| Question | Answer |
| 1:Your company has petebytes of data that it wants to move from their on-premise network to AWS. What AWS solution should you use? | Snowball is a service provided by AWS for moving extremely large (petabytes) of data into AWS. |
| 2: You are currently running an application on AWS that host customers' photo albums. For each main photo uploaded, your application generates a thumbnail for use in the mobile version of the application. What is the most cost effective storage solution, while also providing the highest level of availability and durability? | Since the customers' main photos cannot be reproduced, storing them in the standard storage class will provide the highest level of availability and durability. The thumbnails can be easily reproduced from the main photos, so you can store them in reduced redundancy storage, which how lower durability - but is cheaper than standard. |
| 3: What is the object durability and availability advertised by AWS for their S3 standard storage service? | Durability: 99.999999999 Availability: 99.99 |
| 4: True or False: The S3 infrequent access (S3-IA) storage class has object durability of 99.999999999% and availability of 99.90% | True |
| 5: Through what process are objects moved from the standard storage class to Glacier? | Objects uploaded and stored using the standard storage class must use lifecycles to move them to Glacier. |
| 6: You work for a hospital that is required to store patient's medical records for a minimum of 10 years. Most of these records will never be accessed but must be made available upon request (within a few hours). What is the most cost-effective storage option? | Glacier |
| 7: What best describes what occurs when you suspend object versioning? | When you suspend versioning, S3 retains all current and existing past versions. However, all new objects will overwrite the existing current version. No new versions will be created. |
| 8: True or False: S3 can be used as an option for lost-cost, reliable web hosting for dynamic web sites. | False. It can be done for static web sites. |
| 9: True or False: All S3 buckets are private by default. | True |
| 10: If need to upload a file to S3 that is 500MB in size., what data transit option should you use? | Multi-part upload should be used uploading any file over 100MB in size (up to 5GB in size). Single operation upload cloud be used but is not recommended. Import/export and Snowball are used for datasets that are larger than 5GB. |
