Answer to question 10 should be “D” as switch management IP address is in VLAN 1 we can confirm that from the router subinterface. Once you put address in Vlan 1 and change the port from VLAN 32 to 1 purpose will be solved.

Q10: the host B can make telnet to the SW If we assign a gateway to the SW that gateway is the same of vlan1 gateway…and host A from vlan1 like SW Because of that he can telnet the SW.

Q6 : I’m a little bit surprised : CRC errors are mainly due to damaged or too short or noise polluted cable.

Collisions and late collisions seem to me more a proof of duplex mismatch than CRC errors.

Q2 answer C is confusing…. output should be in int config mode after ‘int vlan 1′ command…. one of the reasons it is wrong, but output doesn’t go to ‘int config mode’ in the right answer B either, so…. problem is where ‘ip default-gateway’ is configured, and it should be in global config mode…. B is right answer, i ran it in PT…..

Hi Mahi ,,

In Q9, We can see from the given information that port Fa0/1 is dealing with multiple VLANs. A port can only allow multiple VLANS to pass through it if it is a Trunk port only. So option ‘C’ that Fa0/1 is a trunk port.

Similarly from the given data we can see that the port Fa0/5 is serving two MAC addresses on same VLAN, which is only possible if we connect that port to a HUB and then HUB is connected to multiple devices.

Hi Searche,

In Q6 its been shown in the output that there are errors being received on the link. Errors could be one of the following reasons.

Duplex mismatch on the ports of switches (one using half duplex, other full)
Speed of the ports (one set to 10 Mbps other set to 100 Mbps)

We know that port on switchC is set to Full duplex 100 Mbps. We will check and verify if same values have been set on Switch A port fa0/2 … :)

@keskarashutosh

you don’t need a default-gateway set on the switch for host B to ping host A. There can be no default-gateway set on the switch and host A and host B can still communicate. But in order to telnet the switch from host B, the switch needs to have an ip-address in the management vlan (vlan 1) as well as an ip-default-gateway.

By: Anonymous

Anonymous — Mon, 23 Mar 2015 00:38:00 +0000

oh I see, yes answer is b where you put ip default gateway globally. Ans C is different as it is under vlan 1

B is correct

In Question 10 :- It is mentioned that the “pings from host B to other two hosts are successful” means Host B (172.19.32.2) and Host A (172.19.1.1) can communicate. Already the switch has an appropriate default gateway assigned. Isn’t it?
will anybody plz explain.

@ Tuscler

Please read the “router on a stick” chapter. Basically you will need to:
1. create sub interfaces on the router’s Fa0/0 interface
2. assigned IP addresses to each sub interfaces that are in the same subnet as the hosts (also carries same VLAN)

So, since Host C and Fa0/0.3 are not in the same subnet, ping to switch won’t work either just like in Host B case.

The lab simulations were Eigrp , ACL1 (similar to 9tut exactly) and ACL2 (modification 3 but with host B to access the finance server)

Good luck for everyone, just be relaxed its very very easy :)

By: Quintin

There is an error in Q10. Host C IP address is wrong. It should be 172.19.33.13/24
. So it stays on the same subnet as its vlan gateway 172.19.33.254/24.

By: TaSS

TaSS — Wed, 18 Feb 2015 19:02:03 +0000

I was wrong.

Finally, i understand the question (Q10):

Just think change switch for host: do you need a gateway to access it? It doesn’t care about all other hosts and their gateways.

I hope with this could help others (like me) don’t waste a lot of time with this…..

@Claudio I’m agree with you. If you CAN ping to the others hosts in DIFFERENT VLAN, FROM HOSTB, then routing is working well. I don’t understand why host-b can’t telnet the switch (the vlan is the same for host-a, with host-b can ping without problems)

By: Apur

Apur — Thu, 12 Feb 2015 09:47:31 +0000

@danish

q5.C is correct….. every switch port has its own collision domain unlike hub which is single collision domain device.each port in switch has its own dedicated BW bt hub dont have. so collision domains will increase once hub is replaced by switch.

D is correct coz neither switch or hub can break broadcast domain to do so we need router to break broadcast domain. so weather it is switch or hub broadcast domain will remain same.

Can every one help me with question 1 please?

Based on my knowledge if switch doesn’t know a address it will send ARP to find it … But in Q1 said it will send the data to all the ports except data originated port???

Q10 – Explained as I understand it.
Host B can ping Host A and Host C, so Host B has a default gateway set. (The explanation is incorrect and should say “Switch”, not “Host B” needs a gateway set).
Host A can telnet to the Switch because they are both in the same VLAN (subnet).
In order for Host B to telnet to the Switch, it has to connect to the telnet on the Switch’s VLAN1 management interface. The Switch can communicate to all 3 Hosts at Layer 2 using MAC addresses, but the telnet requests needs to traverse networks. Therefore, in order for the switch to establish the Telnet connection with Host B, a default gateway needs to be set in the Switch so it knows how to respond to the Telnet request to it’s VLAN 1 interface from Host B.

I hope this helps. I do think that answer D would actually work since Host A has the same setup. Can anyone else confirm that?

Q9,
Switch1 has your fas0/1 connected to Switch2 fas0/1. Trunk link here
Switch1 has your fas0/2 connected to switch3 fas0/5.

So the mac addresses ending with: 1540 and 1545 are showing that are connected on port fas0/5 of the switch1, so for two mac address be sharing the same port, its possible only using a hub as said on answer F.
It also should be possible if a pc is using a virtual machine, but it is not the case.

By: Claudio

Adm: Please do a correction in the second part of the Q.10 Explanation, if you agree. It is describing “Host B” IP Forwarding process and that is not an option in the set of Answers first. What must be noted there is SwitchB’s IP forwarding process (Using a Vlan interface working the same as a NIC) , since it has to forward traffic to another IP subnetwork than the local one, in this case in response to a ping originated from “Host B”. Note that “Host B” has already configured a Default Gateway, otherwise this part of the question text: “…but pings from host B to other two hosts are successful.” wouldn’t be possible. In Summary: Everything is correct except you are mixing “Host B” and “Switch B” roles at the second part of the explanation in my opinion. Hope this helps. BR

Q2 would be totally correct in my opinion if since line 3 on, the prompt mark would be (config-if) instead of just (config):

CORRECT:
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

INCORRECT:
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

By: Fyoros

Fyoros — Fri, 02 Jan 2015 16:45:11 +0000

@i’m ccna

- Microsegmentation is the fact to divide a big collision domain into several smaller ones -> the smaller a collision domain is, the fewer collisions occur (considering half duplex, because there are no collisions in full duplex).
- Each STP instance contains 1 root bridge only with all its ports in forwarding state (designated); The other switches of this instance will only have 1 root port.
- Creating Vlans is the ability to create mode broadcast domain : each Vlan has its own subnet (its own broadcast domain).

Hope this helped.
