A Solutions Architect is building a containerized .NET Core application that will run in AWS Fargate. The backend of the application requires Microsoft SQL Server with high availability. All tiers of the application must be highly available. The credentials used for the connection string to SQL Server should not be stored on disk within the .NET Core front-end containers. Which strategies should the Solutions Architect use to meet these requirements?
An organization is having an application which can start and stop an EC2 instance as per schedule. The organization needs the MAC address of the instance to be registered with its software. The instance is launched in EC2-CLASSIC. How can the organization update the MAC registration every time an instance is booted?
A company operates a group of imaging satellites. The satellites stream data to one of the company’s ground stations where processing creates about 5 GB of images per minute. This data is added to network-attached storage, where 2 PB of data are already stored.
The company runs a website that allows its customers to access and purchase the images over the Internet. This website is also running in the ground station. Usage analysis shows that customers are most likely to access images that have been captured in the last 24 hours.
The company would like to migrate the image storage and distribution system to AWS to reduce costs and increase the number of customers that can be served. Which AWS architecture and migration strategy will meet these requirements?
In AWS, which security aspects are the customer's responsibility? (Choose four.)
Which of the following AWS services can be used to define alarms to trigger on a certain activity, such as activity success, failure, or delay in AWS Data Pipeline?
A greeting card company recently advertised that customers could send cards to their favorite celebrities through the company's platform. Since the advertisement was published, the platform has received constant traffic from 10,000 unique users each second.
The platform runs on m5.xlarge Amazon EC2 instances behind an Application Load Balancer (ALB). The instances run in an Auto Scaling group and use a custom AMI that is based on Amazon Linux. The platform uses a highly available Amazon Aurora MySQL DB cluster that uses primary and reader endpoints. The platform also uses an Amazon ElastiCache for Redis cluster that uses its cluster endpoint. The platform generates a new process for each customer and holds open database connections to MySQL for the duration of each customer’s session. However, resource usage for the platform is low. Many customers are reporting errors when they connect to the platform. Logs show that connections to the Aurora database are failing. Amazon CloudWatch metrics show that the CPU load is low across the platform and that connections to the platform are successful through the ALB.
Which solution will remediate the errors MOST cost-effectively?
A company is running several large workloads on Amazon EC2 instances. Each EC2 instance has multiple Amazon Elastic Block Store (Amazon EBS) volumes attached to it. Once each day, an AWS Lambda function invokes the creation of EBS volume snapshots. These snapshots accumulate until an administrator manually purges them.
The company must maintain backups for a minimum of 30 days. A solutions architect needs to reduce the costs of this process. Which solution meets these requirements MOST cost-effectively?
A company that provides wireless services needs a solution to store and analyze log files about user activities. Currently, log files are delivered daily to Amazon Linux on an Amazon EC2 instance. A batch script is run once a day to aggregate data used for analysis by a third-party tool. The data pushed to the third-party tool is used to generate a visualization for end users. The batch script is cumbersome to maintain, and it takes several hours to deliver the ever- increasing data volumes to the third-party tool. The company wants to lower costs, and is open to considering a new tool that minimizes development effort and lowers administrative overhead. The company wants to build a more agile solution that can store and perform the analysis in near-real time, with minimal overhead. The solution needs to be cost effective and scalable to meet the company’s end-user base growth. Which solution meets the company’s requirements?
A company wants to improve cost awareness for its Amazon EMR platform. The company has allocated budgets for each team’s Amazon EMR usage. When a budgetary threshold is reached, a notification should be sent by email to the budget office’s distribution list. Teams should be able to view their EMR cluster expenses to date. A solutions architect needs to create a solution that ensures the policy is proactively and centrally enforced in a multi-account environment. Which combination of steps should the solutions architect take to meet these requirements? (Choose two.)
A company has an Amazon VPC that is divided into a public subnet and a private subnet. A web application runs in Amazon VPC, and each subnet has its own NACL. The public subnet has a CIDR of 10.0.0.0/24. An Application Load Balancer is deployed to the public subnet. The private subnet has a CIDR of 10.0.1.0/24. Amazon EC2 instances that run a web server on port 80 are launched into the private subnet. Only network traffic that is required for the Application Load Balancer to access the web application can be allowed to travel between the public and private subnets. What collection of rules should be written to ensure that the private subnet’s NACL meets the requirement? (Choose two.)
