HSRP Hotspot
Question:
- DSW1( Distribute switch 1) is the primary device for Vlan 101, 102, 105
– DSW2 ( Distribute switch 2) is the primary device for Vlan 103 and 104
Question 1:
During routine maintenance, it became necessary to shutdown G1/0/1 on DSW1. All other interface were up. During this time, DSW1 remained the active device for Vlan 102′s HSRP group. You have determined that there is an issue with the decrement value in the track command in Vlan 102′s HSRP group. What need to be done to make the group function properly?
A. The DSW1′s decrement value should be configured with a value from 5 to 15
B. The DSW1′s decrement value should be configured with a value from 9 to 15
C. The DSW1′s decrement value should be configured with a value from 11 to 18
D. The DSW1′s decrement value should be configured with a value from 195 to less than 205
E. The DSW1′s decrement value should be configured with a value from 200 to less than 205
F. The DSW1′s decrement value should be greater than 190 and less 200
Answer: C
Explanation:
The question clearly stated that there was an issue with the decrement value in VLAN 102 so we should check VLAN 102 on both DSW1 and DSW2 switches first. Click on the PC Console1 and PC Console2 to access these switches then use the “show running-config” command on both switches
DSW1>enable
DSW1#show running-config
DSW2>enable
DSW2#show running-config
As shown in the outputs, the DSW1′s priority is 200 and is higher than that of DSW2 so DSW1 becomes active switch for the group. Notice that the interface Gig1/0/1 on DSW1 is being tracked so when this interface goes down, HSRP automatically reduces the router’s priority by a configurable amount, in this case 5. Therefore the priority of DSW1 goes down from 200 to 195. But this value is still higher than that of DSW2 (190) so DSW1 remains the active switch for the group. To make DSW2 takes over this role, we have to configure DSW1′s decrement value with a value equal or greater than 11 so that its result is smaller than that of DSW2 (200 – 11 < 190). Therefore C is the correct answer.
Question 2:
During routine maintenance, G1/0/1 on DSW1 was shutdown. All other interface were up. DSW2 became the active HSRP device for Vlan101 as desired. However, after G1/0/1 on DSW1 was reactivated. DSW1 did not become the active HSRP device as desired. What need to be done to make the group for Vlan101 function properly?
A. Enable preempt on DSW1′s Vlan101 HSRP group
B. Disable preempt on DSW1′s Vlan101 HSRP group
C. Decrease DSW1′s priority value for Vlan101 HSRP group to a value that is less than priority value configured on DSW2′s HSRP group for Vlan101
D. Decrease the decrement in the track command for DSW1′s Vlan 101 HSRP group to a value less than the value in the track command for DSW2′s Vlan 101 HSRP group.
Answer: A
Explanation:
Continue to check VLAN 101 on both switches…
We learned that DSW1 doesn’t have the “standby 1 preempt” command so it can’t take over the active role again even if its priority is the highest. So we need to enable this command on VLAN 101 of DSW1.
Question 3:
DSW2 has not become the active device for Vlan103′s HSRP group even though all interfaces are active. As related to Vlan103′s HSRP group. What can be done to make the group function properly?
A. On DSW1, disable preempt
B. On DSW1, decrease the priority value to a value less than 190 and greater than 150
C. On DSW2, increase the priority value to a value greater 241 and less than 249
D. On DSW2, increase the decrement value in the track command to a value greater than 10 and less than 50.
Answer: B or C
Explanation:
The reason DSW2 has not become the active switch for Vlan103 is because the priority value of DSW1 is higher than that of DSW2. In order to make DSW2 become the active switch, we need to increase DSW2′s priority (to higher than 200) or decrease DSW1′s priority (to lower than 190).
Question 4:
If G1/0/1 on DSW1 is shutdown, what will be the current priority value of the Vlan105′s group on DSW1?
A. 95
B. 100
C. 150
D. 200
Answer: A
Explanation:
Below is the output of VLAN 105:
If G1/0/1 on DSW1 is shutdown, its priority will decrease 55 so, its value will be 150 – 55 = 95
Question 5:
What is the configured priority value of the Vlan105′s group on DSW2 ?
A. 50
B. 100
C. 150
D. 200
Answer: B
Explanation:
Below is the output of VLAN 105 of DSW2:
We don’t see the priority of DSW2 so it is using the default value (100).
Question 6:
During routine maintenance, it became necessary to shutdown G1/0/1 on DSW1 and DSW2. All other interface were up. During this time, DSW1 became the active device for Vlan104′s HSRP group. As related to Vlan104′s HSRP group, what can be done to make the group function properly?
A. On DSW1, disable preempt
B. On DSW2, decrease the priority value to a value less than 150
C. On DSW1, increase the decrement value in the track command to a value greater than 6
D. On DSW1, disable track command.
Answer: C
Explanation:
The question asks us how to keep the active role of DSW2. From the outputs, we learned that if both interfaces G1/0/1 of DSW1 and DSW2 are shutdown, the priority of DSW1 will be 150 – 1 = 149 and that of DSW2 will be 200 – 55 = 145 -> DSW1 will become the active switch.
The main point here is that we have to configure so in such a way that when both interfaces G1/0/1 of DSW1 and DSW2 are shutdown, the priority of DSW2 is still greater than that of DSW1. Therefore the priority value of DSW1 should be smaller than 145, or we have to configure the decrement value of DSW1 to a value greater than 6 ( 6 = 150 – 144) -> C is the correct answer.
Notice: To keep the active role of DSW2, we can disable “preempt” on DSW1 (answer A) so that it will not take over the active role when DSW1 is downed but it also means that VLAN 104 will not have active switch -> VLAN104 will fail.
Why is this called “Hotspot”?
that’s very good hotspot.
can you insert the complete running-config somewhere at the top?

Without the configs BEFORE the answers we cannot attempt this.
I suggest you add the configuration comment before the answers, because we cann’t work this out without runing config.
Hi,
For question 3, the answer should be C.
If both interfaces down, DSW1 is 190 while DSW2 is 191-199
If the answer was B, DSW1 will be 140 to 179 while DSW2 will be 140.
@bob
Why r u thinking of when both interface down while question says that all interface are active ?
please explain…
@ Ashraf, Both B and C seems to be correct answers. but my experince with the ccna exams are that there is just one answers that is “the best”
And IF both interfaces goes down, then anwers B is beter then C (i think)
@bob
But when both interfaces goes down, than this group cannot function properly acording to the question !!!!!!!!!!!
The question is to make DSW2 the active device for vlan 103.
What I meant was in the event that DSW1 or 2 went down and came back up.
But C is the best answer. And I only replied once to this, so don’t get too agitated. Cheers.
If the aim of the question is to make DSW2 active then both B&C are correct.
But if we should assume that we want HSRP to work correctly and fail over to DSW1 when the gig link fails – then answer B is correct, because if we increase the priority on DSW2 to >241 & <249 (answer C), DSW2 priority will always be greater than 190 and they will never fail over…
Answer B allows DSW2 to be active, and on failure allows DSW1 to become active.
If answer B
if a both links goes down dsw1 priotity 140 and dsw2 priority 140, but ip of dsw2 highest and DSW2 will active router
If answer C
DSW1 priority 190, DSW2 priority 191 and DSW2 will active router.
anybody now best answer?
For case B
If DSW1 priority is 189 – 10 = 179
DSW2 priority is 190 – 50 = 140 ->Both links are down DSW1 is Active
For Case C
DSW1 priority is 200 – 10 = 190
DSW2 priority is 242 – 50 = 192 -> Both links down and DSW2 is Active
I think C
Notice in the Scenario this statement:
– DSW2 ( Distribute switch 2) is the primary device for Vlan 103 and 104
For Question 3, I agree w/ Bob:
Question 3:
DSW2 has not become the active device for Vlan103′s HSRP group even though all interfaces are active. As related to Vlan103′s HSRP group. What can be done to make the group function properly? (PROPERLY)
If gig1/0/1 were to fail on DSW2, we would want DSW1 to take over as Master.
Either B or C would work for this.
However….
If gig1/0/1 on DSW1 failed, we would want DSW2 to remain/take the role as Master (since it was primarily the master anyway).
For this to work, answer C would have to be the correct answer.
Original Priority:
DSW1: 200
DSW2: 190 (+51 = 241) <— DSW2 would correctly be Master normally.
After DSW2 gi1/0/1 fails
DSW1: 200
DSW2: 140 (+51 = 191) <— DSW2 would become standby during failure.
After DSW1 gi1/0/1 were to fail (hypothetically):
DSW1: 190
DSW2: 140 (+51 = 191) <— DSW2 would become Master now that "all things are equal"
last week our group held a similar talk on this topic and you point out something we haven’t covered yet, thanks.

am looking next friday to take SWICHING exam can any one tell me the lab questions
Hello, question 3 is wrong. There is only ONE soltion which is B. Why? Because you missing the most important part of the qestion.
Scenario:
Switch.com is a small IT corportation, with enterprise network (access, distribution and core) switches that provide LAN connectivity from users PCs to coprorate servers. The distribution switches are configured to use HSRP to provide a high avialability solution as follow:
- DSW1 (Distribution Switch 1) is the primary device for VLAN 101, 102, 105
- DSW2 (Distribution Switch 2) is the primary device for VLAN 103,104
- A failure of GiagabitEthernet1/0/1 on the primary device should block the primary device from beeing the active device, UNLESS GIGABITETHERNET1/0/1 ON THE BACKUP DEVICE ALSO FAILED.
This is very important. Because for question 3.
When I would do C and raise the priority value greater to 241. Even if the line on DSW2 fails the priority of DSW2 would be 191. The priority of the DSW1 would be 190. So the switch would still have the active role if both switches have a line problem.
hope it helps,
good luck with your exams
Maybe the admin can put the scenario to the drawing?
@ aprisma,
C option seems correct. Setting priority of 241-249
Because if gig1/0/1 on DSW2 fails , then DSW2 priority >> 191-199
But still DSW1 priority is 200 so it will preempt the DSW2
And if both int gig1/0/1 on DSW1 & DSW2 fails, DSW1 priority will become 190 and DSW2 priority will be 191-199.
So we want that active router should be DSW2 in any case. So C is correct.
@matrix
You forget the scenario:
If DSW1 G1/0/1 fails DSW2 should take over. If also the G1/0/1 on DSW2 fails DSW1 should take over again.
So if DSW1 fails it has a priority of 190. If then also DSW2 fails it has a priority of 191-199. This is higher then DSW1. So DSW1 will NOT take over if both switches looses their G1/0/1 Interface.
I have posted ths scenario above.
cheers,
@matrix
Ok maybe you are right because
- DSW2 (Distribution Switch 2) is the primary device for VLAN 103,104
so in case that both are down DSW2 it should be the active device. The most difficult thing in that exam is understanding the text.
thanx, cheers
Hey, I can’t view your site properly within Opera, I actually hope you look into fixing this.
I agree with aprisma and Bob.
I sat last week for this exam (and didn’t pass) and had exactly this scenario.
The missing part of the scenario (added by aprisma) is very important to sort out the right answers.
My 5 cents…
Finally, an issue that I am passionate about. I have looked for information of this caliber for the last several hours. Your site is greatly appreciated.
show me
found your site on del.icio.us today and really liked it.. i bookmarked it and will be back to check it out some more later
Why is this called a Hotspot??
I think one of your advertisements caused my internet browser to resize, you might want to put that on your blacklist.
Top work always good to come across a really thoughtful site – I’ve bookmarked it.
I really enjoyed the post so I used my Digg account to digg it – should help you
Searched Google and ended up here – its good so I posted the link on my Facebook account !
Searched Yahoo/Bing and ended up here – its good so I posted the link on my Facebook account !
for Q4 at my exam today (there was no option for 95 instead they have it 45)
I wasted much of time on it to figure it out and I could not. Then I picked the 45 at the end.
I got 100% on this topic so I would assume this 45 on my exam was mistakenly entered.
The rest on this Lab is the same. So do not waste your time if you get encounter with the same issue.
Good Luck

Hello, guys.
I’ve passed today with score 901.
I have had an error on the exam in this question:
If G1/0/1 on DSW1 is shutdown, what will be the current priority value of the Vlan105′s group on DSW1?
A. 45
B. 100
C. 150
D. 200
Instead of correct priority 95 I’ve got wrong 45.
That’s why there wasn’t right answer.
I’ve written on the Comments for the question on the exam about that.
Please be careful on the exam and good luck.
I will be sure to post a link to this website on my blog. I’m sure my subscribers will find this post really useful.
Just to confirm….
Question 3. is C
B can’t be correct b/c if both links are down, DSW2 still needs to be active. The only way that can happen is if its priority is 241-249
This blog is very well written, keep up the good work!
Q3:
Why r some of you subtracting 10 from DSW1 priority? The question doesn’t have any value to decrement on DSW1. Should there be a 10?
I genuinely like your blog and i hope i will be able to make my mba web site looking like your.It is genuinely hard to get a hold on boog website especially if its mba.i am trying my best to make my visitor look good that i know good about mba and all related stuff. Thanks i love Hot mba.
Ateşli ve eğlence de sınır tanımayan escort kızlarımız ile tanışmak için daha ne bekliyorsunuz.
@ Anonymous
We subtract 10 because it is the default value for tracking decrements. If no value is specified (like DS2), 10 will be the amount.
DOX3003 : can you pls tell what are all you studied for the exam ccnp
also can someone pls update the latest version of the exam.. and what dumps do we need to study
Looking for good and free sim software.
Thanks in advance.
please send the info to gmoney5125@yahoo.com
For question 3. Answer is B.
DSW1 priority: 200
DSW2 priority: 190 – 50 = 140 (Decremented Value if Gig1/0/1 goes down)
In the scenario that DSW2 should be the Active device for VLAN103. The answer “On DSW1, decrease the priority value to a value less than 190 and greater than 150″ is the best answer.
DSW1: 151 – 189
DSW2: 190 – 50 = 140 (-50 is the decrement Value if Gig1/0/1 goes down)
This answer will ensure that DSW1 will only be the active active device for VLAN103 when Gig1/0/1 goes down. Making DSW2 the active at all time as long as Gig1/0/1 doesnt goes down.

what you answer on 3 question?
@B0yd
“”"This answer will ensure that DSW1 will only be the active active device for VLAN103 when Gig1/0/1 goes down. Making DSW2 the active at all time as long as Gig1/0/1 doesnt goes down.”"”
as i understand the same will be if we increase the sw2 priority, dsw2 will be active and when interface goes down priority will be (if we choose 245) 195 and the sw1 priority 200 (that will be active)
if both int goes down dsw2 will be primary because sw1 priority will be 185
(– DSW2 ( Distribute switch 2) is the primary device for Vlan 103 and 104) (dsw2 must be primary)
p.s. sorry for my english :)
p.s. i have scheduled exam on 16 march ;)
re Q3. past exam takers who have had this question, please confirm whether its a radio button or mutli choice check boxes?? Knowing Cisco there is only one Cisco answer!
I just passed 642-813 today and got 978.
The Q3 answer modify as follow:
B. On DSW1, decrease the priority value to a value less than 190 and greater than 150
C. On DSW2, increase the priority value to a value greater 200 and less than 209
…
So, the correct answer should be B.
Question 3:
DSW2 has not become the active device for Vlan103′s HSRP group even though all interfaces are active. As related to Vlan103′s HSRP group. What can be done to make the group function properly?
A. On DSW1, disable preempt
B. On DSW1, decrease the priority value to a value less than 190 and greater than 150
C. On DSW2, increase the priority value to a value greater 241 and less than 249
D. On DSW2, increase the decrement value in the track command to a value greater than 10 and less than 50.
Answer: B or C
For this question, I understand either B or C is correct. But which will be more accurate?
Question 6:
During routine maintenance, it became necessary to shutdown G1/0/1 on DSW1 and DSW2. All other interface were up. During this time, DSW1 became the active device for Vlan104′s HSRP group. As related to Vlan104′s HSRP group, what can be done to make the group function properly?
A. On DSW1, disable preempt
B. On DSW2, decrease the priority value to a value less than 150
C. On DSW1, increase the decrement value in the track command to a value greater than 6
D. On DSW1, disable track command.
Answer: C
For this question, I understand that disabling DSW1 preempt will guarantee that DSW2 is active. Is that right?

Hello
Are you agree with the question 250 of actual test (also present in pass4sure, p475):
http://www.scribd.com/doc/49586828/250/QUESTION-NO-250
For me C is not a correct answser because for group 2 (vip 192.168.1.2) catalist_A is the standby router. Am I wrong?
Thank you.
You have determined that there is an issue with the decrement value in the track command in Vlan 102s HSRP group. The DS1s decrement value should be configured with a value from 5 to 15B.
Thanks for the explanation.
What a great web log. I spend hours on the net reading blogs, about tons of various subjects. I have to first of all give praise to whoever created your theme and second of all to you for writing what i can only describe as an fabulous article. I honestly believe there is a skill to writing articles that only very few posses and honestly you got it. The combining of demonstrative and upper-class content is by all odds super rare with the astronomic amount of blogs on the cyberspace.
Hi All, just passed swithing exam with 850. I feel its not enough. Questions are from P4S and labs are aaa,lacp,eigrp (follow VIOS configuration docs which you will find in this website.I will post later the certain questions which has been slitly modifed than it looks in P4s. Greatful thanks to this perticular site Admins and all other Cisco engineers for their knldge share.

This question is in the exam.
Still valid as of today.
lovely questions…….go for it……before clicking on answers dont forget to verify it……i gpt all answers correct….:-)
To match the speed of VRRP you can change the hello timer to 1 second and the holddown timer to a value of 3. The default values for HSRP are hello 3 secs and holddown 10 secs.To really ramp up the speed of the failover you can define the timers in milliseconds!
Question 3:
I got 100% to this topic-> Answer C is the correct
ps: I have not got any question related to Lightweight AP…
Good Luck
I got this 6 questions for my today exam. 100% exactly same like what are showing here.
what is the correct order of packet cos priority? can anyone help me?
Hi i got this question in my exam today…i got 100% in this hotspot…only question 4 above was changed the priority was 100 & decrement was default…..rest were the same as above…thanx guys for helping….certprepare really helped me clear switching….
can any one help me with gns3 lab, i want to write my ccnp switch in this coming month, PLZ HELP!!! sthandiweg@webmail.co.za
can any body tell me, How much Question from voice or Wlan in Exam of switch.I takeover the exam in next week.

guys i feel confortable with hsrp hotspot
i think i have made a a step forward
Yes there should realize the reader to RSS my feed to RSS commentary, quite simply
Hi guys
I`ll make my exam next week, i want to know how much(generally) of question about wireless and voice appers on the exam ?
Already talked to some people and I was told not appear more than two questions from each topic, this is true?
Thank you
Are the hotspot options same as above or they can chnage the interface or priority or vlan number
pls can anyone help me a website where i can download switch dumps.
