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.128x.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.

C. this meant you had a lot of collisions. you break up collision domains by switching packets bound for other collision domains. With switches. F.) A. so when a broadcast hits a router (or the perimeter of a VLAN). don't allow broadcasts through by default. The number of broadcast domains would increase. Broadcast domains are exactly what they imply: they are network segments that allow broadcasts to be sent across them. Answer: C. Routers. The number of broadcast domains would decrease.D Explanation: Basically. a collision domain is a network segment that allows normal network traffic to flow back and forth.Certification Guaranteed 12 .Cisco 200-125 : Practice Test What two results would occur if the hub were to be replaced with a switch that is configured with one Ethernet VLAN? (Choose two. 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). you generally have one collision domain to a PC. D. however. B. Since switches and bridges allow for broadcast traffic to go unswitched. In the old days of hubs. These days. E. The number of broadcast domains would remain the same. since we mostly use switches to connect computers to the network. The number of collision domains would increase. broadcasts can traverse collision domains freely. The simple way to look at it is this way: A Composite Solution With Just One Click . The number of collision domains would decrease. it doesn't get forwarded. The number of collision domains would remain the same.

we have 5 Collision domains. while routers (and VLANs) break up collision domains and broadcast domains. we have TWO broadcast domains. How to count them? Broadcast Domain: No matter how many hosts or devices are connected together. but a collision domain can never have more than one broadcast domain associated with it. If 5 Devices are connected to a Hub. a broadcast domain can contain multiple collision domains. Each device that is connected to a Layer 1 device (repeater. hub) will reside in ONE single collision domain. A collision domain is sometimes referred to as an Ethernet segment. Broadcast Domain: Broadcasting sends a message to everyone on the local network (subnet).or call them VLANs). The Client is asking for a IP Address. Also. but the client does not know how to reach the DHCP Server.) A Composite Solution With Just One Click . So the client sends a DHCP Discover packet to EVERY PC in the local subnet (Broadcast). if 5 PCs are connected with separate cables to a switch.Cisco 200-125 : Practice Test switches break up collision domains. and the other devices in the domain listen to the network in order to avoid data collisions. For example. Question No : 11 DRAG DROP . A Router is used to separate Broadcast-Domains (we could also call them Subnets .Certification Guaranteed 13 . Only one device in the collision domain may transmit at any one time. we have one collision domain more. if a router stands between all these devices. hub. (Not all options are used. if they are connected with a repeater. this is ONE Collision Domain. all these devices are in ONE Broadcast domain (assuming a single VLAN). But only the DHCP Server will answer to the Request. Collision Domain: A group of Ethernet or Fast Ethernet devices in a CSMA/CD LAN that are connected by repeaters and compete for access on the network. So. Collision Domain: Each connection from a single PC to a Layer 2 switch is ONE Collision domain. switch or bridge.(Topic 1) Drag the cable type on the left to the purpose for which it is best suited on the right.

each switched segment will contain one root bridge with all its ports in the forwarding state. Spanning Tree Protocol allows switches to automatically share VLAN information. Microsegmentation decreases the number of collisions on the network.Certification Guaranteed 17 . E.E Explanation: Microsegmentation is a network design (functionality) where each workstation or device on a network gets its own dedicated segment (collision domain) to the switch.) A. All other switches in that broadcast domain will have only one root port. This is a port on a network interface card in a PC.Cisco 200-125 : Practice Test D. C. Switches that are configured with VLANs make forwarding decisions based on both Layer 2 and Layer 3 address information. In a properly functioning network with redundant switched paths. Each network device gets the full bandwidth of the segment and does not have to share the segment with other devices. F. D. Establishing VLANs increases the number of broadcast domains.(Topic 1) Which three statements accurately describe Layer 2 Ethernet switches? (Choose three. Question No : 15 . B. Answer: C Explanation: Modern Ethernet networks built with switches and full-duplex connections no longer utilize CSMA/CD. Microsegmentation reduces and can even eliminate collisions because each segment is its own collision domain ->.D. This is an Ethernet port operating at full duplex. Answer: B. A Composite Solution With Just One Click . it uses ARP to resolve the address. Note: Microsegmentation decreases the number of collisions but it increases the number of collision domains. E. If a switch receives a frame for an unknown destination. CSMA/CD is only used in obsolete shared media Ethernet (which uses repeater or hub).

the MAC address of host A Answer: A Explanation: Whereas switches can only examine and forward packets based on the contents of the MAC header. What will be the source MAC address of the frames received by Host A from the server? A. These network-layer headers contain source and destination network addresses. After receiving the packets. Host A is communicating with the server. Check the incoming packet for corruption. the router must perform the following steps: 1. the MAC address of router interface e1 C.(Topic 1) Refer to the graphic. routers can look further into the packet to discover the network for which a packet is destined. Routers make forwarding decisions based on the packet's networklayer header (such as an IPX header or IP header). the MAC address of router interface e0 B. Local devices address packets to the router's MAC address in the MAC header.Cisco 200-125 : Practice Test Question No : 16 . The router then strips off the MAC header and examines the network-layer header to determine what to do with the packet. and remove the MAC header. A Composite Solution With Just One Click .

For example.Cisco 200-125 : Practice Test 2. the router discards the packet. the router must build a new header. 15 hops is the maximum number of hops (or routers) that a packet can cross. Question No : 17 DRAG DROP . IPX headers contain a hop count. IP headers contain a Time to Live (TTL) value. the router builds a new MAC header for the packet. Drag the correct frame and packet address to their place in the table. A router cannot decrement the TTL value to 1 and then forward the packet. A Composite Solution With Just One Click . After determining which direction to forward the packet. Consider the packets as they leave RouterA interface Fa0/0 towards RouterB. Routers maintain a routing table that lists available networks. The MAC header includes the router's MAC address and the final destination's MAC address or the MAC address of the next router in the path. which increments as the packet is forwarded through each router. If an IP packet has a TTL value of 1. 3. (If you want to read the IP routing tables on a Windows 95/98 workstation. Examine the age of the packet. the IP TTL value decrements as the IP packet is forwarded through each router. By default. type ROUTE PRINT in the DOS box. PC_1 is sending packets to the FTP server.

there are 7 collision domains in this exhibit (6 collision domains between hubs & switches + 1 collision between the two switches). RSTP port states are blocking.D Explanation: One big disadvantage of STP is the low convergence which is very important in switched network. RSTP expands the STP port roles by adding the alternate and backup roles. These ports are allowed to immediately enter the forwarding state rather than passively wait for the network to converge. C.B.) A. RSTP significantly reduces topology reconverging time after a link failure. or forwarding. While STP can take 30 to 50 seconds to transit from a blocking state to a forwarding state. Answer: A. which significantly reduces the convergence time after a topology change occurs in the network. learning. F. the IEEE with document 802. discarding. RSTP also uses the STP proposal-agreement sequence.(Topic 2) Which three statements about RSTP are true? (Choose three. in 2001. The alternative port moves to the forwarding state if there is a failure on the designated port for the segment. For your information. To overcome this problem. RSTP bridge port roles: * Root port – A forwarding port that is the closest to the root bridge in terms of path cost * Designated port – A forwarding port for every LAN segment * Alternate port – A best alternate path to the root bridge. RSTP is typically able to respond less than 10 seconds of a physical link failure. Question No : 68 . RSTP works by adding an alternative port and a backup port compared to STP. E.1w introduced an evolution of the Spanning Tree Protocol: Rapid Spanning Tree Protocol (RSTP). RSTP provides a faster transition to the forwarding state on point-to-point links than STP does. This path is different than using the root port. RSTP uses the same timer-based process as STP on point-to-point links. * Backup port – A backup/redundant path to a segment where another bridge port already A Composite Solution With Just One Click .

SwitchD. Switch C has lowest MAC address so it will become root bridge and 2 of its ports (Fa0/1 & Fa0/2) will be designated ports. In general. Now let’s have a look at the topology again A Composite Solution With Just One Click . Gi0/2. SwitchC. “cost” is calculated based on bandwidth of the link. 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. Fa0/2. root F. the lower the value of its cost. The higher the bandwidth on a link. 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. The receiving switch will add its local port cost value to the cost in the BPDU.F Explanation: The question says “no other configuration changes have been made” so we can understand these switches have the same bridge priority.B. 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. 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.Certification Guaranteed 65 . root Answer: A. Because SwitchC is the root bridge so the 2 ports nearest SwitchC on SwitchA (Fa0/1) and SwitchD (Gi0/2) will be root ports.Cisco 200-125 : Practice Test E.

Now our last task is to identify the port roles of the ports between SwitchA & SwitchB. It is rather easy as the MAC address of SwitchA is lower than that of SwitchB so Fa0/2 of SwitchA will be designated port while Gi0/2 of SwitchB will be alternative port. The same process happens for SwitchA and SwitchB learns that it can reach SwitchC via Gi0/2 with a total cost of 23 -> Switch B chooses Gi0/1 as its root port ->.Certification Guaranteed 66 . SwitchB adds another 4 and learns that it can reach SwitchC via Gi0/1 port with a total cost of 8. Switch D adds 4 (the cost value of 1Gbps link) and advertises this value (4) to SwitchB. Below summaries all the port roles of these switches: A Composite Solution With Just One Click .Cisco 200-125 : Practice Test SwitchC advertises its cost to the root bridge with a value of 0.

A network administrator needs to configure port security on a switch. Which two statements
are true? (Choose two.)
A. The network administrator can apply port security to dynamic access ports.
B. The network administrator can apply port security to EtherChannels.
C. When dynamic MAC address learning is enabled on an interface, the switch can learn
new addresses, up to the maximum defined.
D. The sticky learning feature allows the addition of dynamically learned addresses to the
running configuration.
E. The network administrator can configure static secure or sticky secure MAC addresses
in the voice VLAN.
Answer: C,D
Explanation:
Follow these guidelines when configuring port security:
+ Port security can only be configured on static access ports, trunk ports, or 802.1Q tunnel
ports.
+ A secure port cannot be a dynamic access port.
+ A secure port cannot be a destination port for Switched Port Analyzer (SPAN).
+ A secure port cannot belong to a Fast EtherChannel or Gigabit EtherChannel port group.
+ You cannot configure static secure or sticky secure MAC addresses on a voice VLAN.
+ When you enable port security on an interface that is also configured with a voice VLAN,
you must set the maximum allowed secure addresses on the port to at least two.
+ If any type of port security is enabled on the access VLAN, dynamic port security is
automatically enabled on the voice VLAN.
+ When a voice VLAN is configured on a secure port that is also configured as a sticky
secure port, all addresses seen on the voice VLAN are learned as dynamic secure
addresses, and all addresses seen on the access VLAN (to which the port belongs) are
learned as sticky secure addresses.
+ The switch does not support port security aging of sticky secure MAC addresses.
+ The protect and restrict options cannot be simultaneously enabled on an interface.

What can be done to secure the virtual terminal interfaces on a router? (Choose two.)
A. Administratively shut down the interface.
B. Physically secure the interface.
C. Create an access list and apply it to the virtual terminal interfaces with the access-group
command.
D. Configure a virtual terminal password and login process.
E. Enter an access list and apply it to the virtual terminal interfaces using the access-class
command.
Answer: D,E
Explanation:
It is a waste to administratively shut down the interface. Moreover, someone can still
access the virtual terminal interfaces via other interfaces ->
We cannot physically secure a virtual interface because it is “virtual” ->.
To apply an access list to a virtual terminal interface we must use the “access-class”
command. The “access-group” command is only used to apply an access list to a physical
interface -> C is not correct.
The most simple way to secure the virtual terminal interface is to configure a username &

Explanation:

A simple way to find out which layer is having problem is to remember this rule: “the first
statement is for Layer 1, the last statement is for Layer 2 and if Layer 1 is down then surely
Layer 2 will be down too”, so you have to check Layer 1 before checking Layer 2. For
example, from the output “Serial0/1 is up, line protocol is down” we know that it is a layer 2
problem because the first statement (Serial0/1 is up) is good while the last statement (line
protocol is down) is bad. For the statement “Serial0/1 is down, line protocol is down”, both
layers are down so the problem belongs to Layer 1.
There is only one special case with the statement “…. is administrator down, line protocol is
down”. In this case, we know that the port is currently disabled and shut down by the
administrators.

What Netflow component can be applied to an interface to track IPv4 traffic?
A. flow monitor
B. flow record
C. flow sampler
D. flow exporter
Answer: A
Explanation:
Flow monitors are the Flexible NetFlow component that is applied to interfaces to perform
network traffic monitoring. Flow monitors consist of a record and a cache. You add the
record to the flow monitor after you create the flow monitor. The flow monitor cache is
automatically created at the time the flow monitor is applied to the first interface. Flow data
is collected from the network traffic during the monitoring process based on the key and
nonkey fields in the record, which is configured for the flow monitor and stored in the flow
monitor cache.
For example, the following example creates a flow monitor named FLOW-MONITOR-1 and
enters Flexible NetFlow flow monitor configuration mode:

When an interface is configured with PortFast BPDU guard, how does the interface
respond when it receives a BPDU?
A. It continues operating normally.
B. It goes into a down/down state.
C. It becomes the root bridge for the configured VLAN.
D. It goes into an errdisable state.
Answer: D
Explanation: Understanding How PortFast BPDU Guard Works To prevent loops from
occurring in a network, the PortFast mode is supported only on nontrunking access ports
because these ports typically do not transmit or receive BPDUs. The most secure
implementation of PortFast is to enable it only on ports that connect end stations to
switches. Because PortFast can be enabled on nontrunking ports connecting two switches,
spanning tree loops can occur because BPDUs are still being transmitted and received on
those ports.
PortFast BPDU guard prevents loops by moving a nontrunking port into an errdisable state
when a BPDU is received on that port. When you enable BPDU guard on the switch,
spanning tree shuts down PortFast-configured interfaces that receive BPDUs instead of
putting them into the spanning tree blocking state. In a valid configuration, PortFastconfigured interfaces do not receive BPDUs. If a PortFast-configured interface receives a
BPDU, an invalid configuration exists. BPDU guard provides a secure response to invalid

During which phase of PPPoE is PPP authentication performed?
A. the PPP Session phase
B. Phase 2
C. the Active Discovery phase
D. the Authentication phase
E. Phase 1
Answer: A
Explanation: PPPoE is composed of two main phases:
Active Discovery Phase: In this phase, the PPPoE client locates a PPPoE server, called
an access concentrator. During this phase, a Session ID is assigned and the PPPoE layer
is established.
PPP Session Phase: In this phase, PPP options are negotiated and authentication is
performed. Once the link setup is completed, PPPoE functions as a Layer 2 encapsulation
method, allowing data to be transferred over the PPP link within PPPoE headers.

The client is responsible for passing user information to designated RADIUS servers. authenticating the user. ✑ A server. and then acting on the response that is returned.(Topic 8) Which statement about RADIUS security is true? A. RADIUS comprises three components: ✑ A protocol with a frame format that utilizes User Datagram Protocol (UDP)/IP. Physical security procedures may be the least expensive to implement but can also be the most costly if not implemented. Network Security Transactions between the client and RADIUS server are authenticated through the use of a shared secret.Cisco 200-125 : Practice Test is critical that each party to the network take appropriate measures to ensure that its system will not be physically breached. It is a system of distributed security that secures remote access to networks and network services against unauthorized access.1 and later and other device software. Client/Server Model A network access server (NAS) operates as a client of RADIUS. B. any user passwords are sent encrypted between the client and RADIUS server. The most expensive and sophisticated computer protection software can be overcome once an intruder obtains physical access to the network. In addition. Cisco has incorporated the RADIUS Client into Cisco IOS Software Release 11. This eliminates the possibility that someone snooping on an unsecured network could determine a user's password. It supports EAP authentication for connecting to wireless networks. while the clients reside in the dial-up access servers and can be distributed throughout the network. The RADIUS servers can act as proxy clients to other kinds of authentication servers. Answer: A Explanation: RADIUS Background RADIUS is an access server that uses AAA protocol. When it is provided with the user name and original password given by the user. ✑ A client.
