A company is planning the backup strategy for their virtual machine environment. They are considering migrating to an image based backup model. Where image-based backup would be processed in the environment?
On the virtual server
On a separate host
On the SAN
On the storage array
An organization with 25,000 employees has moved to a new building that contains a fully virtualized data center with a virtual desktop infrastructure (VDI) instituted for all employees. However, each morning between 9:00 am to 9:30, the help desk receives a large number of calls concerning slow performance and timeout issues. The IT department that the storage arrayâ€™s Fibre Channel drives is the bottleneck. They propose sold purchasing solid state disks (SSDs) to store the entire VDI environment. Unfortunately, their proposed is rejected because of the cost of the drives. Which array feature should the organization implement to reduce the quality of SSD that are required to service the high I/O bursts of their VCs environment?

Building robust private cloud services infrastructures By Brian Gautreau and Gong Wang Private clouds optimize utilization and management of IT resources to heighten availability. Microsoft Private Cloud
In February this year EMC introduced new certification track for Cloud Architects.
Cloud Architects deliver virtualization and cloud designs based on business strategies encompassing all key technical domains such as compute,storage, networking, applications, etc. EMC Proven Professional Cloud Architect (EMCCA) training and certification is designed to build required skill sets for experienced architects and consultants. The track has two levels. Virtualized Infrastructure (Specialist Level) and IT-as-a-Service (Expert Level).
Having pretty deep knowledge of virtualization (VMware Design certification VCAP-DCD) and IT service management (ITIL v3) I wanted to expand and formalize my education toward the cloud. As a holder of the basic EMC Information Storage Associate certification (EMC ISA) I was eligible to take the first step to the Specialist Level by taking the Virtualized Infrastructure Specialist Exam for Cloud Architects (">E20-018).
The curriculum describes the journey to the cloud (Virtualize -> Operationalize -> IT-as-a-Service) and concentrates on the second step of the journey; the design of cloud ready Virtual Data Center (VDC). Here is the list of course modules:
EMC offers a practice test on the education.emcm website. It is very similar to the actual exam test and by taking it you can see very well where you stand with the knowledge related to the exam. Without any prior study I scored 73% which would mean a pass on the actual exam, however I saw some gaps in my knowledge in the non technical areas which lead me to decision to study more. There are no reading materials available other then taking the recommended course. Fortunately there is Video Instructor Led Training (VILT) option available. It contains the video of an actual class (over 22 hours) plus PDFs with the study guides. I think reading the PDFs would be enough to pass the test, but I found that watching the actual class was very informative â€“ mainly the lab exercise parts which I really enjoyed where the instructor and students were weighting all the design options.
After the technological modules (2-6) come in my opinion the most interesting and enlightening topics 7 and 8: the Design and GRC (Governance, Risk and Compliance). The design methodology was very well described and explained on real life examples. The GRC concepts were quite new for me but still easy to understand. The module 9 â€“ Management corresponds to ITIL and module 10 introduces the third phase of the Journey to the cloud.
My only problem with the VILT was that it contains some kind of copy protection and I was not able to play it on my corporate Windows 7 laptop and had to run it in clean Windows XP Workstation virtual machine.
It took me about three weeks of night studying, mostly enjoyable, concluded with Pearson VUE examination.
As I already wrote the actual test itself is not particularly hard and is very similar to the practice test. Sixty multiple choice questions must be answered in two hour time limit (as non English native speaker I got 30 minute extension), but I was done in less than an hour. With the passing score of 83% I am now an EMC certified Cloud Architect.
There are reports of shortage of cloud architects. This certification helps to demonstrate the expertise of being one.
I was on EMC training last week. To be more specific, I was on â€śVirtualized Data Center and Cloud Infrastructureâ€ť training, and took the â€ś">E20-018 â€“ Virtualized Infrastructure Specialist for Cloud Architectsâ€ť afterwards.
First off, I passed the exam, which Iâ€™m happy about. Second, Iâ€™m still not sure how happy I am about the training and the exam itself.
When it comes to the training itself, we are talking about a week long, instructor led training. It covers several aspects of what would or could be considered elements of a virtualized data center, as well as cloud technologies.
You will start off with an overview of some of the definitions that make up cloud computing. A reference there is the definition of cloud, as it is defined by NIST. There is a reference the three service models of cloud computing, as well as the phases that you usually see when building a cloud infrastructure and the five key characteristics of a cloud delivery model.
You will also get an overview of the technologies that can be used to deliver a cloud like infrastructure. That includes stuff like different synchronization models, hypervisor types, link speeds (think of dark fibre as an example) and technologies used within a virtualized environment that range from a live migration, to the ability to offer services and service catalogs in a self service environment.
You also take a stab at things like governance, risk and compliance. You will get an idea of the things you can run in to when you create or even work with such an environment. You will references to things like the Sarbanesâ€“Oxley Act, and business driven frameworks and best practices like ITIL.
Mix that up with some labs that focus on giving you food for thought when designing a cloud like infrastructure (there is no hands on in the labs, just paper and teamwork), and it sounds like you have a pretty decent training.
Or does it?
I have two main problems with the course itself. For one, I think that itâ€™s based too much on the standards and concerns out of the US. I think that people absolutely need to be aware of things like the Sarbanesâ€“Oxley act, but I also feel that models and concerns should be highlighted for companies that are not bound by this act. Or at least tell these people why the rationale for these acts might be useful to implement, besides the â€śyou legally have toâ€ť way of explaining.
Donâ€™t get me wrong, you need to consider these kinds of things, especially in a cloud like environment where you more quickly are able to cross global and legal boundaries, but then also focus on things that you might encounter outside of the United States.
The second concern is much harder to address, since one might get the feeling that you are not being taught anything new. And I think this is the much bigger issue. In a sense, anyone who has been working on the â€ś* as a Serviceâ€ť environments will not really encounter anything new, and they might feel that EMC is just stating the obvious in their course. Techies that attend the training will probably leave with a feeling of â€śnot enough examples and hands on, too much fluffy stuffâ€ť.
I think that they are partially right. For me it was a large part of what I have already encountered more than once. On the other hand, itâ€™s good to see that people are working on standards, and the course itself brings together a lot of the things that you encounter, but might not knowingly consider. Itâ€™s â€śfood for thoughtâ€ť if you will. And as with all such classes, you get a chance to exchange ideas and perspectives with your classmates, and that might be the most valuable thing about this class, especially with a topic that is harder to grasp (from an actual technology usedwhere do i start standpoint).
Read carefully! The biggest piece of advice I can give you, since sometimes the wording of the questions is just plain odd. Also, make sure you have an idea of the technology used in data centers, and virtualization across different tiers. Examples of the last one could be things like storage and network virtualization.
Spend some time on getting to know what governance, risk and compliance is all about. Have some sort of insight of what are the driving factors behind GRC.
The certification can be achieved, even without the training, but I feel the way some questions are asked is perhaps the biggest issue you can face in passing the exam if you already have some experience in designing or working in cloud like environments.
And let me wish you some good luck if you attempt to take he certification! One important note is that the EMC E20-001 is a mandatory prerequisite before attempting the certification, so make sure that you have that one if you want to be an EMC certified cloud architect.
