Exam AWS Certified Solutions Architect - Professional topic 1 question 818 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 818
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company wants to use Amazon S3 to back up its on-premises file storage solution. The company's on-premises file storage solution supports NFS, and the company wants its new solution to support NFS. The company wants to archive the backup files after 5 days. If the company needs archived files for disaster recovery, the company is willing to wait a few days for the retrieval of those files.
Which solution meets these requirements MOST cost-effectively?

  • A. Deploy an AWS Storage Gateway files gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the file gateway. Create an S3 Lifecycle rule to move the file to S3 Standard-Infrequent Access (S3 Standard-IA) after 5 days.
  • B. Deploy an AWS Storage Gateway volume gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the volume gateway. Create an S3 Lifecycle rule to move the files to S3 Glacier Deep Archive after 5 days.
  • C. Deploy an AWS Storage Gateway tape gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the tape gateway. Create an S3 Lifecycle rule to move the files to S3 Standard-Infrequent Access (S3 Standard-IA) after 5 days.
  • D. Deploy an AWS Storage Gateway file gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the tape gateway. Create an S3 Lifecycle rule to move the files to S3 Standard-Infrequent Access (S3 Standard-IA) after 5 days.
  • E. Deploy an AWS Storage Gateway file gateway that is associated with an S3 bucket. Move the files from the on-premises file storage solution to the file gateway. Create an S3 Lifecycle rule to move the files to S3 Glacier Deep Archive after 5 days.

Selected Answer: E
We want Glacier deep archive as that is the cheapest and they can wait for the files in DR solution. File gateway is a type of storage gateway, which leave 2 correct answers. Go with file gateway as that is the correct type. E. But its a poor question as Storage Gateway isn't wrong, just not specific.

Between A and E... I would go for A since Data in S3 can move to Deep Glacier only after 90days.

I go for E. "a few days" is enough. The new Glacier Deep Archive storage class is designed to provide durable and secure long-term storage for large amounts of data at a price that is competitive with off-premises tape archival services. Data is stored across 3 or more AWS Availability Zones and can be retrieved in 12 hours or less.

E Only File Gateway will support NFS and since the wait time for retrieval is few days Glacier deep archive is also fit.

Selected Answer: B
cost-effectiveness is the key while chosing the tier of s3. Once they're ok to wait couple of days it should be Glacier Deep Archive. Deep Archive option rules out A,C,D Once they have custom solution for storage it should be volume gateway
