A company has launched an Amazon RDS for MySQL DB instance. Most of the connections to the database come from serverless applications. Application traffic to the database changes significantly at random intervals. At times of high demand, users report that their applications experience database connection rejection errors.
Which solution will resolve this issue with the LEAST operational overhead?
Question:
A company hosts a public application on AWS. The company uses an Application Load Balancer (ALB) to distribute application traffic to multiple Amazon EC2 instances that are hosted in private subnets.
The company wants to authenticate all the requests by using an on-premises Active Directory Federation Service (AD FS). The company uses AWS Direct Connect to connect its on-premises data center to AWS.
Which solution will meet this requirement?
A global company runs a data lake application in the us-east-1 Region and the eu-west-1 Region in an active-passive configuration. Application data is stored locally in Amazon S3 buckets in each AWS Region. The bucket in us-east-1 is the primary active bucket that handles all writes. The company needs to ensure that the application has Regional fault tolerance. The company also needs the storage layer to provide a highly available active-active capability for reads across Regions. The storage layer must provide low latency access through a single global endpoint.
A company is building a mobile gaming app. The company wants to serve users from around the world with low latency. The company needs a scalable solution to host the application and to route user requests to the location that is nearest to each user.
Which solution will meet these requirements?
A company has several on-premises Internet Small Computer Systems Interface (iSCSI) network storage servers The company wants to reduce the number of these servers by moving to the AWS Cloud. A solutions architect must provide low-latency access to frequently used data and reduce the dependency on on-premises servers with a minimal number of infrastructure changes.
Which solution will meet these requirements?
A company is building a stock trading application in the AWS Cloud. The company requires a highly available solution that provides low-latency access to block storage across multiple Availability Zones.
A home security company is expanding globally and needs to encrypt customer data. The company does not want to manage encryption keys. The keys must be usable in multiple AWS Regions, and access to the keys must be controlled.
Which solution meets these requirements with the least operational overhead?
A solutions architect must design a database solution for a high-traffic ecommerce web application. The database stores customer profiles and shopping cart information. The database must support a peak load of several million requests each second and deliver responses in milliseconds. The operational overhead for managing and scaling the database must be minimized.
Which database solution should the solutions architect recommend?
An ecommerce company wants to collect user clickstream data from the company's website for real-time analysis. The website experiences fluctuating traffic patterns throughout the day. The company needs a scalable solution that can adapt to varying levels of traffic.
Which solution will meet these requirements?
A company is building a new web application that serves static and dynamic content from an API. Users will access the application from around the world. The company wants to minimize latency in the most cost-effective way.
Which solution will meet these requirements MOST cost-effectively?
A company runs production workloads in its AWS account. Multiple teams create and maintain the workloads.
The company needs to be able to detect changes in resource configurations. The company needs to capture changes as configuration items without changing or modifying the existing resources.
Which solution will meet these requirements?
A financial services company has a two-tier consumer banking application. The frontend serves static web content. The backend consists of APIs. The company needs to migrate the frontendcomponent to AWS. The backend of the application will remain on-premises. The company must protect the application from common web vulnerabilities and attacks.
A disaster response team is using drones to collect images of recent storm damage. The response team's laptops lack the storage and compute capacity to transfer the images and process the data.
While the team has Amazon EC2 instances for processing and Amazon S3 buckets for storage, network connectivity is intermittent and unreliable. The images need to be processed to evaluate the damage.
What should a solutions architect recommend?
A solutions architect needs to design a system to process incoming work items immediately. Processing can take up to 30 minutes and involves calling external APIs, executing multiple states, and storing intermediate states.
The solution must scale with variable workloads and minimize operational overhead.
Which combination of steps meets these requirements? (Select TWO.)
A company is hosting multiple websites for several lines of business under its registered parent domain. Users accessing these websites will be routed to appropriate backend Amazon EC2instances based on the subdomain. The websites host static webpages, images, and server-side scripts like PHP and JavaScript.
Some of the websites experience peak access during the first two hours of business with constant usage throughout the rest of the day. A solutions architect needs to design a solution that will automatically adjust capacity to these traffic patterns while keeping costs low.
Which combination of AWS services or features will meet these requirements? (Select TWO.)
