How is provisioned throughput affected by the chosen consistency model when reading
data from a DynamoDB table?
A.
Strongly consistent reads use the same amount of throughput as eventually consistent
reads
B.
Strongly consistent reads use variable throughput depending on read activity
C.
Strongly consistent reads use more throughput than eventually consistent reads.
D.
Strongly consistent reads use less throughput than eventually consistent reads
I have the same idea. C

One read capacity unit represents one strongly consistent read per second, or two eventually consistent reads per second, for items up to 4 KB in size. If you need to read an item that is larger than 4 KB, DynamoDB will need to consume additional read capacity units. The total number of read capacity units required depends on the item size, and whether you want an eventually consistent or strongly consistent read.

Hi Simon, shouldn’t it be D then?
If “One read capacity unit represents one strongly consistent read per second, or two eventually consistent reads per second”
Thanks in advance.
