A. B. C. D.Answer: C.
Option A is incorrect - volume gateway provides cloud-backed storage volumes that you can mount as Internet Small Computer System Interface (iSCSI) devices from your on-premises application servers.
The gateway supports the following volume configurations:
Cached volumes - You store your data in Amazon Simple Storage Service (Amazon S3) and retain a copy of frequently accessed data subsets locally.
Cached volumes offer a substantial cost savings on primary storage and minimize the need to scale your storage on- premises.
You also retainlow-latency access to your frequently accessed data.
Stored volumes - 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
This configuration provides durable and inexpensive offsite backups that you can recover to your local data center or Amazon EC2
For example, if you need replacement capacity for disaster recovery, you can recover the backups to Amazon EC2
https://docs.aws.amazon.com/storagegateway/latest/userguide/WhatIsStorageGateway.htmlOption B is incorrect -A file gateway supports a file interface into Amazon Simple Storage Service (Amazon S3) and combines a service and a virtual software appliance.
By using this combination, store and retrieve objects in Amazon S3 using industry-standard file protocols such as Network File System (NFS) and Server Message Block (SMB)
The software appliance, or gateway, is deployed into your on-premisesenvironment as a virtual machine (VM) running on VMware ESXi or Microsoft Hyper-V hypervisor.
The gateway provides access to objects in S3 as files or file share mount points.
With a file gateway, you can do the following:
You can store and retrieve files directly using the NFS version 3 or 4.1 protocol.
You can store and retrieve files directly using the SMB file system version, 2 and 3 protocol.
You can access your data directly in Amazon S3 from any AWS Cloud application or service.
You can manage your Amazon S3 data using lifecycle policies, cross-region replication, and versioning.
You can think of a file gateway as a file system mount on S3
https://docs.aws.amazon.com/storagegateway/latest/userguide/WhatIsStorageGateway.htmlOption C is correct -With a tape gateway, cost-effectively and durably archive backup data in Glacier.
A tape gateway provides a virtual tape infrastructure that scales seamlessly with your business needs and eliminates the operational burden of provisioning, scaling, and maintaining a physical tape infrastructure.
https://docs.aws.amazon.com/storagegateway/latest/userguide/WhatIsStorageGateway.htmlMSP Bank is considering using AWS Storage Gateway to seamlessly integrate their on-premises IT environment with the AWS storage infrastructure. AWS Storage Gateway is a hybrid storage service that enables on-premises applications to seamlessly use AWS cloud storage. It provides three different types of gateways, which are Volume Gateway, File Gateway, and Tape Gateway.
Volume Gateway: This type of gateway provides block storage to the applications. It presents the application with disk volumes using the iSCSI protocol. It stores the data on-premises and asynchronously replicates the data to Amazon S3 or Amazon EBS. There are two modes of Volume Gateway:
- Cached Volumes: In this mode, the primary data storage is on S3, and frequently accessed data is cached on-premises.
- Stored Volumes: In this mode, the primary data storage is on-premises, and backups are stored in S3.
File Gateway: This type of gateway provides file storage to applications using the NFS and SMB protocols. It stores the data in Amazon S3, and the application can access it as files. The gateway caches frequently accessed data on-premises, providing low-latency access to the data.
Tape Gateway: This type of gateway provides a virtual tape infrastructure to the applications. It stores the data on Amazon S3 and provides access to it using the iSCSI protocol. It integrates with existing backup applications using the Virtual Tape Library (VTL) interface. It eliminates the operational burden of provisioning, scaling, and maintaining a physical tape infrastructure.
Considering MSP Bank's requirement to cost-effectively and durably archive backup data in Glacier, Tape Gateway seems to be the most appropriate option. Tape Gateway provides a virtual tape infrastructure that stores the data on Amazon S3 and provides access to it using the iSCSI protocol, which is compatible with Glacier. It eliminates the operational burden of provisioning, scaling, and maintaining a physical tape infrastructure, making it a cost-effective solution for backup and archival purposes.
Therefore, the correct answer is (C) Tape Gateway.
