• Question 125:

  You are about to deploy an e-business application on Oracle Cloud Infrastructure and one of the requirements is to use a shared file system that supports the NFS protocol. Which storage service would meet this requirement?

  A. object storage
  B. block volume
  C. data transfer appliance
  D. file storage
  D. file storage

  ---

  Use the File Storage service when your application or workload includes big data and analytics, media processing, or content management, and you require Portable Operating System Interface (POSIX)-compliant file system access

  semantics and concurrently accessible storage. The File Storage service is designed to meet the needs of applications and users that need an enterprise file system across a wide range of use cases, including the following:

  General Purpose File Storage: Access to an unlimited pool of file systems to manage growth of structured and unstructured data.

  Big Data and Analytics: Run analytic workloads and use shared file systems to store persistent data. Lift and Shift of Enterprise Applications: Migrate existing Oracle applications that need NFS storage, such as Oracle E-Business Suite and

  PeopleSoft.

  Databases and Transactional Applications: Run test and development workloads with Oracle, MySQL, or other databases.

  Backups, Business Continuity, and Disaster Recovery: Host a secondary copy of relevant file systems from on premises to the cloud for backup and disaster recovery purposes. MicroServices and Docker: Deliver stateful persistence for

  containers. Easily scale as your container- based environments grow.

• Question 126:

  You need to transfer over 12 TB of data from on-premises to your cloud account. You started copying this data over the internet and noticed that it will take too long to complete. Without increasing the costs of your subscription, what is the recommended way to send this amount of data to your cloud account?

  A. Use Data Transfer Service to send your data.
  B. Split the data into multiple parts and use the multipart tool.
  C. Use a 10 GB FastConnect line to send the data.
  D. Send the data over a VPN IPsec tunnel.
  E. Compress the data and use the multipart tool.
  A. Use Data Transfer Service to send your data.

  Overview of Data Transfer Service

  Oracle offers offline data transfer solutions that let you migrate data to Oracle Cloud Infrastructure. Moving data over the public internet is not always feasible due to high network costs, unreliable network connectivity, long transfer times, and

  security concerns. Our transfer solutions address these pain points, are easy to use, and provide significantly faster data upload compared to over-the- wire data transfer.
