Share your ARCH Experience

bd what time is ur exam tomorrow .

@Kash
10:00 am GMT+4.

identical to 802.1W
assures one spanning tree insidence per bridged network regard less of no of Vlans
provides seperate instance of 802.1w for each VLAN
Cisco STP enhancement provices seperate 802.1D spnnaing tree insatnce for each VLAN
Original 802.1D version providing loop free topology

i hope u know the answers

@bd u r in india or somewhere closer ?, do u mind sharing some information in detail after exam , I will be online .

@Kash
Hmm, I thought I answered already about that, may be glitch. I am from Russia, Western part. Yep, I will try to share some information after exam, when I back to home. But I am not optimistic about tomorrow, very difficult exam, very strange some questions and I am tired with this.. :(

dont worry dont cramm
doo D&D
i have put main 20 Q and Ans on the top rest will be fine .

all the best bd i will be back after 3 hours now , while doing exam see the answers you choose all the best

Many thanks, Kash and others guys :)

5.8
QUESTION NO: 139

As an experienced technician, you are responsible for Technical Support. A customer calls to ask the best signal level and noise level for cell phone. How to respond?
A. -40dBm signal and -90dBm noise
B. -50dBm signal and -90dBm noise
C. -30dBm signal and -90dBm noise
D. -20dBm signal and -90dBm noise
Answer: B
This is a little strange, because “…Cisco recommends that the cell edge be -67 dBm and the SNR be 25 dB using a data rate of 11 Mbps..” So, ans B seems to be the “most” right answer among others?

5.8
QUESTION NO: 144

What are disadvantages to storage directly attached to the application servers? (Choose three.)
A. reliability
B. scalability
C. redundancy
D. manageability

Answer: A,B,D
May be B,C,D?

bd I would say stick with ABD on Q 144

Important information about Q249.
Which two of these correctly describe asymmetric routing and firewalls? (Choose two.)
A. only operational in routed mode
B. only operational in transparent mode
C. only eight interfaces can belong to an asymmetric routing group
D. operational in both failover and non-failover configurations
E. only operational when the firewall has been configured for failover

“…Cisco IOS Firewall does not offer active-active firewall capability. This limits Cisco IOS Firewall’s use in asymmetric routing deployments, as routing must be sure to maintain the same return path for traffic that was used at the ingress path…”
http://www.cisco.com/en/US/prod/collateral/vpndevc/ps5708/ps5710/ps1018/white_paper_using_cisco_ios_zone_based_classic_fw.html
This mean, that “D. operational in both failover and non-failover configurations” is not good ans.

So may be A and C.

“…In failover configurations, return traffic for a connection that originated on one unit may return through the peer unit…”
and
““…Cisco IOS Firewall does not offer active-active firewall capability. This limits Cisco IOS Firewall’s use in asymmetric routing deployments, as routing must be sure to maintain the same return path for traffic that was used at the ingress path…”
and
“..Cisco IOS® Firewall offers features that address stateful failover security requirements, but specific recommendations must be observed for network design and implementation when Cisco IOS Firewall is used for stateful inspection of IP traffic in non-failover environments…”

http://www.cisco.com/en/US/prod/collateral/vpndevc/ps5708/ps5710/ps1018/white_paper_using_cisco_ios_zone_based_classic_fw.html

I am confused now

If consider last:
“..Cisco IOS® Firewall offers features that address stateful failover security requirements, but specific recommendations must be observed for network design and implementation when Cisco IOS Firewall is used for stateful inspection of IP traffic in non-failover environments…”
– “D. operational in both failover and non-failover configurations”
is still right…

bd dont get confused wel all agreed that
Q249 C , D

wish u all the best
i would wait to hear the good news … Tomorrow morning

wish you luck guys, all the best

I can’t wait till you update guys! come on! give us good news :-)

Multicast dnd is wrong !!
Anycast uses sdp
and link local is the bottom one

hi guys, who pass ARCH 2.1 exam. Which materials is actual. If you have some books, please share!!!

@victor
Everything was above 50%. Security and advanced Ip was 67%

I’ll see if I share the answers that I came up with when I studied some time later today. AT is very good with the questions. Answers are not nearly as good. The multicast d&d is wrong, as Mcaster indicates. There’s also another d&d that is definitely wrong. I thought the exam was tough, but surely i’m not the only one who passed?

@Kash….Wats ur score??? How was t exam…Do share ur experience!!!! Awaiting eagerly…

So what’s the othe d&d that’s wrong gyrop
ospf lsa timers one , have you got that already

Oooo, I am passed !! Yeeeeee!! About 800/1000

So..
1) Were 2 new questions about filtering. Very simple questions. Like example: “Choose 2 filtering methods in the list” EIGRP Stub and so on.
2) Others qns were are from 5.8.
3) Was again question with 2 the same answers. I commented this again…
4) In QUESTION NO: 7 D&D I changed my answer.
STP – enable spec on the edge
TRUNKS – manually prune
UDLD – use spec on fiber-optic
Etherchannel – …power of 2..
VSS – ensure that an individual link failure will not result in an STP failure.

I think, this is more good answer.. Because “old answer’s version”, where we decided “VSS – enabled spec on the edge” – seems to be strange answer for me. VSS take care itself about link failure. May be I am right, may be not..

5) All others answered like Kash summarized 20 qns on the page 4.
6) Section “Designing advanced IP addressing and routing solution..” is still low, about 35%. But others sections now better, about 85%.
7) Many thanks to all guys for participation in discussions about questions!
8) Site admin, I hope you will somehow summarize our work. Result should be on the top.

Victor Can you work out 3 D&D answers please for me .
OSPF
MULTICAST
and
VSS one

guys i am leaving for exam in 2 Hours time So going through the questions

Q243 answer is C , D

Congrats bd i hope its good day start

In my exam were are D&D:

QUESTION NO: 3 DRAG DROP about VPN
QUESTION NO: 7 DRAG DROP – already wrote my answer to this one
QUESTION NO: 15 DRAG DROP about firewall
QUESTION NO: 27 DRAG DROP about RP model

From Kash’s list were are:
Q9 – I answered AD, may be wrong
Q19 – I answered A
Q40 – D
Q42 – B
Q49 – D,F
Q51 – A, C
Q56 – C
Q59 – I answered C, but as you know I prefer A.
Q267 – C, D

Others were simple questions with obvious answers.

@Kash
Thx :)

@Mcaster thanks for sharing DD answer

@bd

do u mind sharing some more questions u seee what Drag and Dropp
your this VSS sounds right to meee but i am trying to figure out …
any one else can please cross check

@bd

Q59 – I answered C, but as you know I prefer A.

how much u score in this

you got this wrong
QUESTION NO: 27 DRAG DROP about RP model
as Mcaster has already spotted problem

@bd

congrats!

Pedram if you get time can you work out the VSS thing D&D

@Kash
>do u mind sharing some more questions u seee what Drag and Dropp

About all my D&D I already answered.
Others qns were are simple, from 5.8 like:

QUESTION NO: 1
Which of these Layer 2 access designs does not support VLAN extensions?

or

QUESTION NO: 6
Which of these technologies is characterized as being a multipoint Layer 2 VPN that connects two or more customer devices using Ethernet bridging techniques?

or

QUESTION NO: 8
Why is STP required when VLANs span access layer switches?

and so on..

> how much u score in this
In sections? I answered, Section “Designing advanced IP addressing and routing solution..” is still low, about 35%. But others sections now better, about 85%.
Total is 802/1000.

@Pedram thx!
@Kash
I think my version of D&D answer about VSS is good enough, because this is strange to hear “VSS in the edge only”. VSS is a system that can control link failure itself, and for STP more likely to say “STP in the edge”.

with Q42 i will go with C, I don’t like “best” and “only” words in B

thanks … bd,
@ Pedram , i cross check with couple of industry guys this question.

bd

I think u miss point from Multicast D&D
and Q no 9 :)

What u answer for Q 17 i am still confuse between C and A but i am more towards A

@Kash
I agree with bd on D&D about VSS

@bd

Q9 has same typos on the real exam? “dual horning” in A, probably “learned router” in C

thanks that VSS thing seems making sense … bd this thing saved yu :)

@ Kash

Q42 for me C makes a very strong statement without doubt and says it doesn’t have any word like “best” and “only”; are you really believe that the “only” place for route summarization is on the edge to remote site or site-to-site VPN networks?

ref self-study v2, page 63 “It is a recommended practice to configure route summarization at the distribution layer”
“Summarization at the distribution layer optimizes the rerouting process.”

and consider that bd got only 35% on that part

huum you may be right , Let me go through it agian
but bd also missed multicast D&D which would be big
he also missed question no 9 as well

Q42, for me IGPs are superior to route filtering and I clearly remember I configured EIGRP on a ppp link between two buildings to avoid RIP crazy updates on an always congested WAN link long time ago

@Pedram this question dont fall under IP Domain
and one mre thing
PAge 112
after readin this do you this IGP is superior to route filtering

Remote sites generally are connected with lower bandwidth than is present in the network core. Remote sites are rarely desirable as transit networks to forward network from one place to another. Remote sites typically cannot handle the traffic volume needed to be a viable routing alternative to the core network. In general, when core connectivity fails, routing should not detour via a remote site.

In OSPF, there is little control over intra-area traffic. LSAs cannot be filtered within an area. OSPF does not allow traffic to arbitrarily route into and then out of an area. The exception is area 0, which can be used for transit when another area becomes discontiguous.
With EIGRP, it can be desirable to configure EIGRP stub networks. This informs central routers that they should not use a remote site as a transit network. In addition, the use of stub networks damps unnecessary EIGRP queries, speeding network convergence. Filtering can help manage which parts of the network are available for transit in an EIGRP network.
With BGP, the most common concern about transit traffic is when a site has two Internet connections. If there is no filtering, the connections advertise routes. This advertisement can put the site at risk of becoming a transit network. This should not be a problem with two connections to the same ISP, because the autonomous system number is present in the autonomous system path. Based on the autonomous system path, the ISP router ignores any routes advertised from the ISP to the site and then back to the ISP.

35% on ip address section
go over your eigrp and ospf answers

eigrp less nei is better than stub

Ospf router is stub qbd tstub cant tell whats going on outside
but student guide says thats not important

@Kash
what is the section it is falling under?

@Pedram
>Q9 has same typos on the real exam? “dual horning” in A, probably “learned router” in C
No no, it was written without typos.

@Kash
>thanks that VSS thing seems making sense … bd this thing saved yu
Yep, this is it )) 1 more wrong answer and fail again ;(

@bd
can you tell us what are the sections of scores?

Any one clearify q17 and Q 9 ,

@Pedram
Design advanced enterprise campus networks – 86%
Design advanced IP addressing and routing solutions for enterprise networks – 33%
Design WAN services for enterprise networks – 75%
Design an enterprise data center – 85%
Design security services – 67%
May be that, my report list is not good printed :(
