Domain 2.5: Performance

A global media company streams video content to users worldwide. They are experiencing high latency and buffering issues in regions far from their primary AWS Region. Which combination of services will BEST optimize content delivery performance?

A high-frequency trading application runs on EC2 instances and requires the absolute lowest possible network latency and highest packet per second (PPS) performance between nodes in the same VPC. Which networking feature MUST be utilized?

An application uses Amazon Kinesis Data Streams to ingest high-throughput telemetry data. During peak hours, the application experiences `ProvisionedThroughputExceededException` errors. The architect needs to resolve this automatically without losing data. What is the BEST solution?

A company is migrating a large, monolithic database to AWS. The database is highly transactional and requires sub-millisecond latency for read operations. The data model is highly relational and cannot be refactored into NoSQL. Which caching strategy should be implemented to meet the performance requirements?

A media company is launching a global video streaming platform. They need to ensure the lowest possible latency for users worldwide, protect against DDoS attacks, and cache static assets at the edge. Which THREE AWS services should be part of the architecture? (Select THREE)

An architect is designing a high-performance computing (HPC) cluster on AWS. The application requires sub-millisecond network latency and high packet-per-second performance between EC2 instances. Which THREE configurations are required to achieve this? (Select THREE)

An application requires a database that can handle millions of requests per second with microsecond latency. The data model is a simple key-value store. Which AWS database service is MOST appropriate?

A global media company serves video content to users worldwide. They need to minimize latency and reduce the load on their origin servers located in us-east-1. Which combination of services provides the BEST performance?

A gaming application requires a database that can handle millions of read/write requests per second with single-digit millisecond latency. The schema is flexible and relationships between data entities are minimal. Which database service is BEST suited?

A high-performance computing (HPC) cluster runs on EC2 instances. The nodes need to communicate with each other with the absolute lowest latency and highest throughput possible, bypassing the OS kernel. Which networking feature should be used?

An e-commerce platform uses Amazon DynamoDB as its primary database. During flash sales, read traffic spikes unpredictably, causing read throttling and degraded performance. The architecture team wants to improve read performance with microsecond latency while minimizing changes to the application code. Which solution is MOST appropriate?

A media company streams video content globally. They use Amazon S3 for storage and Amazon CloudFront for delivery. Recently, they noticed a spike in S3 egress costs. Investigation reveals that users in certain countries are bypassing CloudFront and accessing the S3 bucket directly via its public URL. How can the Architect enforce that all access goes through CloudFront, preventing direct S3 access?

A company runs a high-performance computing (HPC) workload on a cluster of Amazon EC2 instances. The instances need to communicate with each other with the absolute lowest possible latency and highest packet rate. The workload is tightly coupled and runs in a single Availability Zone. Which network configuration should the Architect use?

A global SaaS provider is re-architecting their multi-tenant application. Currently, all tenants share a single Amazon RDS for PostgreSQL database, leading to 'noisy neighbor' performance issues and complex data isolation. The business wants to move to a siloed tenant model where each tenant has their own database. They need to provision new tenant databases in seconds, scale compute independently of storage, and minimize storage costs for tenants with sparse data. Which combination of services and features should be used? (Select TWO)

An application requires a caching layer to improve database read performance. The cache must support complex data structures (lists, sets, sorted sets), provide sub-millisecond latency, and be highly available across multiple Availability Zones with automatic failover. Which AWS service meets these requirements?

A media streaming company stores petabytes of video files in Amazon S3. They use Amazon CloudFront to deliver the content globally. To protect their content, they want to ensure that users can only access the videos if they have a valid subscription. The authorization logic is complex, requires querying an external database, and must be executed as close to the user as possible to minimize latency. Which solution meets these requirements?

A global e-commerce company is experiencing performance issues with their product catalog API. The API is hosted on Amazon EC2 instances behind an Application Load Balancer (ALB) in the us-east-1 region. Users in Asia and Europe experience high latency. The product catalog data changes infrequently (once a day). The Architect wants to improve global read performance and reduce the load on the EC2 instances. Which combination of actions should the Architect take? (Select TWO)

A company has a fleet of Amazon EC2 instances running a legacy application that requires a shared file system. The instances are spread across two Availability Zones. The application is highly sensitive to latency and requires the highest possible IOPS. The data must be highly available and survive an AZ failure. Which storage solution should the Architect choose?

A media company is migrating its video rendering workload to AWS. The workload is highly parallelizable, fault-tolerant, and requires massive amounts of compute power for short bursts. The company wants to minimize compute costs. They also need a shared file system to store the raw video files that provides high throughput and can be accessed by thousands of EC2 instances simultaneously. Which combination of services should the Architect choose? (Select TWO)

A high-performance computing (HPC) application runs on a cluster of EC2 instances. The application requires extremely low latency and high throughput network communication between the instances. Which networking configuration should the architect use?

A read-heavy news website uses Amazon Aurora MySQL. During breaking news events, the database CPU spikes to 100% due to millions of identical read queries, causing the site to crash. How can the architect improve performance with minimal code changes?

An application serves dynamic, personalized content to users globally. The content cannot be cached. Users in Asia report high latency when accessing the application hosted in us-east-1. How can the architect improve network performance for these users?

A company is migrating a legacy application to AWS. The application uses a proprietary file system that requires a POSIX-compliant shared file storage accessible by hundreds of Linux EC2 instances simultaneously. The storage must support high throughput and low latency. Which combination of services and configurations should be used? (Select TWO)

A global gaming company uses Amazon DynamoDB for player profiles. Players are distributed worldwide. The company wants to ensure that players experience single-digit millisecond latency when reading and writing their profiles, regardless of their location. Which DynamoDB feature should be used?
