• Question 410:

  A company needs to connect on-premises applications to AWS Cloud storage by using industry-standard internet Small Computer Systems Interface (iSCSI) connectivity. Which AWS solution can the company use to meet this requirement?

  A. AWS Storage Gateway file gateway
  B. Amazon API Gateway
  C. AWS Storage Gateway volume gateway
  D. AWS Transit Gateway

  Explanation/Reference:

  The AWS solution that can be used to connect on-premises applications to AWS Cloud storage by using industry-standard internet Small Computer Systems Interface (iSCSI) connectivity is AWS Storage Gateway volume gateway.

  AWS Storage Gateway volume gateway is a hybrid storage service that enables on-premises applications to use AWS Cloud storage. It supports iSCSI connectivity, which allows applications to read and write data to AWS storage volumes using standard iSCSI initiators. Volume gateway provides two modes of operation: stored volumes and cached volumes. In stored volumes mode, entire datasets are stored on-premises, and a copy of the data
