You work for a major news network in Europe. They have just released a new app
which allows users to report on events as and when they happen using their mobile
phone. Users are able to upload pictures from the app and then other users will be able
to view these pics. Your organization expects this app to grow very quickly, essentially
doubling it's user base every month. The app uses S3 to store the media and you are
expecting sudden and large increases in traffic to S3 when a major news event takes
place (as people will be uploading content in huge numbers). You need to keep your
storage costs to a minimum however and it does not matter if some objects are lost.
Which storage media should you use to keep costs as low as possible?
A.) S3 - OneZone-IA
B.) S3 - IA
C.) S3
D.) Glacier - Answer A
You have uploaded a file to S3. What HTTP code would indicate that the upload was
successful?
A. HTTP 404
B. HTTP 501
C. HTTP 307
D. HTTP 200 - Answer D
You run a meme creation website that frequently generates meme images. The original
images are stored in S3 and the metadata about the memes are stored in DynamoDB.
You need to store the memes themselves in a low-cost storage solution. If an object is
lost, you have created a Lambda function that will automatically recreate this meme
using the original file in S3 and the metadata in DynamoDB. Which storage solution
should you consider to store this non-critical, easily reproducible data on in the most
cost-effective solution as possible?
, a) S3
b) S3 - IA (Infrequently Accessed Storage)
c) S3 - OneZone-IA
d) Glacier - Answer C
You work for a busy digital marketing company who currently store their data on
premise. They are looking to migrate to AWS S3 and to store their data in buckets.
Each bucket will be named after their individual customers, followed by a random series
of letters and numbers. Once written to S3 the data is rarely changed, as it has already
been sent to the end customer for them to use as they see fit. However on some
occasions, customers may need certain files updated quickly, and this may be for work
that has been done months or even years ago. You would need to be able to access
this data immediately to make changes in that case, but you must also keep your
storage costs extremely low. The data is not easily reproducible if lost. Which S3
storage class should you choose to minimize costs and to maximize retrieval times?
a) S3
b) S3 - IA (Infrequently Accessed Storage)
c) S3 - OneZone-IA
d) Glacier - Answer B
What is Amazon Glacier?
A.) A highly secure firewall designed to keep everything out
B.) A tool that allows you to "freeze" an EBS volume
C.) It is a tool used to resurrect deleted EC2 snapshots
D.) An AWS service designed for long term data archival - Answer D
How many S3 buckets can you have per account by default?
A.) 50
B.) 100
C.) 10
D.) 20 - Answer B
You run a popular photo sharing website that depends on S3 to store content. You
generate revenue from your website via paid for adverts, however, you have discovered
that other websites are linking directly to the images on your site, and not to the HTML
pages that serve the content. This means that people are not seeing your adverts and
every time a request is made to S3 to serve an image it is costing your business money.
How could you resolve this issue?
A.) Use CloudFront to serve the static content.
B.) Remove the ability for images to be served publicly to the site and then use signed
URLs with expiry dates.
C.) Use security groups to blacklist the IP addresses of the sites that do this.
D.) Use EBS rather than S3 to store the content. - Answer B
