  4. 4What is the default consistency model for DynamoDB?
    1. AEventually consistent reads
    2. BImmediately consistent reads
    3. CEventually pristine reads
    4. DEventually consistent writes
  5. 5Which of the following are supported consistency models for DynamoDB? (Choose two.)
    1. AEventually consistent reads
    2. BStrongly consistent writes
    3. CImmediately consistent reads
    4. DStrongly consistent reads
  6. 6You are a solutions architect for a data-driven company using DynamoDB. They want to
    ensure always-accurate responses, so they have enabled strongly consistent reads. However,
    API calls to read data sometimes do not immediately return, and sometimes fail.
    What possible causes could there be? (Choose two.)
    1. AA recent write was made and is not yet complete. As a result, a read operation is
      delayed waiting on the write operation to complete.
    2. BA recent write was made and is replicating to the secondary instance. Until that replication
      completes, the read operation will lag.
    3. CA network outage has interrupted a recent read, and subsequent reads of that data are
      delayed as a result.
    4. DA network outage has interrupted a recent write, and subsequent reads of that data
      are delayed as a result.
