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.
Passed Marks: 975, 99.8% from 9tut no need to exert effort for latest dumps. Labs EIGRP, ACL Sim 1 & 2, practice all modifications coz it was given on random. 9tut is enough to pass the exam. GoodLuck. .
Mike – I agree, I fail to see how this could work. Host B cannot ping Hosts A and C without a default gateway. If there are no access lists in place, or any settings on the vty lines restricting telnet traffic, then being able to ping Host A (and B) should mean telnet access to the switch is also successful.
Dear admin;
In Q2 solution, among the choices, Should it be like this?
SwitchB(config)#ip default-gateway 192.168.8.254
SwitchB(config)#interface vlan 1
SwitchB(config-if)#ip address 192.168.8.252 255.255.255.0
SwitchB(config-if)#no shutdown
vlan instead of if.
Q 10 my point for ping is it broadcast for the address it doesn’t have to all interfaces except fa 0/2 through which it came. But telnet it wont.

thanks 9tut
Suman is right for Q2.
Mike c is right for Q10- I agree with Mike c.
Suman is right for Q2. cmon is more perfect on Q2
Question #2, what is the different between answer B and C ? anyone please help ?
@SAM
Q2, B= first define gateway then go to VLAN interface and assign IP
Q2, C= after entring VLAN interface, you cant define gateway
Q10 – Host B is a member of vlan 32 – it has a default gateway configured (fa0/32). It goes out of this subinterface and is routed to the other vlans on the router. The management interface (vlan1) on the switch does not have a DG configured so it will not reach the router and other vlan subnets like the one host B is a member of. Host A can reach the switch because they are on the same subnet (vlan1)
@ Sam :
difference b/w B & C is that : ip default-gateway never uses subnet mask,but subnet mask must be entered for confirugring vlan alongwith ip address.
i-e
switch(config)#ip default-gateway a.b.c.d
switch(config)#int vlan 1
switch(config-if)#ip address a.b.c.e 1.2.3.4
OR
switch(config)#int vlan 1
switch(config-if)#ip address a.b.c.e 1.2.3.4
switch(config)#ip default-gateway a.b.c.d
@ Mirza :
there is no sequence ,you may enter the commands in any order as you wish.
Hope this is informative for you.
switch(config-if)#no shut
switch#copy run start
A/M commands should be entered to move the vlan to ”UP” state and for solid marks in actual exam.
You can ping any host without a default gateway, you just won’t be able to telnet to the switch
That is for Q10
has anyone heard about changing the exam next month???Is that true??please tell me because I intend to take the exam next week…
Where have you got that information? I’ve scheduled my test in next wee too :(
Can someone explain Q9 please
I also have my exam next week and its a repeat, is it really changing? in what way, is 9Tut not ok for revising then?
for shivers Q9
the two MAC addresses learned from FastEthernet0/5 belong to two hosts attached to the hub that is attached to the port f 0/5 of the switch .
proof is: the same id vlan (vlan 2) for both mac @
@ mac both are in the same vlan distiner because they are send to the same port that is f 0/5
and which represents the vlan 2
Port 0/5 f = vlan 2
can someone pls explain to me question 3 and 5!!!!
Thanks zaifi and Mirza for an explanation. A subnet mask is a big deal on default network command.
Q#2, answer B and C, why they don’t change to interface mode? they are still on global configuration mode. Is Cisco having a mistake or Cisco did like this in purpose?

Q1, 4 and 6 were in exam
Dear all,
Can anyone help me about Q7 , why B. If a switch receives a frame for an unknown destination.it uses ARP to resolve the address. is not the answer.
thanks
@Stray- Arp is layer 3 protocol used mostly on routers. B is not a correct answer.

ramos1987… Plz send me the dump to sureshkcmc@gmail.com
In question 10 …. The vlan 32 needs to be assigned with the ip the address of same subnet of host B.. thats how telnet should work…
Question 10 is correct.
The pings work because the router is configured with the appropriate subinterfaces, but because the management vlan is on a different subnet than host B, so it does require the proper default gateway to be assigned to the switch. This is the same concept that we see in question 2, except the topology is different. The management default gateway would also need to be in the same subnet as vlan32, so host B does not need to make any changes.

thanks for ur help
Question #5, #10 on my exam last Sunday, 2014/10/5.
Thanks a lot 9tut. Almost all questions were from here except for two.
Had the EIGRP and ACL 1 sims.
what is the major modification or added Lab Sim in the exam?
please 9tut explain
of course i see changes in Labs such as OSPF, EIGRP
I still don’t understand on question #9. How did you know that interface fa 0/5 is directly connected to a Hub?
Some one explain please.
On the explanation it said that because there are multiple address learn from this link. but it doesn’t explain how. because fa0/1 are also learn multiple address too. wouldn’t that make them a direct connection with a hub too?
9Tut explain please
Can someone please send me the latest dump? I take this exam next week!
acordero2@me.com
Question 10
right right choice but wrong Explanation
SWITCH need to configurd with defulat-gatway , not host B
Bee for question 9, I believe fast0/5 is connected to a hub because the MAC addresses are all from VLAN 2. Fast0/1 is a trunk link since the MAC addresses are from different VLANs.
regarding question 9, interface fa 0/5 has 2 MACs which means that it is connected to a device that then is connected to 2 others, the only devices that can do that are HUBs, bridges, switches, and routers, since in the show CDP neighbors output there is no switch, bridge, or router connected to that then the only explanation is that either the cable is divided into 2 cables or a hub is connected since it doesn’t respond

Q 10
for accessing the Switch , you should be in same subnet.
Host B is not in same subnet as well as not belong to same Vlan.
