• Many AWS service use Amazon S3 a an integration
• Step 2 step approach to S3

Question 2

S3 use case : store object on

Answer 2

• Backup and storage
• Disaster recovery
• Archive
• Hybrid cloud storage
• Application hosting
• Media hosting
• Data lakes & big data analytics
• Software delivery
• Static website

Question 3

S3 security

Answer 3

• IAM policy ( user access to s3 IAM permission )
• S3 bucket policy (public access)
  EC2 instance access - for ec2 to access it need to have an ec2 instance role then add an IAM permission to the ec2 instance role to access s3

Question 4

Advanced: cross- Account Access

Answer 4

USE Bucket policy : create s3 bucket policy

Question 5

• Used : for audit purposes,
• have all access to s3 log buckets
• come down to the root cause of an issue,
• view suspicious patterns,

Question 8

S3 ReplicationS3 Replication (CRR & SRR)

Answer 8

same-region ( SRR):
use case: log aggregation, live replication between production and test accounts

• or cross-region (CRR) : use case: compliance, lower latency access, replication across accounts
• must enable versioning

Question 9

s3 storage classes

Question 10

Amazon S3 standard

Answer 10

• general General purpose
• 99.99% availability
• for frequently accessed data
• use case : big data analytic, mobile & gmailing application, content distribution

Question 11

Amazon S3 standard infrequent access (IA)

Answer 11

• not open frequently
• 99.9% availability
• for data less frequently accessed but returned rapid access when needed
• use cases: as a data store for disaster recovery, back up
• Which S3 Storage Class is suitable for less frequently accessed data, but with rapid access when needed, while keeping a high durability and allowing an Availability Zone failure

Question 12

Amazon S3 one Zone-infrequent access,

Answer 12

files you can recreate, and don’t rick losing it

A company stores copies of backups on Amazon S3 and requires rapid access but low resiliency. Which storage class is optimized for these requirements?

Question 13

Amazon S3 intelligent tiering

Answer 13

• costed optimized by automatically moving object between two access tires based on changing access patterns:
• not know if you should use frequent or infrequently access
• resilient against events that impact an entire availability zone

Question 14

S3 one zone - infrequent Access (IA)

Answer 14

• same as IA but data is stored in a single AZ
• 99.5% availability
• Use Case: storing secondary back copies of on-premise data or storing data you can recreate

is a low-cost, cloud-archive storage service that provides secure and durable storage for data archiving and online backup

Question 16

Amazon Glacier Deep archive

Answer 16

• a lot of archive
• low cost: cheapest

Question 17

s3 lifecycle rules

Answer 17

transition object between classes

What can you use to define actions to move S3 objects between different storage classes

Question 18

S3 Glacier vault lock / S3 object lock

Answer 18

WORM ( write once Read Many ),
- can not be touch or modify it even admin

• Which S3 feature should you use if you want to make sure that a policy will no longer be changed?

Question 19

Snow family: import data into s3 through a physical device, edge computing

Answer 19

Highly- secure, portable device to collect and process data at the edge, and migrate data into and out of AWS

Question 20

Data migration / Edge computing

Answer 20

Data migration: Long time to transfer data to aws
- snowcone: A research team deployed in a location with low-internet connection would like to move 5 TBs of data to the Cloud. Which service can it use?

• snowball edge : Which of the following services is a petabyte-scale data moving service (as a fleet) in or out of AWS with computing capabilities?
• snowmobile: Which of the following is an exabytes-scale data moving service in or out of AWS?

Edge computing:

• snowcone
• snowball edge

Question 21

Edge computing

Answer 21

anything that does not have internet, but process data

Use snowball edge /snowcone device

Question 22

OpsHub

Answer 22

• Desktop application to manage Snow family devices
• download for your computer \

Question 24

S3 Durability and availability :

Answer 24

Durability: how often you will leave a files

Availability: how readily available a serve is S3
