A company has a set of EC2 instances hosted in AWS. These instances have EBS volumes for storing critical information. There is a business continuity requirement and in order to boost the agility of the business and to ensure data durability which of the following options are not required.

Please select:

A.
Use lifecycle policies for the EBS volumes
Answers
A.

B.
Use EBS Snapshots
Answers
B.
Use EBS Snapshots
C.
Use EBS volume replication
Answers
C.
Use EBS volume replication
D.
Use EBS volume encryption
Answers
D.
Use EBS volume encryption
Suggested answer: C, D

Explanation:

Data stored in Amazon EBS volumes is redundantly stored in multiple physical locations as part of normal operation of those services and at no additional charge. However, Amazon EBS replication is stored within the same availability zone, not across multiple zones; therefore, it is highly recommended that you conduct regular snapshots to Amazon S3 for long-term data durability. You can use Amazon Data Lifecycle Manager (Amazon DLM) to automate the creation, retention, and deletion of snapshots taken to back up your Amazon EBS volumes. With lifecycle management, you can be sure that snapshots are cleaned up regularly and keep costs under control. EBS Lifecycle Policies

A lifecycle policy consists of these core settings:

• Resource type—The AWS resource managed by the policy, in this case, EBS volumes.

• Target tag—The tag that must be associated with an EBS volume for it to be managed by the policy.

• Schedule—Defines how often to create snapshots and the maximum number of snapshots to keep. Snapshot creation starts within an hour of the specified start time. If creating a new snapshot exceeds the maximum number of snapshots to keep for the volume, the oldest snapshot is deleted.

Option C is correct. Each Amazon EBS volume is automatically replicated within its Availability Zone to protect you from component failure, offering high availability and durability. But it does not have an explicit feature like that. Option D is correct Encryption does not ensure data durability
