NCDA NS0-155 NetApp – Introduction

Few words about NS0-155 NetApp Certified 7-Mode Data Administrator

Recently I passed NS0-155 exam and I can be recognized as NetApp Certified 7-Mode Data Administrator. I would like to share with some fundamentals that could help you with decision whether is worth to do this exam or not.

I have chosen 7-Mode exam because I am learning this technology for more than 6 months and I was engaged in a quite big transition so NetApp in 7-Mode has become my main interest. Willy-nilly I am receiving big amount of experience and knowledge thanks to nice environment that I have pleasure to manage, so it became natural for me to prove my expertise with some piece of paper.

Next thing from carieer perspective is that the 7-Mode is still on the page and it will be like that for at least few years. Official support will finish at 2019. And the last thing that should convince you to take a try with this exam is just a pure knowledge. For many people certification is a great opportunity for opening a book and start learning. And I don’t believe that even a great admin has knowledge about everything in a subject, therefore taking a certification is a great way to refresh memory and keep our brain in a good condition.

What do we know about NS0-155?

Unfortunately Netapp does not provide much information about topics related to exam. From their webpages we can find only general informations.


NS0-155 will include Data ONTAP administration, data protection, high availability and large aggregates.

Recommended trainings:

- Data ONTAP 7-Mode Fundamentals (WBT)

Exam details:

The NS0-155 exam includes approximately 60 test questions and requires approximately 1-1/2 hours to complete.

Let’s look at course topics from 7-Mode Administration:

- The Data ONTAP Storage environment
- WAFL Simplified
- Basic Administration
- Physical Storage
- Logical Storage
- Administration Security
- Networking
- Network File System (NFS)
- Common Internet File System (CIFS)
- NAS Management
- Storage Area Networks (SAN)
- Snapshot Copies
- Space Management
- High Availability
- Virtualization Solutions

The Accelerated NCDA Boot Camp Data ONTAP 7-Mode course is more focused on skills coming with protocol administration (NFS/CIFS/FCP/iSCSI) and replication methods (Snapvault, Snapmirror, OSSV). There are not much about WAFL, physical/logical layer etc.

Basically it seems to be much, but this exam does not require from us expert knowledge. You just need to feel comfortable in above areas and explain major concepts. You should have some practice on evironment because some questions can be detailed. Also it’s good to know additionals features related to 7-Mode administration.
