A company is migrating a monolithic on-premises .NET Framework production application to AWS. Application demand will grow exponentially in the next 6 months. The company must ensure that the application can scale appropriately.
The application currently connects to a Microsoft SQL Server transactional database. The company has well-documented source code for the application. Some business logic is contained within stored procedures.
A solutions architect must recommend a solution to redesign the application to meet the growth in demand.
Which solution will meet this requirement MOST cost-effectively?
Answer : D
A company hosts a public software as a service (SaaS) application on Amazon EC2 instances that run Linux. The EC2 instances are in multiple Availability Zones behind an Application Load Balancer. The application uses an Amazon RDS Multi-AZ database to store application data, including user sessions.
The company needs to minimize the latency that is involved in storing and accessing the user sessions.
Which solution will meet this requirement?
Answer : D

A company is running several applications in the AWS Cloud. The applications are specific to separate business units in the company. The company is running the components of the applications in several AWS accounts that are in an organization in AWS Organizations.
Every cloud resource in the company's organization has a tag that is named BusinessUnit. Every lag already has the appropriate value of the business unit name.
The company needs to allocate its cloud costs to different business units. The company also needs to visualize the cloud costs for each business unit.
Which solution will meet these requirements?
Answer : D
A company has a single AWS account. The company runs workloads on Amazon EC2 instances in multiple VPCs in one AWS Region. The company also runs workloads in an on-premises data center that connects to the company's AWS account by using AWS Direct Connect.
The company needs all EC2 instances in the VPCs to resolve DNS queries tor the internal.company.com domain to the authoritative DNS server that is located in the on-premises data center. The solution must use private communication between the VPCs and the on-premises network. All route tables, network ACLs. and security groups are configured correctly between AWS and the on-premises data center.
Which combination of actions will meet these requirements? (Select THREE.)
Answer : C, E
A company has implemented a new security requirement According to the new requirement, the company must scan all traffic from corporate AWS instances in the company's VPC for violations of the company's security policies. As a result of these scans the company can block access to and from specific IP addresses.
To meet the new requirement, the company deploys a set of Amazon EC2 instances in private subnets to serve as transparent proxies The company installs approved proxy server software on these EC2 instances The company modifies the route tables on all subnets to use the corresponding EC2 instances with proxy software as the default route The company also creates security groups that are compliant with the security policies and assigns these security groups to the EC2 instances
Despite these configurations, the traffic of the EC2 instances in their private subnets is not being properly forwarded to the internet.
What should a solutions architect do to resolve this issue?
Answer : A
Identify Proxy EC2 Instances:
Determine which EC2 instances in the private subnets are running the proxy server software.
Disable Source/Destination Checks:
For each of these EC2 instances, go to the AWS Management Console.
Navigate to the EC2 dashboard, select the instance, and choose 'Actions' > 'Networking' > 'Change Source/Dest. Check'.
Disable the source/destination check for these instances.
Disabling source/destination checks allows the EC2 instances to route traffic appropriately, enabling them to function as network appliances or proxies. This ensures that traffic from other instances in the private subnets can be routed through the proxy instances to the internet, meeting the company's security requirements.

A company has developed a new release of a popular video game and wants to make it available for public download The new release package is approximately 5 GB in size. The company provides downloads for existing releases from a Linux-based publicly facing FTP site hosted in an on-premises data center The company expects the new release will be downloaded by users worldwide The company wants a solution that provides improved download performance and low transfer costs regardless of a user's location
Which solutions will meet these requirements'?
Answer : C
Create an S3 Bucket:
Navigate to Amazon S3 in the AWS Management Console and create a new S3 bucket to store the game files. Enable static website hosting on this bucket.
Upload Game Files:
Upload the 5 GB game release package to the S3 bucket. Ensure that the files are publicly accessible if required for download.
Configure Amazon Route 53:
Set up a new domain or subdomain in Amazon Route 53 and point it to the S3 bucket. This allows users to access the game files using a custom URL.
Use Amazon CloudFront:
Create a CloudFront distribution with the S3 bucket as the origin. CloudFront is a content delivery network (CDN) that caches content at edge locations worldwide, improving download performance and reducing latency for users regardless of their location.
Publish the Download URL:
Use the CloudFront distribution URL as the download link for users to access the game files. CloudFront will handle the efficient distribution and caching of the content.
This solution leverages the scalability of Amazon S3 and the performance benefits of CloudFront to provide an optimal download experience for users globally while minimizing costs.
