Vce SAA-C03 Questions Latest

A VPC peering connection is a networking connection between two VPCs that enables users to route traffic between them using private IP addresses. Instances in either VPC can communicate with each other as if they are within the same network. A VPC peering connection can be createdbetween VPCs in the same or different AWS accounts and Regions1. By configuring a VPC peering connection between VPC A and VPC B, the solution can provide the required access most securely.

A. Create a DB instance security group that allows all traffic from the public IP address of the application server in VPC A. This solution willnot provide the required access most securely, as it involves exposing the DB instance to the public internet and relying on a single IP address for access control2.

C. Make the DB instance publicly accessible. Assign a public IP address to the DB instance. This solution will not provide the required access most securely, as it involves exposing the DB instance to the public internet and allowing any source to connect to it2.

D. Launch an EC2 instance with an Elastic IP address into VPC B. Proxy all requests through the new EC2 instance. This solution will not provide the required access most securely, as it involves creating an additional resource and configuring a proxy server that may introduce latency and complexity3.

Joining the FSx for Windows File Server file system to the on-premises Active Directory will allow the company to use the existing Active Directory groups to restrict access to the file shares, folders, and files after the move to AWS. This option allows the company to continue using their existing access controls and management structure, making the transition to AWS more seamless.

Amazon S3 is an object storage service that offers industry-leading scalability, data availability, security, and performance. You can use Amazon S3 to host static content for your website, such as HTML files, images, videos, etc. Amazon Elastic Container Service (Amazon ECS) is a fully managed container orchestration service that allows you to run and scale containerized applications on AWS. AWS Fargate is a serverless compute engine for containers that works with both Amazon ECS and Amazon EKS. Fargate makes it easy for you to focus on building your applications by removing the need to provision and manage servers. You can use Amazon ECS with AWS Fargate for compute power for your containerized application logic tier. Amazon RDS is a managed relational database service that makes it easy to set up, operate, and scale a relational database in the cloud. You can use a managed Amazon RDS cluster for the database tier of your application. This solution will simplify deployment and reduce operational costs for your three-tier application. References:

This answer is correct because it meets the requirements of optimizing cost and reducing the workload on the database. Amazon CloudFront is a content delivery network (CDN) service that speeds up distribution of your static and dynamic web content, such as .html, .css, .js, and image files, to your users. CloudFront delivers your content through a worldwide network of data centers called edge locations. When a user requests content that you’re serving with CloudFront, the request is routed to the edge location that providesthe lowest latency (time delay), so that content is delivered with the best possible performance. You can create an Amazon CloudFront distribution to host the static web contents from an Amazon S3 bucket, which is an origin that you define for CloudFront. This way, you can offload the requests for static web content from your EC2 instances to CloudFront, which can improve the performance and availability of your website, and reduce the cost of running your EC2 instances.
