Answer is B.
BigQuery transparently and automatically provides highly durable, replicated storage in multiple locations and high availability with no extra charge and no additional setup.
@xhova: https://cloud.google.com/bigquery-transfer/docs/locations What it mentions here is once you create a replication. YOu cannot change a location. Here the question is about high availability. synchronous replication.
👍 15ronron892020/12/11Answer is B. Pick BigQuery with multi-region A multi-region is a large geographic area, such as the United States (US) or Europe (EU), that contains two or more geographic places. In a multi-region, data is stored in a single region but is backed up in a geographically-separated region to provide resilience to a regional disaster. The recovery and failover process is managed by BigQuery. https://cloud.google.com/bigquery/docs/availability#multi_regions
👍 2tzKhalil2021/05/10Answer A Automatic Replication of Data in different regions is not supported by Big Query. https://cloud.google.com/bigquery/docs/availability It states - "In a single region, data is stored only in the region. There is no Google Cloud–provided backup or replication to another region. If you want to use a single region for your datasets but consider the lack of backup or replication too risky, you can create cross-region dataset copies to enhance your disaster recovery guarantees." So this question specifically asked for "Automatic Data Replication" and it's only possible with Big Table. So Answer is A.
