Operations Questions
Here you will find answers to Operation questions
Question 1
Refer to the exhibit. Will redistributed RIP routes from OSPF Area 2 be allowed in Area 1?
A – Because Area 1 is an NSSA, redistributed RIP routes will not be allowed.
B – Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 5 LSAs in Area 0 and passed on into Area 1
C – Because NSSA will discard type 7 LSAs, redistributed RIP routes will not be allowed in Area 1
D – Redistributed RIP routes will be allowed in Area 1 because they will be changed into type 7 LSAs in Area 0 and passed on into Area 1
Answer: A
Explanation
Because Area 1 is a Not-so-stubby-area (NSSA), we can inject EIGRP routes into the OSPF NSSA domain with the creation of type 7 LSAs. Redistributed RIP routes are not allowed in Area 1 because NSSA is an extension to the stub area (recall that a stub area does not accept external route unless it is connected through a ASBR, doing that will make it become a NSSA). The type 7 LSAs are converted to Type 5 LSAs when flooded into Area 0 by the ABR router.
Question 2
Study this exhibit below carefully. What is the effect of the distribute-list command in the R1 configuration?
A – R1 will permit only the 10.0.0.0/24 route in the R2 RIP updates
B – R1 will not filter any routes because there is no exact prefix match
C – R1 will filter the 10.1.0.0/24 and the 172.24.1.0/24 routes from the R2 RIP updates
D – R1 will filter only the 172.24.1.0/24 route from the P4S-R2 RIP updates
Answer: C
Explanation
The command “distribute-list 10 in Serial0″ will create an incoming distribute list for interface serial 0 and refers to access list 10. So it will permit routing updates from 10.0.x.x network while other entries (in this case the 10.1.0.0/24 and 172.24.1.0/24 networks) will be filtered out from the routing update received on interface S0.
Question 3
Which three route filtering statements are true? (Choose three)
A – After the router rip and passive-interface s0/0 commands have been issued, the s0/0 interface will not send any RIP updates, but will receive routing updates on that interface.
B – After the router eigrp 10 and passive-interface s0/0 commands have been issued, the s0/0 interface will not send any EIGRP updates, but will receive routing updates on that interface
C – After the router ospf 10 and passive-interface s0/0 commands have been issued , the s0/0 interface will not send any OSPF updates, but will receive routing updates on that interface
D – When you use the passive-interface command with RIPv2, multicasts are sent out the specified interface
E – When you use the passive-interface command with EIGRP, hello messages are not sent out the specified interface
F – When you use the passive-interface command with OSPF, hello messages are not sent out the specified interface
Answer: A E F
Explanation
Passive-interface command is used in all routing protocols to disable sending updates out from a specific interface. However the command behavior varies from one protocol to another”
- In RIP, this command will not allow sending multicast updates via a specific interface but will allow listening to incoming updates from other RIP speaking neighbors. This means that the router will still be able to receive updates on that passive interface and use them in its routing table.
In EIGRP and OSPF the passive-interface command stops sending outgoing hello packets, hence the router can not form any neighbor relationship via the passive interface. This behavior stops both outgoing and incoming routing updates.
Question 4
Router RTA is configured as follows:
RTA (config)#router rip
RTA(config-router)#network 10.0.0.0
RTA(config-router)#distribute-list 44 in interface BRIO
RTA(config-router)#exit
RTA(config)#access-list 44 deny 172.16.1.0 0.0.0.255
RTA(config)#access-list 44 permit any
What are the effects of this RIP configuration on router RTA? (Choose two)
A – no routing updates will be sent from router RTA on interface BRIO to router RTX
B – router RTA will not advertise the 10.0.0.0 network to router RTX
C – the route to network 172.16.1.0 will not be entered into the routing table on router RTA
D – user traffic from the 172.16.1.0 network is denied by access-list 44
E – the routing table on router RTA will be updated with the route to router RTW
Answer: C E
Explanation
Distribute list are used to filter routing updates and they are based on access lists. In this case, an access list of 44 was created to deny the route from network 172.16.1.0/24 so this route will not be entered into the routing table of RTA. But the route from RTW can be entered because it is not filtered by the access list
A and B are not correct because the distribute list is applied to the inbound direction of interface BRI0 so outgoing routing updated will not be filtered.
D is not correct because distribute list just filters routing updates so user traffic from network 172.16.1.0 will not be denied.
Question 5
Look at the following exhibit. Which of the following correctly states the routes to be redistributed into OSPF? (Choose two)
A – The network 10.0.10.0/24 will be allowed and assigned a metric of 200
B – All networks except 10.0.0.0/8 will be allowed and assigned a metric of 200
C – The network 172.16.0.0/16 will be allowed and assigned a metric of 200
D – The network 192.168.1.0 will be allowed and assigned a metric of 100
Answer: C D
@digitaltut
What abt the these questions mentioned above and on the right side of this site? Are all these updated questions?
Many thnks in advnce fr ur support!
Question 5:why C is right ?? who can explain to me
172.16/16 is not part of access-list 10, access-list 20 or access-list 30. It will therefore match route-map statement 30. Route-map 30 is a route-map without a match-clause. A route-map statement without a match-clause matches everything, so also 172.16/16. It will therefore get metric 200.
@digitaltut
Hi well Question 5 should be B and C since D cannot be correct because route-map rip-in permit 10 have a match in an AND logic so it’s imposible that exist a route to both 192.168.1.0/24 and 10.0.10.0/24 at the same time. For that route-map to apply both access-list must be matching and in this case that only would occur with overlapping access-lists.
ohh sorry it’s right my eyes are failing me it’s an or statement in the route-map
kinda consideration….
@digitaltut, i think you are in wrong!
The route-map rip-in permit 10 has a OR logic on the match command, which means that route map has to match access-list 10 OR access-list 20. So the right answers are C and D
For refference look here:
◦If a match command refers to several objects in one command, either of them should match (the logical OR algorithm is applied). For example, in the match ip address 101 121 command, a route is permitted if it is permitted by access list 101 or access list 121.

can someone please clarify question 121. 2 default gateway’s set. one 140.140.0.0 and 130.130.0.0. There are show run and show ip route commands issued. the answer is a route to the 140.140.0.0 does not exist in the routing table but we see it 116.16.34.0/28 as directly connected
Hi Guys
I am preping for my MPLS 642-611 exam. Can someone please point me to the right directions for dumps / labs. I have old dumps but i have no idea how exam labs looks like. Any help will be great.
Thanks.
Q4 : Why is there no auto summarization at network boundaries for this question ?
All, the answers for Q5 should be AC not CD, because as soon as route-map 10 finds a match for ACL 10, it will stop there and will not check for any matches for ACL 20. If we had the option to choose three answers, then the correct ones would have been ACD.
Please can someone verify if questions on is-is stil lcome out in the route exam.
I’m woried ‘cos is-is is no longer in the route syllabus but dumps still have questions on is-is
thanks
I have made all of the 642-902 Test sims in a GNS3 format, just email if you want a copy at cciersbound@yahoo.com
Later,
CCIERSBound
P.S. I just passed my Route exam on the Nov 13th, 2010 with a 986 and there were no questions on IS-IS. I had 50 questions and the score required to pass was 790
@Bill
Dont see any ISIS today
However, I also didnt get these 5 questions here too
Hi CCIERSbound…
I have send 2 mails and you have not sent me the GNS3 Format. :(
Thanks and Regards

hi all
i have passed yesterday with score 966/ 1000
the passguide 3.37 is valid with 90 %
thank to digital tut and to everybody
this site is really great
all labs from here.
@knowlegde guru: A is wr0ng, because of wr0ng metric of 200. Right anwer is CD..
Anyone guide about the topics in Exam(which routing protocol used) :—-
EIRGP,RIP,OSPF,BGP
Please clear about IS-IS, IGP, that are not include in Route Exam
a bit unclear question
the redistribute command misses SUBNETS which is required for ospf redistribution to allow any classless network to be redistributed into OSPF… although, it taking this requirement as pre-requisite answers are correct…
please explain q.4
Q4-
RTA (config)#router rip
RTA(config-router)#network 10.0.0.0
RTA(config-router)#distribute-list 44 in interface BRIO
RTA(config-router)#exit
RTA(config)#access-list 44 deny 172.16.1.0 0.0.0.255
RTA(config)#access-list 44 permit any
‘distribute-list 44 in interface BRIO ‘ line means when there is an update coming in (check word ‘in’ in the line) on BRIO interface (check interface in line) then allow only which is allowed through access-list 44. So access-list 44 says deny 172.16.1.x and allow rest so 172.16.1.x will be denied and rest will be allowed and in this diagram rest that come on BRIO is RTW router link/prefixes. If they have mentioned specific numbers/network then we can put filter to that also using same ACL.
i undestand this 1
bt thing is that wen we erforming the distribute list we hve to filter wat we permit ………
so we permit anything except the 172.16.1.x
means all are filterd except 172.16.1.x ……
am i right ?
shz
Only bcos of route-map rip-in permit 30 statement all other IP addresses denied by the other two statements will be permitted.hence 172.16.x.x is permitted and assigned the metric 200
sorry a slight change in the sentence…
Only bcos of route-map rip-in permit 30 statement all other IP addresses for whom rules 10 and 20 dont apply will be permitted.hence 172.16.x.x is permitted and assigned the metric 200
hi! is 11th question from gogy, section redistribution, we are required to filter only default network between two EIGRP ASs, and there is route-map in redistribute command which uses ACL:
a) access-list 100 permit ip 0.0.0.0 0.0.0.0 0.0.0.0 0.0.0.0
b) access-list 100 permit ip host 0.0.0.0 any
c) access-list 100 permit ip any host 0.0.0.0
Option c) is marked as correct, but i doubt correct answer is a), any opinion?
Thanks
hi all,
i am planning to take Route(642-902)exam at coming monday i.e 28 march ,can anybody tell me DHCP ,isis and multicast topic is still in new CCNPV6 Route Exam syllabus, because i found many question on DHCP,multicast and isis in new dumps for ROUTE exam. If anybody had cleared ROUTE exam between
last 2 ,3 weeks I request to you
plz suggest your view and experiance, it will help me lot…..
@bharti: if you clicked on http://www.digitaltut.com/route-faqs-tips you would have found out that they are not part of the 642-902 exam. Also looking through the previous postings would have gotten your answer as well.
Any one see the questions about Router Memory?? Anyone remember that?
Hi all,
Can someone please explain what i’m doing wrong at this question from GOGY?
Thanks in advance.

@ Allex1, even if you set to type 1 i think cost will still be same since its one hop away
best bet would be to influence with route map i think
but its not an option and you need to select “best response” from given scenarios only
anyone else has any insight on this one??
Doubt regarding Question-4
In the explanation its saying that :-”D is not correct because distribute list just filters routing updates so user traffic from network 172.16.1.0 will not be denied.”
But “access-list 44 deny 172.16.1.0 0.0.0.255″ denies everything from 172.16.1.0 network ,then how come user traffic from this network is allowed inside to RTA…?
Pls can any one in d house give me a printable version of CCNP Route Official Certification Guide or any one. my contact is akin_joseph82@yahoo.com
Thanks
The distribute-list 44 in rip configuration mode works together with access-list 44 in global configuration mode. this access-list 44 will therefore deny routing updates only and permit all other traffic since there is a permit any statement.
@Allex1
The Last answer is correct because none of the options presented would make the route to 172.16.54.0 go through router B. The only way to do that would be through a route-map. For example: Apply this route-map to router C
router ospf 1
log-adjacency-changes
redistribute eigrp 1 subnets route-map change-metric
network 10.0.0.0 0.255.255.255 area 0
access-list 10 permit 172.16.54.0
route-map change-metric permit 10
match ip address 10
set metric 40
!
route-map change-metric permit 20
Since none of the options in the question mention the option for a route-map or changing the route metric for 172.16.54.0, the correct answer would be the last one which is “None of these solutions will fix this…..”
@zBn
When you create the access-list 44, it has to be applied to some interface remember? because we have not applied this access-list 44 to any interface using the “ip access-group 44 in” command it will not apply to user traffic arriving on the BRIO interface and hence not filter any traffic from 172.16.1.0.
The access-list 44 is only being used by the distribute list to filter the route 172.16.1.0 from the routing updates received on that interface.
Hope that clears the doubt.
@ blayne March 17th, 2011
I have tried the first three options in the question and they all advertise the default route. Try it in GNS 3 :) they all work
let me know if you want the running config for this.

Hello guys..
does anyone has ccnp route 642-902 cbt, pass4sure any dumps or GNS3 LAB?.
kindly send me links on
shariq2009@live.com or u can send here as well.
GNS3 LAB is very important.. kindly send me links.
Thanksss
Hi All,
can please somebody again explain why in Q5, “C” is correct ?
thank you
The last route map (30) mean that any other address will be allowed and the metric will be signed because there is no match address..This for any adderss not included in 10,20

I was playing an app on Facebook (Graffiti) and my Mac warned me that the page may contain malware. Of course I ignored it because I wanted to draw more with the app, and when i was done the page scrolled up by itself and my curser moved across the screen a bit on its own. Does my Mac have a virus? are there any built-in features that could be of assistance? are there any anti-virus programs safe to use on my Mac?
@HG Because 172.16.0.0/16 doesn’t fall under either route-map line 10 or 20, route-map line 30 covers everything else, and it sets the metric to be 200.
plz help!!! anyone who had a CCNP switch and router VIDEOS, plz forward them in this email address sthandiweg@webmail.co.za, i will preciate
hey some body pls send me prepared gns3 labs for route 640-902. i’d be much grateful. Hey CCIERSBound could you help me? i also sent u an email. :-)
help mee pleaseeeeee!!!!

Hi,
I have one doubt regarding redistribution ques:
You have implemented mutual route redistribution b/w ospf and eigrp on a border. when checking the routing table on one of the eigrp routing domain, you are seeing some, but not all of the expected routes.What should you verify to troubleshoot this problem? select the best response :
answer is , The missing OSPF routes are pest in routing table of border router
But the options also have , The subnet keyword on the border router in the redistribute ospf command.
Also , in the same ques when requiring two answers lists the second option also,
Can i anyone clarify that ,
Regards,
Arvind
for Q5 —> Can anyone confirm that (D) is the ANSWER and why ?
I know C is the answer but just not sure what the other answer is ?
Thx.
Hi JS…
route-map 10 permits both acl 10 & 20.
acl 20 permits 192.168.1.0/24 .
So, D is a correct answer.
Because 192.168.1.0/24 network matches route-map 10 & metric 100 is set.
Hello Friends,
I just started to study the ROUTE test after taking almost two years off from passing the CCNA. I am planning to take the ROUTE test in two months. Are the Sims, Drag and Drop, Questions, and everything else on this site still valid for the ROUTE test?
Thank you all!
