Topic 1 Question 679
3 つ選択A company wants to back up its on-premises virtual machines (VMs) to AWS. The company's backup solution exports on-premises backups to an Amazon S3 bucket as objects. The S3 backups must be retained for 30 days and must be automatically deleted after 30 days.
Which combination of steps will meet these requirements?
Create an S3 bucket that has S3 Object Lock enabled.
Create an S3 bucket that has object versioning enabled.
Configure a default retention period of 30 days for the objects.
Configure an S3 Lifecycle policy to protect the objects for 30 days.
Configure an S3 Lifecycle policy to expire the objects after 30 days.
Configure the backup solution to tag the objects with a 30-day retention period

In theory, E alone would be enough because the objects are "retained for 30 days" without any configuration as long as no one deletes them. But let's assume that they want us to prevent deletion.
A: Yes, required to prevent deletion. Object Lock requires Versioning, so if we 'create an S3 bucket that has S3 Object Lock enabled' that this also has object versioning enabled, otherwise we would not be able to create it.
B: No. We need versioning, but we cannot "create" the bucket twice. If we create it "with object lock enabled" then versioning is enabled too, but NOT the other way round (creating it with versioning enabled will not automatically enable object lock).
👍 3pentium752024/01/03 ABE -> https://docs.aws.amazon.com/AmazonS3/latest/userguide/object-lock.html A. Create an S3 bucket that has S3 Object Lock enabled. -> You set a Retention period of 30 days with this feature. B. Create an S3 bucket that has object versioning enabled -> Object Lock works only in buckets that have S3 Versioning enabled E. Configure an S3 Lifecycle policy to expire the objects after 30 days. -> It is valid using the lifecicle policy.
