Question #: 499
Topic #: 1

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

A company is hosting its website by using Amazon EC2 instances behind an Elastic Load Balancer across multiple Availability Zones. The instances run in an
EC2 Auto Scaling group. The website uses Amazon Elastic Block Store (Amazon EBS) volumes to store product manuals for users to download. The company updates the product content often, so new instances launched by the Auto Scaling group often have old data. It can take up to 30 minutes for the new instances to receive all the updates. The updates also require the EBS volumes to be resized during business hours.
The company wants to ensure that the product manuals are always up to date on all instances and that the architecture adjusts quickly to increased user demand.
A solutions architect needs to meet these requirements without causing the company to update its application code or adjust its website.
What should the solutions architect do to accomplish this goal?

A. Store the product manuals in an EBS volume. Mount that volume to the EC2 instances.
B. Store the product manuals in an Amazon S3 bucket. Redirect the downloads to this bucket.
C. Store the product manuals in an Amazon Elastic File System (Amazon EFS) volume. Mount that volume to the EC2 instances.
D. Store the product manuals in an Amazon S3 Standard-Infrequent Access (S3 Standard-IA) bucket. Redirect the downloads to this bucket.

agree C. EFS provides scalable file system storage for EC2. You can create an EFS file system and configure your instances to mount the file system. You can use an EFS file system as a common data source for workloads and applications running on multiple instances.

So basically, the requirement is for shared storage for multiple EC2 instances. Answer would be EFS....

I agree with C, for me the key in the answer is ... without causing the company to update its application code or adjust its website... I like S3 but some changes need to be deployed to the app. and its website. so I go with C.

S3 is object based storage, EBS is block based, EFS is file based, you are anyways changing in any case.

B or C. B is cheaper, but needs to rewrite web application to use it. C EFS volume can be just mounted as NFS and used by all instances without any other changes. I would go with C.

Key to the question: --> Mutli AZ, auto scaled EC2 architecture --> Website is using EBS for storing the data --> New instances are taking 30mins to have new data, so high downtime --> resizing also involves downtime Expectation: updated data available in all ec2 instances wihtout change in business arch Distractors -- A/C/D A is a distractor because EBS mounting in new instances will take time, You can attach an EBS volume to any EC2 instance in the same Availability Zone. so lot of overhead to replicate in multiple AZ of volume + limitation of mounting on only 16instances C looks promising but again mounting on new instances will still take time which is downtime so not a good solution D is S3-IA with Availability 99.9 % while S3 standard is 99.99% B is highly available and can be accessed from any place and has unlimited storage

Answer is probably C. But we are making the assumption that the application cannot already natively read/write to S3.

Answer has to be C because they don't want to adjust code or website to use S3. A central NFS mount would be easy and could be done on the fly and/or transparently by changing fstab.
