Brocade Certified vRouter Engineer Exam 170-010

As I mentioned in a previous blog post, Brocade is offering free courses and exams.

Even though I’m not actually working in networking, I decided to brush up my networking knowledge by taking the 170-010 Brocade Certified vRouter Engineer Exam. I haven’t really done much with networking and CLI configuration in the last 7 years, but I still know the concepts from school where we did CCNA, CCNP, CCDA, CCDP. It took me about 2 days to study and I passed with 76% (passing score = 62%). In hindsight I should have played around a bit more in the vRouter itself :)

The exam wasn’t that hard, but a little knowledge about networking is expected, because the information provided by Brocade does not cover everything (or I missed something). For people who want to take the exam, you can use the resources described below. Make sure you’re very familiar with routing, OSPF, NAT and firewalling.

Free – Brocade Network Function Virtualization (NFV) course and exam

A student of mine informed me that Brocade is providing a free course and exam again. This time it is for Brocade Network Function Virtualization”
A while ago they also provided a similar offer for “Brocade Ethernet Fabric” which is also still valid apparently.

Take advantage of these offers if they are useful to you :)

Book review : Cloud Computing Concepts, Technology & Architecture

CCCTA_cover

Title: Cloud Computing Concepts, Technology & Architecture
Number of pages: 
528
ISBN: 9780133387520
Released
May 2013

My opinion:

The book is well written, is vendor neutral, covers both business and IT aspects and contains many great diagrams. It also has a lot of useful references to external resources.
What I disliked, is that because of the vendor neutral approach some aspects are relatable enough (especially for people that don’t have a lot of working experience). I feel the book would have benefitted by providing more real-life examples of products or services.

The book is a good start for experienced people and will especially come in handy as a reference when getting involved in cloud computing projects. It will help understand vendor specific products and services better.

I would recommend people that are new to cloud computing (or that have very limited working experience) to first read a cloud essentials book like the one from Sybex before reading this book though.

To take a look at the book and its content, you can visit the book’s companion website: http://servicetechbooks.com/cloud

My ‘ITIL Foundation’ certification experience.

For quite some time, I was planning to get certified for the latest version of ITIL Foundation since I was “only” ITIL v2 certified. A couple of years ago I bought the v3 book and started reading, but for some reason I found it very boring and just couldn’t motivate myself enough to complete the book and get certified.

In the next couple of years I mainly focused on other certifications and ignored ITIL v3 until last week. I took my old book and started reading again. To my surprise everything seemed to be far more logical than back then and I went through the book very easily. Maybe it’s because of the added experience or maybe I just wasn’t motivated enough back then, but I even liked the content in the book.

After reading the book I tried some sample exams and these went great even though apparently my book was outdated since the ITIL Foundation book had been updated in 2011. Just to be sure I bought a new version of the book, but in my opinion there weren’t any big changes.

The exam itself was also very easy. So now I’m going back to focusing on cloud computing again :)

Book review : Cloud Essentials – CompTIA Authorized Courseware for Exam CLO-001

9781118408735 cover.indd

Introduction

For those who haven’t read my previous blog posts, here’s a short summary. About 1,5 – 2 years ago I decided that I wanted to know more about cloud computing and get certified as well. I used freely available resources to attain these certifications:

In short, my conclusion was that the quality of the freely available resources were not sufficient. ITpreneurs were kind enough to provide me with access to their e-learning course and Train Signal (now Pluralsight) provided me with their video training. Reviews for both can be found here:

Even though both resources are good, I personally prefer a book over eLearning and video training. As such I picked up a copy of “Cloud Essentials : CompTIA Authorized Courseware for Exam CLO-001

Review

Number of pages: 268
ISBN: 978-1-118-40873-5
Released
: June 2013

My opinion:

The book is well written and knows to provide a very good basis of cloud computing both technical and non-technical. Even though the number of pages is limited, the most important aspects are covered in my opinion, which should be enough to provide insight and to pass the Exin and Comptia cloud exams.

What I disliked are some of the questions at the end of the book, because they are sometimes a bit strange. But as far as I can remember, this was also the case in the official exams … so better get used to it if you are going to get certified.

All in all, this is a very good book to get started with cloud computing.

PowerShell – Book review of : Windows PowerShell Best Practices

Windows PowerShell Best Practices

Last week I completed PowerShell Deep Dives which got me excited again to read more about PowerShell. As such, I continued reading the next book on my reading list: Windows PowerShell Best Practices by Microsoft Scripting Guy Ed Wilson.

The book was released late January 2014 and is the most recent book about PowerShell that has been released to my knowledge. This means it includes PowerShell 4.0, Desired State Configuration DSC and references to Windows 8.1 and Windows Server 2012 R2.

In my opinion the book was very well written and contains a good mix of theory, sample scripts and “notes from the field” from many PowerShell specialists. The sample scripts are available for download at Technet Script Center.

The best practices that are described in the book are very recognizable and I had already adopted many of them based on the many great blog posts by the community. In the book they are all bundled and well explained including examples. Where the book really shines though in my opinion is that it describes how PowerShell is used in real-life, how it relates to many other processes within a company and what you need to consider.

I think this book is a must-have for anyone working with PowerShell. For those starting with PowerShell, I recommend first reading the books “Learn Windows PowerShell In A Month Of Lunches” and “Learn PowerShell Toolmaking In A Month Of Lunches” and then read this book.

PowerShell – Book review of : PowerShell Deep Dives

PowerShell_Deep_Dives

I’ve had the book PowerShell Deep Dives laying around since August 2013. I had read some parts of it because I follow many of the great PowerShell community members that contributed to it. But I hadn’t gotten to reading it completely yet until now.

The title of the book includes “deep dives” implies very deep technical content and I can assure you, this type of content is present in the book. some of the stuff I still need to wrap my head around to understand properly. On the other hand, other parts of the book are more simplistic which you might not expect from a deep dives book.

The book covers a very broad number of topics and technologies. What I liked is that the articles were written by professionals and community members that are specialized in or are very knowledgeable about this specific topic/technology.

As a result of having the broad number of topics and technologies, not all parts of the book might be relevant to you (especially as a deep dive). I found myself skimming over some parts later in the book since it is very unlikely it is or will become useful for me. This will differ from person to person though, so take a good look at the topics being covered in the table at the end of the article.

All in all it was a good read and I think I’ll use the book mainly as a reference for those times that I need the deep dive insights. The book can be ordered from by example Manning.com and all royalties go to charity: Save the Children

Introduction to PowerShell – Also relevant for NON Microsoft administrators

Today I had the privilege that many colleagues of mine from Open Line decided to sacrifice their free time and attend my session: “Introduction to PowerShell – Also relevant for NON Microsoft administrators”

The goal of this session was to:

  • Inform people of the advantages of scripting/automation in general.
  • Inform people of the advantages of PowerShell over CLIs and other scripting languages.
  • Inform people that PowerShell is not just for Microsoft administrators.
  • Teach people about the PowerShell basics.
  • Inform people about the many possibilities with PowerShell.
  • Provide people with a lot of practical resources to increase their knowledge and skill.

I really enjoyed the session and got a lot of interactivity and positive feedback. Next up is a follow-up session which will be more of a workshop style.

I’ve uploaded the presentation in PowerPoint and PDF format here:
https://bjornhouben-web.sharepoint.com/Lists/Files/DispForm.aspx?ID=22

Please share this so that others can benefit from it as well.

Notes:

  • I’ve included many useful resources as notes in the PowerPoint presentation, which makes the presentation also interesting to people who are not PowerShell beginners.
  • Also if anyone has suggestions to make the presentation better, please let me know.

OneDrive / SkyDrive – fix for onedrive sync engine host stopped working

As an IT professional I tend to work on multiple systems (tablets, laptops, desktops) and I use OneDrive (SkyDrive) extensively to always have access to the latest versions of my documents.

I love OneDrive, but today when I wanted to continue working on my desktop I got an error : “onedrive sync engine host stopped working”. So first thing I tried was just restarting OneDrive, which didn’t work. Then I figured … ah well let’s just reboot and see what happens.

When this also didn’t work I looked online and saw I wasn’t the only one experiencing this. I also came across the OneDrive Troubleshooter tool. After I ran this, followed the instructions and waited about 5-10 minutes, it worked properly again.

I hope this helps you to resolve similar issues.

Notes:

  • In processes the process shows as OneDrive Sync Engine Host , but the process is still SkyDrive.exe
  • In the application log, an event 1000 was generated with the following information:Faulting application name: skydrive.exe, version: 6.3.9600.17055, time stamp: 0x53291a62
    Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000
    Exception code: 0x00000000
    Fault offset: 0x0000000000000000
    Faulting process id: 0x1050
    Faulting application start time: 0x01cf78c9a55d1428
    Faulting application path: C:\Windows\System32\skydrive.exe
    Faulting module path: unknown
