Hi all ¡¡¡
In this hot spot you need to put the show commands or its not necesary?
The 2 hotspot questions are for the ccna exam?

Best regards.

HDLC does not support authentication –> It is not required for a connection to the Dubai Router from the MidEast. The VTY password is for telnetting.

Please explain the answer of Hotspot Routing Question 3. Why C could be the correct answer ? it should be D only.
Thanks!
Kapil Kumar

Which connection uses the default encapsulation for serial interfaces on Cisco routers?

Well Serial 1/1 the default encapsulation ‘For Serial Inerfaces’ is just that. No config. It must be a leased line with 2 IP’s each end.

Where as Serial 1/0 has got a configured encapsulation of Frame Relay presumably as no PPP is configured it is also running HDLC default.

So the question is almost a trick in that they want to know what is the default for ‘Serial interfaces’ not the default encapsulation for Frame Relay.

Hope that makes sense !

Can some tell me if i have to memorize the command or is tab working to complete the command?

Thanx for great info :)

Hi Guys , I am doing CCNA exam in next 2 week , can someone help send me the last dumps to cn8.mdy@gmail.com

Thank ,
be happy in yours life

Hi , I am doing CCNA exam in next 2 week , can someone help send me the last dumps to teseymur@azercell.com,please
Thank ,

for q1, why is the answer not d? Doesnt the router do this for a broadcast?
Or am I wrong

who has a definative answer for q3?

I think the question for Q1 should be, “if the router R1 receives a packet…” using “has” instead of “receives” adds confusion to the question.

the answer is B, since the router does not forward broadcasts.

Q3- answer is 3, the switch does not change the frame, it only reads the destination address and forwards itto the specific port that has the mac address.

Thanks a lot for providing info on this sim. I passed today with 841 thanks to this page.

could someone please, kindly send me latest ccna dumps as i will be writing the exams next week friday unslush2008@yahoo.com

@shannon ur Q1- the router do not forward broadcast, so that is why it drops it but if it were a switch it thus forward broadcast.

All can be

The Frame-Relay SIM was on the 640-816 exam today. Just to let others aware who are taking the exam soon, there is a typo on one of the questions.

What destination Layer 2 address will be used in the frame header containing a packet for host 172.30.4.4? <—- 172.30.4.4 should be 172.30.0.4; answer still remains the same by using the "show frame-relay map" command on the main router.

can you telnet :
NORTE
S-AMER
EURASIA
SEA

????????

because as i see some of the questions needs a look in the config of these routers since this is a multi-point topology…..

I really respect what you’re posting here. Keep posting that way. Take care!

I shall be thankful to that person who shall provide me latest dump of 640-802 email on kashiflf@hotmail.com, thanks in advance

Can someone please email me the latest CCNA dumps. I will be taking the exam in 2 weeks.

I give my thank in advance for whomever is willing to help.

@shannon

Routers dont forward broadcast so the answer is wrong

I need Help from all of you guys, Please could you tell me which one the correct answer for Question number 4 http://www.9tut.com/ccna-hotspot-questions {hotspot frame-relay QUESTION}.
I ask anyone took the test, what their answer ? , and why ? If no password is required
Please help me and thank for all of you.

hello all,could some one help Qn.5.why the correct answer is A not D?
also i need latest ccna dumps deaparately one one who can help out there?:mkisochi@yahoo.com

Thank you! 9 Tut! ;D

@JM host A across two router
So A is correct

A few thoughts :
1)for question 3 of hotspot routing question…the answer should be 3 ..that is the packet gets encapsulated 3 times…
2) also i came across a frame relay question in which it asks “what password should be configured on Deepsouth router to allow a connection with MidEast router???? how to do tht???…we cant access Deepsouth or the Mideast router …so is there any info on Dubai router tht will help answer such a question????????

3) Also i want to know for hotspot routing, Q1, why isnt D correct..a router fwds broadcasts….otherwise whats the use of Broadcast address ??..isnt it used for sending out packets to all hosts in a given network???…then y is the answer B: ie not a valid ip address?????

Hoping to get some feedback !!..on all my thoughts …possibly…:)

Host A -> Router 1 s0/0 -> S0/1 Router 2 s0/0 -> S0/0 Router 3

B. 252
C. 255
D. 254

Answer: A

Any idea why the answer is A?

please define it brief…….

@arunesh:

TTL value= 255- no. of hops(routers passed)

here the packet passes over 2 routers..as per the path u have mentioned…(ie router 1 and router 2)..remember, the packet didnt cross or pass router 3..its destination was the interface S0/0 of router 3. so it passes router 1 and router 2 …ie 2 routers…so

TTL value= 255-2= 253 is the TTl value…hope this helps..!!

@Deepti

Not sure about your 2nd thought, but for your 3rd thought – routers define broadcast domains but do not forward broadcasts, switches will forward broadcasts, that is why you can have multiple switches in a broadcast domain.

@ deepti
HDLC is configured on the s1/1 interface which one corresponds to the MidEast and it is the default encapsulation for serial interfaces and it doesn’t requiere any authentication because of that I think that there in no need for a password.
I am thinking to take the exam on August 26th, but I am a little worried about Security Teslet.

@9tut
please review question 3. i believe the answer should be D.

@9tut
Hotspot Frame-relay Q4

you already gave an output of *show running-config*, the password for telnet is *Tlnet*
please fix option D
D – Tlnet
and set D as the answer for this question

Could you please provide latest hot spot questions?

for question 3 :When a packet is sent from Host1 to Server1,in how many different frames will the packet be encapsulated as it is sent across the internetwork?…

what’s the answer…if any1 is damn sure pls let me know…i have an exam tomorrow..

@deepti
host –> default gateway (1)
R1 –> R2 (2)
R2 –> server (3)

i’m counting 3 frames.

yeah to me it seems 3 too..but a lot of ppl claim its 2…i dont know depending on what is the answer 2?..something to do with encapsulation?…whatever it is ..i feel tht basically the packet undergoes framing 3 times as its sent frm host 1 to server 1…any thots ??

Hotspot Routing Question

Q4:

I understand that answer should be router R2,configure a default static route to the 192.168.1.0 network, because if internet users want to see private users, NAT 1-1 should be configured.
Is C answer incorrect ?

@ Deepti and Xallax. I am not pretty sure but I think that are two frames. This is my suggestion when the frame arrives to the serial link it doesn’t matter the MAC address, because it is a point to point connection because of that I don’t count this step as a frame encapsulation. The frames are in the Ethernet interfaces where the router creates a new data-link frame with its interface’s MAC address as the source and the destination MAC is the Server’s MAC address. If I am wrong plz let me know.
I am gonna take the exam this friday. I am very nervous.
THX

@nerroazurro
data goes through encapsulation and decapsulation as it passes along the network.
you agree that all these devices (pc, R1, R2, server) operate at both layer1 and layer2. there is no doubt about it.

* PC has that to send, builds a segment with source/destination ports and sets the transport layer protocol of choice (TCP or UDP), builds a packet with source/destination IPs, gets the packet into a frame with source/destination MAC addresses, transforms the frame in bits, sends data to R1

* R1 gets the bits, converts them to a frame, reads the destination MAC of the frame, decapsulates the frame, reads the source and destination of the packet, checks the routing table, sends the packet to the appropriate exit interface, encapsulates the packet in a frame with new source/destination MACs, converts the frame to bits, sends the bits to R2

* R2 receives the bits, checks the MAC, decapsulates the packet, checks the destination IP, sends the packet to the right exit interface, builds the frame with new source/destination, converts the frame to bits, sends it to the server.

* the server gets the bits, builds frame, checks destination MAC, decapsulates the frame, checks the IPs, decapsulates the segment, checks the source/destination ports, decapsulates the data.

how many frames?
1: PC – R1
2: R1 – R2
3: R2 – server

wrote it without checking it…
there are no MACs on serial links, my bad. everything else stays

Q4: Hotspot Routing Question

I understand that answer should be; “router R2,configure a default static route to the 192.168.1.0 network”, because if internet users want to see private users, NAT 1-1 should be configured on R2

Is C answer incorrect ?

Q.3 Answer is 3

Explanation:

First: Host1 encapsulates the packet into frames and forwards to the switch.
Switch in turn forwards the same frame to router R1.

Second: Router R1 receives the frame on one interface and it is encapsulates into new packet once it leaves the router R1 towards the direction of server1.

Third: R2 receives this packet and it also encapsulates the frame into new packet when it is forwarded to server1 on different interface of R2.

Therefore the packet is sent using three different frames to reach from Host1 to server1.

When a packet is sent from Host 1 to Server 1, in how many different frames will the packet be encapsulated as it is sent across the internetwork?
A – 0
B – 1
C – 2
D – 3
E – 4

Answer: D – 3

https://learningnetwork.cisco.com/message/69455

got a small doubt with question3…??

host 1 sends frame to switch;
switch encapsulates the frame into segments (host/dest mac addresses) & 4wards 2 Router1;
router1 encapsulates the frame into packets (host/dest ip addresses);
now what will router2 do..??

i am just a beginner, no intentions to confuse or spread wrong info, apologies.. kindly help..!!

rohit;)

@rohit4rmgoa
the switch does not encapsulate anything, it just reads and forwards.
layer keyword:

L1: bits
L2: frame
L3: packet
L4: segment

you have used the keyword “segment” when referring to a L2 operation made by the switch. that is incorrect.

host1 sends to router1
router1 sends to router2
router2 sends to server1

thank you for asking, hope this helps

Hi, Appreciate if someone could send me the latest dumps at treepanel.ken@hotmail.com , i plan to take the exams at the end of sep.
Thanks.

Guys, this is really helpful as i’m preparing to take the exams also by sept. ending,latest dumps is highly appreciated,ibukun_nelson78@yahoo.in

hi,

so is the answer to question three, 2 or 3 ?

thanks

just took the cisco 640-802 exam friday, did not pass with score 762. found this site looks like very good and similar questions and sims to the exam. i am believing from reviewing this site if i study the questions/answers and do the sims i can pass. also if anybody has any useful info for preparing i am traitt@yahoo.com

thanks

Hi Guys , I am doing CCNA exam in next 1 week , can someone help send me the last dumps to saad.otp@gmail.com
Thank ,

hello, i also will be taking the CCNA in a couple weeks or so (retake) if anybody can also send last dumps to traitt@yahoo.com thanks.

Router1>show version
System image file is “tftp://172.16.1.129/hampton/nitro/c7200-j-mz”

A. Router 1 has specific boot system command that instruct it to load IOS from TFTP server.
B. Router 1 is acting as a TFTP server for other routers.
C. Router 1 cannot locate a valid IOS image in flash memory.
D. Router 1 defaulted to ROMMOM mode and loaded the IOS image from a TFTP server.
E. Cisco routers will first attemp to load a image from TFTP for management purposes.

What are the best two answers? I think A and E. But i saw someone answered A and C.

Q3 The answer is C because the question asks how many different frame (types) of encapsulation.
1st type as it leaves the host to the switch before it hits the router
2nd as it goes across the serial link
then back to the first type as it then goes into the router and across the lan to the server.
While there are 3 occasions of encapsulation, there are only 2 types.

Great site and a great help

@Justin: By default Cisco router looks valid IOS image in:
Step 1: in flash mem. if it no image in flash go to step 2
Step 2: looks image on TFTP server if no image go to step 3
Step 3: boot in ROMMON mode

So correct answers are: A (specific boot instruction in config) and C (step 2 in default booting sequence).

hello, i also will be taking the CCNA by next week wednesday pls can you send the latest dump too segunfemmy@yahoo.com. thanks

Hi, can any one send me dumps for ccna exam to rmehar_sk@yahoo.com…i am taking next weekend…….any suggations for preperation???????

Q2 why is the answer is A and not B? 9tut or anyone please explain.. thanks

@xallax

which network protocol does DNS use?(choose one)
FTP,TFTP,TCP,UDP,SCP

i am really confused because DNS uses both UDP and TCP (port 53).which is correct?.the dumps say UDP

@ayaj
so…
udp is used when the request/reply have small amounts of data.
looking at your questions… it asks which NETWORK protocol is used. that’s stupid. ftp/tftp are applications, tcp/udp are transport layer protocols. what is scp?

“DNS primarily uses User Datagram Protocol (UDP) on port number 53 to serve requests.[5] DNS queries consist of a single UDP request from the client followed by a single UDP reply from the server. The Transmission Control Protocol (TCP) is used when the response data size exceeds 512 bytes, or for tasks such as zone transfers. Some operating systems, such as HP-UX, are known to have resolver implementations that use TCP for all queries, even when UDP would suffice.”
http://en.wikipedia.org/wiki/Domain_Name_System

Qusetion 4 is not clear…can any one describe what is the best answer A or D ..what is the diffrence between c0nsole & console…. enable & en8ble..what is T1net….

@mg
that’s just the text of the password

ccna exam in question where the What destination Layer 2 address will be used in the frame header containing a packet for host 172.30.0.4?
is supposed to do the assignments the command is (Show frame-relay map), but I make this command is not correct, and even when I put (show running-config) do not see the layer 2 protocol for each interface, and with (show interface) all appear with the HDLC protocol.

Why?

CCNA HERE I COME…

Q#4 What must be configured on the network in order for users on the Internet to view web pages located on Web Server 2?

A – On router R2,configure a default static route to the 192.168.1.0 network
B – On router r2, configure DNS to resolve the URL assigned to Web Server 2 to the 192.168.1.10 address
C – On router R1, configure NAT to translate an address on the 209.165.100.0/24 network to 192.168.1.10
D – On router R1, configure DHCP to assign a registered IP address on the 209.165.100.0/24 network to Web Server 2

Ans:C

What is the purpose of using the NAT on incoming packets or traffic???Can any one explain??

@cisco: Web server 2 has private IP address. But we cannot to use Private IP in the public network so we need some method to camouflage private IP. This method is NAT.

@Dims:thanks dude i’ve not abserved that??

9tut plz add a NAT and NAT overload(PAt)questions and tutorials

@Cicso craze

Foremst reason is privacy and security.
Secondly, public ip are not allowed in private ip areas.

Just like in certain high class society, one has to go through a check point before allowing an entrance. The “check point” is like “NAT”.
Public……check point(NAT)…….Private.

Excuse me for being so graphical.

@xallax

Please, can you kindly give a breakdown on these two commands for me.
“ip route” and “default route” Where and when are they applicable. Thanks.

@anonymous
ip route – manually create a route towards a network. will have an administrative distance of 1 by default – can be any network
“default route” – default network – 0.0.0.0 0.0.0.0 – default place to send packets if the destination network is unknown to the router

Q2 above.

Users on the 192.168.1.0/24 network must access files located on the Server 1. What route could be configured on router R1 for file requests to reach the server?

The answer to this is : ip route 0.0.0.0 0.0.0.0 s0/0/0 according to your explanation shouldn’t it be: default route 0.0.0.0 0.0.0.0 s0/0/0 (Does these two commands basically do the same thing)

Is kinda confusing. Can you give a breakdown. Thanks.

@Anonymous

There is no command on the global conf mode that is “RouterC(config)#default route ?
% Unrecognized command ……” maybe i have a different ios version.

There is such a command as “RouterC(config)#ip route ?” and also “RouterC(config)#ip default-network ?”

so may be its a trick question to see if you know your routing commands

The question above titled “Hotspot Frame-relay Question” was on the ICND2 exam today.

Obviously this has to be en PPP encapsulation, if asked for a posible password for SOUTH_ROUTER you pick c0nsol3, and for NORTH_ROUTER you pick t31net. If you’re running HDLC, i would pick “no password is required”.

then what we choose if its c0nsol3 we choose E-Console .. bcz e replaces with 3 .. what we choose ??

Hi guys i m giving CCNA exm in 2 weeks. can any1 forward me dumps to jarjishussain@yahoo.com

thanks

Hot Spot Routing Question 1: 192.168.1.255 is a “directed broadcast ” address. For mask /24 means that router will check and match the first three octets in the routing table and route packet to network 192.168.1.0 /24 . Then in layer 2, it will change it to “local broadcast” which is FF-FF-FF-FF-FF-FF to broadcast in the local broadcast domain. I think the better answer should be “D”.

If the packet address is 255.255.255.255, then router will drop it.

Hello everyone,
Can anyone kindly send me the latest dumps for CCNA640-802
This would surely be a great favour.
Thanks in advance.

I agree with this statement…. Any one else have thoughts on this….

Please…do SIM come during the normal questions or at the end of the normal question or it is a different question on its own….someone pls help me,I am writing my exam tomorrow…thanks

@ cisco student, from my own point of view,the router won’t forward the packet with destination of 192.168.1.255. The router knows its network and understands definately that,that’s a broadcast address for that segment.since it as a mask of /24. NB: routers don’t forward broadcast by default…..

@3o3o: Sims are independent questions. They appear randomly in the exam (so you may see it at the beginning, in the middle or at the end of your exam).

Hi All,
my humble contribution to answer the Hotspot – routing Directed Broadcast Question mistery
(not CCNA, but I will try it on the Oct 29th)

from the net:
http://www.certforums.co.uk/forums/general-cisco-certifications/16819-ip-directed-broadcast.html

….”directed-broadcasts are generally a bad thing, and are disabled by default on all interfaces in Cisco IOS.

A directed-broadcast is an ip packet with a destination address that is a valid broadcast address for a subnet, ….but does not originate from that subnet.

It is trivial to abuse directed-broadcasts for smurf or fraggle attacks and so directed-broadcasts should always be disabled (the default) unless there is a need for them. In a properly designed network I can’t think of a need for directed-broadcasts. If you needed to use them, an acl can be configured to limit malicious use of directed-broadcasts.

An example of a directed-broadcast would be a packet sent to a router interface e1 addressed to the broadcast address of the subnet on interface e2. The router will then helpfully direct the packet out e2 and “explode” the broadcast on the subnet. It is easy to see how an attacker could exploit this, hence no ip directed-broadcast is the default.”

….

and in addition:

ip directed broadcast
According to cisco press 642-812:

“the no ip directed-broadcast command configures the router or switch to prevent the translation of a directed broadcast to a physical broadcast”.

Conclusion:

Correct answer is B – because
1. packet has originated from the same LAN. If it was from another LAN on the same Router it would be translated to al “Fs” Layer 2 broadcast,

2. the option that packet has arrived from the Internet is not valid because of the NAT.

This eliminates all options and just B stays valid – I would say.

Thanks 9tut

Hotspot – routing,

The answer on Q3 – how many times frame header is gonna be changed is 3.

Or, that is “what cisco guys would rather like to hear” here; and, as per cisco academy curriculum…in addition, all Layer 2 encapsulation is frame – like one, and defined by Data link layer protocols.

thanks

Reply to Hot Spot Routing Question 1:

Correct answer cannot be B

B – R1 will drop this packet because it is not a valid IP address

It is because 192.168.1.255 /24 is a directed broadcast address and it is a ” valid ” IP address. As far as the routing goes, if the route existed in R1 routing table, R1 will check the destination address and compare to subnet mask for longest match. In other words, router use network addresses for routing, host portion is not important until the PDU pushed down to Layer 2, then host address must be able to translate to mac address.

/24 = 255.255.255.0 means that the first 24 bits must matched, and the last 8 bits, it doesn’t matter, and any last 8 bit values will change to zeros in route determination. (hardware-wise: host portion logic ANDed with Zero portion of mask, the result is always zero)

So for the destination address is 192.168.1.1 or 192.168.1.100, or 192.168.1.255, R1 will ignore the host portion and change the address to the network address 192.168.1.0 and forward the packet to the destination network which is fa0/0 interface according to the routing table.

For switch SW-A, the host address 192.168.1.255, will translate to local broadcast destination mac address FF-FF-FF-FF-FF-FF to flood all ports except the port where the frame came from.

Yes, It would be translated to FFs but only if it came from another LAN on the same router(by definition of directed broadcast);
but there is not another LAN as they said “small network”, and Routers do discard broadcast, which is the one of their main functionality. Nor routing protocol is needed or configured (single LAN).

Another network attached, is the WAN, and NAT” is” implemented what we know from the next question.

This is a typical Cisco Academy question, tricky and unpleasant.

Hello,

I tried to set up a Packet Tracer for the LAN part. There is no ip directed broadcast in Router R1. I ping 192.168.1.255 in Router R1 CLI, Router R1 send out echo requests to all hosts and all hosts reply. It seems the Router R1 didn’t drop the directed broadcast packet. The following is from the PT R1 CLI output after PING.

R1#ping 192.168.1.255

Type escape sequence to abort.

@Packet Tracer:

An IP directed broadcast is an IP packet whose destination address is a valid broadcast address for some IP subnet, but which originates from a node that is not itself part of that destination subnet. (from cisco.com)

I think in your case router R1 has interface in the same subnet.

Try to ping from a host in the another subnet.

@olo

default router always work in a stub networks e.g router towards internet. Default route it actually routes you to the network that is not listed in your ROUTING TABLE… Example
R1(config)#ip route 0.0.0.0 0.0.0.0 192.168.1.2 or 0.0.0.0 this means please route me t oany 0.0.0.0 => network 0.0.0.0 => to any subnetmask with an administrative distance ( interface of the router or ad )to get to that netwok is 192.168.1.2…. but in this case since R1 is the stub router you can place the admin distance to its interface (s0/0) eg. ip route 0.0.0.0 0.0.0.0 s0/0.. Hope that helps….. :)

Routing Q1. Answer is B, as stated…Why?

P.185 of Exploration Network Fundamentals says this…

‘Although routers do not forward directed broadcasts by default, they can be configured to do so.’

Also Q3. Answer is D. 3 different frames form Host1 to Server1 as explained by xallax. There’s 2 different ‘frame types’, but question asks how many different frames, not frame types.

Great site by the way!!

i m not able to understand Q3 can anybody explain?

@vikas
1 frame from Host 1 to R1
1 frame from R1 to R2
1 frame from R2 to Server 1

i’m counting 3 frames.

@ Xallax
i’m countin’ 2 frames only !!

the Q said different frames got that .
