4.What is the primary purpose of Amazon EBS Fast Snapshot Restore (FSR), which is separate from DLM lifecycle scheduling?
The primary purpose of Amazon EBS Fast Snapshot Restore (FSR) is to eliminate initial I/O latency (lazy-loading) by creating fully initialized EBS volumes that deliver maximum provisioned performance and single-digit millisecond latency the moment they are created
3.A company needs automated EBS snapshot copies in another AWS Region for disaster recovery. What should it consider when designing its DLM policy?
When designing an Amazon Data Lifecycle Manager (DLM) policy for cross-region EBS snapshot copies, a company should consider:
- Retention Periods: Set separate retention rules and expiration schedules for each target AWS Region independently of the source Region.
- Encryption & KMS Keys: Configure AWS Key Management Service (KMS) encryption keys and permissions for the destination Region if the source volume is encrypted.
- Region Limits: Limit cross-region copies to a maximum of three AWS Regions per single DLM policy.
- Incremental Copy Behavior: Note that deleting the most recent snapshot copy in the destination Region makes the next copy a full, non-incremental transfer
2.You want an EBS snapshot lifecycle policy to manage only volumes tagged Environment=Production. What should you configure?
To manage only EBS volumes tagged with Environment=Production using Amazon Data Lifecycle Manager (DLM), you need to configure a custom EBS snapshot lifecycle policy with specific target tags and parameters
1.What is the primary purpose of Amazon Data Lifecycle Manager (DLM) for Amazon EBS?
