1.Select the most correct answer: The device name /dev/sda1 (within Amazon EC2) is _____

A. Possible for EBS volumes

B.Reserved for the root device

C.Recommended for EBS volumes

D.Recommended for instance store volume

Answer:B

Reserved for the root device

Explanation:

In Amazon EC2, the device name /dev/sda1 is reserved for the root volume of an instance.
This root volume is typically an EBS volume (for most modern instance types) or an instance store volume (for some older instance types).
Other EBS volumes or instance store volumes can be attached using device names like /dev/sdf, /dev/sdg, etc.
The root volume contains the operating system and is essential for instance booting.

2.Before I delete an EBS volume, what can I do if I want to recreate the volume later?

A.Create a copy of the EBS volume (not a snapshot)

B.Store a snapshot of the volume

C.Download the content to an EC2 instance

D.Back up the data in to a physical disk

Answer:B

Store a snapshot of the volume

Explanation:

Before deleting an Amazon EBS volume, you can create a snapshot to preserve its data.
EBS Snapshots are stored in Amazon S3 and can be used later to recreate the volume.
When you restore a volume from a snapshot, you can create it in any Availability Zone within the same AWS Region.
Simply creating a copy of the volume is not possible without first making a snapshot.

3.While creating the snapshots using the API, which Action should I be using?

A.MakeSnapShot

B.FreshSnapshot

C.DeploySnapshot

D.CreateSnapshot

Answer:D

CreateSnapshot

Explanation:

When creating an EBS snapshot using the AWS API, you should use the CreateSnapshot action.
This API call creates a point-in-time backup of an EBS volume, which can later be used to restore or create new volumes.
Other options like “MakeSnapshot,” “FreshSnapshot,” and “DeploySnapshot” are not valid AWS API actions.

4.Is Federated Storage Engine currently supported by Amazon RDS for MySQL?

A.Only for Oracle RDS instances

B.No

C.Yes

D.Only in VPC

Answer:A

Explanation:

Amazon RDS for MySQL does not support the Federated Storage Engine.
The Federated Engine allows a MySQL server to access tables from a remote MySQL database as if they were local.
However, AWS disables this feature in RDS for security and managed service constraints.
If you need similar functionality, consider using Amazon RDS Read Replicas or AWS Database Migration Service (DMS) for cross-database access.

5.Which Amazon Storage behaves like raw, unformatted, external block devices that you can attach to your instances?

A.None of these.

B.Amazon Instance Storage

C.Amazon EBS

D.All of these

Answer:C

Amazon EBS

Explanation:

Amazon Elastic Block Store (EBS) provides raw, unformatted block storage that can be attached to EC2 instances.
You can format EBS volumes with a file system (e.g., ext4, XFS, NTFS) or use them as raw block devices.
Amazon Instance Store also provides block storage, but it is temporary and data is lost when the instance stops or terminates.
EBS persists data even after the instance is stopped and is the recommended option for most workloads needing durable storage
