Thanks
When we can expect some update?
This exam is still valid and everything is from that Dump. All DD are same pattern but MQs are flapped but all same. please take care of Simulations . because this time they were asking some different questions like today one question was TOtal Prefixs that were (45) not labels that Mohammad mentioned 21. policy-map question was under "QoSPolicy" not QoSpolicy1 or QoSpolicy2.
this is still valid I hope?please
Today I passed the exam my score was 976 still is valid
I want to know that DD answer order is same as in dumps or change ?
thanks
Thanks everybody, especially to Mohammed.
1-the updated exam most questions from 79 -130 q in the updated actual test ver right ??

Thanks in advance
thanks Mohammad

The one missing lab -QoS - question from Mohammad --> in this question the sh run commands are working to get the info

and the DD is the same

Follow Mohammad's comments
Good luck
Thanks!
Thanks
follow tips by
Mohammed from United Kingdom
Ali Baba Ibn Dunya from Sweden
In the exam answers are well shuffled. Dont memorize the number, memorize the complete answers and how to identify the answers.for the LAB some answers are wrong .learn the command line how to get the answers.even some command on the dump answers are not valid in the exam.so be careful with the LAB.
Thanks
Please tell me that in exam labs, we just have to enter the "show" commands, and from this show command we will choose for the correct answer? please guide me.thank you
Thanks
Dumps are still valid
72 question
4 DD
2 Labs
Thanks
Passed today an hour back with 978. No changes in DD-78.
the "IIq" policy-map? (Choose 2)
A.Traffic matched by the "cisco1" class-map will be assigned to the priority queue.
B.The "IIq" QoS policy is applied to the gi0/0 interface in the output direction
C.Traffic matched bythe"cisco2" class-map has a maximum bandwidth of 30%
D.Traffic matched by the"cisco3" class-map has no priority and has a minimum bandwidth guarantee of
20%
E.There are no packets being matched by the "class-default" traffic class in the "IIq" policy
Correct Answer: AD
Issue: Issue: show policy-map interface or show policy-map
You will notice that "cisco1" class map is assigned to the priority queue (the command is configured under policy-map IIq class cisco1 priority xxx)
"cisco2" class map: is indeed configured using bandwidth 30%, however that defines the minimum bandwidth but not the maximum.
"cisco3" class map: is indeed configured using "bandwidth 20%", No priority configured and that will define the minimum guaranteed bandwidth.
The last choice is wrong! check under "show policy-map interface" There are 4 or more packets being matched by the "class-default" traffic class in the "IIq" policy.
Class-map: class-default (match-any)
4 packets, 968 bytes
-------------------------------------------------------------
Thanks to Mohammed
Can you please let me know, if the Dump is still valid?
All the questions are from this file but the multi-choice had different order while the D&D questions is exactlly the same. For the Lab questions : Many thanks to you Mohamed for you brillient correction on this forume regarding thoes Labs. I confirm that your answers is all correct
Thanks again for everyone participate with his comments
Thanks to Mohammed
A.Traffic matched bythe"QOS-HTTP-1" class-map is shaped to an average is rate of 2560000 128000bps
B.Traffic matched bythe"QOS1-HTTP-2" class-map will be queued in the low-latency-queue which has a
maximum bandwidth guarantee of 64000
C.Traffic matched by the "QOS-FTP-1" class-map can't use more than 256 Kbps under any condition
D.The "QOS-POLICY is applied to the gi0/0 interface in the input direction
Correct Answer: C
Issue: show policy-map interface or show policy-map
1- QOS-HTTP-1 and QOS-HTTP-2 are not shaped, under each class you will notice bandwidth configured. Only "QOS-FTP-1" class-map has shape average at 256 Kbps. The policy is applied to the g0/0 in output direction.
------------------------------------
1) All questions and d&d are correct. Labs - see Mohammed's answers, they are 100% correct. The correct answer to one lab question he did not mention is "B. The "traffic-policing" QoS policy will police the traffic matched by the "test12" ACL to 3 mbps and will drop all
exceeding traffic" (as in dump +see note below).
2) In lab:
- correct syntax is "show policy-map interface gi0/0" (don't forget "gi0/0").
- where the answer is "B. Traffic matching the "MARKING1" class-map will be marked with MPLS EXP 5" enter two commands: "show policy-map interface gi0/0" and "show class-map".
- where the answer is "B. The "traffic-policing" QoS policy will police the traffic matched by the "test12" ACL to 3 mbps and will drop all exceeding traffic" the only command that work is "show running-config policy-map". Commands "show policy-map" or "show policy-map traffic-policing" do NOT work.
- correct syntax is: "show mpls ldp discovery detail", NOT "details" (as was posted earlier).
- to scroll output use spacebar.
- "conf t" and "enable" are not needed.
3) All answers shuffled (except for D&D), not only multi-choice.
4) Drug&Drop with option "Provide a strict priority queue to allow delay-sensitive data such as voice t be dequeued and sent first" - the right answer is LLQ (as in the figure). In comments to figure the answer is "CBFWQ" - it is wrong.
Good luck!
I have passed the exam yesterday with score 1000 ,dump is totally valid and very thanks to mohamed for supporting and guidance in labs.
input direction?
A.Traffic matching the "MARKING2" class-map will be marked with qos-group 5
B.Traffic matching the "MARKING1" class-map will be marked with MPLS EXP 5
C.All incoming packets not matched bythe"MARKING1" class-map will be dropped
D.All incoming packets with the DSCP EF marking with be marked with MPLS EXP 0
Correct Answer: B
Issue: show policy-map interface gi0/0
First find out which policy-map is applied (it called something like QOSPOLICY1)
A is wrong. Class MARKING2 is indeed defined but not applied to that policy-map. There are two class-maps applied MARKING1 and class-default. Both will mark the traffic with MPLS EXP values.
default:
set mpls experimental imposition 0
MARKING1
set mpls experimental imposition 5
Therefore B is correct.
the last choice is wrong bec if you issue the command show class-map and check the "MARKING1" class-map, you will notice "match ip dscp ef", the policy-map will then mark it with exp 5 not 0.
Issue on PE8: show mpls forwarding-table , find prefix 10.0.2.1 and you will see there under outgoing Label "Pop Label" (This is actually logic because the prefix is directly connected and therefore the packet will forward without label). If the router should forward any packet to that prefix, the packet should be received with Local label on PE8 (Local Label = 35), the router will remove it and forward it without Label.
The Answer is Pop label 35.
4-From the PE8 router, how many total prefixes for have an incoming local label assigned (including the impnull)?
On PE8 issue: show mpls ip binding summary and look at "assigned in labels". That value is the correct answer NOT "learned out label".
The correct answer is 21.
100% dump valid only options have been tweaked and i got 72Qs.
Thanks Mohammed for your sharing.
Best of luck..
Follow my instruction to get the best result.
MM Questions = All answers are correct
DD Questions = All answers are correct
---------------------------------------------------------------------------
Regarding Labs:
1- On the PE8-router what is the label value used to reach the 10.7.1.1/32 network prefix
Answer: Issue on PE8: show mpls forwarding-table
Look for the "Outgoing Label" not the "Local Label" for the prefix 10.7.1.1/32. You will notice that the Label value is 16024.
2-On P2 IOS-XR router what is targeted LDP hellos hold time on LDP session with 10.0.1.1:0 LDP ID?
Answer: 90 sec.
Issue on P2: show mpls ldp discovery (details).
Ps: The command show mpls ldp parameter is not Implemented.
Look at the end, you will see the hello and the holdtime values for the target neighbour. Be careful he is asking for "targeted LDP hellos hold time". No other command will work!!! At the end of the show result you will see something looks like the following:
LDP discovery sources:
Targeted Hello 10.0.2.1 -> 10.0.1.1 active, passive;
Hello: 30 sec
holdtime: 90 sec
All questions are the same, but same wrong answer.
anyway that dump will help to pass.
Many thanks.
Thanks Mohammed.

I Passed Yesterday.
But Around 8 answers Wrong.
I have passed the exam yesterday with score 1000 ,this exam is totally valid ,Also i would like to thank mohamed for his guidance and support at labs.
answers are well shuffled
got 9XX
The LABs have different answers (MPLS LABBEL numbers,etc) but if you know the commands you can find them easily.
1- the order of answers are variable, so be sure that you understand and memorize the correct answers
2- some of the simulators answers are wrong, so you need to valdate answers in exam
some one having the material to prepare this please share it's urgent cuz i see every exam have three same books on official site .so any video tutorials are preferred
thanks
Hamdollah passed today and scored 968 , this dump is still valid .
