7How is data stored in Amazon Simple Storage Service (Amazon S3) for high durability?
- AData is automatically replicated to other regions.
- BData is automatically replicated within a region.
- CData is replicated only if versioning is enabled on the bucket.
- DData is automatically backed up on tape and restored if needed.
8Based on the following Amazon Simple Storage Service (Amazon S3) URL, which one of the following statements is correct?

- BThe object "myfile.doc" is stored in the bucket "bucket1.abc.com."
- CThe object "folderx/myfile.doc" is stored in the bucket "bucket1.abc.com."
- DThe object "myfile.doc" is stored in the bucket "bucket1."
9To have a record of who accessed your Amazon Simple Storage Service (Amazon S3) data and from where, you should do what?
- AEnable versioning on the bucket.
- BEnable website hosting on the bucket.
- CEnable server access logs on the bucket.
- DCreate an AWS Identity and Access Management (IAM) bucket policy.
- EEnable Amazon CloudWatch logs.
10What are some reasons to enable cross-region replication on an Amazon Simple Storage Service (Amazon S3) bucket? (Choose 2 answers)
- AYou want a backup of your data in case of accidental deletion.
- BYou have a set of users or customers who can access the second bucket with lower latency.
- CFor compliance reasons, you need to store data in a location at least 300 miles away from the first region.
- DYour data needs at least five nines of durability.
11Your company requires that all data sent to external storage be encrypted before being sent. Which Amazon Simple Storage Service (Amazon S3) encryption solution will meet the requirement?

- CClient-side encryption with customer-managed keys
- DServer-side encryption with AWS Key Management Service (AWS KMS) keys (SSE-KMS)
12You have a popular web application that accesses data stored in an Amazon Simple Storage Service (Amazon S3) bucket. You expect the access to be very read-intensive, with expected request rates of up to 500 GETs per second from many clients. How can you increase the performance and scalability of Amazon S3 in this case?

- BEnable a lifecycle rule to migrate data to the second region.
- CEnable static website hosting.
- DCreate an AWS Identity and Access Management (IAM) policy to allow Amazon S3 to replicate objects on your behalf.
14Your company has 100 TB of financial records that need to be stored for seven years by law. Experience has shown that any record more than one-year old is unlikely to be accessed. Which of the following storage plans meets these needs in the most cost effective manner?
