Remote VCAP-DCV Deploy exam experience

Hi everyone! On September 4th I took the VCAP-DCV Deploy 2022 exam and passed it so this post will be focused on my experience of taking it remotely through Pearson Vue platform.

Long time ago, I wrote a post about preparing for a VMware exam and a couple of things have changed since January 2021 related to deploy exams.

First and foremost, by the time I wrote that post, deploy exams were not allowed to be taken remotely but now they are. The process of scheduling it is exactly the same as for any other exam so nothing change on that side.

To give more detail to the ones that don’t know how a VCAP Deploy exam is, you are given some questions (the amount depend on the exam) with multiples tasks to do (e.g.: create a cluster and then configure HA, DRS, DRS rules, syslog, etc.). The type of questions will be related to the blueprint of the exam (read the post mentioned earlier to understand where to get the blueprints). The environment you are given is exactly as a HOL Labs experience (when taking it on site) with the difference that is exam is embedded into the Pearson Vue app (when taking it remotely). On each sides you will have a console and a manual tab that can be pined or floating to allow resizing. You are allowed to have 1 screen only so having a higher resolution would be you best ally for this type of exams.

Regarding the exam itself, the overall experience was really good. I was using QHD resolution and the exam environment adapted automatically to my resolution (Note: don’t know if this is always done automatically as I only took this exam remotely by the time of writing). This was extremely important during the exam because there was no need to spend time adjusting the browser zoom.

Some recommendations about the exam:

  • Pay attention to the instructions given, if it says not to reboot the host, DO NOT REBOOT IT. Read the complete instructions first and then go into what you are being requested.
  • Don’t wait for tasks to end if it’s going to take long, for example: rebooting a virtual machine, send the reboot action and come back later.
  • If you have some buttons on the either side and they are hidden because of the manual and/or consoles panel, pin it to the other side and keep going with the exam. Don’t lose time trying to zoom in/out the browser to make that button appear, it might never happen if it to close to the edge of the screen.
  • If you don’t know how to do a question, skip it and come back later when finished with the ones that you know, time management is very important.
  • Use notepad to make some notes about tasks that you have to finish yet if your memory is not good enough.
  • Avoid using the console tab unless you are sure that you need them, it takes time to change between them and you might lose some valuable time there, especially if you are doubting which one you need and clicking between multiple of them. Try to access that resource through the network first and if you can’t then go to the console tab.
  • Be confident on how to use VMware documentation and KB’s, some resources are being given to you to help but you should know where to look for the steps.

They exam environment had some struggling parts too. When I started to use keyboard shortcuts my right click “got stuck”, not physically, but digitally. I was not able to click between tabs or access any other shortcut on the desktop or taskbar. What saved me was to know a couple more keyboard shortcuts to bypass that click restriction in some areas, using ALT+TAB to reach the desktop and then hit the first character of the shortcut that I was trying to access (e.g.: putty), so my recommendation is to be confident with this too before taking the exam. I temporary fixed it going back and forth between consoles, but it got stuck again later on.

Going into the results, they are not shown automatically like any other exam (VCP or VCAP Design). It takes between 24-48 hours to arrive. Mine took less than 24 hours, including the VMware certification and badges (VCAP and VCIX) so great timing.

VMware Cloud Director Upgrade History

Hi everyone and welcome to a very short post. This post is going to cover something that I was asked today. The question I have received was “Do you know the upgrade history of our VMware Cloud Director enviroment?”

You can find the upgrade steps in the following link

Note: The following steps apply only for the appliance deployment.

To troubleshoot the upgrade, there is a file you can check to monitor the upgrade process.


In the file you can find the following information that shows from which version you are upgrading and the destination version.

Said that, I have created a single liner

more /opt/vmware/var/log/vami/updatecli.log | grep "to version"

The result of that one liner is the complete upgrade history. Keep in mind that if you delete this file or you redeploy a cell for any reason, that information won’t be available.

I hope you enjoyed this rush post.

If your are interested in a specific topic, let me know in the comments section below and I’ll be happy to write a new post about it.

Be sociable, share it!

Troubleshooting VMare Cloud Director Log Bundle generation

I know it’s been a while since my last post, so I’m very happy to be again on the road.

Last week I had some issues in a VMware Cloud Director enviroment that ended up opening a support request with VMware. During the case development, the support team requested me to create a log bundle, but I wasn’t even able to generate it, so that’s where this story begins. Please note that the modifications I’ve done might not be supported by VMware.

For those who are not familiar on how to generate a VCD log bundle, here are the steps

The error that I was having was the following

General message showing the general error message
Some Cells where showing a FAIL status. In this image just one but most of them where showing the same status

The first step to troubleshoot this situation was to identify which cells were the ones with a FAIL status. The CELLID can be obtained with the following command

 more /opt/vmware/vcloud-director/etc/ | grep cell.uuid

To troubleshoot the bundle generation process there are two log files located under /opt/vmware/vcloud-director/logs


This first log file shows if the cell detects the marker file that indicates the cell to start generating a lod bundle. On a regular situation it should look like the following

This means that the cell has detected a marker file
This is the marker file located in

From that side everything was looking perfect, so I went into the other file to understand what was happening.

Normal log file situation. Started and completed

Analyzing the logs I found two different errors. The first one, that a log collection process was still running. The way I managed to fix this, was to shutdown the cell services and start them again.

Abnormal situation, a log collection process was still running

The second error was just a timeout. I wondered where that timeout could be configured to extend it.

Abnoral situation. Timeout reached and marker has been removed

After I realized about that, I started digging deeper into the support bundle generation script.


I’m not going to cover the complete script because it’s not the central topic of the post. In that file I found the some variables that pointed me into the multi-cell-log collection script, so it was time to check that file also.

vmware-vcd-support script variables

I opened the file with the following command and founded that there was a timeout variable that I could modify.

 vi ${VCLOUD_HOME}/bin/vmware-vcd-multi-cell-log-collector
Timeout variable without modifications

So I decided to modify that value and try again. It’s not a value that will wait until it expires, it’s just a maximum timeout. If the cell bundle generation ends earlier, the script will continue.

Modified timeout value

After modifying that timeout everything was working again so I returned to the vmware-vcd-log-publisher.log to analyze how much time was taking, just out of curiosity. It was taking between 8-9 minutes, a little more than the default.

I ended up doing a cleanup of old logs, and the process was smooth again in less than 7 minutes.

There is another reason why this process might fail and its detailed on this kb

Flash Player and VMware Management Consoles – What to do

Hi! Thanks for joining me back at this new post. We will be talking about what to do if you came up with the Flash Player End of Life and you are not ready for upgrading your infrastructure. If you are ready for upgrade, I have wrote down some tips on how to check VMware products upgrade path and compatibility matrix.

Most of you might noticed that when accesing some VMware mangement consoles (eg: vCenter, Horizon View, etc) that uses Flash, an icon like the one below will be shown because of Flash EOL on January 12, 2021

Internet Explorer:

Google Chrome:

What can we do to address this?

  • First and foremost, do not panic, it only affects your management console but not your virtual machines or services like Horizon. Everything will keep on working as it was before.

I have tested it on Internet Explorer and it worked like a charm.

Original file:

Modified file:

Gained acces again, Woho!

  • If you are not on a critical situation, plan you upgrade, check the product interoperability matrix and the upgrade path of each product you have on the same situation, or products related to the ones that you will need to upgrade.

The product interoperatibility matrix will tell you if a product is compatible with another one (eg: vCenter with Horizon, vCenter with NSX, etc).

The upgrade path will tell you which upgrades from version to version are supported, so you can plan if multiple upgrades are required to reach the desired state. Let’s suppose going from Horizon 6.2.9 to Horizon 8 (2012) you will need an intermediate upgrade to Horizon 7.13, and then Horizon 8 (2012)

Product Interoperatibility Matrix:

Upgrade Path:

How to use Product Interoperatibilit Matrix? It’s very easy. Just select at least two products (you can select more than one at “2. Add Platform/Solution”) and It will display if they are compatible or not.

If the products selected have a green check, good to go, plan the upgrade (check the upgrade path section too, it’s very important) and also plan a rollback just in case is needed (eg: backup, snapshots, etc). If you got into a failure open a support case with VMware
*You must have your support up to date to have support. Contact VMware or your Partner to renew it.

If a red line is displayed, do not try that combination of versions, its incompatible and the product might work in an unexpected and unsupported way.

If a grey line is displayed, they are not supported. You will have to find a combination that might work for you and the corresponding upgrade path if the products are linked in some way. A situation like this might be upgrading vCenter from 6.5 U2 to 7.0 U1 and NSX-V from 6.3.7 to 6.4.9. You will need to upgrade first NSX-V from 6.3.7 to 6.4.6, then vCenter from 6.5 U2 to 6.7 U3 (you can not jump directly to 7.0 U1 because NSX-V would not support it based on product interoperatibility matrix), then NSX-V from 6.4.6 to 6.4.9 and again vCentr from 6.7 U3 to 7.0 U1.

If you want me to write a more detailed post on how to plan a VMware upgrade just type in the comments section below.

Thanks for reading. See you on the next post =)

How to prepare a VMware Exam?

Hi everyone! This post will be focused on VMware exams how to check which ones are available, requirements, how to prepare and some other tips.

The following tips are the ones that were useful for me and I would appreciate if you can share your own experience in the comments section below.

You can go to this link to check all available exams

By the time of this post, there are 6 tracks alligned with different VMware products. Some of them are going to have certification and digital badges. There are 4 certification levels, VCTA, VCP, VCAP and VCDX. Keep in mind not all tracks include all the levels VCTA, VCP, VCAP and VCDX.

Once you’ve decided the track that you’re going to be evaluated on, you have to click on the selected track and then on the specific exam.

Once you click on the selected exam, you will be redirected to a web page where you will see the exam details like duration, number of questions, passing score and format.

Now that we know a few basics about the exams, we will step forward to the following tips.

Before the exam:

  • Check the exam code and download the blueprint from the exams detail webpage.
  • Check the blueprint sections and objectives. This is everything that you will need to cover before the exam. Start studying the objectives where you are sure that it’s a weak or unknown spot. That will give you more confidence that you will be ready because on strong spots you might need less time to study and if the exam date comes up close, you can give it your best shot.
  • To prepare each objective/section you will have a list of reference documents to read and learn.
  • Check the blueprint if there are any recommended courses because I have found some of them to be extremely useful (eg: VMware vSAN: Production Operations [V6.7])

During the exam:

  • If you do not know the answer, mark the question and keep going. At the end, you will have the oportunity to review the marked questions. Do not rush to skip it, but do not take too much time to decide, you have a limited time to do the exam.
  • If you are taking a VCAP Deploy exam, check on the time frequently, time is your number one enemy. Think if the task is a long one (eg: feature enablement, component deployment, etc) and keep going with the next task after having the task running. Do not lose time waiting for it to finish.
  • For all exams, if time has ended, the exam will be saved. I thinks that you will not lose points for the questions answered (I suppose, not sure 100%).

After the exam:

  • If you passed it, congratulate yourself and start preparing for the next one.
  • If you took a VCAP Deploy exam, relax because it might take 1 or 2 weeks to have the results because they are not shown immediately when finished. You will receive an email like the following.
  • If you have failed it, check the score report so you can make focus at weak spots for the next time. It’s not the end of the world, a failure is an opportunity to learn more.

Veeam Notifications Error

Hi. I want to share with you an error that today I came up with. Some of our customers started to experience and error with Veeam Backup & Replication notifications. I have made a procedure to fix it my way, there is no Veeam KB or support ticket related to it, so use it at your own risk. Please make a backup of the database before continuing.

When a job finished it was displaying this message:

When you open the general options to check the notifications section, a message like this is displayed:

To do the following steps you will need a SQL Management Studio to access the SQL Server hosting the DB and a user with privileges to access it.

Based on the message I started to check tables in the database that might contain the information that was not parsed ok and I reached a table called Options so I made a select to the table to check if it was storing information that might need to be modified to fix the issue.

FROM [VEEAMDB].[dbo].[Options]

/** Modify the VEEAMDB database name to you enviroment database **/

Once I made the select I discovered that it was an entry with the email_notification configuration:

If you do not remember the configuration you had, you can click the value and gather the info in an XML format.

After making a backup of the information, I cleaned up the value with the following query:

  update [VEEAMDB].[dbo].[Options]
  set value = ''
  where name ='email_notification'

After executing the query (no reboot needed) I was able to open the general settings and configure the notifications options again based on this Veeam procedure

I think that this “bug” might be related to something like this Veeam KB on datetime format when installing or upgrading.

I hope it helps you and any recommendation or question, please comment below.

Speedup host readiness for VMware Cloud Foundation (VCF)

Hi, and welcome to my first post.

In the last couple of months I have doing lots of POCs (Proof Of Concepts) about VMware Cloud Foundation (VCF onwards) and every time I reinstalled the hosts to show the Bring Up process (that will be covered in another post) I was spending a lot of time, approximately 10 minutes per host between login, page navigation and configuration, to get a host ready to be used by the Cloud Builder VM.

Because of that, I have developed a script to speedup the process and minimizing the human error of having a configuration mismatchs between hosts.

The Cloud Builber VM requirements for the ESXi are the following:

Note: They might be different depending on the version of VCF you are using, at least for 3.9.1, 4.0, 4.1 the above image is the same.

If any of the above requirements are not met, the Cloud Builder VM will display a warning message that can be dismissed, but the process will fail and you will have to start over.

The script will address only the following ones:

  • VM Network portgroup must match the Management Network VLAN ID
  • TSM-SSH must be turned on and configured to Start and Stop with Host
  • NTP must be configured, running and configured to Start and Stop with Host
  • Check if the vSwitch0 has more than one nic configured (just inform, does not modify vSwitch nic assingment)

How to run it? Grab the latest version of Power CLI from VMware{code}, copy the content of the script into a file and save it with a .ps1 extension, open powershell as an administrator and run the .ps1 file. The script itself will modify some PowerShell configurations to run.

The script run will look something like the following.

  • Errors that must be fixed are displayed on red
  • Warnings might be ignored and are displayed on yellow

So now that we know which are the requirements and how to run it lets dig in into the code. Feel free to copy, modify and share it. If you find any bug or recommendation please post it in the comments section.

Ps! While this post is out, I’m working on a new version to make it even easier. So be ready for more VCF scripts!

If it fails just run $error on powershell and send me the output to fix it!
