Storage Gateway

Question 1

Storage Gateway, on-premises applications

Answer 1

Advantage is monitoring and secure storage

Question 2

On premises storage gateway aws integrate services

Answer 2

IAM
KMS
AWS CloudTrail for logging account activity
Amazon CloudWatch for monitoring
Amazon EventBridge for monitoring alarms

Question 3

Your data at rest is encrypted by default using Amazon S3 server-side encryption (S3-SSE)

Answer 3

Data encrypted with Storage Gatway mechanism

Question 4

VMware vSphere High Availability

Answer 4

Health checks automatically recover from most service interruptions in under 60 seconds.

Question 5

Gatweay types

Answer 5

S3 File Gateway
FsX Gateway
Tape Gateway: cloud-based VTL
Volume Gateway: iSCSI target

Question 6

Stored Volume

Answer 6

If you need low-latency access to your entire dataset, first configure your on-premises gateway to store all your data locally. Then asynchronously back up point-in-time snapshots of this data to Amazon S3

Question 7

Cached Volume

Answer 7

In cached mode, primary data is stored in Amazon S3 and you retain your frequently accessed data locally in the cache.

Question 8

Upload Buffer

Answer 8

ffer. You can use on-premises DAS or SAN disks for working storage. Your gateway uploads data from the upload buffer over an encrypted Secure Sockets Layer (SSL) connection to the Storage Gateway running in the AWS Cloud. Storage Gateway then stores the data encrypted in Amazon S3 as Amazon EBS snapshots.

Question 9

AWS Backup

Answer 9

Centralized backup service that makes it straightforward and cost effective for you to back up your application data across AWS services in both the AWS Cloud and on premises.

Question 10

True False Stored volume is only available for on-premises host platform options.

Answer 10

True

Question 11

Volume Gateway Data Transfers

Answer 11

data through the on-premises Volume Gateway appliance to and from either storage area network (SAN) or virtual volumes. Your volume mode determines how reads and writes occur.

Question 12

write-back cache

Answer 12

is one in which write operations are directed to cache and completion is immediately acknowledged to the application.

Question 13

True False One hundred percent of the Read data on your volumes is stored virtually with stored volumes

Answer 13

False: it’s locally. cached volumes take advantage of both local and cloud.

Question 14

iSCSI protocol

Answer 14

is an IP-based storage networking standard for linking data storage facilities. It provides block-level access to storage devices by carrying Small Computer System Interface (SCSI) commands over a Transmission Control Protocol/Internet Protocol (TCP/IP) network using the default port 3260. iSCSI is used to facilitate data transfers over intranets and to manage storage over long distances

Question 15

Volume Clone

Answer 15

Instant clones offer rapid recovery of data to a gateway on premises. Cloning from an existing volume is faster and more cost effective than creating an Amazon EBS snapshot. Cloning does a byte-to-byte copy of your data from the source volume to the new volume, using the most recent recovery point from the source volume.

Question 16

Mananging the gatweway tasks

Answer 16

monitoring volume status and transitions, cloning or deleting a volume, creating snapshots, editing a snapshot schedule, and performing general maintenance.

Question 17

BOOTSTRAPPING

Answer 17

The gateway is synchronizing data locally with a copy of the data stored in AWS. You typically don’t need to take action for this status, because the storage volume automatically sees the Available status in most cases.

Question 18

CHAP

Answer 18

An iSCSI protocol that supports authentication between targets and initiators

(Internet Small Computer Systems Interface) as a transport protocol that provides for the SCSI block protocol to be carried over a TCP-based IP network,
