A.Attaching an ENI to an instance when it is stopped.

B.This question doesn’t make sense.

C.Attaching an ENI to an instance when it is running

D.Attaching an ENI to an instance during the launch process

Answer:A

Attaching an ENI to an instance when it is stopped.

Explanation:

Warm Attach refers to attaching an Elastic Network Interface (ENI) to an Amazon EC2 instance when the instance is stopped.
Once attached, the ENI remains connected to the instance even after it is restarted.
Other attachment types include:
- Hot Attach: Attach an ENI to a running instance.
- Cold Attach: Attach an ENI during instance launch.

3.If your DB instance runs out of storage space or file system resources, its status willchange to_____ and your DB Instance will no longer be available.

A.storage-overflow

B.storage-full

C.storage-exceed

D.storage-overage

Answer:B

storage-full

Explanation:

When an Amazon RDS DB instance runs out of storage or file system resources, its status changes to storage-full.
In this state, the DB instance becomes unavailable until the storage is increased or the issue is resolved.
To prevent this, you can enable storage auto-scaling to automatically adjust the storage capacity.

4.How can you secure data at rest on an EBS volume?

A.Attach the volume to an instance using EC2’s SSL interface.

B.Write the data randomly instead of sequentially.

C.Encrypt the volume using the S3 server-side encryption service.

D.Create an IAM policy that restricts read and write access to the volume.

E.Use an encrypted file system on top of the EBS volume.

Answer:E

Use an encrypted file system on top of the EBS volume.

Explanation:

To secure data at rest on an Amazon EBS (Elastic Block Store) volume, you can:
- Use EBS encryption which encrypts data at rest automatically using AWS Key Management Service (KMS).
- Alternatively, use an encrypted file system (such as LUKS or BitLocker) on top of the EBS volume for an additional layer of security.
IAM policies can restrict access but do not encrypt data at rest.

5.What’s an ECU?

A.Extended Cluster User.

B.None of these.

C.Elastic Computer Usage.

D.Elastic Compute Unit.

Elastic Compute Unit.

Explanation:

ECU (Elastic Compute Unit) is a measure used by Amazon EC2 to provide a consistent metric to compare CPU performance across instance types.
It helps users estimate the compute power of an instance relative to a baseline, where 1 ECU is approximately equivalent to the CPU power of a 1.0–1.2 GHz 2007 Xeon processor.
