Quiz 11
You can create multiple broadcast domains

Spanning tree
Which of the following features dynamically places switch ports in blocking or forwarding states?
Spanning tree
Which of the following solutions would you implement to eliminate switching loops?
Switches append a VLAN ID to the header of each frame to identify the virtual network to which it belongs.
Which of the following statements accurately describes a VLAN ID?
Switching loops from developing when redundant paths are implemented between switches.
Which problem does the spanning tree protocol prevent?
Ports in a blocked state still receive BPDUs In the learning state, the MAC address table can be populated, but frames are not forwarded
Which statements accurately describe the port states of both bridges and switches? (Select two)
The workstation's network board is jabbering
While viewing the status of the interfaces on a Cisco switch, you see an abnormally large number of oversized Ethernet frames being received on the interface. This interface is connected to a workstation located on the second floor. What could cause this to happen?
It uses the source MAC address and network segment information to build its bridge database, but does not forward the message.
A switch is running STP is in the 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?
Blocking
A switch running STP is classified as a backup bridge. What state is it in?
It does not record address or segment information. It does not forward the message
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?
Duplex mismatch
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?
Desirable mode places the port in a negotiating state- Port Aggregation Protocol (PAgP) Based on the 802.3ad standard- Link Aggregation Control Protocol (LACP) Auto mode places the port into a passive negotiating state- Port Agregation Protocol (PAgP) Active mode places the port in a negotiating state- Link Aggregation Control Protocol (LACP)
Match the Ethernet protocol
Listening
Switches running STP are in the process of exchanging BPDUs and redefining their roles. Which port state are the switches currently in?
A broadcast storm occurs when there are so many broadcast messages on the network that they approach or exceed the network bandwidth
Select the statement that best describes a broadcast storm
Show running-config interface Show interface
The network board in a workstation is currently configured as follows: -Network Speed = Auto -Duplexing = Auto The workstation is experiencing poor network performance, and you suspect that the network board is not correctly detecting the network speed and duplex settings. Upon investigation, you find that it is running at 10 Mbps half-duplex. You know that your network switch is capable of much faster throughout. To fix this issue, you decide to manually configure these settings on the workstation. Before you do so, you need to verify the configuration of the switch port that the workstation is connected to. Given that it is a Cisco switch, which commands can be used on the switch to show a list of all switch ports and their current settings? (Select two)
Incorrect VLAN assignment
You manage a local area network with several switches. A new employee has started today, so you connect her workstation to a switch port. After connecting the workstation, you find that the workstation cannot get an IP address from the DHCP server. You check the link and status lights and see that the connecting is working properly. A ping to the loopback address on the workstation succeeds. No other computers seem to have the problem. Which of the following is most likely the cause of the problem?
VLANs
You manage a network that uses a single switch. All ports within your building connect through the single switch. In the lobby of your building are three RJ-45 ports connected to the switch. You want to allow visitors to plug into these ports to gain Internet access, but they should not have access to any other devices on your private network. Employees connected throughout the rest of your building should have both private and Internet access. Which feature should you implement?
Spanning tree
You manage a network that uses multiple switches. You want to provide multiple paths between switches so that if one link goes down, an alternate path is available. What feature should your switch support?
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
Computers A and B are on the same VLAN and are separated by two switches as shown in the exhibit. Computer A sends a frame to Computer B. Which of the following best describes the composition of the frame as it travels from A to B?
Trunk ports
When configuring VLANs on a switch, what type of switch ports are members of all VLANs defined on the switch?
Configure a priority number of 4096 for switch C
You have just connected four switches as shown in the Exhibit. Assuming the default switch configuration, how can you force switch C to become the root bridge?
B
You have just connected four switches as shown in the Exhibit. Assuming the default switch configuration, which switch will become the root bridge?
Configure switch C with a lower priority value
You have three switches configured as shown in the Exhibit. How can you guarantee that switch C becomes the root bridge?
2
You have two switches connected together as shown in the following diagram. How many broadcast domains are in the network shown?
Collisions
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?
Enable spanning tree on the switches
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?
Trunking
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?
Spanning tree
You manage a single subnet with three switches. The switches are connected to provide redundant paths between the switches. What feature prevents switching loops and ensures there is only a single active path between any two switches?
Rapid PVST+
You need to configure spanning tree on a Cisco switch. You'd like to use a protocol that conforms to the 802.1w standards. Which protocol should you use?
VLAN
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?
