Design High-Performing Architectures

A company is designing a highly scalable web application. The application will receive HTTP and HTTPS traffic and needs to route requests to different target groups based on the URL path. Which AWS service should the solutions architect recommend?

An application runs on Amazon EC2 instances in an Auto Scaling group. The application experiences unpredictable traffic spikes. The solutions architect wants to ensure that the average CPU utilization of the instances stays around 50%. Which scaling policy should be used?

A company is building a decoupled application where a producer sends messages to a queue, and a consumer processes them. The order of the messages is critical, and duplicate processing must be avoided. Which AWS service should be used?

A serverless application uses Amazon API Gateway, AWS Lambda, and Amazon DynamoDB. During a marketing campaign, traffic spikes to 10,000 requests per second. Users report receiving 503 Service Unavailable and 429 Too Many Requests errors. Which TWO actions should the solutions architect take to resolve these issues? (Select TWO.)

A company is migrating a containerized application to AWS. The company wants to run the containers without having to manage the underlying servers or clusters. Which compute service should the solutions architect recommend?

A global media company allows users to upload large video files to an Amazon S3 bucket located in the us-east-1 Region. Users in Australia are experiencing slow upload speeds. What is the MOST effective way to improve the upload performance for these users?

A database running on an Amazon EC2 instance requires a block storage volume that can provide 15,000 IOPS. The workload is consistent, and cost is a consideration, but performance must be guaranteed. Which Amazon EBS volume type is the MOST cost-effective choice that meets the performance requirement?

A company has a read-heavy application backed by Amazon DynamoDB. The application is experiencing high latency during peak hours due to the volume of read requests. The solutions architect needs to implement a caching layer to improve read performance to microsecond latency. Which TWO solutions can achieve this? (Select TWO.)

A company is deploying a tightly coupled High Performance Computing (HPC) application on Amazon EC2. The application requires the lowest possible network latency and highest network throughput between instances. How should the EC2 instances be deployed?

A developer has written an AWS Lambda function that processes images. The function is taking too long to execute, and the developer wants to improve its CPU performance. How can the developer increase the CPU power allocated to the Lambda function?

A company needs to run hundreds of thousands of batch computing jobs. The jobs are packaged as Docker containers. The company wants a service that will dynamically provision the optimal quantity and type of compute resources (e.g., CPU or memory optimized instances) based on the volume and specific resource requirements of the submitted jobs. Which service should be used?

A media company is rendering high-resolution 3D animations. The rendering software runs on Amazon EC2 instances and requires extreme network performance and low latency between nodes. Which TWO features should the solutions architect use to maximize network performance? (Select TWO.)

A company uses Amazon DynamoDB to store user activity logs. The partition key is the UserID, and the sort key is the Timestamp. A small number of highly active users are causing ProvisionedThroughputExceededException errors, even though the overall table capacity seems sufficient. What is the MOST likely cause of this issue?

A data analytics team needs to run complex SQL queries against petabytes of structured and semi-structured data stored in Amazon S3. They want a serverless solution where they only pay for the queries they run, without managing any infrastructure. Which service should they use?

A company is developing a new SaaS application. The database workload is highly unpredictable, with periods of zero activity followed by sudden, massive spikes in traffic. The company wants a relational database that scales compute capacity instantly to meet demand and scales down to save costs. Which TWO database options meet these requirements? (Select TWO.)

A multiplayer gaming company has users worldwide connecting to game servers hosted in the eu-central-1 Region. Users in Asia are experiencing high latency and packet loss due to the unpredictable nature of the public internet. How can a solutions architect improve the network performance for these users?

A company has 50 VPCs across multiple AWS Regions. The company needs to establish network connectivity between all VPCs. Which solution provides the MOST scalable and high-performing architecture with the LEAST operational overhead?

A company is migrating a large database from its on-premises data center to AWS. The migration requires a dedicated, high-speed network connection. However, the company's security policy mandates that all data in transit must be encrypted using IPsec. How can a solutions architect meet both requirements?

An application runs on EC2 instances in an Auto Scaling group behind an Application Load Balancer (ALB). Instances are occasionally failing, but the Auto Scaling group is not replacing them because the EC2 status checks still pass. How can this be fixed?

A company has a single EC2 instance hosting a legacy application that cannot be load balanced. If the instance fails, a new one must be launched automatically, but the application requires a static IP address that clients have whitelisted. How can this be achieved?

A company is running a high-performance computing (HPC) workload that requires massive amounts of memory to process large datasets in real-time. Which Amazon EC2 instance family should they choose?

A global media company allows users to upload large video files to an Amazon S3 bucket located in the us-east-1 region. Users in Australia are experiencing slow upload speeds. How can the solutions architect improve the upload performance?

A company is migrating a read-heavy application to AWS. They want to implement an in-memory caching layer to reduce the load on their Amazon RDS database. The caching solution must support complex data structures (like sorted sets) and Multi-AZ high availability. Which TWO actions should they take? (Select TWO.)

An application uses Amazon DynamoDB to store product catalog data. During flash sales, the application experiences massive read spikes, causing ReadCapacityUnit (RCU) throttling and increased latency. The application requires microsecond read latency. What is the BEST solution?

A startup is building an application with unpredictable, intermittent traffic. They need a relational database that can automatically scale compute capacity up and down based on application demand, and pause during periods of inactivity. Which service should they use?

A company has an application hosted on EC2 instances in the eu-west-1 region. Users globally are experiencing high latency due to internet routing. The company wants to route traffic over the AWS global network to improve performance. Which service should they use?

A database administrator is provisioning storage for a high-performance relational database on Amazon EC2. The database requires sustained performance of 64,000 IOPS. Which TWO Amazon EBS volume types can meet this requirement? (Select TWO.)

A company is using Amazon EFS for a big data analytics workload. Hundreds of EC2 instances are reading and writing to the file system simultaneously. The application is experiencing high latency. Which EFS performance mode should be used?

A company has petabytes of historical data stored in Amazon S3. They want to query this data using standard SQL without loading it into a database. They also want to join this S3 data with frequently accessed data stored in their Amazon Redshift cluster. What is the MOST efficient solution?

A company has two VPCs (VPC A and VPC B) in the same AWS Region. They need to establish a private, high-bandwidth network connection between the two VPCs. The solution must minimize costs and avoid single points of failure. Which TWO actions should they take? (Select TWO.)
