path between network devices. Prevents switching loops from forming.
question
Which statements accurately describe the port states of both bridges and switches? (Select two.)
answer
Ports in a blocked state still receive BPDUs. In the learning state, the MAC address table can be populated, but frames are not forwarded.
question
What state is it in?
answer
Blocking
question
In what port state are the switches?
answer
Listening
question
Which of the following best describes what the switch will do? (learning)
answer
It uses the source MAC address and network segment information to build its bridge database, but does not forward the message.
question
Which of the following best describes what the switch will do? (listening)
answer
It does not record address or segment information. It does not forward the message.
question
Assuming the default switch configuration, which switch will become the root bridge? http://i.imgur.com/tJ2GOcV.png
answer
B
question
On which ports would you use the portfast command?
answer
Fa0/1 and Fa0/2
question
Assuming the default switch configuration, how can you force switch C to become the root bridge? http://i.imgur.com/7he7snM.png
answer
Configure a priority number of 4096 for switch C.
question
How can you guarantee that switch C becomes the root bridge? http://i.imgur.com/IdHxhfN.png
answer
Configure switch C with a lower priority value.
question
Which protocol should you use?
answer
Rapid PVST+
question
Desirable mode places the port in a negotiating state. Based on the 802.3ad standard. Passive mode places the port into a passive negotiating state. Auto mode places the port into a passive negotiating state. Active mode places the port int a negotiating state.
answer
Port Aggregation Protocol (PAgP) Link Aggregation Control Protocol (LACP) Link Aggregation Control Protocol (LACP)Link Aggregation Control Protocol (LACP) Port Aggregation Protocol (PAgP)
question
Which condition are you most likely to experience on the network?
answer
Collisions
question
Which feature should you implement?
answer
VLANs
