Time for some changes in the AWS <\/a>suite of 12 certifications. Here is a quick recap from the previous blog<\/a>. There are two changes for existing certification and a new certification that is coming out soon. <\/p>\n\n\n\n

    \n
  1. AWS Certified Solutions Architect \u2013 Associate has a new version SAA-C02. Check out our blog<\/a> on the changes breakdown. Coming March 23, 2020. <\/li>\n\n\n\n
  2. AWS Certified Data Analytics – Specialty (formerly AWS Certified Big Data – Specialty) has a new version DAS-C01. Coming April 13, 2020. <\/li>\n\n\n\n
  3. AWS Certified Database \u2013 Specialty is a new exam. Coming April 6, 2020.<\/li>\n<\/ol>\n\n\n\n

    In this blog, we will stress on the pivot from AWS Certified Big Data – Specialty (BDS-C00) to AWS Certified Data Analytics – Specialty (DAS-C01)<\/strong> examination. The beta exam is done with and many people have received their score. This means it’s time for the real deal. <\/p>\n\n\n\n

    The registration for this exam began on March 17, 2020 and the first day to take this exam is April 13, 2020<\/strong>. This means the last day to take BDS-C00 is April 12, 2020<\/s>. AWS has changed the last day to take BDS to June 30, 2020. There are already a lot of materials and practice tests<\/a> available online for the older exam.<\/p>\n\n\n\n

    Changes to the exam content and Recommended AWS Knowledge<\/h2>\n\n\n\n
      \n
    1. Still a pass or fail exam<\/li>\n\n\n\n
    2. There are still multiple choice and multiple response questions<\/li>\n\n\n\n
    3. Unanswered questions are scored as incorrect; there is no penalty for guessing<\/li>\n\n\n\n
    4. Some questions are unscored; these do not affect your overall score and are there gather statistical information<\/li>\n\n\n\n
    5. Results for the examination are reported as a score from 100-1,000, with a minimum passing score of 750 and there is no requirement to pass the individual section, only the overall examination. (NEW<\/strong>)<\/li>\n\n\n\n
    6. Apart from the 2 years of hands-on experience, AWS <\/a>now recommends a minimum of 5 years of experience with common data analytics technologies for this certification<\/strong>. (NEW)<\/strong><\/li>\n<\/ol>\n\n\n\n

      As the exam guide suggests, this certification is intended\nfor individuals who perform in a data analytics-focused role. I believe AWS has\nmade the right move by making Big Data to be a part of Data Analytics certification\nand not be a certification by itself. This makes sense, considering each AWS analytic\nservice is purpose-built for a wide range of analytics use cases such as\ninteractive analysis, big data processing using Apache Spark and Hadoop, data\nwarehousing, real-time analytics, operational analytics, dashboards, and\nvisualizations.<\/p>\n\n\n\n

      Side by side changes to the topics covered for the exam<\/h2>\n\n\n\n

      Let us first draw side by side comparison of the changes in\nthe exam format: <\/p>\n\n\n\n

      AWS Certified Big Data \u2013 Specialty (BDS-C00)<\/strong>
      <OLD EXAM><\/strong> <\/th>      		AWS Certified Data Analytic – Specialty (DAS-C01)<\/strong>

      Summary of the differences:<\/p>\n\n\n\n

      Domain<\/th>Big Data
      (Old Exam)<\/th>      		Data Analytics<\/strong>
      (New Exam)<\/th>      		Difference<\/strong><\/th><\/tr><\/thead>
      Domain 1: Collection<\/td>17%<\/td>18%<\/td>+1%<\/td><\/tr>
      Domain 2: Storage and Data Management<\/td>17%<\/td>22%<\/td>+5%<\/td><\/tr>
      Domain 3: Processing<\/td>17%<\/td>24%<\/td>+8%<\/td><\/tr>
      Domain 4: Analysis and Visualization (combined in new)<\/td>29%<\/td>18%<\/td>-11%<\/td><\/tr>
      Domain 5: Security<\/td>20%<\/td>18%<\/td>-2%<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

      I am surprised that Analysis and Visualization has gone down\nfrom a combined score of 29% to just 18%. In an era where everything is\ncomprehended better using a visualization, I\u2019m not sure about AWS\nrationalization of reducing this section. <\/p>\n\n\n\n

      Based on folks who took the beta exam, below are some tips\nfor this new exam in terms of what to expect:  <\/p>\n\n\n\n

      Domain1: Collection<\/strong> – It is noted that the Kinesis<\/a> and Managed Streaming Kafka is\nabsolutely must know for this section with less emphasis on IoT now. How much of\nthat you would see in the real exam is yet to be known. <\/p>\n\n\n\n

      Domain2: Storage and Data Management<\/strong> – Scenario based questions\non S3, Glue Data Catalog, Redshift are common for this section. Not too many\nquestions on DynamoDB and should not be ignored. <\/p>\n\n\n\n

      Domain3: Processing \u2013 <\/strong>Must know for this section is AWS\nGlue, S3, Redshift processing, EMR – on which you might get scenario-based questions.\nBecause this domain introduces an assessment point focusing on automation,\nexpect to see some questions there. <\/p>\n\n\n\n

      Domain4: Analysis and Visualization \u2013 <\/strong>Without a doubt\nyou need to be familiar with Amazon QuickSight. Although it is one section in\nthe new exam, the points covered are just a condensed version of the old exam.<\/p>\n\n\n\n

      Domain5: Security \u2013 <\/strong>Encryption S3, EBS (server side and\nclient side) is the name of the game. You might see questions on integration\nwith AD.<\/p>\n\n\n\n

      With so many changes, time will tell which training providers will have the best course materials. Below are some important links that can help you for your preparation.<\/p>\n\n\n\n

      Meanwhile, the AWS preparation journeys<\/a> shouldn\u2019t change as much and there is still a lot of overlap between AWS BigData and AWS Data Analytic Certification.
