Question : QuickTechie.com has an EC instance on which this website is running, but they realized that this instance is not good enough for heavy workload.
Hence they decided to upgrade EC2 instance, however, the attached volume (EBS) they do not want to loose so created a snapshot of the volume, after upgrading
the EC2 instance they attached the previous snapshot of EBS volume. Select the correct statemen in this scenerio...

1. New volumes created from existing Amazon S3 snapshots load lazily in the background.
2. New volumes created from existing Amazon S3 snapshots loaded first before starting new instance.
3. Access Mostly Uused Products by 50000+ Subscribers
4. New volumes created from existing Amazon S3 snapshots first needs to be decrypted first and then load lazily in the background.


Correct Answer : Get Lastest Questions and Answer :

Explanation: You can restore an Amazon EBS volume with data from a snapshot stored in Amazon S3. You need to know the ID of the snapshot you wish to restore your volume from and you need to
have access permissions for the snapshot. For more information on snapshots, see Amazon EBS Snapshots.

New volumes created from existing Amazon S3 snapshots load lazily in the background. This means that after a volume is created from a snapshot, there is no need to wait for all of
the data to transfer from Amazon S3 to your Amazon EBS volume before your attached instance can start accessing the volume and all its data. If your instance accesses data that
hasn't yet been loaded, the volume immediately downloads the requested data from Amazon S3, and continues loading the rest of the data in the background.

Amazon EBS volumes that are restored from encrypted snapshots are automatically encrypted. Encrypted volumes can only be attached to selected instance types.

Hence they decided to upgrade EC2 instance, however, the attached volume (EBS) they do not want to loose so created a snapshot of the volume, after upgrading

1. To avoid the possibility of increased read or write latency on a production workload, you should first access all of the blocks on the volume to ensure optimal
performance
2. To avoid the possibility of increased read or write latency on a production workload, you should wait all the data to be downloaded and then start EC2 instance
 3. Access Mostly Uused Products by 50000+ Subscribers
4. None of the above


Correct Answer : Get Lastest Questions and Answer :

Explanation: When a block of data on a newly restored Amazon EBS volume is accessed for the first time, you might experience longer than normal latency. To avoid the possibility of
increased read or write latency on a production workload, you should first access all of the blocks on the volume to ensure optimal performance; this practice is called pre-warming
the volume.

: You are using EBS volume for storing your website data, but you realized that the volume is about to fill. How can you increase the volume size.
1. Requesting AWS with the volume id
2. You can change volume size from AWS console
 3. Access Mostly Uused Products by 50000+ Subscribers
4. You can expand the storage space of an Amazon EBS volume by migrating your data to a larger volume and then extending the file system on the volume to recognize the
newly-available space.

5. None of the above


Correct Answer : Get Lastest Questions and Answer :

Explanation: Sometimes, you might need to increase the storage space of an existing volume without losing the data that is on the volume. You can expand the storage space of an Amazon EBS
volume by migrating your data to a larger volume and then extending the file system on the volume to recognize the newly-available space. After you verify that your new volume is
working properly, you can delete the old volume.

Question : Company B provides an online image recognition service and utilizes SQS to decouple system components for scaleability
. The SQS consumers poll the imaging queue as often as possible to keep end-to-end throughput as high as possible.
However, Company B is realizing that polling in tight loops is burning CPU cycles and increasing costs with empty responses.
How can Company B reduce the number empty responses? "Hint: these are API calls; if you're using an SDK, the SDK might use
