Exam Professional Cloud Database Engineer topic 1 question 89 discussion

Create the database on a Bare Metal Solution server with the database running on flash storage. Keep a local backup copy on standard storage. Keep backups older than one day stored in Actifio OnVault storage.

Bare Metal --> RMAN

Option B is correct There are two activities: Manage incremental backup (transaction log) and manage obsolete backup (older than retention time to another backup storage (archival)). Option B make as actifio as tool to organize this two activities while Option D make RMAN as tools to organize this to activities. actifio have feature like “Incremental-forever” backups" and store in OnVault storage which is official standard for actifio and actifio in gcp which is very fast compare to option D (RMAN). RMAN will need more than 2 hours to do recovery for 50 TB.

Keeping local storage on flash drive would meet the requirement for RTO. And moving older backups to Archival storage is the cost-effective option.

correct answer is C. Option C aligns with the requirements for performance, cost-effectiveness, and long-term data retention while meeting the RTO and RPO objectives.

C Creating the database on a Bare Metal Solution server with the database running on flash storage will ensure high performance and low latency, which is critical for achieving the RTO and RPO objectives. Keeping a local backup copy on standard storage will provide a quick restore option in case of any issues or failures within the Bare Metal Solution environment. This allows for faster recovery when needed. Using the Oracle Recovery Manager (RMAN) backup utility to move backups older than one day to a Coldline Storage bucket is a cost-effective solution for long-term data retention. Coldline Storage is designed for data archival and offers a lower cost compared to other storage options. By using RMAN, the backup process can be automated and scheduled, ensuring that the backups are regularly moved to the Coldline Storage bucket.

HDD (hard drive) for Local backups or archival workloads

GCP wants us to choose B

RMAN cannot move backups to storage buckets. B

D is an answer

D is an answer

D: Create the database on a Bare Metal Solution server with the database running on flash storage. Archive storage ARCHIVE 365 days Yes • 99.95% in multi-regions and dual-regions • 99.9% in regions Keep a local backup copy on all flash storage. Use the Oracle Recovery Manager (RMAN) backup utility to move backups older than one day to an ***** Archive Storage bucket.
