A healthcare analytics platform ingests raw genomic sequencing data into Google Cloud Storage. The data undergoes intensive analytical processing during its first 14 days. After 14 days, the files are rarely accessed, but regulatory compliance mandates that all raw sequence files must be preserved for at least 7 years. Additionally, business continuity policies require that the data be synchronously replicated across two specific geographic regions within North America to guarantee continuous availability during a regional outage. Which TWO configuration steps should the Cloud Engineer implement to satisfy both operational and cost-optimization requirements? (Select TWO)
- Create the Cloud Storage bucket with a Dual-region location setting specifying the two required North American regions.Answer
- BConfigure an Object Lifecycle Management rule to set the bucket's default storage class to Coldline immediately upon object creation.
- Configure an Object Lifecycle Management rule to transition objects from Standard storage class to Archive storage class 14 days after creation.Answer
- DDisable Uniform Bucket-Level Access and configure per-object Access Control Lists (ACLs) to manage object storage classes.
Answer
The Cloud Engineer should create a bucket using a Dual-region location setting across the designated regions and apply an Object Lifecycle Management rule transitioning objects from Standard to Archive storage class after 14 days.
Selecting a Dual-region location ensures data replication between the two designated North American regions for high availability. Setting an Object Lifecycle Management rule to move objects from Standard to Archive storage class after 14 days ensures low-cost long-term storage while avoiding retrieval charges during the active analytical processing window.
