Which three statements correctly describe Network Device A? (Choose three.)

A. With a network wide mask of 255.255.255.128, each interface does not require an IP address.
B. With a network wide mask of 255.255.255.128, each interface does require an IP address on a
unique IP subnet.
C. With a network wide mask of 255.255.255.0, must be a Layer 2 device for the PCs to
communicate with each other.
D. With a network wide mask of 255.255.255.0, must be a Layer 3 device for the PCs to
communicate with each other.
E. With a network wide mask of 255.255.254.0, each interface does not require an IP address.

Answer: B,D,E
Explanation: If Subnet Mask is 255.255.255.128 the hosts vary from x.x.x.0 - x.x.x.127 &
x.x.x.128- x.x.x.255,so the IP Addresses of 2 hosts fall in different subnets so each interface
needs an IP an address so that they can communicate each other.

If Subnet Mask is 255.255.255.0 the 2 specified hosts fall in different subnets so they need a
Layer 3 device to communicate.

If Subnet Mask is 255.255.254.0 the 2 specified hosts are in same subnet so are in network
address and can be accommodated in same Layer 2 domain and can communicate with each
other directly using the Layer 2 address.

The number of collision domains would remain the same. broadcasts can traverse collision domains freely. These days. Broadcast domains are exactly what they imply: they are network segments that allow broadcasts to be sent across them. "Pass Any Exam. so when a broadcast hits a router (or the perimeter of a VLAN). a broadcast domain can contain multiple collision domains. The number of collision domains would increase. Since switches and bridges allow for broadcast traffic to go unswitched. since we mostly use switches to connect computers to the network.) A. Routers. F. you break up collision domains by switching packets bound for other collision domains." . The number of broadcast domains would remain the same. With switches. D. The simple way to look at it is this way: switches break up collision domains. a collision domain is a network segment that allows normal network traffic to flow back and forth. Also. don't allow broadcasts through by default. and the old CSMA/CD would be working overtime to try to get those packets re-sent every time there was a collision on the wire (since ethernet allows only one host to be transmitting at once without there being a traffic jam). Answer: C. it doesn't get forwarded. while routers (and VLANs) break up collision domains and broadcast domains. Cisco 200-120 Exam What two results would occur if the hub were to be replaced with a switch that is configured with one Ethernet VLAN? (Choose two.

Refer to the exhibit.

Based on the information given, which switch will be elected root bridge and why?

A. Switch A, because it has the lowest MAC address
B. Switch A, because it is the most centrally located switch
C. Switch B, because it has the highest MAC address
D. Switch C, because it is the most centrally located switch
E. Switch C, because it has the lowest priority
F. Switch D, because it has the highest priority

Answer: E
Explanation:
To elect the root bridge in the LAN, first check the priority value. The switch having the lowest
priority will win the election process. If Priority Value is the same then it checks the MAC Address;
the switch having the lowest MAC Address will become the root bridge. In this case, switch C has
the lowest MAC Address so it becomes the root bridge.

C. when they detect no other devices are sending
D. when the medium is idle

"Pass Any Exam. Any Time." - www.actualtests.com 19

Cisco 200-120 Exam
E. when the server grants access

Answer: C,D
Explanation: Explanation
Ethernet network is a shared environment so all devices have the right to access to the medium. If
more than one device transmits simultaneously, the signals collide and can not reach the
destination.

If a device detects another device is sending, it will wait for a specified amount of time before
attempting to transmit.

When there is no traffic detected, a device will transmit its message. While this transmission is
occurring, the device continues to listen for traffic or collisions on the LAN. After the message is
sent, the device returns to its default listening mode.

A. Switch-1 will drop the data because it does not have an entry for that MAC address.
B. Switch-1 will flood the data out all of its ports except the port from which the data originated.
C. Switch-1 will send an ARP request out all its ports except the port from which the data
originated.
D. Switch-1 will forward the data to its default gateway.

Answer: B
Explanation:
This question tests the operating principles of the Layer 2 switch. Check the MAC address table of
Switch1 and find that the MAC address of the host does not exist in the table. Switch1 will flood
the data out all of its ports except the port from which the data originated to determine which port
the host is located in.

Switches work as follows:

What is the function of the command switchport trunk native vlan 999 on a Cisco Catalyst switch?

"Pass Any Exam. Any Time." - www.actualtests.com 31

Cisco 200-120 Exam
A. It creates a VLAN 999 interface.
B. It designates VLAN 999 for untagged traffic.
C. It blocks VLAN 999 traffic from passing on the trunk.
D. It designates VLAN 999 as the default for all unknown tagged traffic.

Answer: B
Explanation:
Configuring the Native VLAN for Untagged Traffic

A trunk port configured with 802.1Q tagging can receive both tagged and untagged traffic. By
default, the switch forwards untagged traffic in the native VLAN configured for the port. The native
VLAN is VLAN 1 by default.

B. 802.1w
C. 802.1D
D. 802.1Q

Answer: D
Explanation: Explanation
Dynamic Trunking Protocol (DTP) is a Cisco proprietary protocol for negotiating trunking on a link
between two devices and for negotiating the type of trunking encapsulation (802.1Q) to be used.

QUESTION NO: 40

Which of the following are benefits of VLANs? (Choose three.)

A. They increase the size of collision domains.
B. They allow logical grouping of users by function.
C. They can enhance network security.
D. They increase the size of broadcast domains while decreasing the number of collision domains.
E. They increase the number of broadcast domains while decreasing the size of the broadcast
domains.
F. They simplify switch administration.

Answer: B,C,E
Explanation: Explanation
When using VLAN the number and size of collision domains remain the same ->
VLANs allow to group users by function, not by location or geography -> .
VLANs help minimize the incorrect configuration of VLANs so it enhances the security of the
network -> .
VLAN increases the size of broadcast domains but does not decrease the number of collision
domains ->
VLANs increase the number of broadcast domains while decreasing the size of the broadcast
domains which increase the utilization of the links. It is also a big advantage of VLAN -> .
VLANs are useful but they are more complex and need more administration ->

One more thing to notice is that a root bridge always advertises the cost to the root bridge (itself) with an initial value of 0. Below are the cost values you should memorize: SwitchB will choose the interface with lower cost to the root bridge as the root port so we must calculate the cost on interface Gi0/1 & Gi0/2 of SwitchB to the root bridge. In general." . The receiving switch will add its local port cost value to the cost in the BPDU. “cost” is calculated based on bandwidth of the link. the lower the value of its cost. This can be calculated from the “cost to the root bridge” of each switch because a switch always advertises its cost to the root bridge in its BPDU. Now we come to the most difficult part of this question: SwitchB must have a root port so which port will it choose? To answer this question we need to know about STP cost and port cost.

Answer: D Explanation: Explanation The PVC STATUS displays the status of the PVC. and is waiting for interesting traffic to trigger a call to the remote router. This status is rarely seen so it is ignored in some books. There are 4 statuses: + ACTIVE: the PVC is operational and can transmit data + INACTIVE: the connection from the local router to the switch is working. The PVC is configured correctly and is operating normally. The DCE device creates and sends the report to the DTE devices. but the connection to the remote router is not available + DELETED: the PVC is not present and no LMI information is being received from the Frame Relay switch + STATIC: the Local Management Interface (LMI) mechanism on the interface is disabled (by using the “no keepalive” command).actualtests.
