Free Alibaba Cloud ACA-BigData1 Sample Questions

Question 1

A Log table named log in MaxCompute is a partition table, and the partition key is dt. Anew partition is created daily to store the new data of that day. Now we have one month's data, starting from dt='20180101' to dt='20180131', and we may use ________ to delete the data on 20180101.

A. delete from log where dt='20180101'

Answer: A

Question 3

MaxCompute tasks contain computational tasks and non-computational tasks. The computational tasks require actual operations on data stored in the table. MaxCompute parses the task to obtain its execution plan, and submits the task for execution. The noncomputational tasks require substantial reading of and modification to metadata information. Therefore, the task is not parsed, and no execution plan is provided. The task is directly submitted for execution. The latter one has a faster response speed than the former one. Which of the following operations on the table t_test is a computational task?

A. desc t_test
B. alter table t_test add columns (comments string);
