New CCNA – Switch Questions
Question 1
Refer to the exhibit.
Switch-1 needs to send data to a host with a MAC address of 00b0.d056.efa4. What will Switch-1 do with this data?
A. Switch-1 will drop the data because it does not have an entry for that MAC address.
B. Switch-1 will forward the data to its default gateway.
C. Switch-1 will flood the data out all of its ports except the port from which the data originated.
D. Switch-1 will send an ARP request out all its ports except the port from which the data originated.
Answer: C
Explanation
The MAC address of 00b0.d056.efa4 has not been learned in its MAC address table so Switch-1 will broadcast the frame out all of its ports except the port from which the data originated.
Question 2
A technician has installed SwitchB and needs to configure it for remote access from the management workstation connected SwitchA. Which set of commands is required to accomplish this task?
A.
SwitchB(config)#interface FastEthernet 0/1
SwitchB(config)#ip address 192.168.8.252 255.255.255.0
SwitchB(config)#no shutdown
B.
SwitchB(config)#ip default-gateway 192.168.8.254
SwitchB(config)#interface vlan 1
SwitchB(config)#ip address 192.168.8.252 255.255.255.0
SwitchB(config)#no shutdown
C.
SwitchB(config)#interface vlan 1
SwitchB(config)#ip address 192.168.8.252 255.255.255.0
SwitchB(config)#ip default-gateway 192.168.8.254 255.255.255.0
SwitchB(config)#no shutdown
D.
SwitchB(config)#ip default-network 192.168.8.254
SwitchB(config)#interface vlan 1
SwitchB(config)#ip address 192.168.8.252 255.255.255.0
SwitchB(config)#no shutdown
Answer: B
Explanation
To remote access to SwitchB, it must have a management IP address on a VLAN on that switch. Traditionally, we often use VLAN 1 as the management VLAN (but in fact it is not secure).
In the exhibit, we can recognize that the Management Workstation is in a different subnet from the SwitchB. For intersubnetwork communication to occur, you must configure at least one default gateway. This default gateway is used to forward traffic originating from the switch only, not to forward traffic sent by devices connected to the switch.
Question 3
A switch is configured with all ports assigned to vlan 2 with full duplex FastEthernet to segment existing departmental traffic. What is the effect of adding switch ports to a new VLAN on the switch?
A. More collision domains will be created.
B. IP address utilization will be more efficient.
C. More bandwidth will be required than was needed previously.
D. An additional broadcast domain will be created.
Answer: D
Question 4
Refer to the exhibit. The two connected ports on the switch are not turning orange or green. What would be the most effective steps to troubleshoot this physical layer problem? (Choose three)
A. Ensure that the Ethernet encapsulations match on the interconnected router and switch ports.
B. Ensure that cables A and B are straight-through cables.
C. Ensure cable A is plugged into a trunk port.
D. Ensure the switch has power.
E. Reboot all of the devices.
F. Reseat all cables.
Answer: B D F
Explanation
The ports on the switch are not up indicating it is a layer 1 (physical) problem so we should check cable type, power and how they are plugged in.
Question 5
Refer to the exhibit.
What two results would occur if the hub were to be replaced with a switch that is configured with one Ethernet VLAN? (Choose two)
A. The number of collision domains would remain the same.
B. The number of collision domains would decrease.
C. The number of collision domains would increase.
D. The number of broadcast domains would remain the same.
E. The number of broadcast domains would decrease.
F. The number of broadcast domains would increase.
Answer: C D
Question 6
Refer to the exhibit. Give this output for SwitchC, what should the network administrator’s next action be?
A. Check the trunk encapsulation mode for SwitchC’s fa0/1 port.
B. Check the duplex mode for SwitchC’s fa0/1 port.
C. Check the duplex mode for SwitchA’s fa0/2 port.
D. Check the trunk encapsulation mode for SwitchA’s fa0/2 port.
Answer: C
Question 7
Which three statements accurately describe layer 2 Ethernet switches? (choose three)
A. Microsegmentation decreases the number of collisions on the network.
B. If a switch receives a frame for an unknown destination.it uses ARP to resolve the address.
C. Spanning Tree Protocol allows switches to automatically share vlan information.
D. In a properly functioning network with redundant switched paths, each switched segment will contain one root bridge with all its ports in the forwarding state. All other switches in that broadcast domain will have only one root port.
E. Establishing vlans increases the number of broadcast domains.
F. Switches that are configured with vlans make forwarding decisions based on both layer 2 and layer 3 address information.
Answer: A D E
Question 8
Why will a switch never learn a broadcast address?
A. Broadcast frames are never sent to switches.
B. Broadcast addresses use an incorrect format for the switching table.
C. A broadcast address will never be the source address of a frame.
D. Broadcasts only use network layer addressing.
E. A broadcast frame is never forwarded by a switch.
Answer: C
Question 9
Refer to the exhibit:
Which two statements are true of the interfaces on Switch1? (Choose two)
A. Interface FastEthernet0/2 has been disabled.
B. Multiple devices are connected directly to FastEthernet0/1.
C. FastEthernet0/1 is configured as a trunk link.
D. FastEthernet0/1 is connected to a host with multiple network interface cards
E. FastEthernet0/5 has statically assigned MAC addresses.
F. A hub is connected directly to FastEthernet0/5
Answer: C F
Explanation
FastEthernet0/1 can receive traffic from multiple VLANs -> it is configured as a trunk.
There are two MAC addresses learned from FastEthernet0/5 -> a hub is used on this port.
Question 10
The network administrator normally establishes a Telnet session with the switch from host A. The administrator’s attempt to establish a connect via Telnet to the switch from host B fails, but pings from host B to other two hosts are successful. What is the issue for this problem?
A. Host B and the switch need to be in the same subnet.
B. The switch needs an appropriate default gateway assigned.
C. The switch interface connected to the router is down.
D. Host B need to be assigned an IP address in vlan 1.
Answer: B
Explanation
Host A (172.19.1.1) and the management IP address of the Switch (172.19.1.250) are in the same subnet so telnet from host A to the switch can be successful even if a default gateway is not set on host A.
But host B (172.19.32.2) and the management IP address of the Switch (172.19.1.250) are not in the same subnet so host B needs a default gateway to telnet to the switch. The default gateway on host B should be 172.19.32.254.
Hi all, need advice.
born in London, living in Milan for 10 years as a Cisco Network Engineer (Certified CCNP/CCDP) No jobs here.
Looking to go to Dubai.
Any heads up on websites or contacts there etc etc…
Any help will be highly appreciated
Since Host B can cummunication with other hosts in different subnets the default gateway, and the router are operating and configured correctly. so B and C are not correct.
On access interfaces to be possible to telnet the Switch the connected host have to be in the same subnet and in the same vlan of Switch’s management domain. So A is wrong D is Correct.
one point here to notice if you want to telnet the switch from a host in different subnet and different vlan, the host have to be on a trunk interface.

Question 6 in today’s exam
Almost all questions from 9tut
Thanks everyone :)
Hi there everyone, I am planning to take CCNA exam next month, but i don’t know how to start and what best materials should I study/review to sure pass the exam. Can someone send me latest dumps as what I’m seeing in here. I highly appreciate and many thanks to all. My e-mail is “caipols@yahoo.com”
Question 10:
This is tricky…. I built this scenario exactly as is on the diagram.
When connecting to any non-management VLAN, I was still able telnet and ssh to the switch without having to change the default-gateway on the switch.
The router did not have any dynamic or static routing statements as they are directly connected networks.
I removed the default gateway from the switch that was assigned to VLAN 1 and was still able to SSH and Telnet to the switch on the non-management VLANS.
It seems that all the option for Q10 are incorrect. The only real possibility might be option D, if the link between the router and switch were down, vlan 32 could not telnet to the switch via vlan 1.
Anyway
Q 10
I don’t see how the host C can communicate with any other device. It has a wrong IP addr.
(Is not the question but may be is just a little bug )
im confuse how they got the answer for question 10? can u answer again please???
Ping was successful form host B to other hosts because of intervlan routing configured on router.
But to manage switch via telnet the VLAN32 on the switch needs to be configured interface vlan32
along with ip address and its appropriate default-gateway address.
Since VLAN1 interface is already configure on switch Host A was able to telnet switch.

hi.. im scheldule the xams in next month….so can anyone give e tips for preparing..
me daily working with dumps and simulation and also reading todd lamme book’s..
but still lck of confidence..as d amt of xms is huge for me..
hi morik..
what were the simulation in xms..and does it was tough..or tricky??..
Hi guys please any of you send me the dump files my id is :sksnews33@gmail.com
Plz can anyone explain question no 8 ans
Question 8 Explanation :
Switches learn only the source mac address of a Frame sent through their interfaces , whereas broadcast address can not be a source address as it is always a destination address…
Switches only put source MAC addresses into their switching table : they want to know from which direction a frame came from, so they can send frame back in that direction as required. The broadcast address is never the source address, so switches will never put the broadcast MAC address into their switching tables.
Q9 is a bit confusing to me. any explanation would appreciate.
Q9:
How is option D not one of the correct answers?
I see multiple MACs from int f0/1, indicating that it is connected to a device that has multiple NICs….
Additionally, option C (one of the correct options according to the provided answers) states that F0/1 is a trunk link…. interesting….
Do we not use trunk links to interconnect two switches?
Option F seems a little hard to determine… what If I hub that has more than 2 ports? Are we choosing option F due to the consecutive MACs? Any switch I have configured has consecutive MACs.
Also, CDP is another issue here. Whatever device connected to F0/5 may not have CDP running and CDP may not be enabled on F0/5 specifically…
I think options C and D are the best answers.
Option F is also a correct, but more difficult to determine based off of the MACs
Q9: Explanation
A. Interface FastEthernet0/2 has been disabled.
- This is not true, because Switch3 is connected via fa0/2 which appears under local Intrfce under the Show CDP Neighbors commend. If fa0/2 was disabled, switch3 wouldn’t appear.
B. Multiple devices are connected directly to FastEthernet0/1.
- This is not true, because ONLY Switch2 is DIRECTLY connected to fa0/1. you know this by looking at local Intrfce under the Show CDP Neighbors command
C. FastEthernet0/1 is configured as a trunk link.
- This is true. By looking under Sow CDP Neighbors we know that fa0/1 is connected to Switch2, which means we have a link between two switches. Plus, in mac address table we see that you can reach different mac-addresses on different Vlans through fa0/1, which means it is configured as a trunk.
D. FastEthernet0/1 is connected to a host with multiple network interface cards
-This is False, as mentioned in B, switch2 is connected to fa0/1
E. FastEthernet0/5 has statically assigned MAC addresses.
- This is False, you know this by looking at the “address type” of fa0/5 in the mac-address table. it should say either static or dynamic, in our case it is dynamic. which means that the mac-addresses were learnt dynamically.
F. A hub is connected directly to FastEthernet0/5
- This is True, because you can see two different mac-addresses for interface fa0/5 in the mac-address table but under the show cdp neighbors you wont find a switch connected to fa0/5.
I hope this has cleared some confusion, I still didnt write my exam, but I will next week. wish me luck.
Q5 please explain the answer,
only routers can spread collision domain,do not get why collision domain will increased on answer C
Hi Guys got my exam scheduled for next month please send latest dump for ICND2 – mikeytronix.mm@gmail.com
can any one explain me Question 2 ?
SwitchB(config)#ip default-gateway 192.168.8.254
SwitchB(config)#interface vlan 1
SwitchB(config)#ip address 192.168.8.252 255.255.255.0
SwitchB(config)#no shutdown
……….because the degault gateway is 192.168.8.254 but my question is for vlan1 how he has given lower ip add than d default gatway address
wamidh: each port on a switch creates its own collision domain.
anup: as long as they’re in the same subnet it doesn’t matter. some assign the router ports the first usable address, some use the last. you’re just used to it being the first.
Option B is the correct answer of question number 10.
Explanation: It is given in the question that all the hosts are able to communicate with each other so it means that default gateway is configured properly on each host.
Default GW for Host A: 172.19.1.254
Default GW for Host B: 172.19.32.254
Default GW for Host C: 172.19.33.254
Now when someone tries to telnet the switch from Host B, Host B will send the packet to its default gateway as the destination IP is from other subnet. So the packet goes to Router which know where the destination address is and forwards the packet to the switch correctly. But when switch tries to reply to this packet, it does not know where to send it as destination IP is from other subnet and no Default GW is defined on the switch.
Solution: Define default gateway on switch as 172.19.1.254.
The explanation of the q10 is wrong. In the 2nd paragraph, the switch need a default gateway of 172.19.1.254 just like the host A with default gateway 172.19.1.254. It has nothing to do with host B.

Q1 -2 – 9 10 in my exam yesterday
Question 9 – 10 were in the exam recently
Q10 explanation seems incorrect “The default gateway on host B should be 172.19.32.254.” because B can already ping other hosts; so why does it need that default gateway? It seems the switch needs that default gateway. Can someone explain pls?
i need command for these can any body help me i am so worry about it
You are working with a router connected to your network. You would like to gather information about the devices connected to this router. Use the necessary commands to answer the following questions: Which device is connected to the Memphis FastEthernet0/1 interface? Which device is connected to the Memphis Serial0/0/1 interface? What is the IP address of the device connected to the Memphis Serial0/0/0 interface? What is the IP address of the device connected to the Memphis FastEthernet0/0 interface? Which remote port connects Branch3 to the Memphis router? Which remote port connects Miami to the Memphis router? Which platform is running on the device connected to the S0/0/2 interface?

how is the explanation for question 10? which needs the default gateway the host b or the switch?
Any kind souls willing to send me the latest CCNA dump?
Email me at blursotong11@yahoo.com
Thanks ppl..
Concerning Q10:
B is absolutely correct. After trying this scenario, I was able to telnet on the switch from host B and thanks to the (config)#ip default gateway 172.19.1.254 command on the switch.
Q10
How can host B ping without a default gateway, it is still on a different subnet as the other hosts?
