Question 9 ; i think the answer should be the NAC framework
Question 18 l A B D E are correct …
A company is implementing an Identity Management solution with these characteristics:
existing Cisco ACS 4.0
Cisco Catalyst switches
minimal added investments
NAC Framework doesn’t work because they don’t want any added investments.
From Cisco Press CCDA OECG 3rd
pg 471
The NAC Framework is an integrated solution led by Cisco that incorporates the network infrastructure and third-party software to impose security policy on the attached endpoints.
The key section is “third-party software”.
IBNS uses 802.1x and a backend RADIUS server, like Cisco ACS.
So, IBNS is the only one that fulfills all of the customer requirements.
Question 12
When configuring switch-to-switch interconnections to carry multiple VLANs, set DTP to on/on with no negotiate to avoid DTP protocol negotiation. This tuning can save seconds of outage when restoring a failed link or node.
http://www.cisco.com/en/US/docs/solutions/Enterprise/Campus/HA_campus_DG/hacampusdg.html
@stefan
I agree with you at the on/on_no negotiate as the most correct. The key on saving time there is the “no negotiate” part. Of the answers provided, there are only two with “no negotiate” –> auto-to-auto or desirable-to-desirable. And only one of those will even make a trunk.
Q12
The question mentions DTP “to carry multiple VLANs for Dynamic Trunk Protocol?”.
And for E,there is no option in CatOS to configure des-des with nonego.
In other words, answer provided is correct
http://www.cisco.com/en/US/products/hw/switches/ps4324/products_tech_note09186a0080094713.shtml#dtp
Recommendation
Cisco recommends an explicit trunk configuration of desirable at both ends. In this mode, network operators can trust syslog and command line status messages that a port is up and trunking, unlike on mode, which can make a port appear up even though the neighbor is misconfigured. In addition, desirable mode trunk provides stability in situations where one side of the link cannot become a trunk or drops trunk state. Issue this command in order to set desirable mode:
set trunk mod/port desirable ISL | dot1q
Question 18
Which two of these are scalability benefits of designing a network that utilizes VPNs?(Choose two)
A. extends the network to remote users
B. allows networks to be set up and restructured quickly

Answer: C D
Question 12
In a Cisco CatOS switch, what is the recommended practice when configuring switch-to-switch intercommunications to carry multiple VLANs for Dynamic Trunk Protocol?
A. auto to auto_negotiate
B. auto to auto_no_negotiate
C. on to on_negotiate
D. desirable to desirable_negotiate
E. desirable to desirable_no_negotiate
F. disable Dynamic Trunk Protocol when operating in the distribution layer
Answer: C
Guys take a close look to the question. It is asking about scalability benefits, so eliminate cost benefits.
Question 18
Which two of these are SCALABILITY benefits of designing a network that utilizes VPNs?(Choose two)
A. extends the network to remote users
B. allows networks to be set up and restructured quickly
C. reduces dial infrastructure expenditures
D. reduces the number of physical connections
E. simplifies the underlying structure of a customer WAN
My answer: A and D
Question 12
In a Cisco CatOS switch, what is the recommended practice when configuring switch-to-switch intercommunications to carry multiple VLANs for Dynamic Trunk Protocol?
A. auto to auto_negotiate
B. auto to auto_no_negotiate
C. on to on_negotiate
D. desirable to desirable_negotiate
E. desirable to desirable_no_negotiate
F. disable Dynamic Trunk Protocol when operating in the distribution layer
There is a typing mistake…
it shoud be C. on to no_negotiate becouse on_negotiate is not exist.
So the wright answer is C from the dump is just a typing mistake.
Take care.
A campus network needs end-to-end QoS tools to manage traffic and ensure voice quality. Which three types of QoS tools are needed? (Choose three)
A. interface queuing and scheduling
B. congestion management
C. compression and fragmentation
D. bandwidth provisioning
E. traffic classification
F. buffer management
Answer: A D E
Why isn’t this A B E.
Congestion management is listed as one of the QoS and Bandwidth mechanism for VOIP and Video networks. p.555 Official Cert Guide 640-864.
Q6:
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/srnd/4x/42nstrct.html#wp1063074
I found this which would seem to state that 6 is correct as A D E.
Q3. Got to say that this is again not correct. Any failure of a single device HAS to have a convergence event. This preculdes
E. A link or box failure does not require routing protocol convergence.
Leaving options. One of these can be removed because it is always deterministic i.e. a routing protocol
A. It uses timer-based non-deterministic convergence.
So we’re left with
B. It is software-based, providing fast convergence to the remaining path.
C. Routes are not summarized from distribution to the core.
D. The Layer 3 redundant equal cost links support fast convergence.
with C being obviosly wrong. I suggest the answer is clearly B & D because BFD and neibour adjacencies are software based and cause fast convergence when failure is detected and ECMP means fast convergence times.
Thanks DSTUT.
Q5. This is clearly not EtherChannel as they are asking about medium office sized designs which require a two-tier approach therefore A is correct:
A. two-tier
Thanks.
Q6. Again it has to include the queuing and scheduling plus traffic classification, A & E. I would say congestion management is more of a QoS mechanism than simply throwing bandwidth at the probem so would go with B.
A. interface queuing and scheduling
B. congestion management
C. compression and fragmentation
D. bandwidth provisioning
E. traffic classification
F. buffer management
A, B, E.
Q5 is incorrect. I think the answer should be the letter A -> two-tier.
I totally agree with @lonsomeboy about question 6
A. interface queuing and scheduling
B. congestion management
C. compression and fragmentation
D. bandwidth provisioning
E. traffic classification
F. buffer management
A, B, E.
hi Guys regarding Q6, have you encountered this question in the real exam? Thanks, I’ll be taking my examination this week. Hope you can help me with this.
@ lonsomeboy = “Q3. Got to say that this is again not correct. Any failure of a single device HAS to have a convergence event”
The question and the graphic clearly show a failure of a LINK and not a DEVICE
@ lonsomeboy again and Julian = “Q5. This is clearly not EtherChannel as they are asking about medium office sized designs which require a two-tier approach therefore A is correct”
Yes medium size has two-tier design thus a collapsed core/distribution (L3 router) and an access layer (switch). The question is asking for the parameter of providing redundancy and higher bandwidth,……between these two tiers,….what could that be,…yay etherchannel. Which is a technology, the question asked for a topology or a technology. It is a good question, it tricks you if you don’t fully understand or read carefully.
@ lonsomeboy once more = “Q6. Again it has to include the queuing and scheduling plus traffic classification, A & E. I would say congestion management is more of a QoS mechanism than simply throwing bandwidth at the probem so would go with B.”
It isn’t throwing bandwidth at it, it is provisioning it, reserving it, having it ready to support a critical traffic source that is voice which requires realtime levels of transmission.
Someone even provided a link for you 2months before you claimed the answer was wrong. See Delta’s post on Oct 19th 2012
Be 100% certain, otherwise you end up confusing others with your own confusion.
Q6 ask: Which three types of QoS TOOLS are needed?
QoS tools are: Classification en marking, congestion management (queeing), shaping e policing, congestion avoidance, link-efficency and call admission control, from Cisco Qos exam certification guide.
The right answers are:
B. congestion management
C. compression and fragmentation (link-efficency)
E. traffic classification
Can I use my CCNA Wireless Voucher over CCDA Exam.? Both exams are Associate level and have same price of $250.
Find you one these questions in the current examination CCDA?
About question 6:
The following types of QoS tools are needed from end to end on the network to manage traffic and ensure voice quality:
•Traffic classification
Classification involves the marking of packets with a specific priority denoting a requirement for class of service (CoS) from the network. The point at which these packet markings are trusted or not trusted is considered the trust boundary. Trust is typically extended to voice devices (phones) and not to data devices (PCs).
•Queuing or scheduling
Interface queuing or scheduling involves assigning packets to one of several queues based on classification for expedited treatment throughout the network.
•Bandwidth provisioning
Provisioning involves accurately calculating the required bandwidth for all applications plus element overhead.
