Question

If you want low-latency access to your entire dataset stored in Amazon S3 as mounted iSCSI devices and need asynchronous backup snapshots to S3, what type of storage gateway should you select and how should you configure it?

a) Volume gateway with cached volumes
b) Volume gateway with stored volumes
c) Tape gateway
d) File gateway

Answer 1

To achieve low-latency access to your dataset stored in Amazon S3 with asynchronous backup snapshots, select Volume gateway with cached volumes as the storage gateway type.

Step-by-step explanation:

If you want low-latency access to your entire dataset stored in Amazon S3 as mounted iSCSI devices and need asynchronous backup snapshots to S3, you should select Volume gateway with cached volumes as the type of storage gateway. With Volume gateway, you can store your entire dataset in S3 and access it using iSCSI devices with low latency. By configuring cached volumes, frequently accessed data is cached on-premises for fast access, while the entire dataset is backed up asynchronously to S3 for durability.
