Questions 1–10 of 10

1. What is Delta Sharing?
Question 1A. A proprietary format for compressing database backupsB. An open protocol for secure data sharing in which recipients use their own compute powerC. A nightly batch job that copies data to partner organisationsD. A technique for masking personal data before exportE. A standard for naming countries in international transactions
2. In Delta Sharing, where does the shared data remain?
Question 2A. In the original datastore, accessed by recipients without data movementB. On the recipient's own servers after a full copyC. On removable media couriered to the recipientD. In a public download siteE. In the recipient's email inbox
3. Why has transferring large volumes of data to other organisations become impractical in the current era?
Question 3A. Because networks no longer support file transferB. Because data has become worthless to other organisationsC. Because data has grown exponentially and organisations do not want it to leave their datastores due to data sovereigntyD. Because regulators now forbid any form of data sharingE. Because databases can no longer export data
4. In the preceding era, why was giving outside parties access to an organisation's own environment kept very limited?
Question 4A. Because outside parties did not have internet accessB. Because encryption had not yet been inventedC. Because sharing data was illegal at the timeD. Because access to the environment and databases impacted performance and applications, which was not acceptableE. Because the organisations did not own the data
5. What practice arose in the earlier era because giving outsiders access to live databases hurt performance?
Question 5A. Deleting data after each quarterB. Storing data only in memoryC. Refusing all data requestsD. Publishing data on public websitesE. Masking or anonymising data and exporting the actual data to other datastores
6. Whose compute power is used when a recipient accesses data through Delta Sharing?
Question 6A. The recipient's own compute powerB. The data owner's compute powerC. A neutral third party's compute powerD. A government-run data centreE. No compute power is needed
7. How is the data presented to recipients under Delta Sharing?
Question 7A. As a complete unrestricted copy of every tableB. Only their relevant data, in encryption mode, with governance and compliance requirements in placeC. As printed reports posted by mailD. As anonymised summary statistics onlyE. As raw log files with no access controls
8. Which of the following is NOT a form of data sharing mentioned?
Question 8A. Sharing across departmentsB. Sharing across branchesC. Sharing across organisationsD. Sharing with the open wide world in a DaaS modelE. Sharing by deleting the data from the source
9. Under Delta Sharing, how can each party fund its access to relevant data?
Question 9A. By paying the data owner a fixed licence fee for computeB. By sharing the data owner's hardware for freeC. By spinning up their own compute power based on their own budgeted OPEXD. By buying the data outrightE. By using a government subsidy
10. What opportunity gave rise to Delta Sharing?
Question 10A. The need to store more data in fewer datastoresB. The need to convert SQL databases to NoSQLC. The need to eliminate data governanceD. The need to give access to an environment without using the owner's compute power, letting recipients use their ownE. The need to print data for archival
