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: BDE
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.

Answer: B
Explanation:
From the CCNA ICND2 Exam book: "Routers decrement the TTL by 1 every time they forward a
packet; if a router decrements the TTL to 0, it throws away the packet. This prevents packets
from rotating forever." I want to make it clear that before the router forwards a packet, the TTL is
still remain the same. For example in the topology above, pings to S0/1 and S0/0 of Router 2
have the same TTL.

switch or bridge. An example for Broadcasting would be DHCP Request from a Client PC. So the client sends a DHCP Discover packet to EVERY PC in the local subnet (Broadcast). The simple way to look at it is this way: switches break up collision domains.com . 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. The number of broadcast domains would remain the same.passexamvce. so when a broadcast hits a router (or the perimeter of a VLAN). don't allow broadcasts through by default. In the old days of hubs. E. but a collision domain can never have more than one broadcast domain associated with it. A collision domain is sometimes referred to as an Ethernet segment. C. http://www. while routers (and VLANs) break up collision domains and broadcast domains. The Client is asking for a IP Address. The number of broadcast domains would decrease. A Router is used to separate Broadcast-Domains (we could also call them Subnets Get Complete Collection of 200-120 Exam's Question and Answers. however. F. Answer: CD Explanation: Basically. Broadcast Domain: Broadcasting sends a message to everyone on the local network (subnet). Broadcast domains are exactly what they imply: they are network segments that allow broadcasts to be sent across them. this meant you had a lot of collisions. you break up collision domains by switching packets bound for other collision domains. and the other devices in the domain listen to the network in order to avoid data collisions. The number of broadcast domains would increase. a broadcast domain can contain multiple collision domains. B. Since switches and bridges allow for broadcast traffic to go unswitched. all these devices are in ONE Broadcast domain (assuming a single VLAN). Routers. it doesn't get forwarded. broadcasts can traverse collision domains freely. The number of collision domains would increase. a collision domain is a network segment that allows normal network traffic to flow back and forth. Also. hub.A. but the client does not know how to reach the DHCP Server. These days. With switches. But only the DHCP Server will answer to the Request. The number of collision domains would decrease. How to count them? Broadcast Domain: No matter how many hosts or devices are connected together. D. 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). The number of collision domains would remain the same. Only one device in the collision domain may transmit at any one time. if they are connected with a repeater. since we mostly use switches to connect computers to the network. you generally have one collision domain to a PC.

Establishing VLANs increases the number of broadcast domains.passexamvce. If a switch receives a frame for an unknown destination. we have one collision domain more. QUESTION 14 Where does routing occur within the DoD TCP/IP reference model? A. Switches that are configured with VLANs make forwarding decisions based on both Layer 2 and Layer 3 address information. Get Complete Collection of 200-120 Exam's Question and Answers. E. each switched segment will contain one root bridge with all its ports in the forwarding state. if a router stands between all these devices. If 5 Devices are connected to a Hub. it uses ARP to resolve the address. Spanning Tree Protocol allows switches to automatically share VLAN information. D. Each network device gets the full bandwidth of the segment and does not have to share the segment with other devices. this is ONE Collision Domain. application internet network transport Answer: B Explanation: The picture below shows the comparison between TCP/IP model & OSI model.com . we have 5 Collision domains. So. B. http://www.. hub) will reside in ONE single collision domain. If this switch is connected to another switch or a router. Microsegmentation reduces and can even eliminate collisions because each segment is its own collision domain -> . All other switches in that broadcast domain will have only one root port. Each device that is connected to a Layer 1 device (repeater. In a properly functioning network with redundant switched paths. F. Note: Microsegmentation decreases the number of collisions but it increases the number of collision domains. if 5 PCs are connected with separate cables to a switch. C. Microsegmentation decreases the number of collisions on the network. D.) A. For example. Collision Domain: Each connection from a single PC to a Layer 2 switch is ONE Collision domain. B. Notice that the Internet Layer of TCP/IP is equivalent to the Network Layer which is responsible for routing decision. C. QUESTION 13 Which three statements accurately describe Layer 2 Ethernet switches? (Choose three. Answer: BDE 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.or call them VLANs). we have TWO broadcast domains.

802.1Q native VLAN frames are untagged by default.
802.1Q trunking ports can also be secure ports.
802.1Q trunks can use 10 Mb/s Ethernet interfaces.
802.1Q trunks require full-duplex, point-to-point connectivity.
802.1Q trunks should have native VLANs that are the same at both ends.

Answer: ACE
Explanation:
By default, 802.1Q trunk defined Native VLAN in order to forward unmarked frame. Switches can
forward Layer 2 frame from Native VLAN on unmarked trunks port. Receiver switches will
transmit all unmarked packets to Native VLAN. Native VLAN is the default VLAN configuration of
port. Note for the 802.1Q trunk ports between two devices, the same Native VLAN configuration
is required on both sides of the link. If the Native VLAN in 802.1Q trunk ports on same trunk link
is properly configured, it could lead to layer 2 loops. The 802.1Q trunk link transmits VLAN
information through Ethernet.

Switch3, port fa0/1
Switch3, port fa0/12
Switch4, port fa0/11
Switch4, port fa0/2
Switch3, port Gi0/1
Switch3, port Gi0/2

Answer: C
Explanation:
In this question, we only care about the Access Layer switches (Switch3 & 4). Switch 3 has a
lower bridge ID than Switch 4 (because the MAC of Switch3 is smaller than that of Switch4) so
both ports of Switch3 will be in forwarding state. The alternative port will surely belong to Switch4.
Switch4 will need to block one of its ports to avoid a bridging loop between the two switches. But
how does Switch4 select its blocked port? Well, the answer is based on the BPDUs it receives
from Switch3. A BPDU is superior than another if it has:
1. A lower Root Bridge ID
2. A lower path cost to the Root
3. A lower Sending Bridge ID
4. A lower Sending Port ID
These four parameters are examined in order. In this specific case, all the BPDUs sent by
Switch3 have the same Root Bridge ID, the same path cost to the Root and the same Sending
Bridge ID. The only parameter left to select the best one is the Sending Port ID (Port ID = port
priority + port index). In this case the port priorities are equal because they use the default value,
so Switch4 will compare port index values, which are unique to each port on the switch, and
because Fa0/12 is inferior to Fa0/1, Switch4 will select the port connected with Fa0/1 (of Switch3)
as its root port and block the other port -> Port fa0/11 of Switch4 will be blocked (discarding role).
