Thanks guys, together we can crack not only the written but the practical exam too.

Has anyone taken the practical exam before?

[offer] CCDE Written V3 Questions

[keje]

I will share all i ask is that we fix the 20+ incorrect answers and reshare back to the group

[cciede11sure]

@keje Pls let me know how can i help to fix all the 20 incorrect ans....

[CiscoCisco]

most of them solved.  Anyone interested for CCDE LAB study group PM me

CONNECTIVITY / CAPEX / OPEX /  ANNUAL / INSTALLATION FEE / TERM
DWDM over dark fiber /  $200,000 / $100,000 / $30,000 / 12 months
CWDM over dark fiber / $150,000 / $100,000 / $25,000 / 18 months
MPLS wire only / $50,000 / $180,000 / $5,000 / 12 months
Metro Ethernet / $65,000 / $100,000 / $5,000 / 36 months

Refer to the table A customer investigates connectivity opt for a DCI between two production data centers to aid a large-scale migration project. The migration is estimated to take 20 months to complete but might extend an extern 10 months if issues arise. All connectivity options meet the requirements to migrate workloads. Which transport technology provides the best ROI based-on cost and flexibility?
A. Metro Ethernet
B. MPLS
C. DWDM over dark fiber
D. CWDM over dark fiber

Lets discuss which one is best ans and why ? 
My vote is with Option A because its lest expensive in simple math. but i may b missing the trick as CCDE do not test our math skills.

The key here should be the large-scale migration.

And because of nature of the migration (Datacenter), most likelly is a very-high speed and not all in one  shot

So, will be an L2. Here we can exclude MPLS.

They didn't mention anything about DC's location, so in this situation, would exclude CWDM (as it is for metro area only)
So, we have DWDM and MetroE

 

So, in this question the answer will be really  MetroE.

If they would say is more than 10 Gbps, then would be DWDM

 

This is just my opinion 🙂

I would have to agree with you also. nothing points to cw or dw.

There are other 2 questions with similar comparission.

Those are more tricky.

The one with QoS, means the connectivity should be pure L2 and only DWDM and CWDM do this. Metro Ethernet is an VPLS (not pure L2). So, the cost is really between these 2 and is CWDM

Another one, is with the capability to increase the bandwidth, and only DWDM can oversubscrive if I recall corectly.

@raptoriksTrue metro-e is vpls but you can trunk additional vlans( for more networks to communicate) but not expand the bandwidth on that type. Which the 2 options are cw and dw then it comes to how many channels and cost for hardware

[cciede11sure]

Interesting...Large scale mean - high speed link which can exclude CDWM. because CDWM best option are 10 Gbps and 16 Gbps whereas DWDM can go up 400 Gbps...

Here is another one with QoS trick

CONNECTIVITY / CAPEX / OPEX /  ANNUAL / INSTALLATION FEE / TERM
DWDM over dark fiber /  $200,000 / $100,000 / $30,000 / 12 months
CWDM over dark fiber / $150,000 / $100,000 / $25,000 / 18 months
MPLS wire only / $50,000 / $80,000 / $5,000 / 12 months
Metro Ethernet / $45,000 / $100,000 / $5,000 / 36 months

Refer to the table. A customer investigates connectivity options for a DCI between two production data centers to aid a large-scale migration project. The solution must provide a single 10G connection between locations and be able to run its own varying QoS profiles without service provider interaction based on the migration stages. All connectivity methods are at 10 Gbps. Which transport technology costs the least of the connectivity is required for just one year?

A. Metro Ethernet
B. MPLS
C. DWDM over dark fiber
D. CWDM over dark fiber

In this i can safely say CWDM because of two reason...QOS and second 10Gb is perfect speed offered by CDWM with less cost.

Another One

 

CONNECTIVITY / CAPEX / OPEX /  ANNUAL / INSTALLATION FEE / TERM
DWDM over dark fiber /  $250,000 / $100,000 / $30,000 / 60 months
CWDM over dark fiber / $150,000 / $100,000 / $25,000 / 50 months
MPLS wire only / $50,000 / $150,000 / $75,000 / 12 months
Metro Ethernet / $45,000 / $120,000 / $5,000 / 36 months

Refer to the table. A customer investigates connectivity options for a DCI between two production data centers. The solution must provide dual 10G connections between locations with no single points of failure for Day 1 operations it must also include an option to scale for up to 20 resilient connections in the second year to accommodate isolated SAN over IP and isolated, dedicated replication IP circuits, All connectivity methods are duplex 10 Gbps Which transport technology costs the least over two years, in this scenario?
A. Metro Ethernet
B. DWDM
C. MPLS
D. CWDM

Simply go with B as only DWDM can scale up to the requirement.

Hi all,

Can anyone share the dumps please?

 

Thanks in advance!

 

[bruh82]

Guys

 

any dump that is available?

[zully]

I prepared with 100 Q with vce file and tomorrow I am thinking to take exam ? is it safe?

[zully]

Please share the correct answer of the attached image drag and drop, CCDE.

Hi Zully,  How many percent of correct answer on this dump ? and How many new question?

 Thank you to share status of your exam.

is it the same file that was shared by keje ? or with some new changes?Pls confirm it

[coolftd]

not sure why the file 3-16 shows as 2-28 when you uploaded to vce player , any idea ?

[coolftd]

Yeah, I thought the same ,anyway thanks man

he forgot to change title of that vce.  Anyway find VCE or PDF named "400-007_unlocked_3.16" or "400-007_unlocked_3.16.fixed" to use; Do NOT use PassLeader stuff !!!
