Exam question from Amazon's AWS Certified Solutions Architect - Associate SAA-C02

Question #: 282
Topic #: 1

[All AWS Certified Solutions Architect - Associate SAA-C02 Questions]

A company is backing up on-premises databases to local file server shares using the SMB protocol. The company requires immediate access to 1 week of backup files to meet recovery objectives. Recovery after a week is less likely to occur, and the company can tolerate a delay in accessing those older backup files.
What should a solutions architect do to meet these requirements with the LEAST operational effort?

A. Deploy Amazon FSx for Windows File Server to create a file system with exposed file shares with sufficient storage to hold all the desired backups.
B. Deploy an AWS Storage Gateway file gateway with sufficient storage to hold 1 week of backups. Point the backups to SMB shares from the file gateway.
C. Deploy Amazon Elastic File System (Amazon EFS) to create a file system with exposed NFS shares with sufficient storage to hold all the desired backups.
D. Continue to back up to the existing file shares. Deploy AWS Database Migration Service (AWS DMS) and define a copy task to copy backup files older than 1 week to Amazon S3, and delete the backup files from the local file store.

Ans B is correct. File Gateway integrates On-Premises DB or Apps server using mounts share NFS or SMB to create interface to File Gateway to S3 to backup like .bak files in S3.

I would go with B. you make local cache to be able to hold 7 days backup: Local disk storage on the gateway is used to temporarily hold changed data that needs to be transferred to AWS, and to locally cache data for low-latency read access. File Gateway automatically manages the cache maintaining the most recently accessed data based on client read and write operations. Data is evicted from the cache only when space is needed to store more recently used data. To maximize write performance, the gateway uses a write-back mechanism where data is first persisted to disk and then asynchronously uploaded to S3. The gateway serves data from the local cache to maximize read performance. If not present, data is efficiently synchronously fetched from Amazon S3 using byte-range gets. The local cache should generally be sized for the working set of data that you need low-latency access to. If the cache is too small then read latencies will increase as data being requested must be fetched from S3, and writes could fail if there is no free cache space to store data locally pending upload to S3.

I choose B first, then I found A is right . Since B use storage gateway ,and storage gateway actually just put files just in two place, S3 or Fsx windows file sever. A just use the latter. A and B both work, but A need no gateway, so A has least operation overhead

I would question why AWS is involved at all here given the scenario, what value does introducing FSX or SGW provide here at all?

Selected Answer: A

D => Totally wrong A, B and C are feasilbe, however base on elimination. 1) AWS EFS, it would be incorrect becasue we need a SMB Share. Athough we can create windows to acess NFS, but that will be additonal amound of operation work. So A is eliminated. 2) AWS Storage gateway and AWS Fx is technically feasilbe. However, AWS Storage would require setup of AWS Datasync, that will be addtioanl work. So B is elimated. The corect answer would be A (see) https://docs.aws.amazon.com/fsx/latest/WindowsGuide/getting-started-step2.html

This is a bad question, it is highly subject to interpretation. How fast does the backup need to be, must it be local speed (gateway) or is remote share fsx) fine? Which is harder to configure and maintain, a VPN to access your fsx share or a local appliance for file gateway? The way the question is worded I think B is the answer they are looking for.
