Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 464 discussion

Question is related to Db storage performance and options are network related. Something wrong with this site.. correct question is On its website, a business keeps a searchable store of things. The data is stored in a table with over ten million rows in an Amazon RDS for MySQL database. The database is stored on a 2 TB General Purpose SSD (gp2) array. Every day, the company's website receives millions of changes to this data. The organization found that certain activities were taking ten seconds or more and concluded that the bottleneck was the database storage performance. Which option satisfies the performance requirement? A. Change the storage type to Provisioned IOPS SSD (io1). B. Change the instance to a memory-optimized instance class. C. Change the instance to a burstable performance DB instance class. D. Enable Multi-AZ RDS read replicas with MySQL native asynchronous replication. Ans is A.

Answer should be (A), as they wish to reduce the Direct Connect charges and that it should not be accessible over the internet, the only choice would be is to create an interface endpoint.

It shall be A. The reason is EC2 instances cannot access internet. SO VPC endpoint is a solution

It has a default route back to the on-premises data center for outbound internet access.

Answer:B I think it helps in this scenario to draw it out and determine what is the component that needs to be addressed since the question/scenario is fuzzy at best. DC-----AWS DX------EC2----S3 Images are sent via DX to the AWS cloud platform and that cost needs to be reduced. The introduction of a NAT gateway with a public IP address would allow the DC to connect to the AWS platform where just an internet flat charge would apply. Using the Nat gateway also allows for the requirement that the EC2 instances are not accessible directly through the internet as private addresses are hidden.

Compared between "Access through an internet gateway" and "Access through a gateway endpoint" , Gateway endpoints is better. https://docs.aws.amazon.com/vpc/latest/privatelink/gateway-endpoints.html

VPC endpoint...

Ans A. You have to use a Gateway endpoint for S3 to be accessed from within the vpc. Currently it is going via the on prem Internet to S3 adding to DirectConnect charges and also getting exposed to Internet. so A VPC endpoint is the MOST closest answer from the given options; however GWY EP is the most accurate one as this is a type of VPC EP.

Option A is incorrect. VPC endpoint use Non Relational DB to connect privately.

I go with A. https://aws.amazon.com/blogs/architecture/reduce-cost-and-increase-security-with-amazon-vpc-endpoints/ A VPC endpoint allows you to privately connect your VPC to supported AWS services. It doesn’t require you to deploy an internet gateway, network address translation (NAT) device, Virtual Private Network (VPN) connection, or AWS Direct Connect connection. Endpoints are virtual devices that are horizontally scaled, redundant, and highly available VPC components. VPC endpoints allow communication between instances in your VPC and services, without imposing availability risks or bandwidth constraints on your network traffic. You can optimize the network path by avoiding traffic to internet gateways and incurring cost associated with NAT gateways, NAT instances or maintaining firewalls. VPC endpoints also provide you with much finer control over how users and applications access AWS services.

Wonder how you guys can match the question and choices, to me the choices mostly not matching with the question. Is the idea here to practice with trick question?

As I read the question (the right question thats goes with the options), the S3 issue is already addressed (the images are stored in an Amazon S3 bucket) maybe even with a GW. The direct connect is then used to send images to EC2 and for other outbound traffic from EC2. For me it's B to decrease the usage of the direct connect connection.

The real question is: What are the actual answers to the question "A firm maintains a searchable inventory of items on its website. ..."

Here is the right question: A company recently launched a new service that involves medical images. The company scans the images and sends them from its on premises data center through an AWS Direct Connect connection to Amazon EC2 instances After processing is complete , the images are stored in an Amazon S3 bucket . A company requirement states that the EC2 instances cannot be accessible through the internet The EC2 instances run in a private subnet , which has a default route back to the on premises data center for outbound internet access. Usage of the new service is increasing rapidly . A solutions architect must recommend a solution that meets the company ' s requirements and reduces the Direct Connect charges . Which solution accomplishes these goals MOST cost -effectively ?

answers not related to question!

These answers are not even relevant to this question. Question is talking about database performance whereas answers are talking about Direct connect and NAT. The whole test paper is messed up by examtopic. Wrong answers are attached to wrong question hence it is become completely useless to use these tests. Can Examtopic please fix it urgently.

The correct question: A company recently launched a new service that involves medical images. The company scans the images and sends them from its on-premises data center through an AWS Direct Connect connection to Amazon EC2 instances.
