Which SQL Server Certification should I take: 98-364, 70-461 or 70-761 ? – MSDN TSQL forum

February 18, 2017 3 comments

 
–> Question:

I just started learning SQL Server, and I want to get certified, I checked internet, but I got confused.

There is exam 98-364, 70-461, 70-761, and i want to get MCSA in SQL

could some one explain to me what should i do …
 

–> My Answer:

>> MCSA or Microsoft Certified Solutions Associate in SQL Server can be earned on following areas with respective exams:

– Database Development (761, 762)
– Database Administration (764, 765)
– Business Intelligence (767, 768)

>> Exam 98-364 is to get Microsoft Technology Associate (MTA) certification. It is the most basic exam that focuses just on basic SQL, and is for people new to technology, who need to validate their knowledge of fundamental concepts before moving on to more advanced certifications. This exam covers:

1. RDBMS, DBMS concepts and terms, like Normanization, PK, FK, etc.
2. Plain SQL querying knowledge, like DDL, DML, etc. and indexes.
3. Simple DBA stuff, like security, backup/restore, etc.

>> Exam 70-761 is also an advanced exam which is based upon SQL Server 2016, which is the latest version of SQL Server as of today. To earn MCSA you have to take 70-762 exam as well as mentioned above, check this link for MCSA SQL Server 2016: https://www.microsoft.com/en-in/learning/mcsa-sql-2016-certification.aspx

>> Exam 70-461 is also an advance level exam but now older based upon SQL Server 2012 or 2014. Check this link for MCSA SQL Server 2012/2014: https://www.microsoft.com/en-in/learning/mcsa-sql-certification.aspx

Please note: Exam 98-364 is not required here, and as mentioned above its just to make sure you have knowledge in working with basic SQL Querying.

SQL Server 2012 Certification Path

November 6, 2013 16 comments

It’s always good to give Certifications, it enhances your technical skills and prove your knowledge, and more over it looks good on your Resume!

Exactly last year I passed the “Querying Microsoft SQL Server 2012” (70-461) exam, and I blogged my experience [here]. Since then I get lot of hits on the post from all over the world. Then only I came to know that there are many people who want to pursue for this exam and other follow up exams in sequence.

People ask me about study materials, dumps (which I don’t recommend strongly). Few people have confusion to give which exam in what order. Some are not aware of the exams that lies in the Certification Path.
 

So, I have created a visual snapshot of all these exams for all SQL Server 2012 Certification exams at different levels:

SQL Server 2012 Certification Path

SQL Server 2012 Certification Path

So, you can start with any of the 3 exams at the bottom (first) level based upon your area of interest. A Dev can take 70-461, a DBA can start with 70-462, and a DataWarehouse Engineer can go with 70-463, and you can take them in any order.
 

1. Microsoft Certified Professional: As soon as you pass any one exam you are an MCP.

2. Microsoft Certified Solution Associate: After you are done with all three (70-461 + 70-462 + 70-463) you are an MCSA.

3. Microsoft Certified Solution Expert: After achieving MCSA, you can either go for MCSE in Data Platform (70-464 + 70-465) or Business Intelligence (70-466 + 70-467).

4. Microsoft Certified Solution Master: After achieving MCSA in Data Platform, you can go even further to MCSM by taking 70-468 & 70-469 exams.

– Exam 70-987: Not yet available
 

–> UPDATE:

– MCSE (DP: 464/465 and BI: 466/467) exams are updated with SQL 2014 topics.

– MCSA (461/462/463) exams will be having SQL 2012 content only.
