Exam Professional Cloud Architect topic 9 question 1 discussion

C Enable a bucket lifecycle management rule to delete objects older than 36 months. Use partitioned tables in BigQuery and set the partition expiration period to 36 months. is the right answer. When you create a table partitioned by ingestion time, BigQuery automatically loads data into daily, date-based partitions that reflect the data's ingestion or arrival time. Ref: https://cloud.google.com/bigquery/docs/partitioned-tables#ingestion_time And Google recommends you configure the default table expiration for your datasets, configure the expiration time for your tables, and configure the partition expiration for partitioned tables. Ref: https://cloud.google.com/bigquery/docs/best-practices-storage#use_the_expiration_settings_to_remove_unneeded_tables_and_partitions If the partitioned table has a table expiration configured, all the partitions in it are deleted according to the table expiration settings. For our specific requirement, we could set the partition expiration to 36 months so that partitions older than 36 months (and the data within) are automatically deleted. Ref: https://cloud.google.com/bigquery/docs/managing-partitioned-tables#partition-expiration
