Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 10 discussion

Definitely snowball for data transfer. As per the connectivity, 4 requirements here: Complete WITHIN a month, secure, consistent and BOTH companies need access. DirectConnect provides consistency, but it's not secure (it's private, that's different), it's a 1-to-1 direct connection and then you have up to 90 days to set it up (on average it takes more than 1 month, or at least that's what they said at the course). Site-to-Site VPN is secure and can be setup immediately in multiple sites. It's not consistent, but it can achieve consistency with Accelerated Site-to-Site VPN ("Accelerated Site-to-Site VPN makes user experience more consistent by using the highly available and congestion-free AWS global network.") So I'd go for Snowball and VPN (possibly Accelerated)

why not C? https://aws.amazon.com/directconnect/ AWS DirectConnect is secure + it should be more consistent than VPN

C- the question does not mention "cost effective"m therefore Snowball secures your data. Direct Connect is used for hybrid / consistent network connectivity between your on premises and cloud , with that been said it "bypasses the public internet" here you go. If the question has "cost effectiveness" mentioned yes then I would agree to use Site-to-Site VPN connection.

Snowball is one time transfer. Direct connection is only required when large amount data need to transfer. But considering the use case once the data is transferred using snow family device there is only operational connectivity is required. So the cost effective solution I believe is D

C is the correct answer

First you migrate all the data to the AWS with Snowball as each app has 50TB. Then, after setting everything up, you want to have “secure network connectivity with consistent throughput from their data centers to the applications”, meaning the Direct Connect needs to be used. Because we connect directly to AWS network, the throughput will be very good and security can be ensured with IPSec.

DX might take several weeks to months and the question explicitly say it needs to be done WITHIN a month so it is D source: https://docs.aws.amazon.com/whitepapers/latest/hybrid-connectivity/time-to-deploy.html

" require secure network connectivity with consistent throughput", I would choose direct connect over site-to-site vpn.

c is correct

My answer is A

I am going with C

Direct connect takes more then a month

For the initial transfer, snowball handles our current task. Then for a continued dedicated connection, Direct Connect will serve us better. No internet connection is needed and Availability and consistency is guaranteed

The AWS Direct Connect cloud service is the shortest path to your AWS resources. While in transit, your network traffic remains on the AWS global network and never touches the public internet. This reduces the chance of hitting bottlenecks or unexpected increases in latency. https://aws.amazon.com/directconnect/
