Exam AWS Certified Database - Specialty topic 1 question 70 discussion

Ans:CD Dynamodb doesn't have a throughput optimized table type

A. Change the table to use Amazon DynamoDB Streams --> Doesnt make any sense for the given problem. B. Purchase DynamoDB reserved capacity in the affected Region --> reserved capacity is not going to give you anything more than you reserve C. Increase the write capacity units for the specific table --> This could be an answer. But the exception is thrown when survey responses are collected which appears to be a read operation. D. Change the table capacity mode to on-demand --> This is correct answer https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/switching.capacitymode.html E. Change the table type to throughput optimized --> There is no such thing as throughput optimized in dynamoDB I will go with C,D

C. Increase the write capacity units for the specific table D. Change the table capacity mode to on-demand

My answer

C and D - Any setting will be on Table level for DynamoDB

Ans:CD

C and D are not compatible. If you use on-demand mode, you don´t change read/write capacity.

ANS : C & D.

C. Increase the write capacity units for the specific table --> This could be an answer. As the exception is thrown when survey responses are collected which is write operation. D. Change the table capacity mode to on-demand --> This is correct answer https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/switching.capacitymode.html

CD Whoever writes these questions should go for English grammar classes!! both options cannot go togeher which means a question like "What is database specialist's role in this?" makes little sense. What would have made sense is "What are the options a specialist can try to remediate this problem?"

C & D are the absolutely correct answers.

Correct answers

C,D: Valid

C and D are the only correct options. Although both cannot go together. Question does not clarify that both options should apply or either of it.

Ans: CD

Should be C OR D, right... because either would work, but you cannot have both. On-demand does not allow you to set write capacity??? The only 2 answers that fit together are B and C, as both are about provisioned capacity. But B is very unlikely here, although may be a good practice overall.

yes, C & D
