Breaking the Duck

It’s been over 18 months since I last sat an IT Pro exam of some description and frankly that was far, far too long. I should really have taken my TOGAF 9 exams last year as a minimum as the Architecting the Enterprise course I attended in London in May included the vouchers for the combined TOGAF exam, but it just never happened.

Today though, I finally broke the duck on my exam sitting and took my VMware Certified Professional 5 Datacenter Virtualization (VCP5-DV) exam and passed it. Maximum score for the exam is 500 and the minimum passing score is 300. I scored 380 which works out to be just shy of 80%. I wasn’t thrilled with the result, but I was happy to pass it first time round.

I got lots of questions on VMware FT which is probably my weakest area of the product after spending a lot of time researching iSCSI and NFS to square up on my existing Fibre Channel knowledge to cover all the storage topics. Although I’ve now passed the exam, I’m going to continue my research to try and brush up more of Fault Tolerance.

Next up? Well, my Cisco CCENT qualification expires in April this year, so I’ve got three months to pass my ICND2 exam to gain my CCNA or I lose the earlier CCENT and have to sit both exams again. Luckily, my networking knowledge has grown a lot since the first time I sat ICND2 and failed it about two and a half years ago, so I’m confident with some new research and studying into serial connections, IPv6 and a few other bits, I will be able to pass that exam.

Onwards and upwards…..

Configuring VMware Data Protection Appliance (VDP)

Yesterday, I had the chance to stand up a VMware Data Protection (VDP) appliance virtual machine. This is the replacement for VDR in vSphere 5.0 and upwards and is based on the EMC Avamar product.

When configuring the VDP appliance for the first time using the https://hostname:9543/vdp-configure URL, you are asked for credentials to connect to vCenter. The interface tells you that this is used to register with vCenter, but what it doesn’t tell you is that this account is actually then used for on-going access to vCenter and creating and deleting the snapshots on the VMs it is backing up. Therefore, make sure you use a service account and not your own account.

There is also a requirement for this account to be directly permissioned in vCenter and not via a nested group membership, so make sure you do this before attempting the registration.

VMware vSphere 4.1 and VCP Web Links

Having just finished the course for vSphere 4.1 today, it’s going to be all hands on deck revising this stuff for VCP for the next week or so. Here is a list of useful links for vShpere and ESX/ESXi related knowledge which will liekyl help others along with myself in my quest to obtain VCP.

I will be updating this list on an on-going basis with all of the resources I come across.

Lastly, I cannot and will not vouch for any of these sites. These are merely just sites I have found to be useful for me.
