Enter the letter for the matching Answer
incorrect
1.
By default, how often do switches send out BPDU Hellos?
incorrect
2.
A switch receives a frame to be broadcasted. Out what ports is this frame sent?
incorrect
3.
What one-line command would make a switch the root bridge of VLAN 150, regardless of what priority has been set on the other switches in the vlan?
incorrect
4.
What is the purpose of the ForwardDelay value in a BPDU?
incorrect
5.
What command will display the VLAN trunking protocol domain name, password, and whether pruning is enabled?
incorrect
6.
When a switch receives a frame, does it look at the source MAC address, the destination MAC address, or both?
incorrect
7.
Three switches are vying to be the root bridge of VLAN 10. One has a priority of 4196; one has a priority of 8294; the other has the default priority. Which will become the root bridge?
incorrect
8.

incorrect
9.
What term refers to the logical bundling of multiple physical connections between two Cisco switches?
incorrect
10.
What kind of switch port belongs to one VLAN and will carry only that VLAN’s traffic?
incorrect
11.
What Cisco feature allows a port to skip the listening and learning stages of Spanning Tree?
incorrect
12.
What command will display the devices directly connected to a Cisco switch?
incorrect
13.
What can a VTP Server do that a VTP Client cannot?
incorrect
14.
True or False: Portfast is appropriate for use on a port connected to a switch or router.
incorrect
15.
What is a broadcast storm?
incorrect
16.
Switch A is participating in a root bridge election for vlan 1. That switch receives a BPDU from Switch B that contains a lower BID than the one Switch A is sending out. What action will Switch A take?
incorrect
17.
True or False: When VLANs are configured on a Cisco switch, broadcasts between VLANs are still forwarded to ensure connectivity between VLANs.
incorrect
18.
You have several physical connections between two of your Cisco switches. When checking spanning tree statistics, you notice none of the physical port numbers are showing, but you do see an interface called “Po1”. What is this interface?
incorrect
19.
Three physical connections exist between two switches. How does STP view these connections after they are put into one EtherChannel?
incorrect
20.
What is the default trunking mode of a Cisco 2950 switch port?
A.
Switch A will continue to send BPDUs, but these BPDUs will now recognize Switch B as the root bridge.
B.
Show spanning-tree vlan 23, hello time, aging time, forward delay are included as well
C.
The frame is sent out every port except the one on which it was received.
D.
Answer: False. One benefit of VLANs is limiting broadcasts.
E.
The default trunking mode is dynamic desirable, meaning that the port will actively try to create a trunk with the remotely connected port.
F.
An access port belongs to only one VLAN.
G.
Portfast allows a port to skipthe listening and learning stages.
H.
STP views an EtherChannel as a single port, regardless of how many physical connections actually make up the EtherChannel.
I.
EtherChannels combine multiple physical connections into one logical connection.
J.
A VTP server can create, modify, and delete VLANs. A VTP Client cannot.
K.
Show vtp status
L.
A broadcast storm occurs when segments receive broadcasts and respond with broadcasts of their own. The number of broadcasts continues to grow, preventing transmission of unicasts and multicasts
M.
That’s short for “port-channel”, the logical port created when an EtherChannel is created.
N.
Both. The switch looks at the source MAC first to see if an entry needs to be made into the MAC address table, then at the destination MAC to see how to handle the frame.
O.
Show cdp neighbor
P.
Spanning-tree vlan 150 root priority
Q.
The switch with the lowest priority becomes the root bridge. The default priority will be the highest of the three.
R.
False. Portfast should only be used on a port connecting to an enduser device. Using portfast on a port connected to another switch or a router can lead to routing loops.
S.
BPDU Hellos are sent out every two seconds.
T.
The ForwardDelay value indicates how long a port should stay in the listening and learning stages.
Type the Answer that corresponds to the displayed Question.
incorrect
21.
True or False: ISL doesn’t use native VLANs, but dot1q does
incorrect
22.
SW2# Secure Port MaxSecureAddr CurrentAddr SecurityViolation Security Action
incorrect
23.
What port-level command places a switch port into Portfast?
incorrect
24.
What term refers to the ability of VLAN traffic to flow over interconnected switches in the same network?
incorrect
25.
What is the default priority of a Cisco switch?
incorrect
26.
True or False: The lowest BID wins the root bridge election.
incorrect
27.
What command gives you: VTP Version,Configuration Revision,Maximum VLANs supported locally, Number of existing VLANs,VTP Operating Mode,VTP Domain Name, VTP Pruning Mode
