1Z0-1072-25 Question 185
Single answerAn organization needs to store large monthly backup files in Oracle Cloud. Each backup can exceed 10 TB in size, and the team must retrieve any backup within a few hours when needed. The organization also wants to minimize storage costs. Which approach best satisfies both requirements?
- A
Store backup files in the Standard tier and rely on immediate availability for restores.
- B
Use Archive Storage for primary backups and rely on the fastest retrieval tier for an on-demand restore.
- C
Use Archive Storage for primary backups and set an Object Lifecycle Policy to move them to Standard every 30 days.
- D
Place backups in the Standard tier and move them to Archive Storage after 24 hours using a custom script.
Show answer and explanation
Correct answer: B
Explanation
Oracle Cloud Infrastructure Archive Storage is designed for infrequently accessed large objects, providing significantly lower cost than Standard tier. However, it still allows for expedited retrieval if you need the data within a few hours, making it ideal for large backup sets that are rarely accessed. For details, refer to Oracle� documentation on Object Storage tiers and retrieval options, which outlines best practices for balancing retrieval time requirements with cost optimization.
- A. Incorrect.
Option 1 (Store backup files in the Standard tier and rely on immediate availability) is technically feasible but is not cost-optimal for large, infrequently accessed backups. Standard tier charges are higher than Archive, so while it meets the retrieval requirement, it may not minimize costs.
- B. Correct.
Option 2 (Use Archive Storage for primary backups and rely on the fastest retrieval tier for an on-demand restore) is correct because Archive Storage is the most cost-effective for infrequent access. Oracle Cloud Infrastructure provides multiple retrieval tiers (e.g., bulk, standard, and expedited), which enable you to retrieve archived data within a few hours if you choose an expedited retrieval tier. This approach balances lower storage costs and meets the requirement for quick access when needed.
- C. Incorrect.
Option 3 (Use Archive Storage for primary backups and set an Object Lifecycle Policy to move them to Standard every 30 days) can be unnecessarily expensive because moving all data to the Standard tier every 30 days may defeat the purpose of using Archive for infrequent access. Also, you might not need to keep them in the Standard tier unless there is continuous access activity.
- D. Incorrect.
Option 4 (Place backups in the Standard tier and move them to Archive Storage after 24 hours using a custom script) complicates operational overhead and increases cost for the first 24 hours unnecessarily. Infrequent data should be placed in Archive right away unless there's a known reason to keep recent backups in Standard.
