Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 232 discussion

Source for the answer?

A, is the Ans. Had this question yesterday. Just an additional information, for those using this environment, Please read AWS documentations, and practise a lot. I got my AWS re-certification yesterday with 850 score. I reviewed about 300 questions on this portal, But had only about 14 questions from this portal. The importance of this portal I will say is to reference AWS documentation on topics not well covered. Read them and practice the suggested solutions, this way you become well grounded. All the best.

In my opinion, it should be D as it has a Direct Connect line. The Q says LEAST amount of downtime, which means that whenever there is any downtime it should last of minimum amount of time. in case of natural disaster, when there is no internet connection to the datacenter, will not the Direct Connect line help in maintaining the backup process from on-prem to AWS? Open for suggestions.

I would go with B: If I understand this correctly the Storage gateway will be copying all of the data as a backup, which means the script would be in the backup data center. To a degree, this has to be the case because you can't wait for a natural disaster to then move your data over, if you do its too late. This is the same reason the Direct Connect does not make sense, this is not a question about data speed to the backup, the backup already has the data it just needs to turn on the EC2s and run off the backup data. Lastly, the only reason I would choose B over A is that B should boot faster as we won't have to wait for autoscaling to boot up to the demanded EC2s, we can just tell the script to boot up as many as we need by looking at current utilization. Yes I know I could set the minimum autoscale to whatever current utilization is, but still feels clunky given that it does not mention that they are currently using autoscaling.

Direct Connect is betweern a VPC in AWS and the current data center. How will the company benefit from DX when it loses connection the current data center?

And as per the question if DC is down, that means you have VPN and DX but site is down, so route 53 is useless as per you? As you say "for route 53 to work with hybrid environment it should have a connectivity with on-premises either through VPN of DX" and as per question "he company is not ready to fully migrate to the AWS Cloud, but it wants a failure environment on AWS in case the on-premises data center fails." Since as per you all answers have Route 53 and it won't work in situation, hence all answers are wrong?

question asked for LEAST amount of downtime. A = infrastructure already created. B = infrastructure will be created, may take additional few minutes. my 2 cents.

DC Doesn't mean migration: https://aws.amazon.com/directconnect/ AWS Direct Connect is a cloud service solution that makes it easy to establish a dedicated network connection from your premises to AWS. Using AWS Direct Connect, you create a private connection between AWS and your data center, office, or colocation environment. This can increase bandwidth throughput and provide a more consistent network experience than internet-based connections.
