Answer 17

1. Storage 2. Requests 3. Storage Management Pricing 4. Data Transfer Pricing 5. Transfer Acceleration

Answer 18

enables fast, easy and secure transfers of files over long distances between end users and an s3 bucket

Answer 19

Amazon's CloudFront's globally distributed edge locations. As the data arrives at an edge location - data is routed to Amazon S3 over an optimized network path.

Answer 20

○ The users upload their files to the edge location instead of directly uploading it to the S3 bucket. ○ Edge location - is a small Data Center that is near the user ○ Once uploaded, it is then sent over amazon's backbone network Instead of the user uploading it using their internet access directly to the S3 bucket, they are uploading it to the edge location then amazon have a much better communication between their edge locations and data centers which will be a lot faster.

Answer 21

* Bucket names must be unique across all existing bucket names in Amazon S3. * Bucket names must comply with DNS naming conventions. * Bucket names must be at least 3 and no more than 63 characters long. * Bucket names must not contain uppercase characters or underscores. * Bucket names must start with a lowercase letter or number. * Bucket names must be a series of one or more labels. Adjacent labels are separated by a single period (.). Bucket names can contain lowercase letters, numbers, and hyphens. Each label must start and end with a lowercase letter or a number. * Bucket names must not be formatted as an IP address (for example, 192.168.5.4).

Answer 25

1. Amazon manages the keys for you automatically so you don't have to worry about the keys at all 2. 256-bit Advanced Encryption Standard (AES-256)

Answer 26

You and amazon manage the keys together

Answer 27

Where you give amazon your own keys that you manage and you can encrypt your S3 objects doing that

Answer 28

you can only suspend it, if you want to delete it, you have to delete the bucket itself

Answer 29

Remove the delete marker in the versioning

Answer 30

Lifecycle rules

Answer 31

versioning to be turned on for the bucket

Answer 32

It will not copy existing files, it has to be manually moved

Answer 33

they will automatically be replicated in the target bucket

Answer 34

1. If you delete files from the source bucket, they won't be replicated in the target bucket 2. If you delete individual versions, it won't get replicated either

Answer 35

Content delivery network is a system of distributed servers that delivers webpages and other web content to a user based on geographic locations of the user, the origin of the webpage, and a content delivery server

Answer 36

location where the contents are cached

Answer 37

origin of all the files that the CDN will distribute. This can be an S3 bucket, EC2 instance, an Elastic Load Balancer or Route 53.

Answer 38

name given the CDN which consists of a collection of Edge Locations

Answer 48

> service that connects an on premise software appliance with cloud based storage to provide seamless and secure integration between an organization's on-premise IT environment and AWS's storage infrastructure > a virtual of physical device that's going to replicate your data into AWS (used to be virtual device but they've released a hardware appliance now so you can actually have a physical storage gateway)

Answer 49

available for download as a virtual machine (VM) image that you install on your datacenter

Answer 50

1. VMWare ESXi | 2. Microsoft Hyper V

Answer 51

1. File Gateway (NFS) 2. Volume Gateway (iSCSI) 3. Tape Gateway (VTL)

Answer 52

way of storing files in S3

Answer 53

a network file system (NFS) mount point

Answer 54

> presents your applications with disk volumes using the iSCSI block protocol. > Data written to these volumes can be asynchronously backed up as a point in time snapshots of your volumes, and stored in the cloud as Amazon EBS snapshots.

Answer 55

are incremental backups that capture only changed blocks. All snapshot storage is also compressed to minimize your storage charges

Answer 56

1. Stored Volumes - data written to your stored volumes is stored on your on prem storage hardware then it is asynchronously backed up to S3 in the form of EBS snapshots. (1GB - 16 TB in size for stored volumes) 2. Cached Volumes - uses S3 as the primary data storage while retaining frequently accessed data locally in your storage gateway. (1GB- 32 TB)

Answer 57

durable cost effective solution to archive your data in the AWS cloud

Answer 58

NetBackup, Backup Exec, Veeam

Answer 59

Yes. Amazon EC2 provides you the ability to pick the AZ to place resources, such as compute instances, within a region. When you use S3 One Zone-IA, S3 One Zone-IA assigns an AWS Availability Zone in the region according to available capacity.

Answer 60

Yes, you can have a bucket that has different objects stored in S3 Standard, S3 Standard-IA and S3 One Zone-IA.

Answer 61

override of an in progress restore to a faster restore tier if access to the data becomes urgent

Answer 62

You can retrieve 10GB of your Amazon S3 Glacier data per month for free with the AWS free tier.

Answer 63

Expedited, Standard, and Bulk Retrieval

Answer 64

Amazon S3 allows customers to run sophisticated queries against data stored without the need to move data into a separate analytics platform.

Answer 65

S3 Select is an Amazon S3 feature that makes it easy to retrieve specific data from the contents of an object using simple SQL expressions without having to retrieve the entire object.

Answer 66

Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL queries. Athena is serverless, so there is no infrastructure to setup or manage, and you can start analyzing data immediately.

Answer 67

Amazon Redshift Spectrum is a feature of Amazon Redshift that enables you to run queries against exabytes of unstructured data in Amazon S3 with no loading or ETL required. When you issue a query, it goes to the Amazon Redshift SQL endpoint, which generates and optimizes a query plan. Amazon Redshift determines what data is local and what is in Amazon S3, generates a plan to minimize the amount of Amazon S3 data that needs to be read, requests Redshift Spectrum workers out of a shared resource pool to read and process data from Amazon S3.

Answer 68

Amazon S3 event notifications can be sent in response to actions in Amazon S3 like PUTs, POSTs, COPYs, or DELETEs. Notification messages can be sent through either Amazon SNS, Amazon SQS, or directly to AWS Lambda.

Answer 69

There are no additional charges for using Amazon S3 for event notifications. You pay only for use of Amazon SNS or Amazon SQS to deliver event notifications, or for the cost of running an AWS Lambda function.
