Q1: A company needs to store large video files that are accessed infrequently. Which S3 storage class should they use?
Ans: Amazon S3 Glacier Deep Archive. S3 Glacier Deep Archive is the lowest-cost storage class and is designed for data that is rarely accessed and can tolerate retrieval times of 12 to 48 hours. It's ideal for storing large media files, like video, that are infrequently accessed.
Q2: An application requires block storage for file updates. The data is 500 GB and must continuously sustain 100 MiB/s of aggregate read/write operations. Which storage option is appropriate for this application?
Ans: Amazon EBS. Amazon EBS is designed to provide persistent block storage for EC2 instances, which is suitable for high-performance file updates, such as your application's requirement of sustaining 100 MiB/s of aggregate read/write operations. EBS volumes can be provisioned with performance characteristics (e.g., Provisioned IOPS) that match the required throughput, making it ideal for use cases with high and consistent I/O needs.
Q3: A news organization plans to migrate their 20 TB video archive to AWS. The files are rarely accessed, but when they are, a request is made in advance and a 3 to 5-hour retrieval time frame is acceptable. However, when there is a breaking news story, the editors require access to archived footage within minutes. Which storage solution meets the needs of this organization while providing the LOWEST cost of storage?
Ans: Store the archive in Amazon Glacier and pay the additional charge for expedited retrieval when needed. Amazon Glacier is a low-cost, long-term storage solution ideal for archiving data that is rarely accessed but must be retained. For this use case, since the video archive is rarely accessed, Glacier provides cost-effective storage, and for breaking news, expedited retrieval (within minutes) can be used when immediate access is required. The standard retrieval option in Glacier takes 3-5 hours, which is acceptable for planned requests. Expedited retrievals are available for urgent cases, with a small additional fee, making it a flexible and low-cost solution that meets both the regular archive access requirements and the occasional need for fast access.
Q4: A mobile application serves scientific articles from individual files in an Amazon S3 bucket. Articles older than 30 days are rarely read. Articles older than 60 days no longer need to be available through the application, but the application owner would like to keep them for historical purposes. Which cost-effective solution BEST meets these requirements?
Ans: Create lifecycle rules to move files older than 30 days to Amazon S3 Standard Infrequent Access and move files older than 60 days to Amazon Glacier. Lifecycle rules in S3 allow you to automatically transition objects between different storage classes based on their age. Amazon S3 Standard Infrequent Access (S3 Standard-IA) is ideal for data that is accessed less frequently but requires rapid access when needed, making it a good fit for files older than 30 days that are rarely read but still need to be accessible quickly. Amazon Glacier is a low-cost storage service for long-term archival, suitable for files older than 60 days that are no longer needed for immediate access but must be retained for historical purposes.
Q5: What is the maximum number of objects you can store in an S3 bucket?
Ans: There is no limit on the number of objects in a bucket.
Q6: How does S3 handle data replication?
Ans: S3 replicates data within the region for redundancy. You can also enable cross-region replication.
Q7: When should you use S3 Glacier?
Ans: For long-term archival storage where retrieval times are flexible.
Q8: What are the use cases for S3 Standard-IA?
Ans: For infrequently accessed data that still requires quick retrieval.
Q9: How does S3 Intelligent-Tiering optimize costs?
Ans: It automatically moves objects between access tiers to reduce costs based on usage patterns.
Q10: How do you change the storage class of an existing object?
Ans: Use the S3 console, CLI, or lifecycle policies to change storage classes.
Q11: What is the max number of tags you can assign to an S3 object?
Ans: Up to 10 tags per object.
Q12: How can you audit access to S3 data?
Ans: Enable S3 Server Access Logs and CloudTrail to monitor and audit data access.
Q13: What is Amazon Macie, and how does it relate to S3?
Ans: Macie uses machine learning to discover, classify, and protect sensitive data stored in S3.
Q14: How can you restrict access to S3 data from specific AWS services?
Ans: Use VPC endpoints with endpoint policies to control service access.
Q15: How do you restore a deleted object with versioning?
Ans: Remove the delete marker using the version ID.
Q16: Can you disable versioning once enabled?
Ans: No, but you can suspend it. Existing versions remain.
Q17: How can you automatically delete old object versions?
Ans: Use lifecycle policies to set an expiration rule on non-current versions.
Q18: What happens if you upload an object with the same key?
Ans: It overwrites the existing object.
Q19: What is the difference between CopyObject and UploadObject?
Ans: CopyObject copies an object within or between buckets, while UploadObject uploads a new object.
Q20: How can you improve the upload speed to S3?
Ans: Use multipart upload, Transfer Acceleration, and S3 lifecycle policies for optimization.
